Guys...help please...Suddenly my browser doesn't functionally normal (it won't browse the internet) the strange things is my internet connection is normaly (messenger is normal, when i browse with program such as i tune or Windows media player everything is normal ) the problem is when i browse with my Firefox or Internet Explorer there are message "Contain no data" (which means the browser report that i don't have any connection with the Internet) but when I stop the On-Access Protection Control everything go back to normal...
Any suggestion................................. ???
Thanks before.....:D ;)

When I stop the On-Access Protection Control everything go back to normal...
Or you're trying to see abnormal webpages and this does not occur with all pages.
Or you're infected and you shouldn't disable the antivirus :o
Try cleaning your temporary files.
Schedule a boot time scanning with avast. Start avast! > Right click the skin > Schedule a boot-time scanning. Select for scanning archives. Boot.
Use a-squared (http://www.emsisoft.com/en/software/free/), ewido (http://www.ewido.net/en/) or Spyware Terminator (http://www.spywareterminator.com/) (trojan removers).
Let us know the results ;)
-
What is your firewall ?
Does it allow ashWebSv.exe to access the internet ?
when i browse with my Firefox or Internet Explorer there are message "Contain no data"
This and the fact that it works when the web shield is paused would tend to indicate firewall blocking.

I already do what u sugest ( cleaning the temporary files & scanning archives) no viruses found and stiil no changes, I still can't browse when the "ON-Access Protection" swtiched ON but when its OFF Yes! I can browse normally but without protection....any more suggestion.....
-
Did you read my post ?
-
What is your firewall ?
Does it allow ashWebSv.exe to access the internet ?
I'm using standatr win xP sp2 firewall, yes its allow ashWebSv.exe to access internet, and I already mention I only had the problem when I switch on the On-Access Protection from AVAST, but when I disabled it everthing normal.....so I have conclusion its was because of the AVAST not the Firewall
when i browse with my Firefox or Internet Explorer there are message "Contain no data"
This and the fact that it works when the web shield is paused would tend to indicate firewall blocking.
Yes that was I think 1st time, but now its clear when I'm disable the Avast there are no problem at all when I using my browser, and I already try to Pause the Avast provider 1 by 1 to find which one is cause the problem but there are still problem even I already pause all the provider,
So right now I Only can browse the internet when the Avast protection disable..... :-[
Plz any more suggestion.....

See Image are both of these in the XP firewall Exclusions and are they ticked ?
If so I'm at a loss as to what what might be blocking ashWebSv.exe
In order for this to happen there would have to be some form of interaction with another program, disable one and it will work, however, that doesn't give an indication of what is truly at fault.
Do you use a router ?
Do you use a proxy program or is this a requirement of your ISP, etc. ?
As you mention 'Suddenly my browser doesn't functionally normal (it won't browse the internet)' have you changed anything recently, new program, etc.
Edit, Ignore the bit in the image about the firewall being off, I use Outpost Pro. You could switch off the XP firewall, for a quick test with web shield enabled and see if that works, then enable the firewall.

Looks new changes happening, I have just restore my default firewall setting, and every my last configuration setting at the Avast program ,......
Right now my browser normal if only I disabled the "Web Shield" at the On Access Protection setting.........Is that normal.....? because when I try enabled it, the browser won't work again.....
Thanks before.....man :D

:) Hi "14" :
You may have a problem that is NOT a "virus", but some-
thing more serious, that is NOT detected by Avast .
Other than Avast & your inadequate XP SP2 "firewall",
what other security program(s) do you have on your
computer ? If you do NOT have "Ewido", as Tech
suggested, would encourage you do do so, since it
"specializes" in more "serious" malware, like trojans,
worms, keyloggers, generic dialers, etc in detecting &
quarantining them .

Ewido I already check the website....and its not free dude, Its kind of expensive, Can u suggest something Free maybe ????:D
-
:) Hi "14" :
I realize the ewido website can be misleading as to the
program; one starts off by downloading the program,
which includes "real-time protection" and automatic
updates for a "trial" period. Let the "trial" end without
purchasing the program ; it "reverts" to the "free" version
where you "lose" the real-time protection and automatic
Updates. I have for a long time, been using the "free"
Ewido .
-
Okay,I'll try to download Ewido 1st, but still do any one have exact answer....Why that When I enabled (switch to normal position) The Web Shield On-Access Protection, I can't browse any website with my FireFox and IE...?????
-
Why that When I enabled (switch to normal position) The Web Shield On-Access Protection, I can't browse any website with my FireFox and IE...?????
Is ashwebsv.exe allowed to receive 'inbound' connections from the Internet into the XP SP2 firewall?
The real free version of ewido anti-spyware, with real-time protection and automatic online update disabled by default, i.e., the on-demand scanner only (without need to wait the trial period to expire) is here: http://free.grisoft.com/doc/ewido-anti-spyware-free/lng/us/tpl/v5

Hi 14,
You can also scan your computer online and clean it, or download ewido anti-spyware micro scanner http://www.ewido.net/en/onlinescan/ ;)

Microsoft has Windows Defender which is free.

:'(
I already scan my Computer with Ewido, The Result is clean, and still I can not use my browser when the Web Shield provider run, Any one can Help.... ???
OR I should change my Anti Virus program....???

Please, activate logging in WebShield:
1. Edit <avast>\data\avast4.ini file
2. Find the section [WebScanner]
3. Add the line:
EnableLogging=1
4. Restart Web Shield in XP (terminate and start again) or whole PC in case of Win98
5. Browse (trying to access some webpages)
The log file are <avast>\data\log\ashwebsv.log and ashwebsv.ws.
They would be accessible when WebShield is terminated again.
Post them here or send by mail to rypacek@asw.cz
After that, disable the logging to avoid a big log file.

I too began having problems with any browser but am receiving "The connection was reset" errors on any "http" sites. If I go to an "https" site everything was OK.
I found that either terminating WebShield or removing the 80 from "Redirected HTTP port(s)" field it worked also.
I have created a log such as rypace asked for from you and maybe will help.

Connection instability?
Can you post a screenshot of the error message?
Do you have any other antivirus, security program, etc., installed in this computer?
WebShield does not scan https traffic... either if you remove port 80 from scanning is the same as disable WebShield...
Can you generate the log file as posted before?

Hi Tech, ;)
I dont think that this is problem coused by other antivirus, security program, etc..I had this problem with the browser yesterday too, but now it's gone, no problemo, nada.Before the problem start i scaned with Ewido and it found this Downloader.Adload.ch and i deleted it, and after that i scaned with Ad Aware it didnt find anything, so i run CCleaner and scan with Avast. The message that i was receiving was "The connection was reset while loading the page" or something like that, also it was written to check the conection wich was ok and enabled, and also to check if i use firewall is the Firefox permited to conect to internet.Exept that there was unusual high activity with the firewall and that i was not able to browse in periods of few minutes to about 30 minutes.I did not do any changes and now the browser is working fine with no problems. ??? any idea what happend :P
-
Guys I still had problem with my browser, It won't work when the web-shield turn on, But Its normal when the web-shield service terminated........
1st time I assuming it was the firewall, but with the firewall disabled it won't work too if the web-shield service turn on, so its not the firewall...... ???
My XP SP2 firewall setting screen shoot
(http://i6.photobucket.com/albums/y227/T4ngky/mywinsp2Firewall.jpg)
2nd I got advice if maybe there is some malware that causes the browser won't work if the web-shield turn on, but i Already scanned my computer with Ewido and everything is fine....
So Is it possible there sometihing incorrect with my Avast Setting.....but which part ??? :-\
And I already try add the line : EnableLogging=1 at the [Webscanner] section, on the avast4.ini but still I can't browse if web-shield service turn on.....
So please guys, Any more Advice ????
This what it show when I try to browse with the webshield turn on

I already done what you advice me but still It won't solve my browser problem, I still Only can browse if the Web-Shield turn off
and the log file ashwebsv.log and ashwebsv.ws are empty ( 0 kb) nothing there
-

Can you generate the log file as posted before?
I have exactly the same problem as described here (thats why i was searching this forum). On acces webshield scanner on: no internet.
Turning it off makes my internet work fine!
As you said, it does not scan https sites. And indeed; when i turn the on acces webshield on, not any website works, EXCEPT the https websites.
I have no idea what the problem is here...maybe some firewall from a router?
-
The log file ashwebsv.log and ashwebsv.ws are empty ( 0 kb) nothing there
But, did you activate logging in WebShield as I've posted before?
Did WebShield work at least one time in your computer?
Do you use any annonimizer (proxy) application?
WebShield does not scan https because the traffic is encrypted and avast cannot know the encryption... otherwise, anybody will know it and steal your bank data 8)
-
But, did you activate logging in WebShield as I've posted before?
What do you mean by " Activate logging in Webshield" If its starting the webshield services : Yes, I already done that and When I started the service, I Can't browse the Http at all. :-[
Did WebShield work at least one time in your computer?
How would I notice it ? I Can't use my browser at all......
Do you use any annonimizer (proxy) application?
what is that ? Can you give me an example, because I'm not an advanced computer user

seems like we got a new teammember:
http://forum.avast.com/index.php?topic=23480.0 ;D
It's the same problem!
-
One problem leads to another. Based on advice above I'm doing an Ewido scan now, but none of the buttons on Ewido screens have any text, so I have to try to remember which button does what.
-
same here, and I'm tracking this post juz in case a solution pops up :-[
Internet services working when the web access control is on:
- e-mail (ofcourse not webmail) both pop and smtp
- ping, both in dns and in ip addy
- telnet, both dns/ip
- tracert
- all TCP / UDP services running in background which includes IM, download managers, etc
Internet services NOT working when web access control is on:
http (no proxy, port is default 80)
Browser: Mozilla Firefox 1.5.0.6, IE7 beta 3
Error messages? Naah, just the plain old page cannot be displayed.
OS: WINXP SP2
Scripts running? Yes, but none pertaining to internet nor LAN (this is my only PC)
What I already did: ;)
cleaned cookies and temp
scanned adaware through ewido (found 32, cleaned em, same problem)
added avast in windows firewall exceptions list
added same in trust lists
BTW, if it needs mentioning AVAST didn't find any viruses on system and she is the only anti-virus on my system, though I do have Ewido
checked file permissions --> found two errors, fixed em using using WMIdiag command in cmd
when I'm just about to give up, I went to this forum and voila, found I'm not the only guy in the planet who's having this problem.
Cheers ;D
Temporary solution: well, I have that web access control turned off 8)
Don't know what else to do... ???
-
:) Hi Jeff :
One of our regular "Helpers" reported having problems with IE7, Beta 3;
perhaps if you removed it & went back to IE6, it may help !?
I do NOT believe it is wise to have "Beta" products on a computer UNLESS
one is a very "Advanced" computer person .
-
I'm on IE 6, have never installed IE 7, mainly use Firefox and have the problem, so don't think going back to IE 6 would be anything other than another exercise in futility.
-
Thanks for the suggestion. 8)
I'll try your suggestion (removing my IE 7 beta 3) within the next 12 hours (still have tsomething else to do). Regarding problems, I did had quite a few problems regarding IE 7 beta 3, thought I fixed 'em except for this web access control thingy.
Having said that, I don't think the problem is with IE7 because my Mozilla firefox 1.5.0.6 is also not showing webpages when the web access control is on in Avast. I'll try your suggestion within the next 12 hours (got something else to do) and I'll just edit this post if it worked. Thanks ;)
-
Quite sure it ain`t a problem of IE7 beta.
I never tried IE7, but i have the problem.
I`m also quite sure it ain`t a problem of my home network; an other computer in the network which is also running win xp with avast doesnt have the problem.
-
I'm also seeing this on my Wifes Windows 2000 laptop. Everything was fine. Installed AVAST, still fine. Updated Avast. No connection.
I'm fairly sure it's Avast. I'll un-ibstall and post the results.
-
Well un-installed and still no connection. Deleted my network setup and re-added it. Workes now. Re-installed and still works. So..................
Inconclusive.
-
Hi ya all!
I have a bit of input. Have win98 gold (not se). Same problem, only my connection was really slow. I stopped by going to start, run, msconfig, click OK, and the click the start up tab and uncheck avast running programs.
The problem stopped right away---just like that.
Cant use the on-access protection though! Is that the right name?
Anyway, it most certainly appears to be the interworking of these avast running programs (a and I icons).
Hope this helps.
Diligent.
-
Same problem, only my connection was really slow.
You can disable WebShield only but you can't disable all avast protection or, like you can see, you'll be unprotected ;D
I do NOT recommend messing your installation through msconfig tool ;)
-
I had the same problem as well. Vista Ultimate, no proxy, disabled FW, opened port 12080 on my router, still couldn't access the web (all other network functions were fine) without disabling the web shield. Apparently, even though I had the trial of McAfee Security Center turned off (all options disabled), which came bundled with the computer, it was causing the problem. I uninstalled McAfee and *poof!* all is working. I even removed my new port setting on the router because it just wasn't needed. I'd suggest checking to see if there are ANY other security software utilities installed, even if they're disabled, and uninstall them to get to the cause of the issue.
-
Thanks for the response TECH!
Could you please expand a bit?
I do want to be protected, but with a win98 I have learned to be very--very cautious, particularly as to running progs.
So how do I disable webshield only? Based on the FAQ info this might be a problem in my own individual situation.
Once I do so, safely, I'll sure unchecked the avast, to see what happens. Thanks.
I do note, though, that the connection or downloading problem I see in this string is not solved. I was and am really trying to help!!! And do appreciate YOUR help!
Diligent :-\

I know you are specifically asking for Tech's help, but I can quickly tell you how to disable the web shield.
1. Right-click on the "avast! On-Access Scanner" icon in the system tray (near the clock) and select "Stop Provider->Web Shield."
2. When you are prompted to save your changes to the resident task so they are persisted through restarts, select "yes."
Hope this helps.
***edited to add...***
I re-read your original post. You mentioned not being able to use the On-Access Scanner. If you can't get to the option to stop the Web Shield in the On-Access Scanner, you could run the installer again and change the installation option to remove the Web Shield. -OR just uninstall avast! and then reinstall it making sure to choose the custom set-up and then remove the option to install the Web Shield.

I started having a similar problem a couple of weeks ago, but only when I was running Apache Server.
I had been using Avast for over a year with no similar problem.
I assume a program update may have been the cause.
Turning off the WebShield eliminated the problem.
Exploring further, I changed the port number for HTTP redirects to blank under Web Shield, Customize, Basic Settings.
This is a setting for transparent web scanning.
IE and FireFox Browsers now work correctly with Web Shield enabled.
-

This sounds more like a firewall (which is it ?) blocking ashWebSv.exe after a program update this process will have changed, your firewall should have asked permission and you probably denied it.

This is a setting for transparent web scanning.
IE and FireFox Browsers now work correctly with Web Shield enabled.
1. That effectively disables the web shield provider as it isn't redirecting anything, the default is 80 and is correct for both transparent or manual set-up to use the web shield.
2. They work only because you have stopped web shield redirecting http traffic. If you check the web shield provider details you will see that content isn't being scanned.
Solution, replace the deleted port 80 and ensure your firewall alows ashWebSv.exe.
-
I think you missed this line.
but only when I was running Apache Server.
The problem has nothing to do with the firewall as all works well as long as Apache Server is "OFF".
Apache is set to listen to 8080 requests from 127.0.0.1(localhost). I don't understand why it would cause a problem with Avast now, as it never did before.
I set Web Shield to 81 and there are no browser problems now with Apache running. Interesting.
Thanks
-
I did see it, but I wasn't sure if this was simply you connecting to a server, rather than trying to run avast on a server.
I don't know how avast would react when you are running a server since avast home/pro isn't a server AV solution.
So sorry if I got that wrong, you will have to hope someone with some server experience picks this up.
-
Jenstar:
Thanks for the nudge there! I was looking at that "provider" but it did not say "web shield", soooo, rather than mess up I just stopped the avast running progs, beeeing--they sometimes cause my win98 to connect very slow.
I may have unknowingly mislead you by my lack of proper terminology. I could not run the avast running program feature(s), being they were not running after I eliminated them by doing the msconfig routine.
I am about to recheck them and then try to eliminate the web shield. What does this web shield "shied" anyway? From reading the forums it is not a firewall--so what is it?
Thanks, Diligent
-
A good place to start would be the avast help file Resident Protection, Web Shield Provider.
Web Shield provider protects your computer from viruses that may infect your computer when browsing the Internet - especially when downloading files from web pages.
If you - possibly by mistake - download an infected file and try to start it, avast! will prevent the infection thanks to its Standard Shield provider (which scans all files that you start of open). With Web Shield, however, the virus will be detected even sooner - during the download of the file. So, Web Shield makes your computer even safer than before.
This provider also makes it possible to block specific URL addresses.
So it monitors your web browsing for possible infection blocking it before it has a chance to get on your system. With win98, this isn't transparent and you have to have set-up your browser/s to use the web shield proxy. If you didn't do that then it couldn't slow your browsing, however, I see no noticeable slowdown and I use a dial-up connection.
For IE - broadband users: - Tutorial - Web Shield Proxy Set-up for IE (http://www.avast.com/files/tutorials/ws_ieproxy.htm)
For IE - dialup users - Tutorial - Web Shield Proxy Set-up for IE (Dial-up) (http://www.avast.com/files/tutorials/ws_ieproxy_dialup.htm)

Thats helpful Dave. Appreciate it. I will study that. Like you say, there should be no slow down.
The slow down, that is mostly the connection, is only manageable (so far as I know) by eliminating running programs, besides the normal Win98 and general malware-virus clean up procedures.
Once that is done, the connection time is reasonable. The temporary internet file collects cookies and giff's etc. for quick access, so the download image and picture time is reduced a bunch. Otherwise, both the connection and these picture-image download take until doomsday to connect and download.
Is that normal with a win98?? I know dial up is slower than DSL and other cable methods, and can see what the normal speed is, I think, but having to go through all these clean-up progs and etc. just to gain a reasonable connection and download speed just does not seem right somehow. I should be able to keep the avast progs running for protection and still connect and downlaod within a reasonable time.
Is there an avast tutorial or help file on this subject similar to the web shield one that you provided that I can read?
Again, thanks for the web shield info. I will study that.
Diligent.
-
I can't say what is normal for win98, I haven't used it in years but the connection speed shouldn't be dependant on your OS. My dial-up connection speed has pretty much remained stable with different OSes. What effects connection speed is the condition of the telephone line (old copper cable, noise on the line degrades connection speed) and the physical length of cable to the telephone exchange.
I usually connect at 49.2 Kbps or 50.6 Kbps since a dial-up modem theoretical maximum is 56.0 Kbps (and some times considerably less) you can see the degradation. I live 9 KM from the telephone exchange. Here in the UK there are some who live in areas where there is a limited number of lines available your line could be split (called DAX-ed here) so it is shared with another number, this is a massive drop to a max of about 33.6 Kbps and with degradation much less.
Connection speed also doesn't directly equate to download speed I have seen times when I get a good connection speed and zilch poor download speed and vice versa at times.
The tutorials have been created to cover commonly asked questions or problem areas and they don't extend to an avast tutorial. The avast help file really is the only guide documentation.
-
hello,
I've the same problem since the last update.
I've read all the thread and make each modification but nothing new, i can't surf the web with the web shield activate.
i I've another strange thing, my ashserv is really heavy in CPU time, that make my PC really slow when it doesn't reboot. any move make something like 20seconds for execute.
that make 2 weeks my avast is strange, resource eater, web blocker...
I'm using avast for 2 years without problems but now, look like it's the end...

Sorry but I don't think this is the same problem if you have tried the things in this topic and that hasn't worked.
Rather than say you have tried everything, please tell exactly what you have tried ?
Also let us know a little about your system, Operating system, browser, firewall, other security programs, etc.
-
OK,
system : xp home sp2
no firewall
one router (nothing change before and after the problem)
browser : IE7 and FireFox 2.x
other security soft : windows defender
other scan : scanned yesterday with avg up to date
scan with windows defender in progress
already tried : the .ini story, clearing logs, proxy configuring
------------------------EDIT--------------------------
I've just finish the re-installation of avast, same problem, the windows defender is finish, nothing new.
-----------------------EDIT 2-------------------------
http://luzftp.free.fr/gest/vracimg/problemeavast.jpg
here, a screenshot of the process, the white back, it's firefox who haven't enough resource for displaying this page and the frame, it's a menu who take 30second to draw.
has you can see, ashserv is really CPU time eater but it's another problem...
-
Do you also have AVG antivirus installed on this system ?
Having two resident scanners installed is not recommended as rather than provide twice the protection it can cause conflicts that could leave you more vulnerable.
The high CPU could be multiple scanning and possible conflict with another AV.
-
i know that !
they weren't installed at the same time.
and when i took the screenshot, there is not any files left from avg.
-
If the CPU remains high for a long period, is the avast icon rotating ?
If not there is obviously something causing it to hang. In the past one of the options that seemed effective was a reinstall, uninstall, reboot, install, reboot.
It would probably be best to download the latest version of avast and save it to your HDD, somewhere you can find it again. Use that when you reinstall.
-
the avast's icon doesn't rotate.
i have already uninstall, reboot, install a fresh version up to date, reboot and hang after some thing like 3 minutes after the complete start of the PC.
-
I'm at a loss as to what else to suggest, has anything else on your system changed recently, windows defender updates, etc. ?
Try disabling windows defender and see if that has any impact.
You say the problem occurred after the last update, "I've the same problem since the last update." There hasn't been a program update for some time, 4.7.942 was released on January 15, 2007 so is it about one month ago this started to happen ?
The reason I say this is that the VPS updates shouldn't have any effect on the program as no program files are changed.
What is the sensitivity setting on Standard Shield, Normal (default), High or Custom ?
-
ha, sorry, the story of the last update is for the white page in browser, it's like at 14h15 it work and 5 minutes later, white page of the death.
for the second problem (hang), windows defender isn't activate by default, i activate it when i need it. one scan each week in general. I take note of the problem 2week ago with the start of my holiday, before, i have really use mu PC then...
-
I can't understand why this could be happening, the VPS updates don't change anything and you didn't say if it was a Program update (usually requires a reboot) or VPS update. There should be no difference in how avast's web shield works from one browser to another it just monitors http traffic, so I'm at a loss as I don't have IE7 or Vista and cant test anything.
Sorry we will have to see if one of the Alwil team or someone with vista and IE7 picks up on this.
-
it's IE7 for Win XP and i really don't catch a thing either...
-
Hello,
Somebody solved this problem? I have the same:( I have just reinstalled windows xp and then I installed Avast but I cannot work with any web browser :( I set access in the windows firewall and even put localhost with port 12080 how they wrote on the website Avest but it doesn't work:( I am waiting for any help...
-
Hi,
I had the same problem, Web Shield block my web (http) access,
It start after I had applied the following tweak (for improve XP performance) :
Start regedit and navigate to the following key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Session Manager\Memory Management]
Add these two lines then save the changes and reboot:
"DisablePagingExecutive"=dword:00000001
"LargeSystemCache"=dword:00000001
(I take the instraction from - http://kadaitcha.cx/performance.html )
After I restore the original values ( dword:00000000 ) for the both registry lines, all came back to work fine !!!
I don't really know why it happen in my machine, because in my friend it work fine, maybe it related to some new hotfix from microsoft ????
My machine : Windows XP SP2 (with all updates), IE 7

I did some more checking, and the problem is coming from "LargeSystemCache" registry changing.
Anyway, when I searched the web, I crossed a lot of different opinions, about this tweak.
Here is some that catch my mind:
http://www.tweakhound.com/xp/xptweaks/supertweaks11.htm
http://qaix.com/hardware/266-770-xp-s-largesystemcache-can-cause-data-corruption-read.shtml
http://www.hardforum.com/archive/index.php/t-716644.html
so, as I understand it, this strange behavior, is related to the hardware (it explain why on my friend computer it work fine !!!).
I have Ati video card, 1 GB RAM, 160 GB HD, AMD Athlon 64 X2.
Hope this information will help other.

I've been having the same problem for 2 weeks now. Can't browse internet when on-access protetcion is running. I've tried things mentioned here with no help. I'm using win XP, Opera and Kerio firewall.
If I keep on-access protection running I can usually see the internet page if refresh the page a couple of times. Sometimes the page is loaded with no problems.
-

What happens if you disable WebShield?
Into the firewall settings, the following programs should be allowed to connect:
C:\Program Files\Alwil Software\Avast4\ashWebSv.exe (avast! Web Scanner)
C:\Program Files\Alwil Software\Avast4\ashMaiSv.exe (avast! e-Mail Scanner Service)
C:\Program Files\Alwil Software\Avast4\Setup\avast.setup (avast! Update executable). This is a temporary file that just appears when an update (check) is about to launch, and disappears again afterwards.
If I keep on-access protection running I can usually see the internet page if refresh the page a couple of times. Sometimes the page is loaded with no problems.
I think this could be related to Kerio privacy features + avast. If you disable that part of Kerio, will it help?
-
Ok.
I checked that ashWebSv.exe, ashMaiSv.exe, avast.setup and others Avast related files are not blocked by the firewall. The same problem remains still. I tried different kerio settings with no help. Even shutting down the firewall doesn't help.
Disabling webshield didn't help either.
..but then I uninstalled my Finnish version of Avast and installed an English version. The English version allows me to browse internet by shutting down WebShield instead of shutting down on-access protection.
So the problem is partially solved, but this is still a mystery to me. Everything was working just fine before, then I went to a vacation and didn't touch my computer for a week. And when I got back home I had this problem. Very strange. All I can think of that something has updated itself and caused this somehow.
-
So the problem is partially solved, but this is still a mystery to me.
Can you post the full path where you were installing avast?
-

I installed it to D:\Programs\Avast (Windows is in C: drive)
Does it matter where it is installed?
-
Normally it doesn't matter where you install it, however with some foreign (sorry) language version it is possible that your version of windows also uses special characters (accents, etc.) in the path to avast, that has in the past caused a problem for some avast users. They have found it OK when installed to the default location or some like you have installed the English version. Why that would resolve what might be the special character accents is beyond me.
-

David answered.
To check your installation, please, post the last 100-200 lines of avast log: C:\Program Files\Alwil Software\Avast4\DATA\log\Setup.log

Setup.log
Didn't count them, but hope there are enough...

For any reason, avast cannot access that folder correctly.
I suggest an installation from the scratch:
1. Uninstall avast from Control Panel first.
2. Boot.
3. Use Avast Uninstall (http://www.avast.com/eng/avast-uninstall-utility.html) for complete uninstallation.
4. Boot.
5. Install again the last version.
6. Boot.
7. Check and post the results.

Sorry, the thread is too long to search it now...
Which is your firewall?
Into the firewall settings, the following programs should be allowed to connect:
C:\Program Files\Alwil Software\Avast4\ashWebSv.exe (avast! Web Scanner)
C:\Program Files\Alwil Software\Avast4\ashMaiSv.exe (avast! e-Mail Scanner Service)
C:\Program Files\Alwil Software\Avast4\Setup\avast.setup (avast! Update executable). This is a temporary file that just appears when an update (check) is about to launch, and disappears again afterwards.
Don't need rights to connect:
C:\Program Files\Alwil Software\Avast4\ashServ.exe (avast! antivirus service)
C:\Program Files\Alwil Software\Avast4\aswUpdSv.exe (avast! Update Service)
Maybe you can remove the avast entries and let the firewall ask for permission again...
-
I made sure that my Kerio firewall doesn't block any avast related files. I cannot browse web without shutting down web-shield even if I have the fire wall disabled.
what about these parts from setup.log? They seem to relate to install time. I configured the firewall not to block avast files and then rebooted. There were no such entries matching the re-boot time. Can these be the issue? Should re-install avast one more time with firewall disabled?

What if you try disabling the transparent proxy and manually set your browser/s to use the web shield proxy.
How to disable transparent web shield proxy and allow only those browsers you want use it:
In avast! go to Web Shield provider, Customize..., Basic tab, blank the redirected HTTP port field (remove the 80). Now no browser can use web shield unless you manually configure it to use Web Shield.

I don't believe the fix security on those folders would have this impact, that may be setting folder permissions, etc. though I don't know for sure.

Hi, I just wanted to pipe in here to share my experience with this problem.
Ever since two days ago after my pc locked up and I had to bring it down hard, I've had the same problem described in this thread. I've tried just about every suggestion to no avail. Somehow I stumbled across a corrupted folder C:\windows\temp\_avast4_ I removed this folder and my problem has gone away! Avast is working perfectly now!! I'm hoping that his might help some of you having similar problems.

I have to thank you to have posting there... a solution that we haven't addressed.
I'll keep it in mind when there were connection troubles.
