Title: Strange problem with Internet Explorer
Post by: reptin on March 21, 2005, 05:13:32 AM
Yesterday morning, i started up the computer and attempted to access the internet VIA Internet Explorer. It wouldn't load, even though my internet connection was working *other things such as messenger services would connect* I called my ISP, and explained the problem to them, and they told me they thought that my IE was corrupt, so i had to use the address bar in places such as "my documents" etc. to access the internet. My internet explorer is working now, but only since i disabled the web scanner in Avast. I'm using the most recent version of it, and i've never had any problems with it before. Any advice??

Here the same problem. Since the newest version of Avast. I can't acces sites via internet explorer. I also called with my ISP and there are no line problems. When I disable all the services of Avast everything is fine. Windows XP professional servicepack 2 with the latest updates. Avast v 4.6.623 vps: 0511-1.
Before I didn't have any problems. I didn't change anything. I didn't installed any new programs either. Weird.
Anyone?

Update: I disabled the Webshield, now 5 of the 7 services are on. Now I can use Internet explorer again. So it seems that there is a problem with the webshield service?

I'm having a similar problem- IE6 will start, run fine for a while, then hang while trying to load a page.  No error message, just browser window goes blank and it sits there looking as if it's loading page but not actually doing anything.  The really odd thing is that if you then look at the view menu, the "configuration" option has been replaced by a "text labels" option.  The only way to get the internet back up and running is to restart computer.

I've tried installing firefox 1.01 and this does the same thing (minus the text labels thing).  Anyone know what's going on?

If you configure the proxy server into IE options to 127.0.0.1 and port 12080, will it work?

To change the proxy:
Internet Explorer: Tools > Internet Options > Connections > Lan Settings > Uncheck 'Use a proxy server'
Firefox: Tools > Options > General > Connections Settings > Check' Direct connection to the Internet'

I tried both: 1. proxyserver checked and address 127.0.0.1 and port 12080 and webshield on. 2. proxyserver unchecked and webshield on. Neither of these settings does work. Only when I disable the webshield in Avast I can use internet explorer. When I use file explorer and type internet addresses manualy it is working with webshield on.
So it seems to me that there is a problem with the webshield and not a problem with the settings. Before the last upgrade there was no problem at all.

Every time I access the internet where Avast runing in background, I get a Avast warning for finding a virus with file name: (http://home.earthlink.net:80/~hvtopiwala/loudcash.exe). I can not find that file in my computer.
Can any one explain that!

KRA, avast! is telling you that the file you are trying to download from home.earthlink.net named loudcash.exe is a virus.  It is not on your computer because avast! Webshield is preventing the virus from being downloaded.  You should get a message in the popup warning telling you to abort the connection.
Title: Re: Strange problem with Internet Explorer
Post by: sded on March 21, 2005, 10:44:29 PM
For the IE problems:
1) What firewall are you using, and have you given webshield permission to access the internet?
2)Under webshield setup: basic-Web scanning, intelligent stream scanning checked, port 80 redirected, ignore local comms unchecked
advanced-show detailed info to see what is happening
3) Are you running XP (SP2?)
4) Are you using any other mail proxies for spam or ?
5) In IE, connections/lan settings proxy unchecked
6) Does the avast! log viewer indicate a problem?
7) Could you start your own threads to make it easier to help with the individual problems?

If web shield gave the warning it would also give the option to abort the connection (e.g. stop downloading the page or file), was it this or the Standard Shield warning which would give more options because it is on your HDD. If it was web shield and you aborted the connection, then you won't find it on your HDD, it wasn't downloaded.

Can you edit your links so they aren't active, so no one can stumble on to it either out of curiosity or accident, just put spaces on either side of the :// as I have done in the quoted text.

1. Windows XP firewall: Yes Avast has the permission to access the internet
2. I tried those settings now: but still the same problem
3. Yes (I already gave the specs in my post)
4. No
5. Yes
6. No
7. The problem is similar to the post of "reptic" and "casinosoul" (Casinosoul gave the exact description to what is happening) So I think this is the right thread to post.

Only when I disable Webshield I have a normal working internet explorer and normal access to the internet. With the former version of Avast there was no problem with the webshield enabled! ;)
In the past (I'm using this program for more than 2 years now without any problem) I didn't have to change settings to make the program work. So I still think there is a problem with the program not with my settings. And I don't want to change settings to make the program work. That's for experts and I'm not........................

FransH, are there specific sites you can't access?  If so, a few example URLs?
https redirected to port 80 or similar?  Or you can't access the internet at all?
Title: Re: Strange problem with Internet Explorer
Post by: FransH on March 22, 2005, 12:27:28 AM
My homepage does start, but other sites are impossible to access.

But this answer from Techie 101 in the thread of Bert Turner: "Must disable Avast to browse.. Oh man." explains enough to me :) I'm confident waiting for the next update, until then I disable Webshield service.

Techie101: My goodness!  Web Shield has caused a rain of terror upon us! 

Ok, general information.  The Web Shield is activated upon boot by default. If you turn it off, using the TERMINATE button, it will not enable by a merely starting the OAP module.  You will need to go into the WS module and use the Continue command.

The Web Shield for some reason unclear right now "filters" too good!  Some sites appear to it as "suspicious or dangerous" and it will not let them pass.  This can be remedied by adding them to the Exceptions list within The WS module under Customize, or try disabling the "Intelligent Stream scanning" function under the Basic tab.

 Zone Alarm has a separate problem because it interacts with Port 80.  Search the forum for the solution.

You do not need to disable the entire Avast Resident Scanner if you are having surfing difficulty.
Just disable the Web Shield until the issue/s can be resolved.
Why remove ALL protection when only a small "limitation" is necessary.

The Web Shield is an excellent new feature but with all new things comes some "bugs" which everyone here and the Avast Team are working to resolve (as always.  )

Good luck.

Post by: sded on March 22, 2005, 12:37:15 AM
Just trying to localize the problem to see if anyone can help.  I am running XP SP2 on 3 different  machines with latest avast!, using browsers Opera, IE, Maxthon, Avant, Netscape and Firefox with no such problems; firewalls KPF, SPF, ZAF (SP1).  So suspect one of your installed programs or its configuration is incompatible with the .623 upgrade.  But if you are using no other proxies, and only XP firewall, then ?  Have you tried the other suggestion of blanking the redirect port in webshield and setting up the proxy in your browser (for http only) to 127.0.0.1 port 12080?  And you are not running a VPN?
Title: Re: Strange problem with Internet Explorer
Post by: punkybouy on March 22, 2005, 12:47:40 AM
I too have the same problem ever since the program was automatically updated last week to the new version 4.6.623.  If I stop Web Shield everything is fine.  Not only that I can " restart" the module after 20 minutes and while is still indicates it is waiting for a subsystem to start I can surf just fine.  I just tried disabling Zone Alarm but still can't get Web Shield to run without indicating it is waiting for a subsytem to start.  For the record I am running XP with SP2 750 MB RAM.
If Web Shield is a new feature I'll just disable it for now.  I have used Avast for 2 years and think its a great product.

Same problem started occurring for me yesterday. Couldn't browse anything either with IE or Firefox. Uninstalled avast and everything became fine again. Downloaded and installed the newest version of avast. Everything good now. Fingers crossed.
Title: Re: Strange problem with Internet Explorer
Post by: xzot on March 22, 2005, 04:09:48 AM
Yep, me to.  I have been experiencing problems for several days.  I realised that it was IE related when Navigator worked fine.  If I stop the webshield, no problems.  I have been following the various threads about probs with webshield and have tried the suggested 'fixes' but the only way for me to browse with IE is if webshield is stopped.
I am running W2K(sp4), IE6(sp1), Kerio Persional Firewall & Spybot.
Title: Re: Strange problem with Internet Explorer
Post by: paulorox on March 22, 2005, 08:59:12 AM
I am also experiencing this problem. It only seems to be with Web browsers - it happens with both IE and Firefox.

I can normally browse for around 20 mins after turning the PC on or rebooting before the problem occurs.

I can use the ping and tracert command prompt fine. Sometime I can browse to https sites ok but at others even they fail.

MSN and email all work fine.

Hi

Just joined to say I have this problem too.

Since discovering that avast was the problem (and not firewall, connection, etc.) and looking here, I have tried stopping and restarting Webshield and access to webpages is restored.

How did you discover this? If you only stopped web shield, then you have yet to positively identify the cause.

Yes, stopping web shield will seem to resolve the problem, however, is the firewall refusing access to the ashWebSv.exe (web shield) if so then web shield can't work.

You need to identify the exact cause of the problem, web shield, firewall or do you need to set-up the proxy manually if you are using win98.
Title: Re: Strange problem with Internet Explorer
Post by: onzey on March 23, 2005, 04:28:08 PM
I had tried exiting my firewall or setting it to "Allow all" and that did not help.   Then found this thread where people were having the same problem and started to look at avast.

(ashWebSv.exe is set to "Allow" in my firewall application).

Post by: rika on March 23, 2005, 04:54:56 PM
 I downloaded Free Avast 4.6 a couple of days ago, and immediately began to have problems. First with ZoneAlarm - which blocked Internet access completely. (Closing down ZA everything would work just fine, but of course this was not a safe option..)

I uninstalled ZoneAlarm and re-installed it but the problem persisted. Now yesterday, everything seemed to work at first, (the system had slowed down considerably, though) but then the system slowed down, and finally both IE and Firefox flipped, and trying to close down the computer everything just paralized.

 I also get this short error notice (which I hardly have time to read ) when closing the computer, saying that "there is an error in the memory XXXXXXX that refers to XXXXXXXX...memory can't be "written""

And everything worked just fine before I installed avast.

I'll probably get rid of this avast if I don't find a solution soon-...

What are your system spec's ? Avast! & ZoneAlarm are working fine together for many, got to be some other conflict......

Sorry Technical I'm still here.  Haven't posted as I have nothing new to add.  I have been reading various threads about this issue and have been waiting for a either a new realease or a fix of our problem.  I believe webshield is the problem as I can browse fine with navigator but not with IE.  Stop the webshield and I have no problems.

No, it's my fault... Sometimes I get impatient and bitter.
This problem, for me, is related to the firewall (or even a local proxy) and avast WebShield.
Anyway, I'm not in conditions to debbug it...
Keep tuned and let's see if we succeed on troubleshooting it.
Title: Re: Strange problem with Internet Explorer
Post by: rika on March 23, 2005, 10:44:54 PM
 Same here. I am currently without webshield. With the webshield on, I am no longer able to access Internet, mainly because Zone Alarm blocks the Internet access.
Yet even now the whole system is running slow. And again, these problems did not exist before I installed Avast. 
The system I have on my laptop:
 
     XP Home Edition (SP1)
     
     518Mhz  192 Mt Ram

 Avast Home edition, version Mar 2005 4.6.623       updated 22.3.  0512-0

 Zone Alarm version 5.5.062.011


 Don't want to give up yet since I've heard so many positive comments about Avast, even though it's been a rough start...

I already stated earlier in this thread. That before the last update there was no problem with Avast or the webshield service. I was running Avast with the webshield on. I'm running Windows XP prof servicepack2 with the latest updates. I'm not running a firewall other than provided by Windows XP. All in the default settings. I didn't change anything last weeks in my settings (only tried some settings suggested in this and other threads), neither installed new programs.
Last week there was a update from Avast. As usual I installed that update. After that I got problems with IE accessing the internet.
First I didn't think it was Avast. I checked the line with my provider. Then I discovered that after the update of Avast, when I disabled the webshieldservice, I can access the internet without any problem. When I switch webshield on the same problem as described earlier in this and other threads occur to me.
Also in another thread a certain techie101 acknowledged that there is a problem with the webshield (he is an evangelist and who would not believe an evangelist? ;) and the Avast team is working on it. So maybe a suggestion: bring the webshield back in the state as it was before the last update or disable this service temporarely. And another suggestion: Make a sticky about the problem with the webshield and state that the Avast team is working on it. Then we all shall wait in confidence for the next update.
But maybe I'm too simple and logical?....................................

Same here. I am currently without webshield. With the webshield on, I am no longer able to access Internet, mainly because Zone Alarm blocks the Internet access.

Well, if Zone Alarm is blocking it then the obvious solution is to unblock Web Shield (process ashWebSv.exe) in your firewall configuration. Does it makes any difference?

Sorry, I don't mean to be rude, but no application should be accessing the internet unless it is allowed in the firewall. That's after all the reason why you installed the whole Zone Alarm thing, isn't it?

I disabled web shield for several days.  What the heck the message said it was waiting anyway for something or other to start.   Without it I was able to surf just fine.  Tonight after being on the computer for several hours I went in and re-enabled it.  The provider started right up and it is working just fine and not waiting for anything to start.  Still think the problem is with the provider. Maybe Zone Alarm is preventing the provider/service from starting as quickly as it should?

Hello Lukas, and thank you for your help!

But this was my problem, the configuration of ZA wouldn't help.
"process ashWebSv.exe" was infact unblocked in ZoneAlarm, so it should have been able to work. The weird thing was that even though I gave these programs the permission to access the internet, once they did, ZA blocked all internet access from my computer, not only that program.

 At times, ZA announced to have blocked Internet access immediately after start-up. I don't know if this had something to do with the fact that Avast starts up before ZA...just a wild guess.

The good news is that for one reason or another, everything seems to be working ok now!

(And sorry for the bothering, I AM a real newbie in these matters, so it might have just as well a problem with something I did, but surprisingly many people were having the similar problems with the new updated version...)

At least I got to test this Support Forum, which is a great support, by the way, I'm learning new things all the time!  :)

Title: Problem solved: AVAST Internet Explorer Windows Firewall
Post by: REDACTED on June 10, 2006, 01:12:27 PM
Hi guys,
I just got the same problem but found its origin and a solution.
my recent problem is as for you: no more internet access via internet explorer, except when I disable the web shield of AVAST.   ???

I found that it is not caused by AVAST update:   :o
- same problem with an older AVAST version that worked previously on my PC
- no problem with the latest AVAST  on another PC

the difference between the 2 PC is just that I recently updated windows XP on line on the PC that has now the problem.
when I disable the (updated by Windows) Windows Firewall and leave AVAST Web Shield operational the result is....Internet access is working back OK !  ::)

Conclusion: the Windows Firewall updated by Win XP update online is blocking internet acess when AVAST Web Shield is running !!      :)

Now here is the solution:
Open Windows Security Center
click on Windows Firewall
click on the EXCEPTION tab
click on ADD PROGRAMS
select AVAST
valid with OK
valid the Windows Firewall with OK
and that's it: now Windows Firewall is no more blocking internet connection with AVAST running.

 :D

Thanks a lot to all of you guys: your exchange of info on this forum helped me a lot to analyse and fixed this problem.
I hope that it can be helpful to other too....


 ;)

I had the same problem, no Internet surfing. Had email though. I have kerio firewall & left the block everything rule open. Found that Avast web scanner needed UDP rule(both directions) to function. Now I have web surfing ability back as normal. Don't understand why I had to add a UDP rule though. My local IP is the only one accessing this rule.
Title: Re: Strange problem with Internet Explorer
Post by: bearmstead on June 10, 2006, 07:51:00 PM
I log the block outgoing rule & found that I also needed to add "allow UDP outgoing" to email scanner rule. Already have had the allow incoming UDP rule. Don't know if this behavior is due to Avast or my local IP. My local IP is the one that requested UDP out.
Title: Re: Strange problem with Internet Explorer
Post by: lukor on June 22, 2006, 07:39:22 PM
The UDP traffic is probably due to name resolution (DNS) that both services perform during their operation.

Hi, I haven't any problems way down too but, why don't you update avast! to latest version [4.7.844] ? Maybe issues can be resolved that way.

Buena suerte!
