I have a problem with webshield in that it stops some web pages loading after the initial header. Details are:
On the popup webshield just displays the main web address but then ceases to load the remainder of the page. For example when I go to www.betanews.com the popup shows scanning www.betanews. com and the fails to download anything else.
This problem only appears on a few web pages some of the others are pcpitstop.com, download.com, yet there is no problem with grc.com, gateworld.net or majorgeeks.com the popup shows elements loading, although according to firefox the page does not completly load 'cos the little whirly thing at the top of the page continues to rotate although the page appears complete.
Thanks for your help in this problem it's greatly appreciated.
WinXPsp2 Zonealarm Pro Spywareblaster Spyware Guard IE6 and Firefox. All up to date. DSL connection no proxy.

Interesting, this seems to be the same problem as discussed here: http://forum.avast.com/index.php?topic=11336.0
essexboy, could you try IE and confirm that the web pages in question display correctly in this browser (as BigMur reported)?
Thanks
Vlk

Displaying fine with XP Pro SP2, firefox and outpost pro
-
Have just tried on IE and BTYahoo browser. IE gave a server not found page, however BTYahoo had no problems at all yet I use the same settings for all browsers.....
-
Server not found? Wasn't the message red? That would be a WebShield's message then. Could you quote it precisely?
Thanks Vlk

No it was the standard IE page
Please try the following:
Click the Refresh button, or try again later.
If you typed the page address in the Address bar, make sure that it is spelled correctly.
To check your connection settings, click the Tools menu, and then click Internet Options. On the Connections tab, click Settings. The settings should match those provided by your local area network (LAN) administrator or Internet service provider (ISP).
See if your Internet connection settings are being detected. You can set Microsoft Windows to examine your network and automatically discover network connection settings (if your network administrator has enabled this setting).
Click the Tools menu, and then click Internet Options.
On the Connections tab, click LAN Settings.
Select Automatically detect settings, and then click OK.
Some sites require 128-bit connection security. Click the Help menu and then click About Internet Explorer to determine what strength security you have installed.
If you are trying to reach a secure site, make sure your Security settings can support it. Click the Tools menu, and then click Internet Options. On the Advanced tab, scroll to the Security section and check settings for SSL 2.0, SSL 3.0, TLS 1.0, PCT 1.0.
Click the Back button to try another link.
Cannot find server or DNS Error
Internet Explorer

So IE cannot even query DNS for this host? Interesting... Are you using a software firewall? If so, which one? Can it be that it's blocking some of your traffic?
Thanks

Yes Zone alarm Pro. No I don't think so 'cos if I turn off webshield it loads no problem..
-
Little PS I just tried the pages BigMur is having problems with Guess what so am I
-
And both of you are using ZA... :-\
What exact version of ZA do you have?
-
5.5.062.011 the latest version
Webscanner has full access and server rights
EDIT same as BigMur
-
We'll retest in our lab and will let you guys know.
I'm sure we have tested with ZA but probably not this version (it was released 10 days ago).
thanks

Ta Vlk thanks for your help.. ;D

i have a similar problem..
winXP pro SP2, Firefox 1.0 , thunderbird 1.0 , DSL connection through a router.. no proxy
everything updated.. once i updated avast last night i noticed that the webshield and webmail shield block me from browsing ANY pages in IE or firefox and i can't check my mail unless i switch off webshield and internet mail...
are there alot of people with this problem?
example of IE error text;
"HTTP 504 - Gateway timeout
avast! Web Proxy
--------------------------------------------------------------------------------
When the server, while acting as a gateway or proxy, contacted the upstream content server, it did not receive a timely response.
GET http://www.google.co.uk/
"
and firefox is much the same.
confusing hm ?
-
That "Gateway timeout" was exactly the same error I got before I found that ZA hadn't given the Web shield access rights. Probably because its request to do so got buried under something else on-screen.
Check the Programs-permissions page in ZA, you can change the permission status manually there (click on the "X" or whatever and then choose to permit it).
-
I know this isn't entirely relevant at this point, but I'd like to mention that I'm having no problems with Avast 4.6 and the latest version of Kerio Personal Firewall, and I've used both Firefox 1.0 (my main browser) and the most updated version of IE. Operating system is a fully patched Win XP Home.
-
On the popup webshield just displays the main web address but then ceases to load the remainder of the page. For example when I go to www.betanews.com the popup shows scanning www.betanews. com and the fails to download anything else.
What popup are you talking about? I don't get popups when I use Web Shield unless a virus is found.
-
He was refering to a popup from a firewall, asking for permissions for ashWebSv.exe...
Unfortunately, we're bemused to find that a number of renowed firewalls somehow don't work correctly - simply fail to ask and deny all network access for this process. While this is not really an avast problem, we understand that average users won't understand what's going on and simply feel that "avast is blocking access to the Internet". We've spent a lot of time testing webshield with all major firewalls - and yet it seems that on some machines, it still doesn't work correctly.
beebot, you didn't quote the Gateway Timeout message in its entirety ;) There's a paragraph about the possibility that this is caused by a firewall blocking access to ashWebSv.exe. I think this is the case here.
Thanks
Vlk
-
well, i thought it might be zone alarm too, so I checked the permissions and fixed it. I still get the same problems for some reason.
Even with zonealarm disabled i get this gateway error. So right now if i want to browse i have to switch off webshield, same goes for if i want to check mail. This kind of defies the point of having avast running at all ;D... Its just wierd because i really cant see why its coming up with any error ???. I have been running avast for over a year now with no problems so far until i updated last night.
hmm i'll let avast run some checks to see if i have any horrible nasties on this pc anyway and check back later. cheers for the help guys ;D
-
nevermind! i managed to fix it :-X and yes it was a bug with my zonealarm install. for some reason it only seemed to take notice of the new permissions for ashserve.exe after i did a restart >:(
any other free firewalls out there that are recommended?
sorry if that got a little confusing there and thanks again
-
OK, I retested it on a test machine:
XP SP2 + all critical updates
avast 4.6.603
ZA 5.5.062.011
Firefox 1.0
Unfortunately (or not?), the problem does not reproduce here. All of the above mentioned sites (www.avast.com, www.microsoft.com, www.bbc.co.uk) load nicely in Firefox... :-\
-
Hi Vlk back again. I had an old version of ZAPro on my drive so I uninstalled the new and installed the old 5.5.062.004 . The popup I was talking about was the Avast on access scanner message (I have set webshield to show detailed info on performed action). I am still having the same problem so I'm wondering if it is something machine specific. I disabled Spyware Guard, Spyware Blaster and Microsoft Antispy with no change. What I intend to do next is download the latest Avast to disc then uninstall ZAPro and Avast then reinstall the latest version of ZAPro followed by a clean install of Avast. I'll be back in a bit to let you know how it goes.. ;D ;D
-
Hi Vlk back again....... ;D ;D ;D ;D ;D ;D..... it worked a total uninstall of ZAPro and Avast clear up the registry reinstall fresh and voila no problems (fingers crossed). Could it be something to do with installing 2 updates so close together ????
-
Hmm, I have absolutely no idea what was causing the problem... :-\
-
Well I would say this is definitely a problem with the avast update. Since the update I hadn't restarted my computer for around 20-24 hrs. Everything had been working fine. Then I restarted my computer and couldn't get out to my router even. I turned avast off viola! I had access. I restarted again with the same result, getting the error message shown below. I turned off webshield with no success, I then turned of the neywork shield and my internet worked. I am only running the Windows XP Pro Firewall and i'm sure it never popped up anything saying something needed access. So I am assuming I need to go in and manually allow Avast Internet Access. I also noticed that the web is running noticeably slower than before I rebooted. Will post back with any new findings.
The page cannot be displayed

HTTP 504 - Gateway timeout

--------------------------------------------------------------------------------
When the server, while acting as a gateway or proxy, contacted the upstream content server, it did not receive a timely response.
Too many open sockets.
\Device\HarddiskVolume1\WINDOW\system32\opsq.exe
adding Avast for Access in Windows Firewall Didn't work by the way
-
OK I reproduced the problem. Normally I have the privacy settings on ZAPro set at high for cookie control and ad blocking. I didn't reset them after the clean install untill about 10 seconds ago and when I did guess what, I couldn't get onto the sites again. Reset privacy to medium no problems. So it appears to be a ZA fault when ad blocking is set on high it blocks the site cookie settings appear to have no detrimental affect.
-
I've only just started having problems with the Gateway Timeout messages. ??? I don't have a software firewall on my computer because my router has a built-in firewall.
-
You can add another 2 people to the list of those having problems with Avast following the recent update. My Girlfriend and I both did the update within minutes of each other, she had trouble getting on some sites I could get on, and I had trouble getting on some sites she could get on. I use ZoneAlarm, she uses Nortons, she's on dial-up, I'm on Broadband. The only obvious similarity was us both doing the Avast update. People can continue to bury thier head in the sand and blame it on conflicts with other software, but the fact is, these conflicts never existed before the update, so it IS a problem with their product. I was a very happy Avast user up till now, and I hope they stop pointing the finger elsewhere and fix whatever it is THEY got wrong as they have a very good product (or had till now)
Also meant to add that we also had problems loading Yahoo Messenger while Avast was running, the only way to get it to open was to disable all On-Acces Protection, funnily enough, doing that fixes the browsing issues aswell.
-
Pity guys that you're not starting new threads and instead posting to someone else's ones. It's now very hard to manage which answers belong to which questions. :-[
compumedic, Too many open sockets - is this really the message you got? Can you download and run TcpView from http://www.sysinternals.com/ntw2k/source/tcpview.shtml and post its results? BTW first you said you couldn't access the web (at all) and then that browsing became slower - so it DID work, after all (but was slow)?
essexboy, OK, I'll try to simulate the problem here. Thanks
cherrycola, so the Internet doesn't work at all? Or just sometimes, you get a timeout message?
dj_don, first, I understand your frustration that things stopped working but I can't agree with your attitude. No one's burying head in the sand - these really ARE conflicts with other software. Saying that it must be (only) avast because prior to the update, everything was working OK, makes sense only partially. The new avast release (4.6) adds NEW features - such as the WebShield - that were not present in earlier versions. The WebShield is a network application and as such, is subject to inspection by a firewall (if installed). If the firewall (for any reason - intented or not) denies WebShield access to the net - you see the effect that you're seeing. We've tested the new features with virtually all firewalls on the market today, and yet, there seem to be some conflicts. I guess the world is still too diverse for us to test all the cases.
That said, I'd need some more info. Particularly which sites don't load (if not all), which browser are you using, what version of ZA/Norton etc...
Thanks
Vlk
-
essexboy, you're right! The Privacy Control settings set to High are indeed causing the conflict.
I've found a workaround that works, though.
Set up the proxy settings in Firefox as shown on the following screenshot.
While this is not a definite solution, as a temporary workaround it seems to be working pretty well. :)
Edit: maybe I was talking too fast... ;) The proxy trick doesn't seem to so reliable work around after all... :-\
Thanks

I had a similar problem last night. XP sp2, 512 RAM, using both Internet Explorer 6 and Mozilla 1.7.2, and Kerio 2.1.5 firewall.
I started having trouble with Internet Explorer. Part of the page would load, and other parts remain empty. Also, the fonts changed on the various sites to a very small size. I switched to Mozilla and it worked for a while and then the same thing began to happen. This was the same on every site I visited, including this forum. No matter what I did, the problem persisted until I shut down the computer for the night. Today, it's all normal again.
My first thought was that it was because I hadn't shut down the computer in a couple of weeks and it was Windows telling me it was time. After seeing this thread, I thought I should comment on the problem.

Ok !
All network traffic seems to be scanned by Avast! (even if the On-Access Protection is disabled) !
Symptoms:
- Web pages does't load correctly or not at all
- Services won't work : FTP: It takes 10 retry to connect, but no passive mode allowed
The problem appears only when I have a lot of socket open, just to mention that I tested with a BitTorrent Client (Azureus).
If I close my BitTorrent Client, everything goes fine after 10 seconds ... The problem doesn't comes from my network settings or a firewall. I got no firewall (just a fully functionnal router).
I also tried to Enable / Disable the QoS settings in the Network settings with no success !
Informations:
- OS: Windows XP SP2
- IE : 6.0.2900.2180 (comes with SP2)
- Firefox: 1.0
Is there a resident shield activated even if I stop all the services in Avast! ??
EDIT:
Here is what is get in Firefox ... When I get something !

milhouse69, which firewall are you using?
-
No firewall at all !
Just a router (Linksys) that makes the NAT between my computer and the Internet.
And the Windows XP SP2 built-in firewall is disabled !
-
compumedic,
the message:
Too many open sockets.
\Device\HarddiskVolume1\WINDOW\system32\opsq.exe
suggests that the process opsq.exe is trying to access the internet and possibly it has lot's of connections at the same time. Do you know what this opsq.exe is? For example what shows the "Version info" about it when you choose properties of this file in Windows Explorer?
Thanks.
Lukas.

I am having the same problems with the same error messages.
Has anyone figured out what to do about this yet?
I also downloaded the new avast.
-
read this it may help
Well here we go
Im using MS outlook and aol
in ms outlook >>tools >>accounts >> properties >> advanced >> outgoing mail (smtp): default port is 25, aol recommends 587, so times ago, I entered 587 (for france)
Hense in avast >> resident protection >> webshield >>personalized >> port http: I replaced 80 by 587
it also works with 25

I hope I am not confusing this problem but it sounds similar to my problem. If I should start a new problem, let me know.
I have only been using Avast for about a month and thought everything was fine until last week. I am using bluelight dial up and IE6 with XP pro & Sp2. I started getting the messages re "too many sockets" and avast proxy. It always always had a reference to "etrends" which is a tracking prog. I have had for a long time. I had grandchildren using the PC and thought they had messed with something and did a system restore. That fixed the problem for a day or so???? WHY?? Then it came back!! I know just enough to be dangerous. so I ran msconfig and turned off all 4 avast lines in the process sections and have not had the problem since. I would like to turn avast back on but I don't need protection if I can't get to any web sites. Every thing I tried came back with the same red message. I will watch this site for a fix.
Thanks for any help you can provide
-
Rlkeator, try to disable 'only' WebShield from avast control: left click the 'a' blue icon in the system tray, choose WebShiled provider at left and shut it down. Try to see if everything works and let us know... Then we can correct your problem later...
Welcome to avast :)
-
When I click on the Blue Button with a in it I get a window called " avast! On Access Scanner " Status: active Normal/high is at normal.
Clicking details give a window with:
Instant Messaging
Internet Mail
Network Shield
Outlook /Exchange
on the left side. All are running except Outlook.
Since I post my problem, I went back to msconfig & turned on every thing but "Web Scanner" and every thing has been working.
It shows as "disabled" in Services window.
I started in manually and clicked the "blue ball a" and had the same screen.
This is Avast Ver 4.6 Home Edition.
Thanks for your reply I will start the web scanner and see if I get the error.
-
Bac again. I started the web scanner again and my Isp kicked me off before I could test anything. (I don't think there is any connection between advat and isp quiting) but as I was closing windows, my yahoo mail screen had the error message. I will leave the web scanner off till I hear from you.
thanks
-
Now this ones a bit weird. When I try to go online firefox says no data on the page and doesn't load a page, IE gives a 404 error. Terminate webshield (pause doesn't cure the problem) access one page restart webshield no problem with either IE or FF. Spooky or what. No further problems till I reboot then I have to go through it all again Avast ver 4.6.614 just downloaded (well prior to this anyway). ZAPro full server access to webshield.
-
Try this work around fron the ZA sticky thread.
There's another work around that seems to be working. It consists of setting up a proxy server in your browser, with the following details:
proxy server name: localhost
proxy server port: 12080
For firefox, see image

Why did this topic just quit?? I turned off the web scanner part of avast and now can use the internet but there has been no updates since. Will this be fixed??
