Short version: Avast and Kaspersky anti-virus packages have started bundling web scanners that process all http traffic. They don't play nicely with Firefox 2+. If you want to keep your present AV software, try disabling the "scan all files" web protection option and enabling scan only for executables in web traffic.

Long version:

I've had the intermittent page load failure and timeout issues since installing Firefox and Thunderbird updates in July [Windows XP Media Center SP2, Gateway laptop w/ Intel 9345ABG onboard wifi], worse with each successive update. A desktop computer on the household network also had some Mozilla issues since the update, but the problems were resolved completely after switching to OpenDNS.

Having gone through all the proposed fixes in these knowledgebase entries and forum threads (e.g. using OpenDNS, disabling AV software, flushing cache, trying new profile, uninstall/reinstall, about:config settings, etc.), I achieved varying degrees of improvement, but no consistent resolution:

Diagnostic results:

This is an intermittent and difficult-to-reproduce problem. While the pageload failures seem like a DNS issue, it's local to Firefox (and Thunderbird!), since IE often loads the same pages without difficulty. Wdnslookup usually shows no appreciable slowness or name resolution failure on the same sites that don't load properly. Hardware firewall with UPnP, all appropriate ports opening and closing, no problem passing traffic for IE.

Things that didn't resolve the problem:

Disabling extensions;
Clearing cache, history and cookies;
Running Firefox in safe mode;
Flushing the DNS cache with ipconfig;
Resetting about:config modifications
Turning off IPv6 support;
Creating a new profile;
Antivirus and malware scans;
Uninstall, removal of all registry entries with a cleaner, followed by reinstall of Firefox to a new directory;
Updating router firmware and network drivers;

Things that provided improvement:

Using OpenDNS. [My ISP, Comcast, is notorious for DNS problems.]
Disabling my antivirus software (Avast 4.6) [The other household computer uses TrendMicro]***

Both Kaspersky and Avast anti-virus packages have started to incorporate web scanners that inspect all http traffic (Avast 4.6, Kaspersky AV 7). Avast's Web Shield component uses a "transparent proxy" to permit on-access scans of http-requested data. According to Avast's knowledgebase, some situations [Zone Alarm w/ Privacy Control, non-NT OS's --- see http://support.avast.com/index.php?_m=k ... ticleid=22] require this proxy to be manually bypassed in Firefox. This wasn't applicable in my situation, but I was able to keep my anti-virus software running and eliminate the slow page load/timeout problem by turning off the Web Shield ==> Web Scanning ==>Scan All Files option, and instead scanning only web-based and downloadable executable files [ADE,ADP,BAS,INF,INS,MDB,MSI,JS,EXE,ZIP,RAR,ASP,ASPX,COM,BAT,PIF,VB,WS,VBE,VBS].


***The EnumProcess utility detects the Avast engine, but does not detect AshWebSv.exe, the Web Shield service.

Best of luck to all!

EnumProcess was intended to find firewalls. If you can give me the complete output line of enumprocess i can add it to the suspicious processes. At the moment i have added it to the firewall processes. I think i have to sort the processes a bit better. ;-)

Edit:
I still need some reports for Kaspersky and Avast to get the company information.

EnumProcess should list all running processes, and it shows firewalls in red. It <i>detects</i> AshWebSv.exe if it's running. It just doesn't show it in red because it's not actually supposed to be a firewall. Isn't this what you mean, patienceltd?

An addendum: I _did_ need to update the proxy settings in Firefox per the Avast instructions; I made the change (redirecting localhost to port 12080), then forgot that I had made it. When I undid it, the problem recurred.

VanillaMozilla: My apologies --- EnumProcess does detect the AshWebSv.exe process, without highlighting it as an anti-virus program component. Perhaps this and the AshMaiSv.exe (Avast mail scanner) component can be added to the suspicious processes list?

Thanks again for your hard work and assistance with this problem.

At the moment, I haven't Avast, but I've been meaning to download it. If I get it and disable that, will I be guaranteed to not have any problems?

If i add "ALWIL Software" as manufacturer all processes which has that company information will be shown as suspicious.
I'll upload a newer version later. I can only do that at home.

I saw where Lost User 293953 suggested "disabling the 'scan all files' web protection option and enabling scan only for executables in web traffic." I'm using Avast 4.8 Home Edition (free) and can not figure out how to disable "scan all files." Can anyone help? I'm not a computer whiz, so step-by-step would be helpful.

Thanks much.

Oh, you might try right clicking the little blue Avast tray icon for it's options.
