In case the fix doesn’t resolve the issue, it is most likely that the avast! Web Shield process is blocked by a 3rd party firewall (pre-)installed on the machine. Please make sure to let the Web Shield process (ashWebSv.exe) the right to access the Internet.
Thanks

PS. The fix will also be included in the next avast program update.
Thanks VLK. I can say that this works successfully!
Although it caused me a couple hours of pulling my hair out wondering why my web surfing was not working I would like yo congratulate Avast on their prompt response and fix to the issue.
Hi, I still have problems after installing the fix…
can you give me any suggestions how to verify if the Web Shield process (ashWebSv.exe) is having access to the Internet?? (internet options?)
(my windows’ firewall is not activated)
I’m just setting up a new system (with preinstalled Vista) – I can access the Internet (Web & email) when I turn off Avast, but once it’s on I can’t get connected. (I turn off On-Access Protection and I can get through.)
I tried the suggested fix – it didn’t help. I made sure Web Shield is allowed full access – it is. I tried turning off the McAfee Security Center that came preinstalled – no-go either.
The email error message is:
Account: ‘AccountNameHere’, Server: ‘mail.comcast.net’, Protocol: POP3, Server Response: ‘-ERR concurrent connections limit in avast exceeded(pass:20, processes:emproxy.exe[19], WinMail.exe[1]), there is a collision with another program’, Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC90
Any suggestions? Please? I don’t want to run without Avast.
Disabling McAfee is probably not enough. Its email proxy is still active and collides with avast mail scanner. You need to uninstall it if you want to use avast.
Okay, so I have to uninstall McAfee – I’ll try that (although I hesitate because if it doesn’t work then the system is not going to be protected by anything) – but will that help the Web surfing problem? (People are mentioning the solutions for email, but it was also Web that was affected.)
Well, you could use all McAfee solution (firewall + antivirus) or you can try another free firewall (like Comodo), although there aren’t that many firewalls prepared for Vista (specially free ones).
