I just installed avast home edition and when i run skype, IE and Firefox just doesnt load pages. Internet connection is allright.

Is there any other antivirus installed?
Which firewall do you use? Did you allow ashWebSv.exe to connect?

There is no other anti-virus installed and i dont use any firewall. When i disable webshield, then everything works properly…
