Hello,
I'm also having a problem with WebShield on my computer since update. Configuration is WinXP SP2 + latest Microsoft updates + Spybot v1.5 up to date and AVAST 4.8.
If I activate Webshield, then I'm not able to connect to any website neither with IE 7 nor with Firefox.
The behaviour is the same even if WinXP firewall is not activated.
If I shut down the Avast Webshield, then I'm able to access all websites... I tried to remove and install avast again but problem remains.
This problem seems to be encountered by some of Avast users but I must say I had no other antivirus software installed in the past (perhaps Symantec evaluation version when I bought the computer but I don't remember because I uninstalled all evalaution versions of all softwares).
From my point of view, it looks like the redirection through AVAST for IE/Firefox or in the way is not working. Others protocols are working fine (POP, SMTP, PING, ...). As behaviour is the same with/without XP firewall, I think that a setting for the http stream's redirection is not working, perhaps something wrong in the registry or something like this.
I tried to activate Webshield log but nothing is written into the file when browsing...
Is it a specific key describing redirection I can search in the registry ?
