Can you activate logging in WebShield?
0. (Disable avast self-defense module: Program settings > Troubleshooting tab of settings.)
Edit \data\avast4.ini file with Notepad (or use step 0 with other text editors).
Find the section [WebScanner]
Add the line:
EnableLogging=1
Restart Web Shield in XP\Vista (terminate and start again) or whole PC in case of Win98
Browse (trying to access some webpages)
The log file are \data\log\ashwebsv.log and ashwebsv.ws.
They would be accessible when WebShield is terminated again.
Post them here or send by mail to rypacek (at) asw.cz
After that, disable the logging to avoid a big log file.
Oh, enable the self-defense module again after that if you have to follow step 0.
Can you try to repair your installation?
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair).
http://www.firewallleaktester.com will not be available for a few months from now primarily due to the money it costs me each month (more than 40Euro).
Why would they want ZoneAlarm when it causes problems?
