I have the same or similar Issue. I just recently have installed ZoneAlarm Security Suite. I had no expert rules set yet, but when I try to set a expert rule for Utorrent the computer completely freezes when I start Utorrent. I have to restart the computer to regain control.
The Rule settings are,
Source: Internet Zone
Destination: My Computer
Destionation port: Other Any
Source Port: Other Any
Windows Vista Home Premium Service pack 2
Zone Alarm info:
ZoneAlarm Security Suite version:9.0.112.000
Anti-virus engine version:126.96.36.199
Anti-virus signature DAT file version:995207680
