i run xp3 and have zonealarm as my firewall, also windows spyware terminator but the update to avast 6 just slowed my netbook till it froze and no internet connection. Only way I have recovered my system is a system restore back to 3rd week in february and am leaving the computer in hibernation mode, not letting it shutdown because I know avast will update and lock my computer. Help because avast has been best antivirus software I’ve used and would like to continue using it.
