I am new at this but am trying to learn. I am running Windows XP home edition. The computer was bought in 2002 but sat for over a year offline. I recently got it hooked back up and everything was out if date of course. My problem is that I keep getting viruses that block me from browsing the internet. I had problems using windows update at first, but now I have it updated to SP1. I’m running avast (free version) and zone alarm (free version). I also have the free ad-aware.
I’ll be online and all of the sudden I’ll get cannot find server pages and will have to do a system restore or run a boottime scan to remove viruses and get it working again. The latest things avast found were Win32:Gaobot-829 [Wrm] and JS:Gummy [Trj]. I’m attaching my hijackthis log to see if anyone can please help me. Sorry this is so long but I’m new at this.
