I somehow got a trojan on my PC yesterday (Dell XP SP2, only a week old!). After reading some helpful tips here, I was able to remove ipwins.exe and update.exe and svchosts.exe. They no longer appear anywhere, but something is still hogging 50% of my CPU time, (and I've got a dual core), so I'm guessing I didn't get it all. I've run AVG AntiSpyware, Spybot, Norton AV, and they say I'm clean. I'm attaching my HJT log. Any ideas what could be left? My PC is only a week old, but I've transferred all my stuff to it and got it all set up the way I like. But would it be easier to just do a clean format and reinstall the OS?
