DELL Precision 380 with XP Pro. Just got the PC and was updating and installing software. I don't think it had it when I first started. I'd hate to start over but may need to. I had AVG and SpyBot running.
I ran through your 8 recommended steps (attached the 3 logs). As I saw in a few other threads it went away after finishing however it came back after a reboot.
The HJT log is the most recent after the reboot.
Update: I saw another thread where Hitman Pro 3.5 cured the problem. I think it found it ... but when I try to remove it's actually removing a key driver and crashing me to a blue screen where I restore my last version (still infected). It says I have a Trojan named iaStor.sys in \system32\DRIVERS
