System unstable after removal of malware

Specs: Windows XP
Hi all,

My computer was infected with a virus/malware on Sunday night. It somehow bypassed AVG...The symptoms - high use of processors (in task manager, System Idle Process was typically gobbling up 40-50% of the CPU), random fatal freezes (it would hang for a moment and then freeze entirely, usually a few minutes after start-up), notifications that I was infected with malware and should download a program, etc.
Persistent scanning with PC tools spyware doctor found a ton of stuff, and removed it (this included braviax.exe), but it always respawned after rebooting.
A full scan with malwarebytes in safe mode subsequently found the mother-file (whatever you call the source of the thing) and deleted it, and now all scans are showing up as clean.
Problem over, right? Nope. The system still seems very unstable, crashing soon after boot (NOT on safe mode, I should add), particularly when using applications of any sort (windows MP3 player, for instance). MSN messager also crashes immediately after I sign in, which it never used to do. CPU use also seems persistently high. But like I said, scans reveal nothing. I haven't done a full scan in non-safe mode, though, for fear of it crashing part-way through.
I should stress that the PC was entirely stable until it was infected with the little b****** of a virus on Sunday night.
Please help, I'm at my wits end here (sorry for the long post).

Try a quick scan in normal mode of MBAM , sometimes it cannot find everything in safe mode
