Ok, u guys helped me out b4, but now I have more problems.

Right after a scan, Ad-Aware crashes.
It detected 86000 threats (no exaggeration) on the computer.
I have at least 2 instances of every program on the computer, and I’m prettty sure some of them are worms.

So here’s wat I need help on:
How to delete all that detected malware from my computer
How to identify which programs are malware from crucial programs.
Troubleshooting Ad-Aware
Any other tips on cleaning up my computer.

Thanks!
I have Windows XP

Norton and Ad-Aware as defences.

Should I get AVG?
I don’t have spyware popups or wandering mouse. (yet) Just a lot of suspicious software and lag.
