It gives details of the files C:\windows\system32\<some long random looking filename here>.dll
Apparantly the files don't exist when I try to remove or heal them.
Any ideas?
P.S. Just tried to get HiJack this and it installed, then said there may be problems installing, then when I tried to run it it just siad HiJackThis has stopped working

Excuse me, I am a Unix user. I don't usually have this kind of problem and I'm a bit of a windows noob.
