...so clean it squeaks, jb. You could fix that O2 entry with no file, but it was never a problem BHO -it's a common enough CLSID.
Were/are there any symptoms bothering you?

mmm its worrying me because windows keeps telling me thats it system files have been modified by an untrusted source.

I guess they are not the system files that are included in the protected list, otherwise the file protection sys would have kicked in and replaced em with originals.... Could it be a driver? I'd have thought an untrusted source would have buckley's of doing that unless some permissions were altered. Don't know. Sorry. sfc may sort it out, but that would mean that the cache files were wrong also...

Yeah the file protection thing keeps coming up on bootup and saying something is trying to replace winlogon.exe but it obviously fails as sfc /scannow completes sucessfully.

Haha.. you def would not want winlogon.exe replaced cos win file prot runs inside that! I can only think that a trojan or virus with just one job in mind is resident, it fails and stops until next reboot. O20 is where you would hope to see that launch type being reported, naturally with windows I bet there are many other winlogon launch methods. I can only suggest doing a couple of online scans, an eg is Panda Online Scan:[what follows is a set piece...]
==Please do an online scan at panda:- http://www.pandasoftware.com/products/activescan?
-select a link to the scan... free online virus scan...., enter a valid? email and follow through, choosing My Computer for a full system scan.
Post the log it produces here.
Give it a shot....

nod32 and avg detected nothing

i think some nasty trojan is trying to replace my winlogon in order to capture my password etc...

sfc /scannow fixes it but only for that reboot.

Im gonna backup thyen delete the cache directiories and any copies of winlogon i can find and replace them with stock ones from the xp cd
