My pc was recently infected with some viruses and spyware. After cleaning most of them up with my anti-spyware and anti-virus (PC tools spywaredoctor and PC tools antivirus) there is one left that i can't seem to get rid of.

The infected file is C:\WINDOWS\system32\cbxwtur.dll

I can't do anything to this file when not in safe mode because i recieve an "access denied" message.

When i boot into safe mode on the administrator account the file is being used by another person or program.

For situations like these, I usually use a program called "moveonboot" to delete it when the pc boots up, but this isnt working for some reason.

I have also used the system file checker and repaired my windows installation.

My anti-virus also can't delete the file and says it will delete it on reboot, but apparently id doesn't.

Before i repaired windows, i would sometimes get a BSOD especially when i started a program.

I'm pretty sure viruses do this quite a lot, so im hoping someone could tell me what i should do.

I'm using windows xp service pack 2 and i do not have an available restore point.

Suggest you run the Prework-- from the link in my sig below.
Our security team experts will help you remove whatever it is...
When you get to the end-- be sure to post your logs in the HJT logs forum-- so you get swift attention.

ok thanks bud. Unfortunately, the night after i posted this, my comp became so bogged down i gave up and reloaded windows on top of my old installation. If this problem happens again i will definitely follow your advice.

Thanks for letting us know
