Delete a trojan?
 

Any suggestions for deleting trojans?

I have a few on my computer. I'm a little concerned. I found them a few days ago and I'm really frustrated. I can't seem to delete them. I've tried granting myself admin access. Doesn't work. DOS prompt can't find the program files folder for some reason but then again I'm not very good at command prompt stuff.

I need to pretty much bipass my administrative permissions and just delete the file.

Yeah it's Windows Vista.

How do I just find and kill the file? Program? Method? Code snippet? Anything?

Thanks you guys for sharing such a very useful information.
