Okay, I feel like a total lamer for posting a question about how to delete something, but I don't know what to do. So I'll suffer my humiliation and hopefully find an answer for my problem.

Anyway, disclaimers aside, I was trying to clear the spyware off a friend's computer using AdAware, and it told me some files could not be deleted. So I hunt them down and try to delete them manually, and I get the following error: "can not delete ~file~: access is denied
Make sure the disk is not full or write-protected and that the file is not currently in use." I checked the thing's properties to make sure it wasn't write protected, and rebooted and closed all programs and as many active processes as I could to make sure that it wasn't in use by anything, or as sure as I could be, at least. And it stll wouldn't let me delete it or even rename it.

So then I decided I'd be crafty and try and delete it from the DOS window, that didn't work. So then I went back to my dorm room got my Knoppix CD, and was gonna try and delete it from a Linux window, but for some reason her computer wouldn't run the Knoppix CD.

Bottom line: how the hell do I delete this thing?
