» Robert Dailey - Backweb: Adware?

Hi, Michael.
I regularly (daily) delete temp files and cookies through my "internet options," but I also check irregularly on %temp%, just to see if what I think is going on is actually taking place.
When I look at %temp%, I see a file in there titled "IadHide."
First, is this spyware or adware?
Second, I can't delete the file through ordinary means. Any ideas if I should and if so, how?
Third: I'm running Norton and Webroot Spy Sweeper on my system. These should have caught something like this but haven't.
Any ideas?
