Ad-Aware not working...

Hi all,

I loaded up Adaware from this site onto a friends computer. It seemed to be running great, and fast, as usual. Then when it gets towards the end...it just says busy and gets hung up. I tried to hit cancel and just remove what it did find, so i could narrow down what the problem is, but nothing happened and no list was shown to me. I've concluded that there is something on his computer that is causing this to happen. I've run Spybot, HijackThis, CWShredder, etc and all have worked fine and removed any problem items.

This one is drving me crazy. Please help.

Thanks
Chrono
