I am woking on a friends labtop, but he is having problems with spyware and adware as well as the fact that his computer will just freeze up on him. Pop-ups are a big problem. I tried to clean up his harddrive but one file in particular has been tormenting me 00THotkey.exe. I can't figure out what it is. I had him download Zerospyware to get rid of the spyware and adware, but it hasn't fixed the problem. Can someone tell me where I need to start?
