In relation to this topic where I stated that my dad brought in two laptops for me to fix, I'm having problems with another one. This time, this one has an OS, and I finally completed cleaning it out. Yay! But it's mysteriously hanging now. Boo. I've ran all my cleaners and virus stuff, no dice. I think there might be a rootkit, but I dunno. Any suggestions? Edit: One more thing, it's been trying to stop me from obtaining updates from Microsoft Update.
