I have a friend who's mom asked me to check her computer out. She had that damn homepage-network crap that keeps resetting her homepage, she was getting popups, all that crap.
I sat there for over an hour cleaning that computer out, even put in a few speed tweaks and it was working like a champ.
A week later, my friend tells me it's doing the same thing again.....his mother is thinking about getting a new computer.
So he brings the tower over, and I check it out.....same crap in there again.
Turns out, HE is the one surfing crap sites and causing the problem. Told him to quit that crap.
I clean it out again, he takes it back.....2 weeks later, same problem.
She calls Dell, buys a new one, gives the old one to him.
