My wife downloaded some songs off of the internet a couple days ago, and yesterday when i tried to turn on my computer it would freeze everytime during boot-up. I ran a system restore and now it boots up fine. However, before the restore i had almost 60% of my little 40GB HDD empty, when i restored my computer i dropped to 46%. Now i am down to 35% empty. I did a virus scan and deleted or quarintined all known viruses, but now i have only 35% free space and my computer is running like Grade A garbage! What can i do!!!
