Problems!

Hi,

Just recently I've got this problem with my wallpaper that says Warning Spyware detected on your computer Install an antivirus or spyware remover to clean your computer. I've downloaded some antiviruses like Window Live OneCare and SpyBot. They removed some dangerous files but I still have that desktop wallpaper for some reason.

On top of all that. Each time I restart my computer and log into my account in the computer. While its loading it'll turn black and a blue screen will appear that says something along the lines of:

"Windows has to restart as prevent harm to the computer" (Something like that don't remember all of it).

Please help!
