So I just got home from my friend's house, turned on my computer, and I see three icons on my desktop that were never there before, one for "Error Cleaner" one for "Spyware & Malware Protection" and one for "Privacy Protector". Then I go to do things as usual...and well...EVERYTHING is gone.

No really. When I hit the start button, there's no programs, no my computer, no control panel, etc, it's just blank with my frequently used program shortcuts. If I try to open the task manager, it's greyed out and won't let me. If I even try to change my desktop background it says "Your administrator has disabled the control panel". Also, if I go into My Computer via the Recycle Bin, the C: drive IS GONE. Completely gone. Also there's a little red blinking "x" and "VIRUS ALERT!" in the system tray, and the time has been changed to military time, meanwhile stupid popups for virus software keep popping up, Internet Explorer randomly opens and goes to related sites, and it will only allow me to go to certain websites...if I Google anything related to viruses, trojans, or spyware, I'm re-directed to one of their stupid ad sites. I'd provide a picture, but because of all this I can't access Photoshop or even MS Paint.

So umm...if anyone has any advice that'd be great.
