All of sudden, when I turned my pc on, it said it was infected and I can't access anything. This 'program' came on screen saying to activate my spyware and I tried. The whole thing appears to be fozen. I can't even access my Control Panel or Spyware. The only thing that appears on screen is that my pc has been infected by malicious threats etc. Help!
