I installed Spyware Guard and MRU Blaster yesterday, updated and all was well. Signed off the internet and left the room for several hours. When I returned, the screensaver was locked up, finally got it off. The desktop picture was gone and the screen was blue except for the icons. Windows Task Manager said CPU usage was 100%. I rebooted and removed the two programs and everything ran allright all day today. I am running XP SP2, AVG Anti Virus, Spywareblaster, Spybot S&D, and Microsoft Anti Spyware (Beta). Am I being overcautious and running too much?
