I hadn't updated in a while but decided to do so yesterday. The updating was not a problem but afterwards my computer started acting up. When I would click on a program the program would get hung up and I couldn't close it. Shutting down became a problem. The only way that I could get my computer to work again properly was to run Norton's Ghost. I have windows XP home. I run Win Patrol, Process Guard,Spybot Teatime and Microsoft Anti Spyware. I have had all of these for a while with no problem Recently I added Ghost Surf and CounterSpy beta version 1.5.62.
