I have the feeling that windows vista is the most worth windows that microsoft have made. I a piece of crab.

I have this problem my window vista freeze when I run windows defender, verizon suite virus scan o spyware scan. It seem also that can not make multi-task. If I run the virus scan i can't work in other aplication. But know the problem worse because the scan freeze my computer and i have to turn off by the power button.
