no i believe the guys making the anti virus is the same ones putting the viruses out (im mean they have to make money and no OS is perfect). Like the guys that make ur pills or meds arent' cureing the problems they're just making them worse, but thats my opinion. Low and behold and knock on wood mine have NEVER had a virus, but plenty of other ppls machine that HAVE installed an anti virus or some kind that ive worked on have had plenty of problems, and no i can not and will not format my drive, ive got too much crap on here anyway.
