OHHHH! I see why you switch off your AV. Your still running Symantec. Seems that all your years in IT hasn't taught you anything.
Symantec is #1 useless, catches mostly nothing and most malicious code is written specifically to go around Symantec products cause it is the most widely used AV.
#2 it is the biggest hog of resources of any AV on the market, I see why you disable it.....It's like a virus in itself because it uses so many resources from your PC.
And I wouldn't advise anyone to switch off their AV, not something that someone in IT, especially in IT as many years as you claim, should be suggesting.
And I agree, if I get a virus, no big deal, easy as *** to remove....but for a lot of people it isn't so easy. There are a majority of people on the net these days that don't know much about PC's and removing viruses without help from someone is impossible for those people, hence why I don't think it should be suggested.
Scrap that Symantec and go get a real AV client....you won't have to turn it off to play games, and when you do, you won't notice a difference because there are many AV out there no that aren't very resource intensive, like the hog of all Symantec products.
