So the gamer mode on ESET Smart Security 7 doesn't work? It does and I rarely have to enable it when playing ANY GAME.
I wasn't saying Gamer mode doesn't work. But your input raises a couple of further questions... How exactly does the gamer mode work? I have it on in Avast and it works, too. In my case it means that no pop-up messages are shown. It doesn't stop downloading signatures, though. It may even do some background scanning during gameplay, I don't know. Do you? Does Eset stop the Vulnerability Shield or Exploit Blocker in Gamer mode? I doubt. Besides, Eset Smart Security isn't an all-in-one in the measure like Norton 360. Based on the information given on Eset's site it seems to be just an anti-virus with a firewall, the functionality listed separately for marketing purposes.
Speaking about Norton360, it has all that and lots more. There's a built-in temporary files cleaner, a defragger, a backup reminder and what not. Back in the days of yore Norton had five different products for sale and back then they were superb compared to their Windows equivalents. Today they've packed all of them into a single package in the name of customer service and simplicity, causing people to go crazy with all the nagging about the computer being vulnerable because no backup has been configured etc. For a gamer it's even worse, the 360 seems to do all kinds of maintenance things every time it thinks the computer is idle - like during a bomb run...
