I switched to NOD32 from Norton because it was antithetical in every notable way: negligible memory footprint; insignificant processing consumption so it can run even while gaming; and the older versions had none of the nuisance factors found in the other anti virus products I tried. Being simple and effective was appealing and why I've used it for years and recommended it to family and friends. If I wanted it to stop running or close the program entirely, it was that simple. As of this writing, that doesn't happen any more and the icon is omnipresent to perpetually remind me that it's been disabled. It bombards me with unncessary notices, the latest ones to inform me that my "Operating System is not up to date" because I've elected to _not_ install some Windows 'features' (what the hell does not having WMP 11 even have to do with my anti virus functionality?) If I take my laptop anywhere and it's offline for a period, I get even more nuisance popups telling me that it can't connect unless I manually go in and disable the update scheduling, which then gives me more notifications that it's out of date and purportedly at risk. And if I elect to not run some features that I don't require like email scanning, I get even more notices because it's convinced I must be insane to not want it enabled. In other words: NOD32's annoyance factors have outgrown its utility and clearly has stopped being worth using over any other anti virus. Because for some reason they decided that it should mimic the worst parts of competing products which were the reason I switched in the first place.
