Is it possible to buy 2 ea 4 packs of the NOD32 AV program for our winery? We only have 8 Windows XP machines in there that connect to each other/winery. Right now only 5 are protected with AVG anti virus program and when they come up for renewal, I'm contemplating changing to either Avast! or NOD32. I believe either program will be a superior working AV program to our existing AVG. It (AVG) has some issues with working and scanning how I want it to. More difficult for the users to control themselves at times as well.
