I used to use Norton Anti-Virus, but last week a friend suggested trying out NOD32. So today I finally picked up my copy of the NOD32 Anti-Virus from the local computer store. So I installed it and immediately noticed some big differences. It uses far less memory and scans the hard-drive amazingly fast. It also alerted me of some viruses in my computer, that Norton Anti-Virus didn't detect for some reason. I already feel much more secured by using NOD32. Try it also!
