Hands down for ESET NOD32 Anti-Virus 4 is THE best. The old NOD32 sucked big time, but the new version is amazing. I can understand why you go rid of it. But with the new one you don't realize it is even on your system. Light weight, doesn't bug you, and doesn't make start up time slow. It deletes known viruses without telling you or bugging you. If it suspects something is a virus it quarantines it until you take a look and choose if you would like to delete it or not. It also warnes you about fake links and sites like the ones listed above :D
