Should I continue using NOD32 3.0.684 or upgrade to 4.0.314 now? An honest opinion from those who upgraded would be appreciated. After reading the forum, I'm inclined to wait several months until the bugs are resolved. What 4.0 improvements make it worth upgrading now? Are the bugs annoying enough to wait? What advice do you have for us 3.0 users? Thanks. P.S.: Does 4.0 add the ability to click "Add to Exclusion List" When a warning pops up - or do you still have to manually enter it in the exclusions list?
