At the beginning of last year Nortons Internet Security 2009 got such great reviews I decided to give it a shot and was pleased with it enough to install it on 6 machines, it was a better product than Nortons earlier AV protection that added everything in it but the kitchen sink and slowed your machine to a crawl.
Then Symantec released NIS 2010 and 2009 began automatically updating to 2010, which got infected with a virus on 3 different HDDs, 2 running WinXP Pro 32bit, 1 running Vista Home Premium 64bit, Nortons was clueless it was infected, but Windows Media Player began relentlessly restarting basically rendering you computer useless.
After many failed attempts to stop the problem I decided to try an online scanner, even though Nortons continued to report no infection no matter how deep the scanner was set to run, I took a shot in the dark and chose ESET [NOD32], installed and ran its online scanner, it found all the virus infections and removed them.
So now I'm running the 30 day trial version of ESET Internet Security and so far its getting a thumbs up, hopefully that will last.
Nortons is still clueless of the virus, thats a real let down from Symantec, they should have been all over this thing by now.
Well that's my 2 cents on this subject. Ryan
