I was fooled by test results, I admit I thought NOD32 was the best there was..I was proven wrong..The same can be said about AVG or any other AV..The main thing I find is use the one that lets your machine run smooth,then do on line scans
once in awhile..You always see people complaining about Norton,the reason is so many people use Norton..I believe out of all the free AV's ,AVG would fall in that category ..These tests were performed by people knowing the importance of not having a controlled environment ...I'm sure they could perform the same tests and have different results.
