which is better AVG free or Windows One Care?

Answer 1

I would go with AVG free. Unfortunately, Microsoft's Windows OneCare failed a standardized test which is given to all antivirus programs. They are used to certified an antivirus program as being able to detect and remove all "in the wild" (i.e. viruses currently infecting computers) viruses. Windows OneCare failed not once but twice. AVG free passed on the first try. You can read about it at:

"Microsoft Acknowledges Anti-Virus Failed VB100 Test" -- written by Betanews.com (http://www.betanews.com/article/Microsoft_Acknowledges_Vista_AntiVirus_Failed_VB100_Test/1170809025).

A Microsoft spokesperson confirmed to BetaNews this afternoon that it has learned its Windows Live OneCare anti-virus package has failed a test conducted by the respected British laboratory Virus Bulletin using Windows Vista Business Edition, disqualifying it from carrying the "VB100" logo denoting 100% detection of a selected battery of common "in the wild" viruses.

Answer 2

I have used AVG with good results, but then I have never had a virus on the computer to date ( Touch wood! ), so can't really comment on the effectiveness of the cleansing function.

Sorry I don't know anything about One Care.

Answer 3

AVG is good
