Virus Bulletin : News – A third of anti-malware products fail to secure Vista Business Edition, Virus Bulletin reveals.
If you look at the linked graphic you’ll see AVG proudly near the top with Symantec and Macafee much lower. Microsoft Security Essentials isn’t high on the chart either..wow. So if you really want an anti-something i would go with AVG for both home and business use at this point. If you head here you can see that Macafee actually failed this test. Symantec passed however i can tell you from personal experience I wouldn’t run it as i have had to clean up many machines with Symantec installed..:)
