Microsoft Live OneCare Can't Fully Protect Vista

And they wonder why people who use Mac's and Linux rip them.

(ZDNet) The researchers tested whether each of the antivirus products would stop a set of viruses known to be currently circulating. In order to be awarded a pass, the software had to detect all the viruses with no false positives.

But out of the 15, four failed: Microsoft Live OneCare 1.5; McAfee VirusScan Enterprise version 8.1i; G DATA AntiVirusKit 2007 v17.0.6353; and Norman VirusControl v5.90. The other 11, including software from CA, Fortinet, F-Secure, Kaspersky, Sophos and Symantec, detected all the viruses.

Good stuff.
