Fair use excerpt:
The security testing group found that Live OneCare missed far more active viruses than any other program tested.
When Vista was launched on 30 January, Microsoft chairman Bill Gates claimed that it was "dramatically more secure" than other operating systems.
Reading the results at Virus Bulletin, the following products achieved the VB100 award on the Vista platform:
Avast, CA, Quick Heal, NOD32, Fortinet, AVG, Kaspersky, Sophos, and F-Secure. Each of these detected and prevented 100% of all known viruses and variants.
The following products did not achieve VB100 as they did not detect all known viruses and variants:
Live OneCare, G-Data AntiVirusKit, McAfee VirusScan Enterprise 8.51 and Norman Virus Control 5.90
Live OneCare was the lowest scorer, with 99.91%
