The Register is reporting that 17 of the 37 anti-virus packages tested have failed VB100 certification.
McAfee VirusScan, Trend Micro Internet Security and Sophos Anti-Virus overlooked threats known to be in circulation.
I figured since there are a number of Vista users in our community that they may be interested in knowing if their A/V software is actually doing a good job of locking things down and catching known threats.
