A news was released today about a test by Virus Bulletin. It says that 30% of the most used anti-virus products for the 64-bit version of Microsoft Windows Vista generate false positive results.

John Hawes of Virus Bulletin says, “A false positive can cause as much disruption as a virus infection. False warnings often lead end-users to delete valid files in the belief that they are some form of attack and the resultant damage can be significant.”

The high percentage is due to the Patch Guard technology according to Vista.blorge.com’s article.

Some of the software who passed the test are McAfee Virusscan, Symantec Antivirus, and Microsoft Forefront.
