Anti-virus struggles on 64-bit Vista

Anti virus software for the 64-bit version of Windows Vista is struggling to properly protect the operating system, according to a new test by the Virus Bulletin security certification body.

Of the 20 anti-virus product tested, 35 per cent failed to meet the test’s criteria. Six of the failing grades were caused by so called false positives, legitimate files that are incorrectly flagged as malware.

Of the major vendors, McAfee Virusscan and Symantec Antivirus both passed the test, as did Microsoft’s Forefront, Redmond’s enterprise grade security suite that was released last May.

CA’s eTrust application failed the test. The software comes with improper default settings that instruct the software to ignore many file formats. It therefore failed to detect many malware applications. Users instead have to manually apply the proper settings.

Trend Micro submitted three products for testing, all of which mistook a Microsoft development tool for malware.
