A little over a week after Kaspersky's anti-virus software declared Windows Explorer was a virus, it appears that McAfee has had its own mistake, a flawed DAT file or virus definition got pushed out causing many user to get bogus warnings that several popular websites like Friendster, Ars Technica, Verizon Wireless, ESPN and others are running a malicious code.
It seems that the latest batch of virus definitions – version 5197 - for the signature-based AV McAfee VirusScan hadn't had quite enough testing, and was rolled out with a flaw giving the scanner a hair-trigger when checking websites on-the-fly. Users of the software will have had trouble accessing not-inconsiderable chunks of the web since installing the update, which is performed automatically at regular intervals without prompting the user.
Users affected by the bug are recommended to upgrade to DAT file version 5198 or newer, which will be done automatically at the next scheduled check.
