McAfee Dat Update Broke Customer Endpoints

Whoops. Antivirus worked even less than usual yesterday when a dat file update to the McAfee Antivirus product broke the application and in many instances, caused connections to the Internet and network to fail completely.

From SC Mag here:

McAfee customers had internet access severed and were left exposed to malware after the company issued a glitched anti-virus update.

The update affected all Windows McAfee suites and VirusScan products including the latest version of VirusScan Enterprise and McAfee Security Center.

Anti-virus signature updates (DAT 6807, 6808) would disable the anti-virus clients, and in some cases sever internet access.

McAfee overnight issued an enterprise 100Mb Super DAT (Hotfix 793640) and a consumer fix (DAT 6809) for the borked updates which it rated as ‘critical’.

Enterprise customers had to apply the hotfix as a product update through the e-policy orchestrator, while consumers were advised to remove McAfee from affected machines and re-install the product in order for the fix to be applied.

Furious enterprise and business customers posted comments yesterday on the McAfee blog claiming they were left high and dry after thousands of machines within their companies were left exposed by the updates.

“I currently have over 3000 endpoints with this problem – solution ASAP please McAfee,” customer Derosa wrote.

Wow, a dat update destroyed the software to the point it had to be reinstalled? And the “SuperDat” is 100 MB in size?? What the hell is in that thing? A playable copy of Doom 2?
