Businesses urged to test updates after McAfee glitch
Security professionals have urged organisations to test antivirus updates before live deployment, after a glitched McAfee anti-virus update last week left thousands of machines exposed.
On Monday night, McAfee issued an enterprise 100Mb Super DAT (Hotfix 793640) and a consumer fix (DAT 6809) for the borked updates which it rated as ‘critical’.
The glitched anti-virus signature updates (DAT 6807, 6808) affected Windows McAfee suites and VirusScan products. They disabled the anti-virus clients, and in some cases, severed internet access. 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.
