Oopsy-daisy! According to complaints on McAfee's message board, a mandatory service pack for the company's antivirus VSE 8.7 software has left some machines unbootable. The update, which was issued on May 27 and later pulled on June 2, was intended to squash minor security bugs, but also inadvertently flagged some Windows system files as malware.
"McAfee removed Patch 1 for McAfee VirusScan Enterprise 8.7i from its download servers out of precaution after a potential issue with the update was discovered," McAfee said in a statement. "A very small number of customers reported trouble with the patch on a limited number of computers."
McAfee went on to say that it's working on identifying the cause of the false positives and, once resolved, will repost the mandatory update.
