McAfee Apologizes for Update Fiasco

McAfee on Thursday issued an apology for the faulty update that shut down users' computers and prompted a continuous reboot cycle.

"McAfee team members have been working around the clock to fix the problem and work with impacted customers," Barry McPherson, executive vice president of worldwide technical support and customer service for McAfee, wrote in a blog post. "We estimate that the majority of the affected systems are back up and running at this time and more systems are coming back online quickly."

The faulty signature update DAT file, which went out on Wednesday, affected the svchost.exe file on "a subset of systems" using McAfee VirusScan Enterprise on Windows XP service pack 3. Users with VirusScan Enterprise 8.7 were hit a bit harder than those running version 8.5, McAfee said, "because of the different implementation of memory scanning within the products."

Other versions of XP, Vista, and Windows 7 were not affected, the company said.

The problem resulted in blue screens, loss of network connectivity, inability to use USB, and continuous reboots, McAfee said.
