McAfee DAT Causes Windows Computers to Shutdown

Wednesday McAfee pushed a DAT file update to it’s enterprise customers that made the software think that a Windows file was a virus. This caused the computers to go into a continual reboot loop.

If you remove the computer from the network and log in as the local admin you can install the patch because the DAT doesn’t see the network EPO agent to talk to. Once the patch is applied you can reconnect to the network.

Fortunately this doesn’t corrupt Windows, so it is just an annoyance. But the question that should be asked is why wasn’t this tested properly? For such a big company with many important enterprise customers you would think that DAT files would not think a needed Windows file would be a virus.

How do we prevent this? What are possible solutions?
