Every now and then an antivirus company releases a definition update which brings Windows to its knees. ( Example: When Webroot recently released an update which locked people out of their windows 8 machines) The AV accidentally flags a crucial system file as malicious and deletes it. How does this happen? I realize there are 100,000’s of thousands of different windows applications which could accidentally be flagged, thus they can’t test each one, but windows?
I don’t know how they check each definition update, but to me it doesn’t sound that hard. Wouldn’t it be easy to setup a few quad core machines with 2+ SSD’s in raid 0. Then each computer would contain a different bare-bones version of windows, starting with a machine that has all the latest updates. Then before the update is released they scan each machine. Because the computer is a bare install and because it’s running on an SSD raid 0 setup, the scan should only take a few minutes. If they did this before they released each update I don’t see how they could accidentally release an update that kills thousands of machines.
That's just my 2 cents.
When I said Service pack 2 I meant to say Service pack 3!
