An antivirus service used by tens of thousands of businesses and millions of home users shut down an untold number of computers around the world after it mistakenly identified core parts of Microsoft Windows as threats, the company confirmed Tuesday.

Yet another fine example of why I have never recommended that software. I tried it some years ago and found it really lacking. Unlike the recent case in which I advise against attempting to use White Canyon software, I posted no warning about Webroot; I merely suggested better alternatives.
At this point, Windows Defender has become robust enough to use as a stand-alone defense system.
