An Ars forum member by the name of adminfoo recently installed Microsoft Security Essentials (MSE) to see what all the fuss was about. To his surprise, the security solution quickly labeled him as a malware author. MSE apparently was not quite happy with a .VBS script he had written, and so he decided to dig deeper. His analysis prompted us to do some digging of our own.
After investigating, we've come to a few conclusions: this is a false positive (a file or program that is not dangerous but is detected as such), Microsoft needs to be much quicker to react to false positives (though this is the first one we've seen trip MSE up), and the company's new consumer solution is a much more complicated piece of software than most believe.
