I started using MSE because of a story here on Slashdot talking about a review of a large number of antivirus products and I was amazed to see people on Slashdot putting their trust in a Microsoft product.

I've been a hater of Microsoft for a long time now thanks to all the anti-competitive and backstabbing stories I've heard but also because of using their various products. And yet now that I've been using MSE I've turned a corner and started to recommend it to friends and family.

I casually help fix computers for people that know me, sometimes going so far as to do it all over the phone when someone lives too far to visit. At first I tended to browse through their machine looking for the troublemakers and then after finding everything I could I would install and run MSE only to watch it detect and clean 100% of the things I had found and even some I had not, like a trojan hiding in the MBR. I've watched it catch different varieties of the TDSS rootkits, clean up all manner of other nasties and only once have I seen it make a mistake, with Chrome being reported as a virus. Yet, even with that flaw Microsoft had detected the issue and it was on the "More Information" page and had been fixed later that night. Since then I've come to trust MSE to do it's job well and I've started to run it first then clean up afterwords and it hasn't let me down yet.

If Microsoft wants to provide a built in antivirus with Win8 but allows it to be disabled to run other things, just like Windows Firewall, then I am all for it. I would do almost anything to keep people from installing the nightmares that are Norton & McAffee (and these days sadly Zone Alarm Antivirus). I've watched both those powerhouse antivirus programs completely miss fake antivirus programs that sneak through Facebook and in Nortons case it turned a simple "Safe Mode/Delete/Remove Registry Startup Command" into a three day slog that only worked when I finally got mad an uninstalled Norton from the machine.

Microsoft might still make some majorly boneheaded decisions but providing a built in antivirus does not seem to be one of them.
