How is this news? From the very beginning the entire point was that it was a free antivirus in a day and age where the average
idiot person wasn't running any form of antivirus. It wasn't ever meant to be the best antivirus you could possibly get, it was only meant to be a pretty decent one for people who couldn't afford one. Now it's built into Windows, and it does a good enough job that I don't feel the need to install a 3rd party antivirus.
