Hey, lighten up. It's technical satire.
The thing about humor is that most jokes are only funny the first time.
This is about the 20th time I've been exposed to this particular one, be it the "MS Antispyware removes Internet Explorer!" or the "MS Antispyware removes Mozilla Firefox!" varieties. Heck, Slashdot today put up a Photoshopped MS Antispyware results screen that turned up Firefox as a high-level spyware risk--and they thought it was serious.
And you didn't put a satire alert in the header, so now some people will actually believe this. You'll have to forgive me if I'm not laughing.
