Now, do you remember that infamous blog post where some guy Mike trash-talked Microsoft Security Essentials on behalf of Symantec?
(NOTE. I will not let this go until that shameful post gets removed)
Now look what I got, a new Retrospective/Proactive test by AV-Comparatives, a reputable testing firm, wouldn't you agree?

Now, how do you like them apples??
Lesson & moral of this story? Please, do not trash-talk your competition just because they are free and they are Microsoft. It is not nice, and sooner or later it'll bite you in your behind.
