Looks like ad-supported software is now considered malware ...
... by security firms trying to sell something.
I've still yet to see anybody quoting actual infections of real malware from any of the "official" apps stores.
Reminds me of the "sky is falling" approach taken by many so-called security experts when 1 (that's right, 1) infection made it onto OSX machines.
I'll take all of these reports with a large grain of salt until I hear about actual infections of real malware. But I'm not holding my breath.
