well i over course do not use macafee or any anti-virus app on any of my android devices, so i'm good there.
and i stopped reading when the article's 1st suggestion was to use a good anti-virus softaware for android. if you click on their suggestions for the best anti-virus software to use, the 1st listing was Norton. Norton is crap and i would never use their products. and i stopped right there, no need to read further.
the key really is never use an anti-virus app on android. and use common sense and you should be fine.
its good to know that there is a trojan out there masquerading as a Macafee app, however.
