Nice review from Digitaltrends.com of top Android security apps. And the winner is: avast! Free Mobile Security!
I love this quote: "if you do want to go ahead and get an Android security app, Avast is your best bet".
The author of the review - Simon Hill - is at the end asking a (rhetorical) question that we might introduce a fee for the product. Well, this is certainly not going to happen. avast! Free Mobile Security will continue to be offered loaded with features and for free. Just priceless ;)
