Google has presented the boot to 9 Android apps downloaded far more than 5.8 million occasions from the company’s Play marketplace immediately after researchers explained these applications made use of a sneaky way to steal users’ Facebook login qualifications.

In a bid to acquire users’ believe in and reduce their guard, the applications provided thoroughly functioning expert services for photo editing and framing, physical exercise and instruction, horoscopes, and removal of junk information from Android gadgets, according to a write-up released by protection organization Dr. Net. All of the discovered apps presented users an option to disable in-application advertisements by logging into their Fb accounts.

The offering from Malwarebytes is my favorite.
