As many as 1 million users have downloaded a game on their smartphone or tablet that contains serious malware. Even if you delete the app, it can reinfect your gadget.
According to a blog post by security systems analyst CheckPoint, this malware is highly sophisticated and was able to get past Google's strict malware detection protocol not once, but twice between August and September 15.
The apps is called BrainTest. Since late last month, the infected version of BrainTest has already been downloaded on anywhere from 200,000 to one million devices.
Once you download it, it installs a rootkit on your gadget, which gives hackers full control to download and run any other apps or code they want. That means they can steal your information, show you unwanted ads or use your phone's systems to send spam.
There hasn't been an official patch or any word from Google, but if you're one of the unlucky ones with BrainTest on your gadget just hang tight. We'll keep you up to date with any news about patches or updates for your vulnerable Android.
