Malicious Android apps with Clicker malware have been spotted by cybersecurity researchers, as 16 apps with 20 million downloads were on the Google Play Store — and they can drain your phone's battery life.

Discovered by McAfee Mobile Security, researchers found that malicious code snuck its way into a number of utility apps, which threat actors often use to trick users into downloading. These include apps such as QR readers, flashlights, unit converters, task managers, and more.

This led to around 20 million downloads, with the apps hiding ad fraud features so attackers can make a profit without the user's knowledge. This is done through a clicker trojan, which continuously makes connections to websites and generates revenue through fake clicks on pay-per-click bases.

As McAfee's security team points out, "Mainly, it is visiting websites which are delivered by FCM message and browsing them successively in the background while mimicking user’s behavior." Unfortunately, this will cause heavy data usage and will even drain your device's battery right under the user's nose — all for the threat actor to make some cash.

For those who have noticed their phone's battery life isn't as long as it used to be, it could be due to these apps. 

Delete these apps 

While McAfee has already notified Google of the malicious apps and are no longer available on Google Play, that doesn't mean they may not be installed on your phone. It's a good idea to delete the Android apps listed below, especially if it will boost your smartphone's battery life and performance.

This includes a knock-off WhatsApp on Android that uses malware to steal your account, along with malware-infested Android apps stealing money.
