How to Treat Virus and Malware Infection on Android Devices


Just recently I had a taste of what you would want to describe as “android virus.” Well my Android phone started pooping up annoying ads which interfered with my activities around the phone. The most annoying part was that my phones data connection turned on and off at will.

The case was actually a result of an adware my phone had contacted from some badly infected websites I visited. The default browser app on my Android smart phone was always opening in a new tab and that was the big deal.

So if you have similar issues or android virus infection problem of any kind, this post will show you how to deal with it correctly.

How to Treat Malware Infection on Android

If your android phone is experiencing any of these symptoms, it means that your device is infected and you can use any of these methods to clean up the infected device.

Method 1

The first and best method is to hard reset your Android phone from the SETTINGS menu. But often times, this may not work because the adware may be installed on your memory card which means you will also need to format your memory card.

Note that formatting your card means you have to delete everything. If you must back up your files then you should only copy those folders you created or the ones with popular names else you may end up backing up a malware.

The most effective way to factory reset your Android device without loosing important data is to connect it to a PC with an up_to_date anti-virus program (Kaspersky recommended) and do a comprehensive backup using dedicated Android PC suits such as  Moborobo or Wondershare MobileGo.

Then format the device completely by Navigating to settings ==> backup and reset ==> factory data reset. Reconnect your device once the factory reset is completed and restore the previously backed up data.

Note that the Anti-Virus program on the PC would normally scan the back-up files, so you will need remove and scan your memory card differently before connecting it back to the mobile device.

Method 2

The second method will not clean the infected device but will prevent the effects of the infection. You may need to repeat these sometimes to make sure that all is well. You should use this method if you don’t want to lose any files.

So, boot your android phone into safe mode. In most devices you do this by holding the power button and when the TURN OFF screen appears you just tap and hold TURN OFF or POWER OFF- depending on what your phone calls it.

After your phone boots into SAFE MODE just navigate to SETTINGS >APPS > DOWNLOADS then uninstall or FORCE STOP any app you didn’t download or install yourself. Also disable background data for any app you couldn’t uninstall probably because your phone is not rooted.

The only thing you can do is to FORCE STOP those apps.
In my case, I had to also FORCE STOP my pre installed Android browser since it was the main carrier of the virus.

Method 3

Install CM security and/or any other trusted anti-malware app to effectively detect and fight malicious codes and vulnerable apps that manages to find its way to your android device.

CM security app would normally detect privacy loop-holes and effectively blocks hijackers and malicious snoopers that may want to tamper with the proper functioning of your devices.

Most security apps works best on rooted devices (see how to root android) and when they are given a higher level of permission.

So it is best to install security apps from highly trusted app vendors and the ones with a high star rating on the Google play store. This is in a bid to avoid insecure app while fighting virus symptoms on your Android devices.

  1. “I always think about with metered data plans, how auto playing ads/videos affect that. For instance, a cursory search of google says that the limit for flash and html5 is 150KB. A Verizon plan is roughly $15.00/GB so you are paying about two tenths of a cent to view the ad every time one of those stupid things shows up (if my pre-coffee math is correct!).

    I would like to see a study on normal browsing data usage vs. with an ad blocker over the course of a month and how much you are actually spending to view the ads. Except on Ars of course! Maybe I am out of my mind and it amounts to nothing.

    Edit: I should have prefaced that saying that I travel quite a bit for work and I’m tethered often. So this probably doesn’t affect the majority of users out there who are only on mobile.”
