Malware is out to get you. It’s a sad and unfortunate truth: regardless of your device, becoming infected with malware is a very real possibility when software installation is involved. For a long time, malware was isolated to Windows due to its dominance in the computer market, eventually moving on to infect Mac and Linux computers (to a lesser degree). Now, malware presents a threat to mobile devices, including Android. Are you prepared?

The immediate question is, how does malware get on an Android device in the first place? After all, most users only install apps through the Play Store, and Google keeps a tight watch over that to make sure malware doesn’t squeeze through, right? Not entirely. Suspicious apps have been known to make it onto the Play Store.

Signs of Android Malware Infection


Just as on a computer, there are some warning signs that can alert you to the presence of a malware infection on an Android device. The gist of it is this: if something begins acting out of the ordinary and you haven’t made any significant changes to your device, the problem might be malware related.

  • Unexplained data usage. A lot of malware exists to collect data: account details, credit card numbers, contacts lists, etc. Once it has this information, the malware app needs to relay it back to whoever created that malware – and in most cases, this information transfer will result in strange spikes in data usage.
  • Poor phone performance. Depending on the age of your device and the severity of malware infection, your phone’s performance might take a hit. If you experience a slowing down, you might have a malware infection – especially if a reboot doesn’t alleviate the problem.
  • Reduced battery life. Since most malware are designed to sit in the background and run all day long, you may notice a dip in your battery life. More severe cases of malware will kill your battery faster than mild cases.
  • Dropped phone calls. Sometimes your calls will drop due to poor service. Other times, the culprit could be malware interference. Most of the time, poor service will be the right answer, but when you start dropping more calls than normal, it could be indicative of malware.

Keeping Your Android Free of Malware


The only way to completely prevent malware on your Android is to never download any apps, never plug the Android into a computer, and pretty much live in a bubble for the remainder of the device’s lifetime. Well, that’s not exactly practical, so here are some tips you should know to minimize the chances of contracting malware.

  • Check app reviews. When you find a new app to download, always read the reviews first. If the app is problematic in any way, some of the reviews will make note of it and you can move on. If the app doesn’t have any reviews, you may want to steer clear until it does.
  • Check developer’s track record. Okay, so let’s say there’s an app you really want but there are no reviews on it and you don’t feel like waiting. You can always check the developer’s other apps to see if they have a reputable track record. If this is their first app, though, you’re back to square one and your best bet is to be safe than sorry.
  • Be wary of third-party app markets. The truth is, all app markets have some degree of risk to them. If the Play Store can let slip a few malware apps, then it’s safe to assume that no app markets are completely safe. At the very least, stick to the reputable ones like the Amazon Appstore How To Install & Use The Amazon Appstore To Get Awesome Free Apps!

  • Be careful when granting Superuser privileges. For those of you who have rooted your Android devices, make sure you limit Superuser privileges only to the apps you trust 100%. If you grant Superuser access to every app that asks for it, then you’re just asking for malware to gain full control of your device.
  • Run malware scans regularly. This shouldn’t be a problem if you installed one of the apps above since they all have the ability to schedule scans. But whatever you choose to use, be sure to make a routine out of scanning, whether it’s once a day or once a week.


Now, with all of that said, don’t freak out. Many happy Android users have gone years without ever contracting malware, so it’s not like you’ll find it around every corner just waiting to jump you. However, it’s always good to be prudent when it comes to security and it’s better to know about it than bumble along in ignorance. Take heed and keep your Android device safe!
