How to Get Rid of (Delete) Android Viruses?

Android is a very flexible operating system. Compared to competing platforms like iOS and Windows Phone, it gives more freedom of action to the user, but this evident advantage means taking some more risks about informatics safety.

The opportunity to install apps from external sources, “outside” the Google Play Store, and the pretty wide spread of the operating system (it’s the most used platform in the world, as regards smartphones) has meant that Android attracted some unpleasant attentions from cybercriminals, who create malwares aimed to spy the users’ activities, collecting their data and sometimes activating some very expensive premium services by SMS.

To protect yourself from this kind of risk, you need to use your own smartphone/tablet wisely, avoiding downloads of apps from external sources (but it must be said that sometimes, viruses have been found even on the Play Store, disguised as innocuous games or apps) and, if possible, installing a good antivirus: there are many of them, even for free, without slowing the system down at all, and getting to guarantee a great level of protection. If you want, I can suggest you some of the best ones around and teach you how to delete Android viruses by using them. It won’t take long, I promise.

How to prevent malwares installation on Android

Before we take a look to the best antimalware apps currently available on Android, let’s clear up an important point: to reasonably rest easy, you should just download apps from safe sources only, so from the Play Store only, from developers with proven reliability, and don’t root the Android system.  (Read More: How to Root Android Phone)

Therefore, as a default setting, most of Android smartphones and tablets don’t have the root permissions enabled, and don’t allow you to install apps from different sources than Play Store, but to be sure that both of these security measures are active, just check these simple things:

  • Open the list of the apps installed on your smartphone/tablet and see if there’s one called SuperSU or SuperUser among them. If not, your device hasn’t almost certainly been rooted. For a more “serious” check you can install the Root Checker app and find out if your device has root permissions unlocked or not. If your smartphone or tablet results to be unlocked through root, you can “lock” it back by selecting the appropriate entry from the SuperSU or SuperUser app. However, I warn you that doing this, you won’t have the possibility to use apps that needs root permissions enabled to work. More info about this, can be easily found on Google by searching for a specific guide for your device (for example: “How to remove root from Samsung Galaxy S7”)
  • Go to the Android Settings, select the Security entry from the menu and check if the Unknown sources is enabled. If yes, disable it and then the installation of apps from external sources will be blocked automatically.

Unknown sources

Now you have a reasonably safe-to-use device but, beware, not immune from the malwares risk. If you want to rest even more easy, you must install an antivirus like the ones I’m going to suggest you, but knowing that you’ll have to renounce to a bit of memory and/or performances to make the software control the system in real time. Have fun!

Avast

Avast

An Android antivirus that I highly suggest you to try is Avast, which includes an antimalware protection with real time scan of recently installed apps on the device, finds the apps that are most dangerous for privacy, blocks unwanted calls, blocks the access to the apps through a password and allows to find the device if it gets lost or stolen.

To install Avira for Android, search for it in the Play Store and tap the Install and Accept buttons. Then open the app, tap on Continue and run the first antimalware scan of your smartphone/tablet by pressing the Analyse this device button.

Besides this thing, there’s not really much more to explain,  Its interface is extremely easily understood: by selecting the Smart Scan option from the main menu and pressing the Analyse this device button, you can run a new on-demand scan of the system; by selecting the Check Wi-Fi entry you can test the security level of the wi-fi network you’re connected to, while by going to the Settings section you can find all the “extra” information about Avast.

Among the “extra” features of Avast you can find: Block app, to block apps with a password; Privacy Advisor, to find out which apps are more risky for your privacy; Block calls, to block unwanted calls and Firewall, to regulate the access to internet connection for the apps. In the end, I remind you that by going to the Other Avast products and Storage sections of Avast, you can find links to more free apps that Avast realized for Android, such as Anti-theft and the system cleaning app Avast Cleanup.

Bitdefender

Bitdefender

The Android version of Bitdefender gives always great results in comparative tests, but unfortunately its free version offers only a very few functions compared to the competing apps: it lets you run on-demand scans of the system, monitor newly installed apps, but doesn’t have any anti-theft feature, can’t block unwanted calls and doesn’t allow to deny the access to the apps you want to keep private.

To install the free version of Bitdefender on your smartphone/tablet, search for Bitdefender Antivirus Free on the Google Play Store and tap the Install and I Accept buttons.

Eset Mobile Security

Eset Mobile Security 

Another Android antivirus that I want to suggest you is Eset Mobile Security, which unfortunately, just like Bitdefender, offers a pretty limited number of features in its free version.

The free version gives the opportunity to run a complete scan of the system, examine recently installed apps automatically, but doesn’t update the antimalware definitions in real time; it includes an anti-theft function (more limited than the pro version) but doesn’t filter unwanted calls, see which are the more privacy-risky apps, or block phishing attempts. You can find the premium version of this app for just s 30 days period, then it costs 6.95€ per year.

To download the free version of Eset on you smartphone or tablet, open the Play Store, search for it there and tap the Install and I accept buttons. After that, run the app, set your language to Italian and tap I accept to run its startup setting configuration process.

Then, put the check next to the I want to join Eset Live Grid entry, to benefit of the cloud protection of Eset, go ahead and select the Enable detection option from the drop down menu in the middle of the screen, to activate protection against potentially dangerous apps (not actually considered as “malwares” yet in the definitions, but still suspicious).

In the end, choose whether to try the free versions of Eset right away or activate the free trial of Eset Pro, and wait for your smartphone/tablet’s full scan to be completed. Then, the app will provide to monitor the system in real time.

Avira Antivirus Security

Avira Antivirus Security

Avira Antivirus Security hasn’t really did that good in the last comparative tests, but it gets to guarantee a great level of protection anyway, without slowing the system down that much. It’s free but includes some functions that could be unlocked only by registering to Avira’s online services, or upgrading to Avira Security Pro, that costs 11.99$ per year.

Features offered in the free version are those related to the antimalware protection (with on-demand scan and automatic control over recently installed apps on the device), the block for unwanted calls and the detection of the apps that could be risky for the privacy. Who created a free account on Avira’s online services can, moreover, benefit of the anti-theft function in order to find the smartphone in remote, of the anti-phishing protection and block the apps through a password.

Kaspersky

Kaspersky

Finally, I want to spot you Kaspersky Internet Security, another very appreciated antivirus that offers lots of interesting features: antimalware scan (with real time protection for premium users only), incoming calls filter, and anti-theft. Web protection, abti-phishing filter and private contacts,text and calls concealment are only available for users who buy the premium version, which costs 14,95$ per year, but you can try it for free for a 30 days period.

In the end, tap the Run the scan button and wait for the results of the system check. All of the features of the app are available from its main menu, which appears by pressing the arrow at the bottom-right.
