Some people will tell you that an Android phone is safe from computer viruses. But over the summer, dozens of apps containing adware and malware were found on the Google Play Store (, 26/07/2022). Google Play Protect can tell you if your app differs in any way from the version it maintains in the Store. But what if the original Google-approved code was bad?

Obviously, there is a role for anti-malware apps that can scan an Android phone for viruses and other malware. Many products available for Android devices come from the same companies that have been protecting PCs for years. But once any current infestation is removed, there are still future threats to consider. Let’s assemble the components of a successful Android security strategy.

To scan an Android phone for viruses and malware, download a reputable anti-malware app (see our link above for a list) from the Google Play Store and have it scan your phone for viruses. suspicious code. After the scan, go through your app list and remove any app you don’t remember installing.


Can Android phones be infected with viruses or malware?

A virus is a special type of malware that behaves in a specific way. It duplicates itself in the operating system or application code, in the same way that a biological virus inserts its genetic code into human cells. Although Android phones do not usually contract this particular type of security threat, there are other forms of malware (the broadest category that contains viruses and other malicious code) that can achieve the same goals as those of the creators of a virus: getting your information, damaging your phone or holding it for ransom.

Android phones usually acquire malware through the owner of the phone who is tricked into downloading it. It can come from a downloaded app, an attachment to an email or text message, or content downloaded from a website. It could even be from another phone if you connect the two together.
If your phone is slowing down, burning its battery very quickly, or constantly rebooting, it could be caused by malware. If the same app starts crashing repeatedly, if you see ads popping up in apps that normally don’t have them, if your phone suddenly starts to overheat, or if you see an app on your phone that you can’t remember installed, you probably have an unwanted guest in your phone. So what should you do?

How to Scan for Viruses or Malware on Android

The first thing you need to do is scan your Android phone for malware. There are a multitude of anti-malware applications for the Android operating system. Most operate on the same model of offering a free version with basic features and charging for the deluxe version. Most Android owners will be fine with the free version (e.g. many people don’t want a VPN). These applications are very easy to use, most having a large To analyse button when you open the app. Of the apps listed in our linked article above, Bitdefender Free is an excellent choice. It’s lightweight and offers decent functionality in its freeform incarnation. When you download Bitdefender Free and open it, this is what you will see.

Now that we’ve determined that your phone is currently not infected, we need to cover the possibility that there is a corrupt app on your phone that just hasn’t moved yet. If there’s an app on your phone that you haven’t downloaded from the Google Play Store, it’s unfortunately suspicious as the default position because apps aren’t usually available in the Google Play Store for some reason.

Sometimes it’s because an app is performing a function that violates a company’s terms of service. And sometimes it is because the makers or distributors of the app want to put spyware or other malware in their app. They know Google won’t allow it. Although there are sometimes temporarily infected apps in the store, Google regularly scans their stock to remove malware. If you want to be sure that your device is safe, remove any apps from your phone or tablet that you haven’t downloaded from the Google Play Store.

What about the future?

Keeping your Android device free of malware in the future is a matter of vigilance. Here are some steps you can take to ensure that no malicious code finds a beachhead in your phone:

  • Continue to take all the normal security measures you’ve probably become accustomed to, including never clicking on links in emails or text messages unless you’re 100% sure they’re safe, and lock your phone with a PIN when you’re not using it. for a certain time.
  • You can use an antivirus application on your device. For real-time protection, consider a monthly subscription. That said, antivirus software on a PC is pretty much a necessity. With Android, if you follow basic security practices like not opening suspicious messages and emails, avoiding third-party apps outside of Play Store, and other similar precautions, you may find that a antivirus software is not necessary for all users.
  • Google Play Protect is a feature of the Google Play Store that can scan the Play Store apps you have on your phone or tablet and compare them to store versions. Any modified application on your device will be reported. If you only use Play Store apps and scan regularly with Play Protect, it will be difficult for anyone to corrupt your device. Search Play Protect in the Play Store to access the tool.
  • Each Android system update includes security fixes and fixes for known vulnerabilities in the previous version. The longer a version of Android has been available to the public, the greater the chance that someone could exploit these vulnerabilities, as more hackers discover them. Between version updates, there are also smaller Android security updates. You should install them as soon as they are offered.
  • Disable password saving. It makes a hacker’s job much easier when your passwords are stored on the very device they’re trying to invade.

All viruses are malware, but not all malware is a virus. A virus is a type of malware that spreads by copying itself into your phone’s operating system or application code. Malware can be a virus, ransomware, adware, or worm. Viruses are a subset of all malware.

Androids do. There are more Android phones in the world than iPhones, so they are a more attractive target for malware makers. There are also more possibilities to infect an Android because you can download Android apps from places other than the Google Play Store. This gives bad actors a way to bypass Google Play Protect and gain access to your device. The only way to download an app on an iPhone that isn’t from the Apple Store, with its vaunted security procedures, is to jailbreak the phone.

No. It is very difficult to corrupt an Android phone to the point of having to throw it away. If your phone is extremely infected, you can always factory reset it and start fresh.

Clicking on links in text messages can lead you to malicious websites. And hackers can even use Bluetooth to push virus-infected files that an unsuspecting person could open.
