Understand what malware is

Understanding Malware Types

Malware is malicious software that compromises the functionality of your devices, damages your files, and interferes with your privacy. These programs come in different forms, which are spyware, ransomware, adware, worms, Trojans, and viruses.

  • Spyware: This quietly monitors your device activity and steals your personal information.
  • Ransomware: This type of malware holds your device or data hostage and demands payment for its release.
  • Adware: It inundates your device with unwanted ads.
  • Worms: These replicate from device to device, causing damage to a network of devices.
  • Trojans: These are malware disguised as legitimate software.
  • Viruses: These attach themselves to clean files and spread throughout your device’s system, causing widespread harm.

How does Malware infiltrate your Android device?

The most common method through which malware infiltrates your device is via downloads and installations from unsecure sources. Some Android apps, especially those from third-party app stores, contain malicious code. Additionally, clicking on phishing emails or malicious ads, browsing unsecured websites, and connecting to insecure public Wi-Fi networks can also expose your device to malware.

Effective Malware Removal

Removing malware from your Android device involves a series of steps:

  1. First, switch your device to safe mode. This prevents third-party apps, including malware, from running.
  2. Go through your list of apps in the settings of your device. If you see any unfamiliar apps, especially ones that you didn’t download, uninstall them.
  3. If the problem persists, consider performing a factory reset on your device. This completely wipes your device and can remove deeply embedded malware. However, remember to back-up any important files before taking this step.
  4. In the future, guard against malware by only downloading apps from the Google Play Store, keep your device’s software updated, and consider installing a reputable antivirus app on your device.

Identifying Malware-induced Behaviors in Android Devices

To fully deal with malware in your Android device, you must first be aware of the common signs that indicate that your device may be infected. These signs include unexpected battery drains, increased data usage, and frequent pop-up ads.

Unexpected battery drains can be caused by malware running background processes, therefore consuming the device’s resources even when you’re not actively using it. If you notice that your battery life is decreasing faster than usual, it could potentially be a sign that your device is infected with malware.

Another sign of potential malware infection is a sudden increase in data usage. Malware may use the device’s internet connection to communicate with external servers, which can significantly increase data usage. In your Android device, you can check your data usage in the device’s settings.

Frequent pop-up ads are another symptom of a possible malware infection. While these ads can appear due to a variety of reasons, if they’re appearing very frequently—especially if they appear when you’re not even using the device—it could indicate that your device has been infected.

Tip: Always be vigilant about sensorim device behaviours and if you notice any of these signs, it is recommended to take necessary actions against it to redress the issue and protect your device.

Identifying Unusual Activities in Android Device

You should also be on the lookout for any other unusual behaviors that might hint at a malware infection. This could include:

Apps crashing: Malware can sometimes cause apps on your device to crash inexplicably.
Unfamiliar apps: If you see apps on your device that you don’t remember downloading, they might’ve been installed by malware.
Slow performance: Sluggish device performance might be caused by malware consuming too many of your device’s resources.
Unwanted Commercials: Unwanted popups or intrusive ads that are difficult to close.

When in doubt, it’s best to take the steps necessary for malware removal in order to protect your private information and keep your device running smoothly. Remember, identifying unusual behaviors in your device is the first step to take towards removing malware. Always be vigilant about protecting your device from threats, and take action as soon as you suspect something amiss.

Learn about Android in-built security features

Activate and Use Default Security Features on Your Android Device

Android devices inherently come with built-in security features designed to fend off malware. To use these features effectively, you need to activate them first. To do this, navigate to the settings app on your Android device. In the settings menu, tap on the “Security” or “Security & Privacy” option.

Inside the “Security & Privacy” section, you’ll find multiple options related to your device’s security. One of these options should be “Google Play Protect.” This feature scans your device for malicious apps regularly and alerts you when it detects malware. Make sure the ‘Scan Device for Security Threats’ option is turned on.

Also, within the Security section, look for an option called “Unknown sources” or “Install unknown apps”. This feature directly impacts which apps you can install onto your device – only allowing installations from the Google Play store by default, which contains more secure, vetted applications. Make sure this is turned off to prevent unverified app installations, which often carry malware.

Regularly Update Your Android Device

Keep your Android device updated. Outdated software can be exploited by malware. To check for updates, head back to the settings menu, scroll down, and tap on “System,” then “Advanced,” and then “System update.” If an update is available, your device will guide you through the installation process.

Download Apps from Secure Sources Only

Even though Google Play Store has numerous security measures in place to scan apps for malware, some malicious apps can still bypass this security layer. Thus, it’s essential to download apps from well-known developers only and always check the app’s review and rating before installation.

Install a Reliable Antivirus App

While Android’s built-in security features offer a good layer of protection against malware, extra layers of security can be beneficial. Thus, consider installing a reliable antivirus app from the Google Play Store. Brands like Norton, McAfee, and Kaspersky offer excellent options. These apps can provide real-time protection against malware, automatically scanning your device regularly to ensure it remains clean and secure.

Regularly Review Your Apps and Permissions

Finally, regularly review the apps installed on your device and the permissions they have. Look out for any suspicious apps you don’t recognize or any apps with unnecessary permissions. To do this, go to “Settings”, then “Apps & Notifications”, and then “See all apps”. Tap on an app to see its permissions, and remove any apps that have unnecessary or dubious permissions.

Master the process of removing malware from Android

Starting Your Device in Safe Mode

To effectively remove malware from your Android device, it is essential to start your device in Safe Mode. This mode allows you to use your phone without any third-party apps running, which means any malware-infected apps will not be operational. To activate safe mode, press and hold the power button on your device until the power off/restart menu appears. Press and hold the power off option; this should prompt the option to reboot in safe mode. When your phone restarts, it’ll be in safe mode.

Note: It's worth to mention that steps required to start android device in safe mode may vary depending upon brands and android versions.

Identifying the Malicious App

Now that your Android device is in Safe Mode, the malicious app needs to be identified. In many cases, the malware takes the form of an app that was recently installed. To spot the suspicious app, navigate to your phone settings, and then to the Apps/Application Manager. Look through the list of the apps installed on your device. Although the malware could carry the name of any app, connections with recent unexpected behavior from your phone should give you some clues.

Uninstalling the Malicious App

The next step is to uninstall the problematic app. In the Apps/Application Manager, click on the suspicious app and then hit the ‘Uninstall’ button. If the uninstall button is grayed out, that could be a sign that the app has been given administrative controls. If this is the case, go to the ‘Settings’ and then ‘Security’, then to ‘Device Administrators’, where you can easily revoke these privileges from the misbehaving app. After this, you should be able to hit ‘Uninstall’ and permanently remove the app from your device.

Validating the Removal

The final step is to validate the removal and ensure your phone is completely malware-free. Check the list in your Apps/Application Manager once more to ensure the app is gone. Additionally, it’s a good habit to install a credible antivirus app from Google Play Store and perform a full scan of your device. These apps are generally capable of identifying and alerting any remaining or new threats. Remember to also switch out of Safe Mode to return to normal device operation.

Regular Malware Protection

Regularly updating your device’s software can also keep malware at bay. Often, these updates include fixes for any known security issues. Installing apps from trusted sources, like the Google Play Store, can also help prevent malware infections. Always be cautious of the permissions that new apps request upon installation, especially when they ask for administrative privileges. Following such precautions can help avoid the hassle of having to remove malware from your Android device.


Developing a comprehensive knowledge of malware is paramount to ensuring the longevity and secured performance of your Android device. This involves recognizing the signs of a compromised system and learning how to activate and use Android’s inherent security features. Valuable skills such as starting your device in safe mode, pinpointing the malicious application, safely uninstalling it and confirming its successful removal are crucial in the battle against intrusive software.
