How To Protect Your Android Device From Malware

Malware is a serious threat to your Android device and your data. Malware can infect your device through malicious apps, links, attachments, or Wi-Fi networks. Malware can steal your information, lock your device, display unwanted ads, spy on your activities, or even use your device to mine cryptocurrency. In this article, you will learn how to detect, remove, and prevent malware on your Android device. You will also find out how to keep your device updated, secure, and backed up. By following these tips, you can protect your Android device from malware and enjoy a safer online experience.

What is Android malware?

Android malware is malicious software that specifically targets Android devices. As with any type of malware, the intention is to harm the user’s device and steal their data. Compared to Apple’s App Store, Google’s Play Store has less rigid security measures in place. In addition, Android users can download apps from various sources on the internet. This creates an environment in which cyberattacks are possible.

How does Android malware work?

Android malware spreads in a variety of ways, including:

Downloading malicious apps:

By far the most common method hackers use to spread malware is through apps and downloads. The apps you download via official stores tend to be safe – although not always – but those that are pirated or downloaded from less legitimate sources are more likely to contain malware. Occasionally an app with malware will make it through to an official app store. These apps are usually discovered and removed quickly, but they underline the need to remain vigilant. If developers use untrusted SDKs – software development kits – then the apps they develop have an increased risk of malware.

Using a device with operating system vulnerabilities:

Hackers can exploit any vulnerabilities within your device. Usually, security vulnerabilities are discovered fairly quickly and patched up, but if you don’t regularly update software, then your device may be vulnerable. As with your computer, it’s essential to keep your mobile device up to date, because hackers can exploit newly discovered vulnerabilities.

Opening clicking on suspicious links in emails or texts:

Compromised emails are another way in which hackers install malware on your phone. For example, you may receive an email that says you have won something (a tablet, a vacation, etc). Or you may open an email that appears to be from your bank or another trusted company, asking you to update your details or login to your account. In both scenarios, if you click on the link, you may be taken to a malicious website that downloads and installs malware on your phone. The data on your phone may then be exposed to the hacker. The same applies to links contained with text messages that appear to come from a legitimate source or even someone in your contact list if their phone has been hacked. If in doubt, avoid clicking on links or opening attachments.

Using non-secure Wi-Fi/URLs:

Public Wi-Fi networks are convenient, but they can also be dangerous. Hackers can set up fake Wi-Fi hotspots or intercept your data on unsecured networks. They can also redirect you to malicious websites or inject malware into your device. To avoid this, you should always use a VPN (virtual private network) when connecting to public Wi-Fi. A VPN encrypts your data and hides your online activity from prying eyes. You should also avoid visiting websites that don’t have HTTPS in their URL, as this indicates that they are not secure.

The most common types of Android malware

There are many types of Android malware, but some of the most common ones are:

Android ransomware:

This type of malware locks your device or encrypts your files and demands a ransom to restore access. Ransomware can be delivered through malicious apps, links, or attachments. Some examples of Android ransomware are Simplocker, DoubleLocker, and WannaLocker.

Android banking Trojans:

These are malware that target your banking and financial information. They can steal your login credentials, intercept your transactions, or display fake screens that trick you into entering your details. Some examples of Android banking Trojans are Anubis, Cerberus, and Ginp.

Android adware:

This type of malware displays unwanted ads on your device, often in the form of pop-ups, banners, or notifications. Adware can be annoying, but it can also be dangerous, as some ads may contain malicious links or code. Some examples of Android adware are GhostPush, Judy, and HummingBad.

Android spyware:

This type of malware monitors your activities, such as your calls, messages, contacts, location, browsing history, or camera. Spyware can be used for various purposes, such as identity theft, blackmail, or stalking. Some examples of Android spyware are Pegasus, Exodus, and Skygofree.

Android rooting malware:

This type of malware gains root access to your device, which means it can bypass the security restrictions and perform any actions. Rooting malware can install other malicious apps, delete or modify your files, or take over your device. Some examples of Android-rooting malware are Godless, Ztorg, and KingRoot.

Android cryptojacking malware:

This type of malware uses your device’s resources to mine cryptocurrency, such as Bitcoin or Monero. Cryptojacking malware can drain your battery, slow down your device, and increase your data usage. Some examples of Android cryptojacking malware are Loapi, HiddenMiner, and Coinhive.

How to detect Android malware

If you suspect that your device may be infected with malware, you should look for the following signs:

  • Your device is slower than usual or crashes frequently
  • Your battery drains faster than normal or overheats
  • You see unexpected charges on your phone bill or online accounts
  • You notice unfamiliar apps or icons on your device
  • You receive strange or unwanted pop-ups, ads, or notifications
  • You experience network or connectivity issues

How to remove Android malware

If you have detected malware on your device, you should take immediate action to remove it. Here are the steps you should follow:

Step 1: Go into Safe Mode.

Safe Mode is a mode in which your device only runs the essential apps and services. This can prevent the malware from running or interfering with your removal process. To enter Safe Mode, press and hold the power button until you see the power menu. Then, press and hold the Power off option until you see the option to reboot into Safe Mode. Tap OK to confirm. You should see a Safe Mode label on the bottom left corner of your screen.

Step 2: Identify the malicious app.

 Once you are in Safe Mode, you should look for the app that is causing the problem. You can do this by checking your app list in Settings > Apps or Application Manager. Look for any apps that you don’t recognize, that have unusual names, or that have excessive permissions. You can also sort the apps by installation date or size to find the suspicious ones. Alternatively, you can use an antivirus app to scan your device and identify the malicious app.

Step 3: Uninstall the malicious app.

After you have found the app that is responsible for the malware, you should uninstall it as soon as possible. To do this, tap on the app in the app list and select Uninstall. If the Uninstall button is grayed out or disabled, it means that the app has administrator access and you need to revoke it first. To do this, go to Settings > Security > Device Administrators and uncheck the app. Then, go back to the app list and uninstall it.

Step 4: Remove administrator access.

If the malware has gained administrator access to your device, you should remove it to prevent it from reinstalling itself or causing further damage. To do this, go to Settings > Security > Device Administrators and uncheck any apps that you don’t trust or need. Be careful not to uncheck the apps that are essential for your device, such as Google Play Services or Find My Device.

Step 5: Restart your device.

After you have removed the malware and its administrator access, you should restart your device to exit Safe Mode and apply the changes. To do this, press and hold the power button and select Restart. Your device should now be free from malware.

How to protect your Android device from malware

Removing malware from your device is not enough. You should also take preventive measures to avoid getting infected again. Here are some tips to help you protect your Android device from malware:

Only download apps from official stores.

The safest way to download apps is from the Google Play Store or other official sources, such as the Samsung Galaxy Store or Amazon Appstore. These stores have security checks and policies to ensure that the apps are safe and legitimate. Avoid downloading apps from third-party marketplaces, websites, or links, as they may contain malware or viruses.

Avoid downloading apps from unknown sources.

Even if you download apps from official stores, you should still be careful about what you install on your device. Some apps may have hidden or malicious features that can harm your device or data. To prevent this, you should avoid downloading apps from unknown sources, which are apps that are not from the official stores. To disable this option, go to Settings > Security > Unknown Sources and turn it off.

Check app permissions and reviews.

Before you install an app, you should check its permissions and reviews. Permissions are the access rights that the app requests to use your device’s features, such as your camera, microphone, contacts, or location. You should only grant permissions that are necessary and relevant to the app’s functionality. For example, a flashlight app does not need to access your contacts or location. If an app asks for too many or suspicious permissions, you should avoid it. You can also check the app’s reviews and ratings to see what other users think about it. Look for any negative or suspicious feedback that may indicate that the app is malicious or buggy.

Update your device and apps regularly.

One of the best ways to protect your device from malware is to keep it updated. Updates often include security patches and bug fixes that can prevent hackers from exploiting any vulnerabilities in your device or apps. To update your device, go to Settings > System > System Update and check for any available updates. To update your apps, go to the Google Play Store tap on the Menu icon > My Apps & Games and check for any updates. You can also enable the auto-update option to update your apps automatically.

Use a VPN when connecting to public Wi-Fi.

Public Wi-Fi networks are convenient, but they can also be dangerous. Hackers can set up fake Wi-Fi hotspots or intercept your data on unsecured networks. They can also redirect you to malicious websites or inject malware into your device. To avoid this, you should always use a VPN (virtual private network) when connecting to public Wi-Fi. A VPN encrypts your data and hides your online activity from prying eyes. You can use a reputable VPN app or service to protect your device and data.

Avoid clicking on suspicious links and attachments.

Another way hackers can infect your device with malware is through phishing. Phishing is a technique that involves sending fake or spoofed emails, texts, or messages that appear to be from a legitimate source, such as your bank, your friend, or a company. The message may ask you to update your details, log in to your account, or claim a prize. If you click on the link or open the attachment, you may be taken to a malicious website or download malware on your device. To avoid this, you should always be wary of any unsolicited or unexpected messages that ask you to do something. You should also check the sender’s address, the message’s tone and grammar, and the link’s URL before clicking on anything. If you are not sure, you can contact the sender directly or verify the information from another source.

Encrypt your device and use a strong password.

Encryption is a process that scrambles your data and makes it unreadable to anyone who does not have the key to decrypt it. Encryption can protect your device and data in case it is lost, stolen, or hacked. To encrypt your device, go to Settings > Security > Encrypt Device and follow the instructions. You will need to set a strong password or PIN to unlock your device after encryption. You should also use a strong password or biometric authentication to lock your device and apps. A strong password is long, complex, and unique. It should include a combination of letters, numbers, symbols, and cases. It should also not be easy to guess or relate to your personal information. You should also change your password regularly and avoid using the same password for multiple accounts or devices.

Back up your data frequently.

Backing up your data is a good practice that can help you recover your data in case of malware infection, device damage, or loss. You can backup your data to a cloud service, such as Google Drive, Dropbox, or OneDrive, or to an external storage device, such as a USB flash drive, SD card, or hard drive. You should back up your data regularly and keep your backup files secure and updated. You can also use an app or service that can back up your data automatically and remotely.
