One of them is the possibility of downloading an online APK virus that can infect your device and compromise your data and security.

What is an online APK virus?
Definition and examples of online APK viruses
An online APK virus is a type of malware that is disguised as a legitimate APK file that you can download from the internet. Malware is malicious software that can sneak onto your device and perform harmful actions, such as stealing your information, displaying unwanted ads, sending premium SMS messages, encrypting your files, or spying on your activities.
Some examples of online APK viruses are:
Fake Fortnite: This was a fake version of the popular game Fortnite that was distributed outside the Google Play Store. It contained spyware that could access the device's camera, microphone, contacts, messages, and location.
Joker: This was a malware that hid inside seemingly harmless apps, such as photo editors, wallpapers, or games. It could subscribe users to premium services without their consent or knowledge, resulting in high phone bills.
Cerberus: This was a banking trojan that could steal users' credentials, SMS messages, and contact lists. It could also bypass two-factor authentication and display fake login screens to trick users into entering their passwords.
How online APK viruses can harm your Android device and data
Online APK viruses can cause various types of damage to your Android device and data, such as:
Privacy breach: Online APK viruses can access your personal information, such as your name, email address, phone number, location, contacts, messages, photos, videos, browsing history, passwords, and more. They can then use this information for identity theft, fraud, blackmail, or other malicious purposes.
Performance issues: Online APK viruses can consume your device's resources, such as battery life, memory, CPU power, and network bandwidth. This can result in slow performance, overheating, crashes, freezes, or errors.
Data loss: Online APK viruses can delete or encrypt your files, such as documents, music, movies, or photos. They can also prevent you from accessing your device or apps by locking the screen or changing the settings.
Financial loss: Online APK viruses can make unauthorized purchases or transactions using your credit card or bank account. They can also subscribe you to premium services or send SMS messages to premium numbers that charge high fees.

Google Play Store: This is the official app store for Android devices, where you can find millions of apps that are reviewed and verified by Google. You can also enable the Play Protect feature, which scans your device for harmful apps and removes them automatically.
Official websites of app developers: If you want to download an app that is not available on the Google Play Store, you can visit the official website of the app developer and look for a download link. Make sure that the website is secure and authentic, and that the download link is not redirected to a third-party site.
Reputable third-party app stores: There are some third-party app stores that are reliable and safe, such as Amazon Appstore, F-Droid, or APKMirror. These app stores have their own quality standards and security measures, and they only host APK files that are original and unmodified.
Scan APK files for viruses before installing
Another way to avoid online APK viruses is to scan APK files for viruses before installing them on your device. You can use an online virus scanner or a desktop antivirus program to check if an APK file is infected or not. Here are some steps to follow:
Download the APK file to your computer: You can use your browser or a download manager to save the APK file to your computer. Make sure that the file name and size match the original source.
Upload the APK file to an online virus scanner: You can use a free online virus scanner, such as VirusTotal, MetaDefender, or Kaspersky VirusDesk, to upload the APK file and scan it for viruses. These scanners use multiple antivirus engines and databases to detect any malware or suspicious behavior in the file.
Check the scan results and report: After the scan is completed, you can check the scan results and report to see if the APK file is safe or not. If the file is detected as malicious by one or more antivirus engines, you should delete it immediately and avoid installing it on your device. If the file is clean, you can proceed with caution and install it on your device.
Use a reliable antivirus app for Android
A third way to avoid online APK viruses is to use a reliable antivirus app for Android. An antivirus app can protect your device from malware by scanning your apps, files, and downloads for viruses, blocking malicious websites and links, and alerting you of any suspicious activity or behavior. Some of the best antivirus apps for Android in 2023 are:
