Malware, short for “malicious software”, refers to programs that are designed to damage or access your device without your consent. Android devices are especially vulnerable to malware due to their open-source nature and widespread use. However, there are steps you can take to dramatically reduce your risk of getting infected.

Use Trusted App Stores
The Google Play Store scans apps for malware before allowing them to be published. While not perfect, it does catch the majority of threats. You should avoid installing apps from third-party stores or websites whenever possible, as they do not have the same level of screening.
Some signs an app store may not be trustworthy:
- Requires you to enable app installs from “Unknown Sources”
- Apps are free when they are normally paid
- Contains pirated versions of apps
- Poor design and English translations
Stick to mainstream app stores like Google Play Store, Galaxy Store, Amazon Appstore, etc.
Keep Your Device Up-To-Date
Device manufacturers and Google regularly release security updates to patch vulnerabilities that could be exploited by malware. Keeping your device’s software up-to-date ensures you have the latest protections.
Enable automatic updates in your device settings to get updates as soon as they become available. Also make sure you are running the latest Android version your device supports.
Use Antivirus Software
Installing a trusted antivirus app like Bitdefender, Kaspersky, or Norton can catch malware that might slip past Google Play’s defenses. These apps scan newly installed apps, monitor device activity for suspicious behavior, and provide additional security features.
Many paid antivirus apps have free versions that offer essential protections. The small investment for the premium versions may be worth it for the extra features and enhanced malware detection rates.
Avoid Sideloading Apps
Sideloading refers to installing apps from outside of app stores, such as directly from a website or file. This bypasses the screening process from trusted app stores, exposing you to higher malware risk.
You should avoid sideloading apps unless absolutely necessary. If you need to install an app not available on Google Play or another trusted source, make sure it comes from a reputable and safe developer.
Be Wary of Unknown Links/Attachments
Like with computers, opening unknown links and attachments on your Android device can trigger malware downloads. Cybercriminals will try to trick you through phishing emails, text messages, messaging apps, etc.
If something seems suspicious, do not open it. Messages from unknown contacts or containing odd links/attachments are red flags. Verify safety with the source before engaging.
Use Secure Connections
Free public Wi-Fi networks can potentially allow cybercriminals to intercept your data. You should avoid accessing sensitive information or making purchases over unsecured connections.
For better protection, connect to private Wi-Fi or use a trusted VPN app to encrypt your traffic. This makes it much harder for hackers to spy on you.
Monitor App Permissions
Android apps request access to certain features and data to function properly. However, malware will often ask for unnecessary permissions in order to gather more of your personal information.
Pay close attention to permission requests when installing new apps. Only allow access to anything that seems relevant for that app’s intended purpose. You can adjust app permissions in your device settings as well.
Perform Regular Scans
It is good practice to periodically scan your device for malware or other vulnerabilities, even if you do not notice any obvious issues. Your antivirus app should have options for manual as well as scheduled scans.
Immediately uninstall anything flagged during scans to prevent further damage. You may also need to reset passwords, contact banks, etc. depending on the severity of the infection.
Back Up Your Data
While you hope to never need it, keeping reliable backups of your important data can save you from catastrophe if your device does get severely infected. Copy critical files to the cloud or external drives on a regular basis.
If factory reset ends up being your only recourse, backups ensure you do not lose your precious photos, documents, app data, etc. Make sure to scan the backups before restoring as well.
Avoid Jailbreaking/Rooting
Jailbreaking (iOS) and rooting (Android) refer to unlocking the operating system to allow more administrative control. However, this removes many default security measures and opens significant vulnerabilities.
You should avoid manipulating your device’s software unless you absolutely need advanced functionality. Even if you are careful, the elevated malware risk is rarely worth it for most users.
By following these best practices, you can keep your Android device malware-free and fully protect your personal information. Be vigilant with app installs, keep software updated, use antivirus apps, avoid suspicious links/attachments, stick to secure networks, monitor app permissions, back up your data, and never jailbreak or root your device unnecessarily. Paying attention to mobile security will let you fully harness the convenience of your Android without compromise.
