If so, it’s possible that your device has been infected with a virus. Don’t panic! In this article, we’ll guide you through the steps to diagnose and fix a virus on your Samsung Galaxy S7.
Identifying The Signs Of A Virus Infection
Before we dive into the solutions, let’s discuss the common signs of a virus infection on your Samsung Galaxy S7:
- Unusual Ads: You start seeing unwanted ads popping up on your screen, even when you’re not using any apps.
- Slow Performance: Your phone takes a long time to respond, apps crash frequently, or the device freezes randomly.

- Battery Drain: Your battery life is suddenly shorter than usual, and you can’t explain why.
- Data Loss: You notice that some of your files, contacts, or photos are missing or have been altered.
If you’ve experienced any of these symptoms, it’s essential to take action immediately to prevent further damage to your device and data.
Backup And Prepare Your Device
Before attempting to fix the virus, make sure to:
- Backup Your Data: Use Samsung’s built-in backup feature or a third-party app like Google Drive to back up your important files, contacts, and photos.
- Disable Accessibility Features: Go to Settings > Accessibility > Accessibility features and disable any features that you don’t use or recognize.
- Activate Safe Mode: Restart your phone and press the Volume down button until the Samsung logo appears. This will boot your device in safe mode, temporarily disabling all third-party apps.
Step 1: Identify And Uninstall Suspicious Apps
In many cases, a virus infection is caused by a malicious app that you’ve installed unintentionally. To identify and uninstall suspicious apps:
- Review Installed Apps: Go to Settings > Apps > Downloaded apps and review the list of installed apps.
- Look for Unfamiliar Apps: Check for apps that you don’t recognize or remember installing.
- Uninstall Suspicious Apps: Tap the app you want to uninstall, then tap “Uninstall” or “Remove” to delete it from your device.
Step 2: Update Your Operating System And Apps
Make sure your operating system and apps are up-to-date, as updates often include security patches that can help fix virus infections:
- Check for System Updates: Go to Settings > About device > System update and check for any available updates.
- Update Apps: Open the Google Play Store, tap the hamburger menu, and then tap “My apps & games.” Update all apps that have available updates.
Step 3: Run A Virus Scan
Use an anti-virus app to scan your device for malware:
- Install an Anti-Virus App: Download and install a reputable anti-virus app like Avast, Kaspersky, or Malwarebytes.
- Run a Full Scan: Launch the anti-virus app and run a full scan of your device.
Step 4: Perform A Factory Reset (Optional)
If the above steps don’t fix the issue, you may need to perform a factory reset to start with a clean slate:
- Backup Your Data (Again): Make sure to back up your data before performing a factory reset, as this will erase all data on your device.
- Perform a Factory Reset: Go to Settings > Backup & reset > Factory data reset and follow the prompts.
Additional Tips To Prevent Future Infections
To avoid getting infected with viruses in the future:
- Be Cautious When Downloading Apps: Only download apps from the Google Play Store or reputable sources, and read reviews and permissions carefully before installing.
- Avoid Suspicious Links and Emails: Don’t click on suspicious links or open attachments from unknown senders.
- Use Strong Passwords: Use strong, unique passwords for all accounts, and avoid using the same password across multiple sites.
- Keep Your Device and Apps Up-to-Date: Regularly update your operating system and apps to ensure you have the latest security patches.

What Are The Common Signs That My Samsung Galaxy S7 Has A Virus?
A virus on your Samsung Galaxy S7 can manifest in different ways. Some common signs include unusual behavior such as apps crashing or freezing, sudden increases in data usage, and unexpected pop-ups or ads. You may also notice that your battery is draining faster than usual, or that your phone is taking longer to charge.
If you’ve noticed any of these signs, it’s possible that your phone has been infected with a virus. However, it’s also possible that the issue is caused by a faulty app or a software glitch. To determine the cause, it’s essential to run a thorough virus scan and take steps to remove any malicious software.
How Do I Remove A Virus From My Samsung Galaxy S7?
To remove a virus from your Samsung Galaxy S7, start by restarting your phone in safe mode. This will prevent any third-party apps from running, which can help you identify if an app is causing the problem. Then, go to the Settings app and select “Apps” or “Application Manager.” Look for any suspicious or unfamiliar apps and uninstall them.
Next, download and install a reputable antivirus app, such as Avast or Kaspersky. Run a full scan of your phone to detect and remove any malware. If the virus is still present after running the scan, you may need to perform a factory reset. Be sure to back up your data before doing so, as this will erase all of your phone’s content.
Can I Remove A Virus From My Samsung Galaxy S7 Without Losing My Data?
In some cases, it may be possible to remove a virus from your Samsung Galaxy S7 without losing your data. If you’ve identified the virus as a malicious app, you may be able to simply uninstall the app and remove the virus. Additionally, some antivirus apps offer features that can help you remove malware without wiping your phone.
However, if the virus has infected your phone’s operating system, it may be necessary to perform a factory reset to completely remove it. This will erase all of your phone’s content, so be sure to back up your data before doing so. You can use Samsung’s built-in backup feature or a third-party app to save your contacts, photos, and other important data.

Additionally, keep your phone’s operating system and apps up to date, as these updates often include security patches that can help protect against malware. Consider installing an antivirus app that offers real-time protection, and run regular virus scans to detect and remove any malware.
Will A Factory Reset Completely Remove A Virus From My Samsung Galaxy S7?
A factory reset can be an effective way to remove a virus from your Samsung Galaxy S7, but it’s not a guarantee. If the virus has infected your phone’s operating system, a factory reset may remove it. However, if the virus has infected your phone’s firmware or bootloader, a factory reset may not be enough to completely remove it.
To ensure that your phone is completely virus-free, you may need to perform additional steps, such as flashing your phone’s firmware or performing a full wipe of your phone’s storage. It’s recommended to seek the help of a professional if you’re not comfortable performing these steps yourself.
How Do I Back Up My Data Before Performing A Factory Reset?
To back up your data before performing a factory reset, go to the Settings app and select “Backup & reset.” From there, select “Backup my data” and choose the types of data you want to back up, such as contacts, photos, and apps. You can also use Samsung’s Smart Switch app to back up your data to a computer or cloud storage service.
Additionally, you can use third-party apps such as Google Drive or Dropbox to back up your data. Be sure to back up your data regularly to ensure that you don’t lose any important information.
Will My Samsung Galaxy S7’s Warranty Be Voided If I Perform A Factory Reset?
Performing a factory reset on your Samsung Galaxy S7 should not void your warranty, as this is a standard troubleshooting step recommended by Samsung and other manufacturers. However, if you’ve rooted or modified your phone’s software in any way, this could potentially void your warranty.
It’s always a good idea to check with Samsung’s warranty terms and conditions to ensure that your phone is still under warranty and that you’re eligible for support. Additionally, if you’re unsure about performing a factory reset or other troubleshooting steps, it’s recommended to contact Samsung’s support team for guidance.
