How to Remove Trojan Virus from Windows 11: A Step-by-Step Guide

When your computer starts acting up, running slow, or popping up strange messages, you might have a Trojan virus on your hands. Don’t worry, though. Removing a Trojan virus from Windows 11 is something you can do on your own. In just a few simple steps, your computer can be back to running smoothly.

Step by Step Tutorial: Removing Trojan Virus from Windows 11

Before jumping into the steps, it’s key to understand what we’re accomplishing here. Removing a Trojan virus is all about identifying and eliminating the malicious software that’s taken root in your system. Follow these steps carefully, and you’ll be on your way to a clean, secure computer.

Step 1: Enter Safe Mode

Boot your computer into Safe Mode to prevent the virus from causing more harm.

When you start your computer in Safe Mode, it only loads the essential programs. This makes it easier to remove the virus because it’s not actively working against you. To enter Safe Mode, restart your computer, and as it’s booting up, press the F8 key repeatedly until you see the Advanced Boot Options menu. Use the arrow keys to select Safe Mode with Networking and press Enter.

Step 2: Delete Temporary Files

Use the Disk Cleanup tool to remove temporary files.

Deleting temporary files might help speed up the virus scanning process, free up disk space, and even remove some malware. To access Disk Cleanup, type "Disk Cleanup" in the Windows search bar and select it from the results. Choose the drive you want to clean (usually C:), and check the boxes next to the types of files you want to delete.

Step 3: Run a Virus Scan

Use your antivirus software to run a full system scan.

If you don’t have antivirus software, now’s the time to get some. There are plenty of great free options out there. Once you’ve got it installed, update it to the latest virus definitions and run a full system scan. This might take a while, but it’s essential for finding and removing the Trojan virus.

Step 4: Remove the Virus

Follow your antivirus software’s instructions to remove any detected malware.

After the scan, if any malware is found, the software will typically guide you through the process of removing it. This might involve quarantining the virus, deleting it, or taking other recommended actions. Make sure to follow through with whatever steps your antivirus suggests.

Step 5: Update Your Software

Ensure your Windows and all software are up to date to prevent future infections.

Trojans often exploit vulnerabilities in outdated software to infect your system. To prevent this from happening again, make sure all your software, especially your operating system and antivirus, are up to date. You can check for Windows updates by going to Settings > Update & Security > Windows Update.

After completing these steps, your computer should be free of the Trojan virus. It’s essential to continue monitoring your system for any unusual activity and to make regular scans part of your routine.

Tips for Removing Trojan Virus from Windows 11

  • Keep your antivirus software updated. New viruses are created all the time, and updates help your software recognize the latest threats.
  • Don’t ignore software updates. Whether it’s your operating system or an app, updates often contain critical security patches.
  • Be cautious with email attachments and links. Even if it’s from someone you know, if it looks suspicious, it’s best not to open it.
  • Use strong passwords and change them regularly. This helps protect your accounts from being easily accessed.
  • Back up your data regularly. If you do get a virus that’s hard to remove, having a backup means you won’t lose everything.
