How to Remove a Trojan Virus From Your Computer Using Kaspersky Antivirus

If you are experiencing issues with a Trojan virus on your computer, despite having Kaspersky antivirus installed, you can follow a series of steps to help resolve the issue. This guide outlines a step-by-step approach to remove the trojan virus and protect your system from further threats.

Step 1: Update Kaspersky Antivirus

Ensure that your Kaspersky antivirus is up to date. Open the application and check for updates. Updating the antivirus ensures that it has the latest virus definitions to detect and remove any potential threats.

Step 2: Run a Full System Scan

Initiate a full system scan with Kaspersky. To do this, go to the scan or full system scan option within the application. This scan will help identify and potentially remove the trojan virus.

How to perform a full system scan:

Launch Kaspersky Antivirus on your computer. Click on the Scan option. Select Full System Scan. Follow the prompts to start the scan.

Step 3: Quarantine or Delete the Trojan

Once the scan is complete and the trojan virus is detected, proceed to quarantine or delete it. Quarantining isolates the file, preventing it from causing further harm to your system.

If you choose to delete the trojan, ensure you have backed up any important files before proceeding, as this action cannot be undone.

Step 4: Reboot in Safe Mode

To prevent the trojan virus from running during startup, reboot your computer in Safe Mode. Safe Mode prevents the trojan from loading, making it easier to remove the threat.

How to reboot in Safe Mode:

For Windows 10/11:

Restart your computer. Press Shift F8 to access the Advanced Boot Options menu. Select Startup Settings and then Restart. After the system restarts, select Safe Mode from the list of options.

Note: If you are using Windows 8 or earlier versions, you may need to access Safe Mode through the boot process or by modifying the boot configuration.

Step 5: Run Kaspersky Again in Safe Mode

After rebooting in Safe Mode, perform another full system scan with Kaspersky. This scan may help detect and remove the trojan virus that was previously undetected.

Step 6: Use Kaspersky Rescue Disk

If the trojan virus persists, consider using the Kaspersky Rescue Disk. This is a bootable disk that scans and cleans your system before the operating system loads.

How to use the Kaspersky Rescue Disk:

Download the Kaspersky Rescue Disk ISO file from the Kaspersky website. Create a bootable USB drive or burn the ISO to a CD/DVD. Reboot your computer and boot from the USB drive or CD/DVD. Follow the on-screen instructions to perform a system scan and clean.

Step 7: Check for Other Malware

Sometimes, trojans can be accompanied by other malware. Use additional malware removal tools such as Malwarebytes to perform another scan and detect any additional threats.

Step 8: Restore from Backup if Necessary

If you have a recent backup of your system from before the infection occurred, consider restoring from that backup. This can help you return to a previously safe and clean state.

Step 9: Reinstall Windows as a Last Resort

If the trojan virus cannot be removed and continues to cause issues, you may need to consider a complete reinstallation of Windows. Backup all your important files before proceeding to avoid data loss.

Step 10: Update Software and Systems

After successfully removing the trojan virus, ensure that your operating system and all software are up to date. This will help prevent future infections and keep your system secure.

Note: Regular updates and maintenance are crucial to maintaining the security of your system and preventing the installation of new threats.

Step 11: Practice Safe Browsing

To prevent future infections, take the following precautions:

Avoid downloading unverified software. Do not click on suspicious links. Keep your antivirus software active and up to date.

If the problem persists after following these steps, consider consulting a professional technician for further assistance.

By following these steps, you can significantly increase your chances of successfully removing a trojan virus from your computer. Regular maintenance and a proactive approach to security will help keep your system safe and secure.
