If Windows Defender detects a virus on your computer, the best thing to do is take the following steps to remove it and protect your system.
1) Stop using the device. Immediately turn off or disconnect the device from the Internet or other networks so that it cannot spread further and infect any other systems.
2) Scan your device with different anti-virus solutions. Try multiple anti-virus solutions in order to detect and remove the virus. It’s important that you run a scan with an up-to-date anti-virus solution, as viruses can mutate over time and be more difficult to detect.
3) Quarantine the virus. Take the infected file or files and place them into a quarantine folder. This will keep them from being able to spread further throughout your system.
4) Remove the virus. Use your anti-virus solutions to permanently remove the virus from your computer. Be sure to read the instructions carefully, as some viruses can be difficult to delete.
5) Update your system. Make sure that your operating system and all of your applications are updated with the latest security patches and fixes.
6) Perform a backup. It’s important to backup your essential data in case you need to restore your system.
7) Run a scan. Once you’ve removed the virus, run another scan to make sure that it has been successfully removed.
8) Monitor your system. Now that you’ve removed the virus, it’s important to stay vigilant and monitor your system for any suspicious activity.
9) Install a firewall. Install a reliable firewall to help protect your system from new threats.
10) Educate yourself. Finally, it’s important to educate yourself about how to protect yourself from malware in the future. Read up on antivirus software, update your system regularly, and be careful when visiting websites or downloading applications.
By following these steps, you’ll be taking precautions to keep your system safe from future viruses and attacks. As always, it’s important to be vigilant and monitor your system for suspicious activity, as new threats can emerge at any time.
