Can Windows Defender detect and remove viruses?

Yes, Windows Defender is capable of both detecting and removing viruses. Windows Defender is a program included in Windows 10 and earlier versions that helps protect your computer from malicious software such as viruses, malware, and spyware.

Windows Defender uses a combination of real-time protection, automatic sample submission, and cloud-based protection to detect and remove viruses. Real-time protection scans all incoming files and programs and blocks them if they are malicious. The automatic sample submission feature allows Windows Defender to automatically share information with Microsoft when it detects an unusual file or potential threat. Finally, the cloud-based protection feature allows Windows Defender to checkVirustotal.com for information about the potential threat and take appropriate action if it is deemed malicious.

When Windows Defender identifies a virus, it can try to repair or quarantine the file, depending on its severity. Repairing involves attempting to clean or fix any damage caused by the virus, while quarantining isolates the infected file so that it can no longer cause damage. If repairing is unsuccessful, Windows Defender may delete the file. In addition, Windows Defender will also provide prompts and notifications to help you protect against and respond to new virus threats.

Windows Defender is fairly effective at detecting and removing viruses, but it may not be able to detect all types of threats due to the constantly changing nature of malicious software. Therefore, it’s important to supplement Windows Defender with other antivirus programs.

Overall, Windows Defender is a capable security solution that can detect and remove viruses. It should be used in combination with other antivirus programs to provide extra protection against threats.
