How does the WIN8 system find and remove viruses? One quick way to check your computer for viruses is to use Windows Defender. This malware protection is provided with Windows to help identify and remove viruses, spyware, and other malicious software.

Note: If you are using Windows RT, Windows Defender is always enabled and cannot be closed.

If you are using Windows 8, you can run scanners or Anti-malware programs provided by other companies, depending on your preferences. To keep your computer running smoothly, you should install and run only one anti-malware application at the same time.

Use Windows Defender to scan your computer

Open Windows Defender in the following ways: Swipe from the right edge of the screen, click "Search" (if you use the mouse, point to the upper-right corner of the screen, then move the pointer down, click Search), enter Defender in the search box, and click or click "Apply "and" Windows Defender ".

Under Scan options, select the type of scan you want to run:

The quick scan checks only the areas of your computer that are most likely to infect malware, and any applications that are currently running.

The full scan checks all files on the hard drive. This scan may take one hours or more, depending on your computer.

The Custom scan checks only the selected files and locations.

Click or click "Scan Now".

To manually remove a virus

Sometimes a virus must be removed manually. This process is somewhat technical and can only be attempted if you are familiar with the Windows registry and know how to view and delete system files and program files in Windows.

First, run the Anti-malware application to identify the virus by name. If you have no anti-malware application, or if the Anti-malware application does not detect a virus, you can still determine whether it is a virus by finding clues about how it behaves.

Note the text in all messages displayed by the Anti-malware application, or if you received the virus by email, write down the subject line of the message or the name of the file attached to the message. Then search the antivirus provider's Web site for references to what you've written and try to find out the name of the virus and how it was deleted.

Recovery and Prevention

After removing the virus, you may need to reinstall some software or restore the missing information. Regular backups of files can help you avoid losing data when your computer is infected again. If you have not made a backup in the past, it is recommended that you do so from now on.
