First, you need to launch Windows Security to change some settings. Open the Start menu and enter Windows Security . Then select the Windows Security application .

Step 2:

In Windows Security , navigate to Virus & Threat Protection . Then click Manage Settings.

In Windows Security, navigate to Virus & Threat Protection

Step 3:

In Virus & Threat Protection Settings , scroll to the bottom of the page and click Add or Remove Exclusions .

What you choose depends on the type of exception you are trying to make. This is what each option will do.

• File: If you select this item, a box will appear allowing you to browse the computer to select a file to be excluded from future scans. Select the file you like, then click Open.
• Folder: Like the File option, this will allow the computer to search for a specific folder and exclude it from the scan. Content and subfolders in this directory will also be excluded.
• File type : A box will appear asking you to enter the file extension (e. g. . MID ) representing the file type that you can exclude. All files of that type will be excluded from future scans. This is very dangerous, because you can accidentally exclude a large group of potentially malicious files, such as PDFs or DOCs.
• Process : A window will appear asking you to enter the name of a process (a running program, such as explorer. exe ) to exclude from the scan. If a program you know is safe, but it will be flagged by Defender, you can enter it here.

Choose one of these options and make the necessary selections in the following pop-up dialog box. When you add an exception, it will display in a list on the Exclusions page .

When done, close Windows Security and your settings will be saved. The next time the system performs a Defender scan, the items you have added to the exclusion list will no longer cause trouble.
