How do I do this? Help please. Do I have to create that exclusion file?
Open Windows Defender Security Center.
Click Virus & threat protection.
Click the Virus & threat protection option.
Under "Exclusions," click the Add or remove exclusions option.
Click the Add an exclusion button.
Select the content you want to exclude from
Windows Defender Antivirus, such as:
File — Excludes only one file per exclusion.
Folder — Excludes a folder and its content, including sub-folders.
File type — Instead of excluding files and folder locations, you can configure the antivirus to ignore files with a specific extension no matter their location.
Process — Excludes background processes by name.
Continue with the on-screen directions to add the new exclusion depending on your selection. (For example, if you select File, you simply need to browse and select the file you want to exclude. Or if you select the File type option, you only need to enter the extension of the file format to skip during scans.)
Once you complete these steps, you may need to repeat the instructions to exclude other items you don't want the antivirus to scan to avoid false positives.
At any time, you can remove an exclusion using the same instructions, but on step No. 5, make sure to select the item and click the Remove button
