Answer 1

It is necessary to exclude from check from all PC using that program by the following procedure.

Add an exclusion to Windows Security

1. Go to Start > Settings > Update & Security > Windows Security > Virus & threat protection.
2. Under Virus & threat protection settings, select Manage settings, and then under Exclusions, select Add or remove exclusions.
3. Select Add an exclusion, and then select from files, folders, file types, or process. The exclusion will apply to subfolders within a folder as well.
