On windows 10:

1) Run settings. Search for "virus" and select "Virus & threat protection"
2) A new window "Windows Security" will open
3) Under "Virus & threat protection settings" click on "Manage settings"
4) Scroll down to "Exclusions" and click on "Add or remove exclusions"
5) Click on "Add an exclusion" and select "Process"
6) Enter the path to EDPro (usually "C:\Program Files\ExamDiff Pro\ExamDiff.exe")
7) Profit!

Presumably this applies to any anti-virus/malware application, if it scans every file that any other application opens to read.

Some av/am applications don't scan every such file on every occasion (unless you configure them to be paranoid).
