Yuou should Edit “My File groups” (click the group button on “my protected files”) and Create a group with all paths to “My document” (and desktop) folders of all users on you PC.
you need to append an * to those paths (eg C:\document and settings\username\my document* )
Then you should add that group to “My protected files”.
This way you’ll see D+ alerts when an app try to access these folder. Existing policies may not be affected.
I guess it would be better to use D+ in safe mode.
When you mark those alert to remember check th generated “protected file/foldes” allow/blocked lists.
You may wish to edith those paths to remove the * character or add it (IIRC CleanPC mode will use wildcarded entries while safe mode will add specific paths only)
