Hi,
You might try Authenticated Users or your User name...
You may need to do thid directly on the Security Software folder...
On rare occasions you may need to delete some of the other users, but be sure to keep anything involving the security program itself...
I don't have access to Win 10 at the moment, but have been seeing all kind of needless stuff in the permissions of some of my files...
Sometimes a half dozen users with just a number like S-**** **** **** **** ****...
Administrators, Authenticated Users, System, You, and possibly the actual program are all that you should need...
Be careful with this stuff... it can be a nightmare if it gets messed up too badly...
