Norton Utilities 15.0--Privacy Health

I can use all of Norton Utilities 15.0 options except for when I am in Overall Health System under Privacy Health there is one

item, Bleach Free Space, that I cannot run.  I looked under Administer, went to Settings, clicked on Privacy in the list located

at lower left and found two unchecked items:  Glboally Clean Internet Explorer Tracks; and Hide Low Disk Space Warning.

 

I tried Norton Utilities 16.0 and I could bleach free space using it without any problem.  But I hated everything else about

the version and uninstalled it and re-installed Norton Utilities 15.0

 

If I choose to check Globally Clean Internet Explorer Tracks, will it do the same thing?  I certainly don't want it to erase anything

important.

 

As there is no real user guide, please let me know what to do.

 

Thank you.
