[Edit - first paragraph:] Not necessarily a solution, but I thought some of the old items went away by this method. However, I have three same-named fingerprints that do leave the Detected processes list by this method, but then when I delete the resulting exclusions, they appear again in the Detected processes list. So I still want a real method. We prefer to not edit the database directly.
In the SEPM 11, navigate to a CE policy > Centralized Exceptions page > Add > Windows Exceptions > TruScan PTP Exceptions > Detected Processes
Select the forced detection (fingerprint) to be deleted
Use the drop-down to change the action to Ignore
The item disappears
Return up a level to the exceptions list: CE policy > Centralized Exceptions page
Find the new centralized exception item (fingerpritn type) that you just created (probably at bottom)
Delete it. Repeat until problematic items are gone. Now you can repeat the forcing if you wish.
Thanks
