Prohibited software is not blocked

Prohibited software is not blocked

Hi,

for testing purposes I installed CCleaner on a client. After inventory was done CCleaner ist listed in DesktopCentral. I then added it to the list of prohibited software, but still the app is running on that client. When checking the tray icon  I get this:






Afterwards I added  CCleaner64.exe and CCleaner.exe to the category blocked software, but this has still no effect.







In idea why software is not blocked?
