I can’t found Browser cleanup menu on latest version of client.
How can I use a browser cleanup?
As far as I know, it is part of the smartscan unless you have the standalone version of the BCU installed.
Confirmed.
Thank you for answer. 
What is the BCU?
I found afb_endpoint_premium. PDF file.
This file contains the browser clean-up function.
BROWSER CLEAN-UP (PC ONLY)
Deletes annoying and unwanted toolbars or plug-ins that slow
down or hijack browsers.
Previous client versions had a browser cleanup, but the program GUI changed and disappeared.
