Hi @MeganCCleaner,
Thanks for the additional info!
When I use try to use CCleaner to uninstall I get similar behavior as other methods. The mouse spins for less than a second and then stops.
I tried CMD as an admin, ran the command and get:
C:\WINDOWS\system32>C:\Program Files (x86)\CCleaner Browser\CCleanerBrowserUninstall.exe" /run_source=cp
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
