Hello guys! I've came to help you and everyone who will searching for it.
So, I've been trying to drop this piece of s**t for all day. Nice application, hackers, no way to remove it, if you are simple Mac user.
So, for remove this s**t open terminal in Mac and execute:
sudo rm -rf /applications/CCleaner.app
If you changed directory, where this s**t was installed, you should firstly locate it.
Use in your terminal:
ps -ef | grep .app
and find CCleaner.app
Good Luck guys!
