I have uninstalled CCleaner, so I can't tell you now. This did happen on 2 computers in a small office of about 10 people. Both users are Standard, not Admin users. Updates would have been done either by running the install with Admin authority, or when logged into the Admin account.
If CCleaner Browser WAS installed, it was not intentional, and would have been done in the last update. The hyperlink problem just recently surfaced.
I might have missed the option to uncheck it. In the screen shot of the CCleaner installation (attached here), the Browser option is opt in (default) to install on the first screen. If one assumes that selecting the 'Customize' option would allow them to bypass additional software installs, the CCleaner Browser would still be installed.
I understand that providing a free version makes it necessary to bundle software to cover your costs, but doing it in an increasingly secretive and unexpected way to improve the number of unwanted installs, especially when it ends up causing multiple hours of debugging, is something I want to avoid. I will not be using CCleaner in the future.
