[Ccleaner update installed on my PC without my consent.]

As already explained, there was absolutely no notification of this.

Automatically installing updates without prior notificaton and without consent and when installing updates it is clearly switched off in CCleaner is totally unacceptable.

And thanks, I already have removed the junk.

If you are afraid that your software could break systems, simply disable it. But do not play nanny games on your users.

There was no notification that an update would happen.

All automatic update settings in CCleaner were switched off - due to reasons.

Unacceptable. Uninstalled.

[Ccleaner update installed on my PC without my consent.]

Had installed old version 5.73 and every update setting switched off since long time.

Today somehow there was installed latest version 6.11 without any prompt / consent. After booting the pc, a full screen CCleaner notification about it appeared.

Why is that?
