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?
There is a system in place to periodically update outdated/obsolete versions of CCleaner.
CCleaner versions 5.## have reached End-of-Life and so are currently being updated to the latest version, v6.11. https://support.piriform.com/hc/en-us/articles/13760826790669-End-of-Life-of-CCleaner-for-Windows-v5
In particular you should note that CCleaner versions below v5.92 no longer clear cookies effectively, because the major browsers have changed how they handle and store cookies.
