The indicator on the side of the CCleaner panel says 13 programs need updating. When I click on it only one shows up. I believe the updater is freezing because the pen device for that program is not currently plugged in. But, why does the side panel show 13 programs needing updates?
It is showing what it found at the previous check, if you do a new check the number in the side panel should change.
Note that you need to be online and to not have blocked CCleaner/Avast in your firewalls.
If you block CCleaner’s connections (and some do) then certain things like the updaters can’t work properly.
