After signing up for CClean Pro and activating, I ran a number of programs:
Healthcheck, Performance Optimizer, Custom Clean, Driver Updater, and Registry.
I have been using the free CCleaner application for a number of years.
This time with CCleaner Pro, however, I seem to have damaged two of my four browsers:
Brave and Firefox. If I leave the browser temporarily to do another task, when I return,
the browser has become unresponsive. Sometimes the tabs that are already open will work,
sometimes not. New tabs typically do not work. Sometimes they'll say "Crash" if I hover
the cursor; mostly they refuse to accept a new URL by simply blanking it out. Do you
suppose Performance Optimization caused this by forcing a necessary background process
to sleep????? ... or what? I stopped all Brave processes, uninstalled it, and then
went looking for any leftover folders and files. I deleted them all until there was no
trace. Also ran the register cleanup. Then I reinstalled Brave. Same thing. Still
doesn't work. I have to kill it and restart all the tabs I was working on.
