PUA explained as I was unable to fix broken link in my reply:

Thanks for the above links, as well as your other response regarding Adobe ARM. I'll give them a read.
I'm certainly no tech wiz, but I would like to be at least "half-way aware" of what should not be disabled on my operating system.
I'm usually very careful when installing programs, and updates. I scan each window carefully to avoid installing unwanted
bundled "stuff"; e.g., Chrome. I become worried only if there is bundled stuff that the install windows don't provide a check box to opt out of.
As I mentioned above, I uninstalled the regular free CCleaner, and installed the slim version. Everything seems to work peachy.
Today, I followed your links to the discussions at MG and Piriform, and it appears that nothing is secretly bundled with the regular free version after all, yet I could still be wrong.
