And, yes I actually DID say that I was backing up to an external cloud based drive. I even asked for advice for a newer one to use. I even went back to read my answer to make sure it hadn't been deleted. It hadn't. So I truly appreciate your advice, I'm frustrated that it feels like some of you are not reading what I've written.
OK, the record needs to be made straight regarding this.
Here is what you said above:
"I've been using Backup my PC (I will need to change to another backup since it doesn't support 64 bit encryption I just read.) I just upgraded to High Sierra last week but not being able to switch back to Google search engine issue predates that upgrade and continues after.
What would you recommend as back-up when I change? (Would Apple do? Most of my work is being saved to the cloud by default now). Also what would you do for a manual cleanup and what software is best. Cleanup my pc seems to have been inadvertently downloaded in the last few months. I thought I had tossed it but like a bad penny... I read on this forum that it causes more problems than it solves but that may be one participant's opinion (though I seem to recall he had a level of expertise)."
First, UNLESS you are using an "emulation" program/method on your Mac, Backup my PC will not work on a Mac. Maybe you need to explain that better.
Secondly, when you say "Most of my work is being saved to the cloud by default now)", I have never used "the cloud" (don't trust it, especially with any private information I have). Maybe there is a way to do that within the Mac OS. So you need to explain that.
Here is a link that discusses SOME ways of backing up a Mac:
https://support.apple.com/mac-backup
Most folks who visit this site use Time Machine for backups, and it is OK. But I (and some others) use SuperDuper!, which creates a
bootable backup/clone of your internal drive. That's right, I said
bootable (Carbon Copy Cloner is s similar, stellar product). It definitely makes recovery much easier, and also is the way to go when one wants to do a clean, fresh installation of a newer Mac OS. Here is a link for it:

As for cleaning up/maintaining/repairing (from a software perspective) tasks, first you can do quite a lot of clean up on your own. Also, there are some excellent products available (both free and commercial) that can help you with those tasks.
Two other questions:
1. What Mac OS were you using prior to High Sierra?
2. How did you "upgrade" to High Sierra? Did you just do it "in place", ie, basically let High Sierra over write what was on your system already?
It would be best to first get rid of this "Bing-related" virus, and I already provided the steps in a post above to do that. Then, choose which Mac software you want to use for backups, preferably to an external device. Then we can discuss/recommend software for disk cleanup/maintenance/repairs.
