Since installing Catalina on my iMac 27-inch, Late 2012 desktop computer, system performance has ground to a halt. Mozilla Firefox is unresponsive upon waking (works after restart). I uninstalled Webroot because a memo came out after I had already upgrading saying the virus software is incompatible. Help!

I would love to do that but part of my problem after the computer wakes up is that no links work. So I'll have to restart (which I have done 4 times in the last 2 days) and so far I've had to use Control+Command+Power becasue finder doesn't want to restart.
It's time to upgrade, guy.
8GB of 1600MHz DDR3? That's beyond slow (I know from experience)
Quad-Core 2.9GHz?
NVIDIA Graphics hasn't been supported in forever,
You've also got a HDD set to APFS instead of HFS (which slows things down even more)
It looks like you haven't cleaned your system in some time, too many applications, I see that you have 64 32-bit apps alone
You don't need a program like CleanMyMac, you need to go into your applications folder, delete stuff, go through your harddrive, remove things you don't need. If you're not going to upgrade, you need to optimize your setup. I'd suggest downgrading, try High Sierra. This was the last OS that properly supported your NVIDIA graphics.
But really, it's about that time to upgrade, man.
Yes, your mac a bit old, but I would not give up on it just yet.
You have a lot of old cruft installed. And you have two pieces of the worst software **** that are partially installed: cleanmymac and trusteer. Paraphrasing Oscar Wilde: to have one of them might be construed as a misfortune, to have two...
I would get an external SSD, do a clean install of Catalina and see how the Mac performs on that.
Please run Etrecheck and post its report here. Most likely there are other software conflicts and the report may help us figure out what.
How do I do this?
I found etrecheck and it is beach balling as it is trying to generate a report...
So I was thinking of getting a laptop to connect with the desktop since I find this easier to work on but could use better mobility. Would that be a reasonable move?
