Since downloading Monterey my 2017 iMac has slowed to a snails pace. How can I uninstall it and return to Big Sur?
iMac 21.5″, macOS 11.6
I don't see any of the usual suspects in your report. However, you did or do have VirusBarrier Scanner installed. You should uninstall it according to the developer's instructions. You do not need any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac, ever!
Also you haven't booted for 7 days. You should reboot more frequently, like every other day. That will clean out temporary system and applications cache and swap files and help keep the system and applications more efficiently. I shut down at night and boot up in the morning. The time it takes is not an inconvenience.
You have quite a few apps in your System/Users & Groups/Login Items preference pane and running in the background. Remove all of them from the preference pane and open them only when needed and close when done. They can be added to the Dock for easy access.
You have a Fusion drive. Boot into the Recovery volume (boot with the Command + R keys held down), launch Disk Utility and run First aid on all volumes. If you get any errors reported make a note them and rerun First Aid till there are no errors reported.

Thank you Joekenya for your advice. I don't want to go back to Big Sur but get Monterey working on my iMac. I hope you can advise me on how to get this sorted out. I did the Etrecheck and put it in the additional text.
It would be best to figure out what is causing the slowdown.
Download and run Etrecheck. Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.
IMPORTANT:
Before running Etrecheck assign Full Disk Access to Etrecheck in the Etrecheck's Privacy preference pane so that it can get additional information from the Console and log files for the report:
Also click and read the About info to further permit full disk access.
Copy the report
and use the Additional Text button to include the report in your reply.
Thanks for your advice Old Toad. Downloaded Etrecheck, review report and discovered multiple issue. All is well now, good advice.
Thank you Old Toad, very helpful. I will do as you suggested and see if it works :-)
