Two Thoughts:

• Misacting Keyboard:

Reset the SMC and your NVRAM:

Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Keyboard) become manipulated, technically. So, reset the SMC and NVRAM. Your hard drive may not be being read promptly, so resetting these, all of the ports would be configured to how they should be.

• As for Malware:

Malwarebytes for Mac:

Malwarebytes searches for malware (short for (malicious software) and spyware. It is created by longtime users of these forums making it the only reliable Security Software for a Mac. So, scan with it and remove what is found, from the quarantine.

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes Uninstaller

It may be best to reset your Mac to factory settings and to create a backup of the data you currently have on it. Although the chances of getting malware on your Mac are lower than to other pc's there are still chances that your Mac could have it. So when you reset your Mac to factory settings it will remove everything that is on the Mac including malware and the only thing that will be left is the software (Mac OS Catalina) that is directly form apple which will already be on your Mac, and you should be good to go. Also make sure to update your Mac too.

"typing problems and maybe a malware on my iMac: I want to say that malwarebytes accomplished to find a malware... incredible!!! I’m now wondering why malwarebytes is better than all the other virusscanners on the Mac... The malware calls PUP.Shared.IOBit... Do you know that type of malware?”

An AppleScript Created-Program:

Searching for it, I find nothing of it on a search engine.

Google Search Queue: “PUP.Shared.IOBit”

It is an unwanted program that is just going to get in the way and is useless.

Perhaps one that you or someone created using AppleScript. A typical Security Software program wouldn’t look for an AppleScript app.

So, be sure you remove it from the quarantine too.

"typing problems and maybe a malware on my iMac: What’s wrong with Avast?"

-------

Security Software Gets in the Way on a Mac:

You will notice Avast getting in the way when accessing certain sites on the apple.com domain. Also, Firewall settings sometimes don't allow certain sites to go through. So, uninstall it, as it just gets in the way. User Preferences in it may have its own settings for keyboard shortcuts. And Privacy Settings may not allow video to play, nor email to go through. You won't find viruses on a Mac.

Plenty. See this discussion and follow John Galt's advice.

"I immediately put a virusscanner (Avast) on my iMac"

That was a bad move. You should get rid of Avast. Use the developer's instructions.

Emblem on Taskbar:

Hovering your cursor over the emblem to the far-left, what pops up (no no need to click on it, I think). As for the space - there’s probably room for two more emblems, yet to-be-used.
