None the less that simply means they did not damage Mac OS until now!!!! They only need to be installed (not necessarily running) to cause havoc.
I see some issues in your report. First is you have Avira & NordVPN installed which are both considered malware by most experienced users on these forums. Mac OS is catlike in that it cleans itself, Mac OS does not benefit from nor does it require any of the following types of third party apps:
· Antivirus Apps
· Cleaning Apps
· Security Apps
· VPN Apps
· Maintenance Apps
What these types of apps do is the exact opposite of what users want. They make Mac OS slow, appear buggy, can damage Mac OS and sometimes create unwanted behaviors. In short, they are really bad news!
So the first order of business for your computer is that you need to locate the developers. uninstall instructions for both of those apps and please uninstall. Because they are pretty nasty they tend to leave parts behind after being uninstalled, a testimony to how poorly written they are! To fully ensure you have uninstalled please download the free version of FindAnyFile directly from the developer. Then have it search your system for the following:
Have it Trash any files with those names in them and then ensure the Trash is empty. Finally restart in Safe Mode and then restart normally. If the problem persists then please provide an EtreCheck report of your computer so we can check to see if there are any other major issues.
If they have damaged Mac OS as I suspect then you will need to re-install Mac OS to fill in any missing or damaged pieces caused by NordVPN and/or Avira AV.
Moving forward NEVER EVER install the types of third parts apps noted above unless you don't mind a slow, buggy and poor performing Mac.
