Avira Scout and Avira Software Updater

How can I remove from my laptop the following:

1/ Avira Scout

2/ Avira Software Updater

 

Avira Antivirus

Windows cannot send updates due to Avira Antivirus (not Aviva) - they suggest uninstalling Avira but it is not listed and I am not aware that I ever downloaded it. Presume its some sort of malware - any suggestions please if anyone has had the same problem
- thank you

AVIRA VIRUS SOFTWARE

Most antivirus programs require that you use a special utility to remove them. Avira seems to have changed its procedures from time to time, so I'm not sure which of the following would be best for you.

This is from a non-Avira site, so the usual caveat applies:
https://www.techsupportall.com/avira-uninstall-tool/

As the above site indicates, "Avira has stopped to provide its own removal tool to remove Avira antivirus. Now, they are just providing the usual instructions how to uninstall Avira antivirus through control panel." Avira does, however,
provide a "registry cleaning" tool along with the manual instructions:

Finally, as suggested by the first site, you can use (free) Revo Uninstaller. Revo is a trustworthy utility:
