I don't see any of the usual suspects but you do have some residual files left over from your Kaspersky Internet Security software.
You can remove them by downloading and running Find Any File to search for any files with the application's name and the developer's name in the file name. For Kaspersky software you'd do the following search(es):
1 - Name contains kaspersky
Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion.
FAF can search areas that Spotlight can't like invisible folders, system folders and packages.
Also you should uninstall Flash according to Adobe's instructions. It's end of life was on 12/31/2020 and all reputable websites no longer use it. Then now use HTML 5 which all modern bowsers use.
Go back into the Etrecheck report/App, go to the Clean Up section and remove the files listed there.
