Hello hazzo31, and welcome to avast!. Posted logs shows no active malware on your system. The logs shows no presence of any PUP software or remains too. It look like Malwarebytes and previus used AdwCleaner got them all.
So, you may manualy remove the C:\AdwCleaner folder as you didn’t press Uninstall button in tool’s gui.
You may also take a peek into this folder. If it is empty you may delete it if you want. Or you may leave it, it is your will.
C:\Program Files (x86)\Brother
