I see two issues: 1 - uninstall the Avast anti-virus software. It's totally not needed and will only compromise system and application performance; Do a search for the developer's instructions for uninstalling. When done rerun Etrecheck and verify that all of the Avast components are gone; 2 - Time Machine is not enabled. Do you have a current backup of your internal hard drive? If not that should be job 1. Operating without a backup is like driving without seat belts. You're fine until you need them.
And did you user this method to copy and past the report:
The report as posted has a lot of white space that shouldn't be there.
