First you have two anti-virus apps installed. You should never have more than one anti-virus app installed at a time since they will step on each others toes.
However, you do not need any anti-virus software, cleaning apps, or third party security software on a Mac. The built-in security features of macOS combined with due diligence on your part by practicing safe computing habits is more than adequate to keep your Mac (or any computer) safe and operating properly. See this excellent article which is full of extremely useful information writen by a well respected community member:

You should uninstall both Avira and CleanMyMac by following the developers' instructions. These types of apps usually cause more problems than they solve as they interfere with the normal operation of macOS and usually cause performance issues as well. If you are still having problems after completely uninstalling both of these apps, then run EtreCheck again (with "Full Disk Access") and post the new report here so we can review it again with the updated information.
