First your hard drive is failing as it has already reallocated over 150 bad blocks. I recommend you replace it with an SSD as that will also give you a good performance boost. Since you have the 13" model you should also replace the hard drive SATA cable since that cable has an extremely high rate of failure on that model especially when using an SSD.
Second, you need to uninstall CleanMyMac and CCCleaner by following the developer's instructions or rather do not reinstall them on the replacement drive. Cleaning apps & anti-virus apps are not needed on a Mac and they usually cause more problems than they solve plus they impact system performance.
The EtreCheck report also shows you have multiple Flash plugins. Flash won't be supported for much longer (at end of the year?) so I suggest you avoid installing Flash on the replacement drive. I haven't had Flash installed on any system in over 6 years or more and I'm not missing anything.
I hope you have a good backup of your data already since it may be difficult trying to transfer data from your failing hard drive. If you do not have a backup, then I highly recommend you stop using this drive immediately since you will only make the failure worse. You may be able to transfer the data from the failing drive using standard tools/utilities while booted from another drive so it minimizes the wear on the bad drive (also turn off Spotlight so it doesn't try to index the bad drive). You may want to consider using Carbon Copy Cloner to transfer the data while booted from another drive as CCC can skip files that produce errors and CCC will log those failures so you know what was not transferred.
