Slow down mac book pro

Question

hello
My mac book pro is running very slow
I have downloaded norton/symantec antivirus but it does not show any virus issue
I have performed a disk utility  repair but it did not point out anything
I have performed a disk utility permissions repair which showed a lot of things to be corrected but still no improvement
I have then downloaded Etrecheck and here is below its results, could you tell me what to do? (apart from  Time machine which I am upgrading right now)
Not sure why I have some many disks under Disk information too...
Thank you!

You need to get rid of Norton. It is notorious for causing problems on the Mac, and isn't much good at detecting Mac malware anyway. Uninstall it. To do that, you will need to run the installer again, which will offer to uninstall it since Norton is already installed. If you no longer have the installer, you will need to re-download it.
If you continue to have problems after removing Norton, see my Mac Performance Guide for further suggestions. Note that, aside from Norton, I see no other third-party software loading at startup that is likely to cause the problem.
