Mac suddenly running very slow, need advice on EtreCheck results

Before you do ANYTHING backup the computer !!!!!!!!!!!!! Your HD is showing 69 errors, this means it is likely failing. Once you have backed up then restart in the Recovery Partition (Command + R on startup) and open Disk Utility and attempt to repair the HD. If after 3rd try you still get errors this means the HD is gone and needs to be replaced. Take the machine in immediately to an Apple Store or AASP in your area. You can locate an AASP by clicking

Macintosh HD (disk0s2) / : 899.32 GB (744.49 GB free) - 69 errors

Your hard drive may be failing. First and foremost make sure you have a current backup of the HD.

Boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and repair disk permissions and the disk. If the disk repair reports any errors and that they were fixed repeat until there are not errors found and fixed. Reboot normally and rerun Etrecheck to see what disk errors remain.

My backup is up to date, I ran a hardware check and found no issues, then ran the Disk Utility and it also said it found no issues but I hit repair anyways. After a restart I ran EtreCheck again and this is what came out. The computer is still horribly sluggish. Do I just keep repeating the Disk Utility check and repair step???
