imac running slow and giving spinning ball of death. Please help, EtreCheck report enclosed.

Problem description:

Slow computer, frequent spinning ball of death. Especially when browsing using any browser (safari, firefox, chrome). I've tried rebooting, clearing caches and disabling/removing extensions. Sometimes I get a temporary improvement but nothing seems to have worked to resolve the problem sustainably.
