Slow running Mac

Yesterday my iMac OSx 10.10.5 Yosemite started running really slow. beachballing for several minutes regardless of what I tried to open. Also noticed that the jpg files I had on my desktop weren't fully loading. I've scanned with Avast and found nothing malicious. I have tried several save reboots also and nothing happens. I tried to open the app store so that I could upgrade to El Capitan and it crashed every single time I tried it. I downloaded EtreCheck and this is the report I got.
