How to uninstall ClamAV?


I made the terrible mistake of installing ClamAV on my Mac a few weeks ago and whenever it runs it literally kills my machine (even 5 hours after I scheduled it to run cause it's still running). I tried uninstalling and just dragged the app's icon to the trash but the process 'clamscan' still runs.

Can someone tell me how to get rid of this thing once and for all? It's driving me NUTS!
