I just updated to OS X 10.11.4 today and was running the old version of Sophos for Mac. It told me that it couldn't start the On Demand Scanner. I then found that there is a new Sophos Home and installed that.
I'm still having the same issue. It tells me that "Automatic Virus Protection is Off" even though the dashboard shows it as on.
I'm guessing this might be an issue with the latest El Capitan... Anyone from Sophos wanna make a comment?
