Is there a virus that has target Sophos.
I use OS 10.9.3 and I have been using Sophos 9.x for quite sometime. Today my compter shut doewn and restarted a number of times. I nted in the report that Sophos was noted in a panic close (see below). Thge i get a notice out of nowhere (see below) as if from Apple, but not sure. I deleted Sophos frm the system and reinstalled it. Not only did the problem occur again, but my preferernces were affceted. Also, I notcie thatone of my two back up derives is ejected for no reason.
I ran Sophos at one point and not htreats wewre detetected, but it noted "issues detected" without explination.
What is going on?
