Hi all! I have a pretty strange situation going on on my parents' computer.
My mom claims that she didn't install Sophos on her iMac, yet when she logged onto the computer today, a window saying "Threat detected by Sohpos Anti-Virus" popped up. I closed it, and it continued to pop up. I then deleted the Sophos app from Finder. I then tried to open Safari, and a window came up saying "You can't use this version of the application Safari with this version of Mac OS X. You have OS X 10.6. The application requires 10.6 or later," which made very little sense to me. I got the same notification for the Mail app, and various other applications. When I tried to open Disk Utility, I got the same error. I then restarted the computer in Internet Recovery Mode, and repaired the disk and its permissions. Still nothing. I then rebooted in Safe Boot, and I didn't get the Sophos popup, but the computer refused to connect to the Internet, claiming there was no airport card installed.
The virus detected by Sophos is "mal/nix-A," which when I looked up, apparently usually comes from a certain email. I looked through my mom's email on my computer, and couldn't find anything fishy. I'm very confused by what's going on, and my parents' computer is essentially useless as of now. Any help or guidance would be much appreciated. Thanks!
