Sophos keeps keeps shutting my (Snow Leopard) monitor down - but it doesn't lose power

I have a 3-year-old Intel Mac mini running OS X version 10.6.5. I have had 3 "anti-virus" programs running simultaneously on this computer:

•Sophos Anti-Virus for Mac

•MacScan

•AVG LinkScanner for Mac

When all three automatically start at boot-up, my monitor randomly goes dark - sometimes for 10 seconds, sometimes for up to 3 minutes.

Usually, to resolve the issue, I re-boot, only to have the issue recur.

I checked all connections and still have power coming to the monitor.

Turning off each of these three programs - one at a time - it turns out the culprit is Sophos Anti-Virus for Mac.

I was wondering if anyone could explain why. Is it that Sophos doesn't play well with MacScan and AVG LinkScanner? Is Sophos preferable to these other two? If I use Sophos alone, will it offer me more/better protection?

Thank you in advance for your knowledgeable response.

All the best, all the time,

  • I'll put them in here so that others can figure it out too :)

    1. press command-space
    2. type Console.app
    3. Console.app should be highlighted as the top hit
    4. press return
    5. a window opens with a bunch of text displayed and a listing of files down the left.

    Places to check:

    • DATABASE SEARCHES > Console Messages
    • FILES > system.log
    •             > ~/Library/Logs > CrashReporter >
    •             > Sophos Anti-Virus >
    •             > /Library/Logs > CrashReporter>
    •                                         > Sophos Anti-Virus.log
    •                                          > kernel.log
    •                                          > system.log
    •                                          > windowserver.log

    There's a lot of stuff to go through there, most of it fairly technical, some of it errors, some of it purely informative diagnostic information.  Searching for key words like "sophos" "intercheck" "video" "failure" and "error" using the search dialog might help you find what you're looking for.

    It's possible you won't find anything.  However, you might find that your computer's been trying to tell you something you need to fix in your system.log or in Console Messages that isn't even related to any of this software.  Always worth a quick check in these places if you're having problems.

    To more easily diagnose things, take a look at these logs, then restart with the software removed and look at them again -- check and see how the logs differ, and you've likely found the messages that have to do with your problem.
