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

jerseyjoel

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 have had these programs running together without problems. It is of course not much help when people just say "it hasn't happened to me."

    I uninstalled avg linkscanner because in order to use it, I more or less had to shut down Little Snitch.  Somehow, in setting little snitch to allow  linkscanner do its thing, it also allowed applications ti  calling home, whether the applications were given permission to do so or not.   I even had iAntivirus installed and  running with together with Sophos with no crashes (though I uninstalled iAntivirus as I didn't know what would happen if the two programs ran into the same threat).

    I have used other antivirus products on the Mac, and I have had weird things happen (particularly with Virus Barrier).  So try uninstalling the Sophos and see if the bad behavior stops.  You can always reinstall. 

    Some time ago I tried to buy Sophos antivirus from the Beijing agent because it seemed to be the least intrusive of all the antivirus software I have tried for the Mac. I think I have tried them all!  I was told I couldn't buy it here, and I was reluctantly preparing to buy a a competing antivirus product when Sophos made the home addition available.  

    I have four Macs running in my home;  all of them are, and were,  similarly configured.
