AppleScript to disable on-access scanning

HI,

It was mentioned that Sophos on-access scanning can be controlled via AppleScript. Could you please provide an example AppleScript to disable and to re-enable Sophos for Mac on-access scanning?

I need to disable on-access scanning while a Mac OS X backup software ( SuperDuper ) runs because when Sophos detects a virus, it locks access to the file, the backup app retries, then aborts the whole backup. So the backups are not completing. It is more important to us to have a good backup, than to not backup infected files. We can run an AppleScript before & after the backup, so disabling on-access scanning seems like a good work around.

Thanks,

 Dave
