If you want to have MDaemon automatically update your SecurityPlus (or MDAV) virus definitions automatically when MDaemon starts up, it’s actually very simple to do.
Open notepad, edit the C:\MDaemon\App\startup.bat file. If it doesn’t exist, create it.
Add the line “echo. > C:\MDaemon\app\updateav.sem” to the file (I’d suggest adding it to the very top or very bottom)
That’s it! From now on, MDaemon will perform an antivirus update shortly after restarting. You can’t get much easier then that.
