What do you need to know? RIGHT clicking on the Avira icon in the lower right corner of the system tray, then choose "Manage Antivirus" will bring up the basic Avira console. Once there, clicking on the "gear/settings icon" next to "Real Time Protection" will get you the basic scan settings for Real Time Protection. (You can also access this same screen by clicking on "Extras" in the upper left corner, choose "Configuration".) Here, I click on the + sign next to "Real Time Protection" on the left, where you can make your selections there,,,,, then the + sign next to "System Scanner" on the left and make sure both are set to "All Files". Most of the other scan settings I leave to default, although many also choose to "Scan Archives" in Real Time Protection, although that's up to you.
If you'd like to add or adjust the automatic scanning time, click on the "Scheduler" listing on the left side of the main screen. You can then adjust when the auto scans occur, or you can also add automatic updates or extra scan periods.
Hope this helps and if there's anything else you need, let us know.
