The Windows autorun function for all connected drives like USB sticks, CD/ DVD drives and network drives bears a high security risk. This helpful function is used by malware and unwanted programs as a loop hole for hidden infections on the computer.
That's why, Avira Realtime Protection blocks the automatic run of storage drives by default, except CDs and DVDs. The following warning will appear:
If you like to deactivate this function, please open the Avira Connect, click on Avira Antivirus→ Extras → Configuration, then go to General → Security and uncheck the option Block autorun function.
Click Apply and OK to save the changes.
