1. Go to Avira Promotion Page. Fill in salutation, your name, valid email, choose country and hit "Request license now".Reported that the license of APSS 9 can be use on Avira Antivir Premium 9, it's the same, not like the previous version which the license is separated and different between those two... you guys try it, maybe it's work.
2. An email will be send to you by Avira (almost immediate) with a valid 90 days HBEDV license key attached.
3. Download Avira Premium Security Suite if you not install it yet and key in the license given during installation to activate it or you could extend the current APSS on your computer if you're already had one installed.
