Licensing and Upgrade
In order to be able to use your Avira product, you require a license. You thereby accept the license terms.
The license is issued via a digital license code in the form of a .KEY file. This digital license code is the key to your personal license. It contains exact details of which programs are licensed to you and for what period of time. A digital license code can therefore also contain the license for more than one product.
If you purchased your Avira product on the Internet, or via a program CD/DVD, the digital license code is sent to you by email.
