Working license files for Avast antivirus. Expiration date varies from 2016 to 2017.
The second license file worked for me on the first trial.
** Download Avast! free antivirus first**
** Then go to Registration (No need to go offline), click add license file**
** Go to your license file directory, Chose one of the license files**
** Try other license files if the first doesn’t work**
** Prompt for an update to Avast! internet security will appear, click yes and wait for the Update to finish**
YOU NOW HAVE AVAST! INTERNET SECURITY!!!
