Seems like its working better now.
Select
Home. Now, for the license, double click the orange ball. Then click
Maintenance > Registration. From the right side, click
Insert avast! PRO antivirus / Internet Security License File. Locate and select the license file then click
Open. You'll receive a confirmation message if it works.
Also my action center is saying my avast is out of date its 5.0.462
Don't worry avast will update itself.
