avast icon

I have used avast for some time and have always had the blue ball spinning. It told me that I was about to expire and so I downloaded the new one but it didnt give mne a key as it has in the past and all the icons are orange. it looks really different. Have I done something wrong.

Nope. Your copy of avast was upgraded from version 4 (blue icon) to version 5 (orange icon).

curiouser, go to Settings > Maintenance and register your new avast version (if necessary).
