I just switched from free Avast to the Pro 4 version, downloaded it, installed it and re-started my PC. At no point in this process was I prompted for my license key, and that annoying red box telling me I've "expired" (which kinda cracked me up since I'm alive and well) keeps popping up. I just saw your suggestion about right-clicking on the desktop icon and providing the license key when prompted.
Will that get rid of the pop-up expiration box? And will I then be fully installed and protected?
Thanks!
