Step 4.    On the following screen, there will be a tick in the "Participate in the avast! community" box by default.

Ensure you have saved anything you have been working on that has not yet been saved before clicking the Finish button as once you do, the computer will immediately begin shutting down and restarting..

 

That's it - you're done!  Once your computer boots up again, you should be running the latest version of Avast! Professional and can now enjoy the excellent new features and protection it provides. 

NB: You can now also DELETE the " setup_av_pro.exe " file you downloaded in Step 1.  If all went well, then it's served it's purpose and is no longer needed.
