Windows 10 Upgrade & error message re AVG

Jane, Win 10 & AVG… For info have a look @ this article (http://avgclick.me/W10compatibility).

I recently upgraded to Windows 10 on my new Acer All in One PC.  I had AVG installed at the time and now each time I turn on the PC I keep getting the message:

AVG Internet Security
! Reinstallation required
Because you've upgreaded the operation system, AVG now needs reinstalling to function properly.  etc  

The problem is this seems to apply to a Windows 8 upgrade and the version of AVG I have is later and more up-to-date than the one this refers to.  How do I stop it popping up each I start the PC?  (Note I have the latest AVG installed 2015.0.6140)

Thanks
