Possible Threat: Present pop up

Hello Adrian,

Sorry, this is not a threat, it is a legitimate campaign popup of AVG to purchase the AVG Ultimate Multidevice program with best offer price. You can open it inorder to know the offer price that is given to you.
If you aren't interested to know about the offer then please ignore this popup.
It is time limited and it will be stopped as soon as possible.

I've just noticed a pop up claiming to be a present from AVG.  Very suspicious I am thinking.  How do I remove this threat and protect myself in the future?
