My AVG Internet Security Has Died

I opened AVG to run my regular scan today and got a red flag message saying I must restart my PC, which I did. 
I opened AVG after my PC restarted and AVG seems to have died.
The usual screen is blank with a message saying "Your're protected". There is also a long url across the top of the AVG screen which looks extremely dodgy.
Help please.

Hi,

Let's work together to fix this issue. You do have an active AVG Internet Security Unlimited valid until 3/14/2019. Please repair AVG Internet security http://support.avg.com/SupportArticleView?urlname=How-to-repair-AVG from the control panel and restart the device to check the status.

If the issue persists, share the screenshot [http://support.avg.com/SupportArticleView?urlname=How-to-create-a-screenshot

] of AVG Interface to proceed further.

Thanks.
