Router accessible from the internet'

Purchased Avast Internet Security.

Done a scan of home network sucurity and get the message ‘router accessible from the internet’, then tells me to purhase what i have just purchased and used to get this far.

I thought when I purchased this item, it would sort things out, is this not the case.

If not I may as well go back to using the free software as I do not seem to be much better off!!

What OS/SP ?
What router (Make/model) ?
What exact version of avast ?

Please post a screenshot of the message.

Windows 10
Router: Technocolor/TG582n
Avast version: Product SKU: ISE-08-001-12-MR
Product Name: Avast Internet Security - 1 PC, 1 Year
