Extra tab to AVG addon when launching Opera browser

I am running AVG Internet Security on Windows 10. Starting recently, every time I launch my Opera browser I get a second tab to the URL
AVG Online Security extension - Opera add-ons. How do I stop this?

Hi Aarthy,
The AVG extension was already disabled in AVG Internet Security settings, however I seem to have fixed the problem by following the steps given by John Pickering here:
