Support for Opera browser and disabling for other browsers

I recently switched from Chrome to Opera and would like for Avast to check extensions on Opera. I would also like to disable requests for updates for browsers I don’t use (like IE). Is there any way to configure disabling updates/alerts on these other browsers and will avast be offering support for Opera any time soon?

Opera has to small a market share ( limited user base ) so that’s why it unsupported, concerning browsers! even if you don’t use IE it should still be kept up to date for security reasons “Windows Updates still require IE”.
