How do I get ridd of this annonying program in Opera 27.0?
I'm not familiar with that one but my go-to programs are Malwarebytes, Spybot and AdwCleaner.
Get rid of it from your system. Make sure it didn't modify your startup shortcut (whatever shortcut you start Opera with). Then go to Settings and if you use "Open a specific page or set of pages" that their page wasn't added to the list, or added to the list of search engines. That's really it as far as Opera, unless you added an extension.
