Clean "Opera" from obsessive porn adverts

If you suddenly caught an obtrusive porn banner in your browser, which says that you must send an SMS and you will be given a code that you enter into the banner, and it will supposedly disappear, or it will bore you for a month. All this is not good, because 550 rubles will be removed from you for SMS, and the intrusive banner will disappear. I suggest that you buy a program that instantly kills this banner for $ 5 (it works only on the Opera browser), so it's up to you !!!
