@namer707 Halo
I don't know OPay.
With a google search I discover that OPay is a wallet based mobile app for sending money and paying bills in Nigeria and Kenya.
Kaspersky Internet Security with Safe Money is very good and trustworthy.
I've been using it for years and want to stick with it.

@leocg Kaspersky Support assigned me to the settings for secure payments, where you can select the browser from a list. Opera is not included.

Why can't Opera be a secure browser for payments?
Opera is my default browser, but it cannot be opened as a secure browser for Kaspersky payments.
I cannot add another browser manually. The security program only recognizes the other two browsers: Edge and Explorer.
