@leocg I set opera back to factory settings, it stopped thank you

Hello, I have this problem that every time i open opera GX a new tab opens in the background simultaneously, this exact website https://btc-alpha.com/en/trade/BTC_USDT?layout=basic&type=spot

I dont know what it is but it keeps getting on my nerves and im worried if it isnt some virus maybe? Please help me, thank you

PS: i already disabled all of the permissions of the website but i dont know how do I turn it off, before that it was showing some graphs of current crypto price etc...
