How can I find and clear belazyelephant virus from my website?

I want to publish some ads on Google but they say that I have got a virus on my website and the links are these: https://belazyelephant.com/?p=hezdsyjyhe5gi3bpgmztini&sub1=Dru&sub2=debt.v1, https://belazyelephant.com/?p=hezdsyjyhe5gi3bpgmztini&sub1=Frost&sub2=debt. https://belazyelephant.com/w_24.js I think they injected it over a plugin called Popup Builder because last year, my website got infected again because of this dumb plugin. How can I find and remove this virus? I searched the virus URL in my DB but I couldn’t find it, I also removed the plugin but no luck…
