Streaming subscription popup malware on YouTube

I got infected by malware in the strangest way possible. I was watching YouTube and in one moment, I got a message that my streaming subscription is over, so I clicked on that popup, and from then on my pc started behaving in a strange way, and it’s becoming much slower. Is there a way to clean this malware?

Hello @Porter

If this is the malware problem then you can use Malwarebytes
