There has been clipboard malware since long time ago. For example, if you want to send Bitcoin to someone, the Bitcoin address can be changed to a hacker's address immediately your paste in the address. That is why you need to check and recheck the address you are sending bitcoin to before pressing on the send button. The best in this regard is to uninstall you device OS and install back the OS to make it free of any kind of malware, some people will format the device like you did.
(virus is just one of the makeware, there are others like Trojan, Rootkit and Botnents. Some malware are combination of two or more malware to help achieve compromisimg the intended devices).
I am familiar with the clipboard malware. But like I said this is not the case. I am interested to see if anyone has any information on what kind of virus is this? This changes the deposit address and removes the QR code off the exchanges. It's like you login and you have already pre-set deposit address and QR code is nowhere near to be found in the exchange. And it's like this on any exchange.
Like I said I have already sorted the issue by formatting my PC but I am just asking if someone is familiar what this might be or explain a bit more?
