This malware is called a paperclip exploit and can be very hard to notice once your are infected. It basicly changes your copy paste and can target specific types, like bitcoin addresses, wax accounts, exchange accounts or similar.
Best protection is to educate your self and set up ways for your self to help doing it properly. I.ex. using hardware wallet and a dedicated computer.
