Hacker with bank card number?

I submitted my credit card number to Netflix for recovery today. (Number only)

I noticed that I have a virus on my PC that is saving my keys (keylogger)

Now the question would be whether the hacker can do anything with my credit card number?

Hm. So if you yourself already say you have a virus on it that controls what you enter… (I don't know anything about that, but with credit cards) I would block it. Then you will receive a new one from your bank. So should get a new one. If you don't call your bank, say you had to block it because of suspected abuse and then you will get a new one.

Safety first!
