The keylogger will only get your password if you type it in. It won't know it immediately when infected. If you are using the passphrase to create a password, you would definitely need a random password that is seriously random. You can try to recite it to yourself three times per day or write it down on somewhere safe. If you are encrypting wallet keys, password will only protect you in the event of someone gaining control of your PC.
Can the keylogger get my password if I copy-and-paste it (no typing)?
yes, you need to use the keyboard of your pc(virtual keyboard) or typing it in a way to camouflage it(for example, your password is "my name is", instead you write my.name.is, then you delete those two dot, using the mouse)
use zemna antikeylogger free, it help a lot
You know there are mouse loggers, right?
yeah but it doesn't change that a logger memorize every characters you type, in sequence...., so their password in that case would be the first plus two "back space" and two underline of the mouse, resulting in 14 characters in total, versus the original 10
