A way to not get hacked?

No, topic assumes this is the keylogger's logfile, which contains your password, and was likely already sent to the hackers.
It's not the keylogger itself, which will just record your password again, or your new password if you change it. The original form of this method, that I saw on Nexon forums and I believe was also posted on Basil, spoke of changing your password using the Windows on-screen keyboard so as to never type it. Seems a bit extreme.

Copy/paste passwords then?
