I have to disagree. While you're right in saying that a keylogger records key strokes, a keylogger AND screengrabber (used to record your screen on a click, or other triggers) can just as easily infect a computer and, if you've got a really good model, you might not even notice a dip in performance. The undisputed best thing to ever do if you feel your computer might be compromised is: stop what you're doing, disconnect from the internet, and do a full scan on your computer with a virus scanner/Malwarebytes with up-to-date definitions. Your accounts, your personal information, all of these things are far too precious to risk because you might feel like you can 'outsmart' the bit of malware when you're not even sure of what you're dealing with... oh didnt realize my bad
