Well, this is an interesting plot twist: has your laptop an integrated key logger? How comes that?
Also: move your coins now. You are already late.
Just some kind of extension on Chrome, records every tap of the keyboard, nothing special. It just looks like Chrome has been left untouched. The whole HDD might be left untouched but it's definitely better to stand on the safe side.
Excuse me for being a bit paranoid, but are you sure the extension doesn't steal your personal data or everything you type on Chrome? At very least, check what kind of permission the extension ask.
