Laptop keyboard: letter w not working anymore

Every w shown here is copy-pasted. For some reason, I can’t type that letter anymore. I’ve googled it but that gives me something on databases in sweden >_>
McAffee virusscan shows nothing wrong…
Ideas?
EDIT: CTRL+w is working just fine. This being the shortcut to close a tab.
Answer #1
Hmmm that shows the key is working as such…
Is it a laptop or a normal keyboard?
A temporary solution is keyboard re-mapping, I spilled water on a keyboard once and 2 keys didnt work, so I re-mapped them to keys that I never used. Not perfect but may get you out of trouble for a while
(Can be found simply with a Google search BTW)
