I've spilled water on my laptops keyboard

Last night I accidentally spilt water on my Windows 7 laptop. Almost all of the water went on my laptops keyboard and now when I press certain numbers or letters, two characters will appear. For example when I press "6", "6f" will appear or when I press "8", "8n" will appear. I've looked up loads of sites and tried every suggested solution but none have worked. Also when I press "a", instead of actually typing the letter, "Help for Internet Explorer" will pop up on my screen. I'm really confused and frustrated so it would be great if someone could finally help me fix this.
