I got a webpage on my samsung sph-m840 Rain that says I tried to download an illegal video or malware and I have to get a green dot card for$300 and enter it's pin to regain use of my phone, all I can...

Pull the battery. If that doesn't work. Take it back to where you bought the phone. They should be able to get it up and running again. They will probably have to flash the phone. Probably going to cost something.
