I'm worried here-- Samsung tablet?

That my good friend is what we call a virus. I'd recommend going through your device and making sure there aren't any apps that you did not install. But the only way to be sure is a factory reset.

I received a galaxy tab 4 for christmas. I admit using the tablet I was looking at porn (this is the first time) on the internet. When I got off the internet app I had a messege in font of terms and conditions. Given the situation I tried reading some of it but ultimately didn't read it. I did read that the service runs on third party contributers and I hit a button saying I understood. Then a window opened telling me to speak into the mic whatever I wanted to say. I don't have terms and conditions to read what happened. My fear is what legal trouble am I looking at? And what's the charge? Please help.
