Well this was just too weird and kinda creepy...

Really friggin' strange. My cousin sent me a cook book. So I was browsing for an ecard to send her. Then I decided to browse images of cartoon chefs and make her one. I was just randomly looking at images and this message pops up. I tried to shut it down. It wouldn't let me. Just told me 'Wrong'
Pay now because you got caught looking at porn. I had to shut my computer down to get out. It was like my browser was frozen. Weird. Never ran across that before??
Damn nation! They're coming to get me! They know where I live!

It's a scam. As you've probably guessed. Looks like most of them do---poor grammar being the tipoff. It wasn't written by a native English speaker.

I'd do a scan for malware and viruses and carry on.

Is it causing any problems or are you just making a comment?

Yes, I know it's a scam. Sorry... I'm just making a comment.
It was just weird how my browser locked up and I had to shut my PC down to escape.
I ran a scan already. Nothing was found.
Hark! There's a knock at the door...gotta go. Could be the Cops!
just kidding...

Well, I guess you are lucky that it didn't lock you out like most variants.

I think this is actually a scam of a scam, which is interesting, since it mimics the variant that does block you, but this you can simply just close it out or shutdown if needed and do a antivirus/antimalware scan just in case. I guess these days scammers scam other scammers too, LOL.
