FRIENDFNDWC is Adult Friend Finder (
www.adultfriendfinder.com). If you didn't sign up for an account there, then somebody else did with your credit card. Could very well be that somebody stole your credit card number either through phishing or because your computer is not secure and you were hacked. If you have ever signed up for AFF (or any of their other dozens of dating related sites), then they do have a nasty habit of changing your billing preferences to Auto Renew without your knowledge and being automatically billing you for the period of time that you chose to renew the first time for.
