and you will see it is a simple spam message. And no, it would be a good idea to not go to the site. I can't comment as to whether the site is likely to harbour malware, but there is probably a good chance it does.It would be a good idea to delete the message unopened.
As it stands you probably don't have a problem, just that your address has made it onto a spammers list somehow.
