Smith,
No reason at all to be concerned. It seems you are using the McAfee Site Advisor, which is notorious for its "false positive" results. It blocks any link that it doesnt recognize or has not checked as well as what it knows to be bad - but doesnt differentiate between them
It probably has to do with the choice of an advert that google is serving up for you to see or possibly a member who is using an "unknown" or "unchecked" (by McAfee) link to an avatar, signature or countdown...
Either way, McAfee has blocked what it considers to be objectionable and the page displays without issue so the easiest thing to do would be to simply close the warning (x on the far right).
Here is a link to the detailed McAfee Site Advisor comments about Negril.com and we are given a green light (or checkmark):
