Yes, there are quite a few.
I personaly use
Dr.Web's LinkChecker. It's really easy to install since it's a plug-in for your Web browser. It'll add an option when right-clicking a link on the Web to scan it before opening it.
You can also paste the link's URL in
Norton Safe Web.
And, of course, there's
WOT. It's especially useful when clicking on links in a Google search.
