Just take a look at the website address the link is trying to send you to. Expert-Exchange, MajorGeeks, TomsHardware, bleepingcomputer...for virus/trojan removal, those are the sites I trust (along with Symantec's site). But yeah, there are a lot of sites out there that promise to help you remove that one...if you'll purchase their software. Or download this free removal tool, which just gives you more infections. Or lists legitimate registry entries for you to Delete Now (!!!), only to find out you just royally screwed yourself. Stick with good sites, though, and you're cool.
Heck, I think it was bleepingcomputer that turned me on to Malwarebytes and ComboFix (another good removal tool I forgot to mention earlier...this one is actually designed to run when you're logged in to your computer in normal mode...its not afraid to attack the virus head-on! I picture Conan wading into battle when I light that puppy off! Oh, and the desktop icon very closely resembles the Thundercats emblem. Can't get much better than that!).
