Should you or should you not do the contest?

The contest for Hats, Part 3 has a link. Click it and it takes you to Stardoll.yahoo.net
Except...that isn't the real yahoo. The link can cause viruses.
When I clicked it I got really worried and asked all of OC, but I'm not so sure yet. So you can do the contest, but just don't click on the link.
It's basically asking you to make a hat through Stardesign Jewelry.
