Nope, you're screwed! ;)
The best thing to do is to make sure you don't have it. Do you have an Anti-Virus package, and is it up to date? Even though you may not have it there is a potential that thousands of machines connected to the internet do have it and may not be fixed in the near future. There will be a Distributed Denial Of Service attack against www.sco.com, but they know it is coming and they will be prepared to deal with it. The big question with this worm and any worm, virus or troajn, is whether the author(s) are going to take the opportunity to perform more dastardly deeds than they have in the past with these compromised machines that may end up being under their control.
