All good AV programmes now detect Lipreffs.Worm and Rol.vbs and they also detect others as they become known to the AV companies. I use Inoculate IT which I think is better than Nortons, though Nortons have an excellent awareness/security related website. You can never have too much information I reckon.
The sad reality of this whole situation is that if people obeyed advice not to visit websites that are mass-advertised (most often via /msg or /notice) then it would be unlikely that any network would get attacked. I will soon be updating my own website with a swathe of new info about how to prevent being infected but the old addage holds true...
You can lead the horse to the water but you can't make it drink.
