Dear Christine, That same warning came up on another list I'm on -- please don't worry or blame yourself for anything. It's NOT a virus, it's just a silly hoax. So don't delete anything. If you already have, there are instructions somewhere (maybe somebody on the list has them) on how to restore that SULF file. It's a file that's there on everybody's computer to break up long URL's or something like that. And thanks again for all the information you have contributed to the group. Sincerely, Linda [email protected]
