I use an old old old computer utilizing Windows 2000 professional, for work purposes. It does not ever go online. Through a flash drive, it has contracted the w32.sillydc worm. Are there any options for removing this? It doesn't seem to have affected anything, but every flash drive I attach gets infected and has to be scanned, which is getting to be annoying. (I have one flash that I can lock, so I can transfer files to without becoming infected, but that doesn't help when I need files transferred from.) Have used Norton on all my other computers for probably 20 years.
