I disagree. If Listserv stuck to (or at least had the option to) distribute nonexecutable text-only messages virus contamination would not be a problem. As it is, Listserv distributes all files attached with the text message, virus and all. The newest viruses/worms do not even require that the file be opened in order to infect the recipient PC -- it only requires the right "host" be present, usually a Microsoft program like Outlook or Word. Listserv definitely needs the option to distribute text-only messages without any attached files. Apparently that used to be an option when you set a files=no option in the header. I use McAfee AntiVirus. A new virus database is available about every 10 days and maybe every month a new engine update is available. That engine update frequency alone tells you how fast viruses are evolving. I would expect frequent database updates, but frequent engine updates to detect the new viruses is alarming. This isn't your father's internet anymore, to borrow a phrase from Olds.
