I guess most people have heard about this on the radio or read it in the paper but in case you haven't -
There is real email virus going around called "Melissa-Macro-Virus" that hit last Friday, it already brought a bunch of email servers down.
I'm not 100% up to speed but apparently you get an email from someone you trust with a header saying something like "Important Message from USERNAME". The email then has a Word document attached, when you open the document it runs a macro which emails everyone on your email list with a copy of the virus. Apparently this document also has some porn web site URLs attached.
See the CERT web site URL below for all the facts.
Time to update your virus scanners! Norton already has an update, I guess all the others do also. I'd hate to see anyone here get hit by this...
