[Dshield] Virus emails

Be careful firewalling by IP to stop these viruses. Since the virus 
emails to people in your Outlook address book, the computers that are 
sending these to you more than likely are from people you know (that is, 
people that have you in their address book). Which is one of the things 
that makes that nastly little attachment seem a little more harmless 
despite years of "don't open attachments on pain of surgical removal of 
clicking finger" warnings, because occasionally it looks like someone 
you know is sending you stuff.
	Anyway, I know most of the infected emails I was getting were from an 
off-site coworker who although happy that I helped her clean her 
computer up would have been particularly peeved if she couldn't send 
email to those of us in the office.
