True only if he uses Microsoft Outlook or Outlook Express.  Other mail
 programs use other ways of indicating the presence of file attachments.

Possibly, although most recent anti-virus programs scan incoming e-mail by
 default.  In order for that not to happen, you'd have to intentionally
 turn e-mail scanning off. More likely is that they have failed to keep
 their anti-virus software up to date.  That's the most common
 virus-related problem I have with my customers (I'm an ISP in real life).
 
 When you buy anti-virus software it includes a "virus description
 database" that includes all viruses known at the time the master copy of
 the installation CD was produced.  Any new viruses that appear after that
 are not known to the anti-virus program, so will not be detected.  You
 *must* use your anti-virus software's "update" feature on a regular basis
 to download and install the latest version of the virus description
 database.  If you don't, your anti-virus software is virtually useless
 because it can't detect new viruses.  The Klez.H worm that is currently
 causing so much trouble is very new (first detected only a couple of days
 ago), so chances are the anti-virus software on most MG-TABC members' PCs
 wasn't up to date enough to catch it.
 
 If I used a PC, because of the rapid-fire release of new viruses I'd run
 my anti-virus software's database at least once a week.  On a Mac it isn't
 as critical because new Mac viruses appear very infrequently.

The virus name is always Klez.H or some variation on that.  What changes
 is the "Subject:" line of the message, the text (if any) of the message,
 and the name of the file attachment.  Klez.H takes each of these from a
 built-in list which is so long as to make the Subject, text, and
 attachment name seem random.
