Any idea what might be causing this aler tot be generated?  I realize it's POP3
traffic (probably someone's internet mail acct.), but is there something new out
there generating these alerts?  I've actually got about 3600 of these alerts
which just started Saturday(8/18/01).  Need more info let me know.

Its detecting an email with an .scr attachment, which is a windows
screensaver extension.
Since you got 3,600 of these alerts, I'd be a bit concerned that one of
my users was infected.
I'd do a complete virus scan of all windows computers that you getting
these alerts from.
