dealing with w32/bagle

[Dan Hollis <goemon () anime net>]

I am curious how network operators are dealing with the latest w32/bagle 
variants which seem particularly evil.

Also, does anyone have tools for regexp and purging these mails from unix 
mailbox (not maildir) mailspool files? Eg purging these mails after the 
fact if they were delivered to user's mailboxes before your virus scanner 
got a database update.
