McAfee now detects the password protected zip files.  (There are other
things you can look for besides trying to decrypt the contents of the
zip filel  Also, zip passwords are weak and easily broken anyway.)

BTW, there is a war going on right now between three virus groups, so
you will continue to see new variants of Bagle, Netsky and Mydoom for
the foreseeable future.  Should be a very interesting month.
