Can either of you shed some light on the above message?  It contains
serious contradictions with both itself and the statements of Mr.
McAfee with whom it purports to agree.

The comments about DES and public key encryption contained in the
above message are extremely confused.  All indication is that the AIDS
trojan does simple substitutions on file names.  The above message
claims that the entire disk is encrypted with a public key encryption
scheme.

My conclusion is that this message was not posted in good faith.  The
last thing anyone needs is this kind of purposeful misinformation.
This conclusion is supported by the claim that the so-called SWE
company has moved and "returned" their sample disks to the owners.

By associating yourselves with this nonsense, you have seriously impaired
your reputations.

sincerely,
