Swen virus activity, and how Greyware Automation Products dealt with an attack.

Very interesting, and I agree that a "quiet" virus may be spreading as we speak. Since the MS patch didn't work, and users are slow in applying the patches that do work - there is plenty of opportunity for someone to write a virus that doesn't attack or do anything exciting except to self-install when the opportunity is presented (during a download for example) to do so and then lay idle...doing a date check on boot waiting for the date to activate. I guess like Herpes or HIV?
