This post isn't going to interest many people (so I'll keep it short), but I'm considering it a "community service announcement".
Since I wrote my "Back to Identity" post, people have been landing here via search engines using variants of the phrase "how to remove Verdasys". I assume these are employees of organisations that have the Verdasys Digital Guardian (DG) agent installed on their machines and are trying to get around the system.
I have news for you. If DG is deployed within your environment the way it is in most organisations (with tamper-proof and invisible features turned on), you can't. That's not to say it absolutely cannot be removed. The system or security administrators (whoever is responsible for the DG environment) within your organisation will know how to because they have access to the administrative console and other related details (passwords and so on). Why don't you go ask them? :-)
