Thank you for the links.

I can find no information that says that a user account would be created automatically with the name "varnish", and without the administrator's (my) knowledege.  In addition, Bitnami and Wordpress state that varnish is disabled by default, and I didn't enable it.
I did install Wordpress as well.

Sorry to ask the question again in a different manner:

Does varnish create a new user account in os x 10.6.8 (when enabled) which one sees when logging into the computer?

If not,  I can only think that I'm dealing with another source of this mysterious user account (hacker or other software).

Thank you so much for your time,

Sincerely,

Eric
