It came to my attention a few days ago that unbeknownst to me, there appears to be a piece of software installed and registered on my system called n-Case. Now, n-Case is an ad delivery system which is responsible for many of the annoying popups that thanks to using Firebird as a browser, I don't have to see.

However, I don't like the fact that this software was installed without my consent, and when I try to uninstall it using the Control Panel, it says that I must connect to the n-Case server to uninstall this software. This is completely unacceptable that I should not be able to delete something off of MY computer at will, and without having to connect to the internet.

So, I ask you, in what ways can I delete this ad delivery system WITHOUT connecting to the internet, and how do I prevent future reoccurences of this type of thing?
