|NewDotNet may be installed on your system with or without your knowledge.
The DLL component is a plugin to your Internet Explorer Browser. It needs when you use nonstandard Toplevel Domain names like .law, .club, .tech, .xxx and so on.
The catch is that nobody would see your domain unless they had the NewDotNet plugin installed on their computer.
Now that many new toplevel domain names have been approved by InterNIC, this new.net functionality is even less useful.
NewDotNet is good example of what's being referred to as Foistware.
NOTE: Foistware is software that adds hidden components to your computer. Usually it's done without your knowledge when you install some other program that would be useful to you.
This program is has been known to be installed along with KaZAa, Earthlink, @Home (ComCast), Juno, Webshots, NetZero, AudioGalaxy, Bearshare and a host of other programs.
It will also update itself without letting you know and it's unknown what new updated versions may do on your system.
It's recommended you use Add/Remove programs to remove the entire application.
(This DLL ties closely into the WinSock communication so if you just delete the DLL you'll screw up your system).
