NewDotNet is an Internet Explorer spyware/hijacker plug-in. It is not something you want to have on your computer. NewDotNet can change browser settings, can display commercial advertisements, can connect itself to the Internet, can hide itself from the user and stays resident in the background.
NewDotNet also tracks the user’s browsing history and will display unwanted commercial advertisements. And, NewDotNet can install itself as an LSP (Layered Service Provider) amidst your Windows Winsock settings. This, in and of itself, is not terribly harmful, however, if it is not removed it may cause you to not be able to reach the Internet.
Some examples of New.net domain names are:
shop .xxx .club .ltd
.inc .travel .tech .sport
.family .law .med .mp3
It appears that NewDotNet is currently being distributed with eDonkey2000, IMesh, GDivx, NeoNapster and a few others.
