Overview:
NewDotNet is a browser hijacker and can update itself without any input from you. Anything that modifies your windows HOSTS file is a hijacker and we don't want it! The "purpose" of this is to add support for additional domains like .AGENT .INC .LOVE .SHOP .SPORT. We suggest you remove this.

This junk has become common enough for MS to address it!

There is an option under the add/remove programs list. You should see something called New.net Application or New.net Domains remove it that way. If that fails they have an additional uninstall utility available here. Make sure you do both of these before proceeding or else you could end up having quite a few issues with your browser!

Also Known As:
New.Net
Dialer-RAS.aj
NewDotNet/B

Destroy Autorun:
Delete the following keys
HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run\new.net startup

Reboot your system then:

Make sure you click start --> Run and type in msconfig. Then select the startup tab. Any references to the processes below should be deleted

Unregister DLLs:
Tip: this is only a list of known files/locations. You will want to do a search by the name of the file to see if they're on your system.
A while back I wrote a guide to Register/remove DLL or AX files which you will need if you don't know how to unregister these files.

Each file is in several locations so you'll need to search for them and unregister + delete them in every location you find.

newdot~1.dll
newdot~2.dll
newdotnet3_36.dll
newdotnet3_70.dll
newdotnet3_88.dll
newdotnet4_50.dll
newdotnet4_85.dll
newdotnet4_88.dll
newdotnet5_20.dll
newdotnet5_48.dll
newdotnet6_22.dll
newdotnet6_30.dll
newdotnet6_38.dll

Folders to Remove:
%program_files%\newdotnet

You should be back to normal IF this was your only problem. I suggest you post in our HJT forum since its not likely that this is your only bug. Read this first
