I recommend running LSP-FIX anyway, we want to make sure this beast is gone forever.
Here is more info on removing new.net, you have already done some of this but no harm in checking again:
Please download LSP-Fix from the following link and save it to a location you can find later if necessary.

To remove New.net please follow these steps:
[*]Click on start, then settings and then control panel.[*]Double-click on the Add/Remove Programs icon.[*]Look through the installed programs for a program called New.Net or NewDotNet.
If there is no uninstall program listed then do the following:[*]Go to
www.newdotnet.com/removal.html [*]Scroll down to Procedure 4 and follow the removal instructions.[*]Once the computer has rebooted, start HijackThis and fix any of the corresponding entries for that program that are found.
Then reboot and delete the C:\Program Files\NewDotNet\ directory.
At this point you should be clean.
