I happened across this website as I was searching desperately for a strategy to end the ntsearch invasion of my computer.
The intrusion has been crushed by means of a simple link on their website to "uninstall". And I only dared to punch that button after using spyware scanners/cleaners to make sure there are no bad goings on . .. so... so far so good and all my html pages are clean again.
Oh... and I happen to be also a musician! :-)
