I used tutorial85.html from this site to help remove CWS_NS3 "Home Search Assistant Hijacker". I think at least one of the other "removal tools" was actually a SpyWare installer itself [one of them had a name ending in "shredder", I can't dell if it did more damage than good], so be careful if you have this hijacker; at least "bleepingcomputer" doesn't seem to have it's own unwanted payload.
Though it seemed useful, AboutBlaster hacked my IE start and search pages to http://www.google.com/, which I did not appreciate.
I needed to do more than just the steps shown, so the hijacker has probably been updated since the tutorial and since the latest version of AboutBlaster. None of the tools I used (NAV, Spy Sweeper or About Blaster) did the whole job themselves.
The latest rev of SpySweeper discovered the hijacker but its running processes brought it back.
Since the author put most of their pages in \WINNT as hidden files, toward the end it was pretty simple to do a >DIR /ah /od to find them.
Getting rid of all the background processes was the hardest, as I have a bunch of legitimate "O4" processes running. I couldn't tell about "javabn.exe", and left it in the first few passes, but I eventually zapped it.
The last things to go were appcv.exe, some unwanted Favorites entries, and last of all, a startup entry for msyt32.exe (which didn't exist by that time).
I hope this will be helpful to somebody else; you can put back the start and search pages in REGEDIT by searching for Google, so the "damage" from AboutBlaster, though annoying, was easy to address (it would have been easier if I knew it was going to happen; it took a few passes to realize that AboutBlaster was doing it).
