Dumb question: WTH does "locked down" mean?
It means its like the equivalent of Fort Knox - no one can get in unless you allow it. So when you install that registry patch - IE Spy-ad you're letting the bad guys know your computer is off limits. I went to Coolwebsearch and nothing happened. That's how effective this particular piece of condom software is in shutting down the scumware pushers' abilities to install unwanted software via drive by downloads behind your back.
