SeaerchForIt.AdShooter is a toolbar that installs itself on Microsoft Internet Explorer as a BHO (browser helper object) in order to avoid detection by the Windows firewall and most anti-spyware programs.

SearchForIt.AdShooter creates pop-up ads, many of which link to ClickBank.net.  You can get rid of this nuisance by deleting the files listed below.  A free scan with SpyZooka will alert you to any other threats that might be hiding out on your computer.
