IE Killer is a security tool that helps you keep the integrity of Internet Explorer intact and make it less vulnerable to attacks from external threats (spywares, hijackers, etc).
IE Killer isn`t a program that fixes and repairs the problems that have caused the attacks. It just stops the processes that are running in Internet Explorer so they aren`t affected by the threats, and thus giving you time to repair and disinfect the browser.
For IE Killer to work correctly, you need to install NET Framework 2.0 or later.
