Internet Explorer Disable or Uninstall Fix It tool

Hi,

While running JavaScript through Internet Explorer 8, I was getting alert: "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?"

I searched for this problem and installed Fix it tool from

http://support.microsoft.com/kb/175500

I am not able to find out from where to disable Fix it utility. This utility has been also applied to my AOL browser. Plese suggest any way to disable this.

I am not an administrator of system.

Cheers,

Pratima
