The remote host is running client software which may be considered questionable
The remote host is using the ALEXA program. This software is bundled by default with Internet Explorer 6. This software transmits the complete URL of the search results to both 'msn.com' and 'alexa.com', thus potentially violating the privacy of the remote user. You should ensure that the user intended to install ALEXA and that the use of ALEXA matches your corporate mandates and security policies.
Remove the software manually.
