installed on its host.
This rule should detect
Many corporations and individuals view this type of adware/user profile
software a policy violation by their end users. This type of software is
also generally thought of as 'spy-ware' by the way sends data about your
surfing habits to a third party without the direct knowledge of the end
This rule looks for a generic POST accompanied by the presence of a .dll

A website tricks the end user into loading this software, or this software
can be coupled with other software installing itself silently on your
