Description
A common distribution method for adware and spyware is to have the user download an executable file and run it automatically from the Downloaded Program Files folder. This rule is specific to Microsoft Internet Explorer and prevents software installations through the web browser. Internet Explorer runs code from the Downloaded Program Files directory, notably ActiveX controls. Some vulnerabilities in Internet Explorer and viruses place an .exe file into this directory and run it. This rule closes that attack vector.
