It appears that your computer has a program called CommonName installed on it. This program is bundled with certain applications, including several music sharing programs, and is installed by default.
The newer variant CommonName/Agent periodically opens pop-under advertising as well as highjacking search settings. It may also introduce browser stability issues. Because of this, and privacy violation issues with CommonName/Agent, which uses cookies to identify you when requests are made to CommonName, your web usage may be tracked. Requests are made when advertising is opened and when you visit a web address with a top-level-domain that the CommonName software does not know about. This includes .edu and .mil sites.
Because of the above issues, and the fact that numerous campus web sites may not work when you have this software installed, possibly including network registration, we recommend that you uninstall this software from your computer. Doing so will not effect the functionality of the application with which CommonName was bundled, e.g. KaZaa, iMesh, etc.
