Characteristics

McAfee(R) AVERT recognizes that this program may have legitimate uses in contexts where an authorized administrator has knowingly installed this application. If you agreed to a license agreement for this, or another bundled application, you may have legal obligations with regard to removing this software, or using the host application without this software. Please contact the software vendor for further information.

See http://vil.nai.com/vil/DATReadme.asp for a list of Program detections added to the DATs.

See http://vil.nai.com/vil/pups/configuration.htm for information about how to enable, disable, and exclude detection of legitimately installed programs.

Distribution

This is not a virus or a trojan. It is detected as a "potentially unwanted program." It is a direct-marketing adware application that generates pop-up advertisements. A DLL is installed as Browser Helper Object in Internet Explorer, and may also be injected into the explorer.exe and winlogon.exe processes. Context-based advertisements are displayed as the user browses the web. A unique identifier is created for the system during installation. This identifier is transmitted during retrieval of advertising content.

Example of an advertisement displayed after searching for "home refinancing" on the Google homepage:

This application does not display a license agreement when installed.

Privacy

A privacy policy is not displayed during installation. Possible privacy implications exist due to the use of a unique identifier and keywords to retrieve context-based ads during browsing.
