The spyware requests several files during installation and sends IP and operating system version information to a server. This spyware comes bundled and installs Spyware.Shopnav.

Programs that have the ability to scan systems or monitor activity, and relay information to other computers or locations in cyberspace. Among the information that may be actively or passively gathered and disseminated by spyware are passwords, log-in details, account numbers, personal information, individual files, or other personal documents. Spyware may also gather and distribute information related to the user's computer, applications running on the computer, Internet browser usage, or other computing habits.

Spyware frequently attempts to remain unnoticed, either by actively hiding or by simply not making its presence on a system known to the user. Spyware can be downloaded from Web sites (typically in shareware or freeware), email messages, and instant messengers. Additionally, a user may unknowingly receive and/or trigger spyware by accepting an End User License Agreement from a software program linked to the spyware, or from visiting a Web site that downloads the spyware with or without an End User License Agreement.
