Both Kaspersky and CrySyS offer free Gauss online detection tools for windows users. Gauss is cyber surveillance malware that is designed to collect information about infected systems, as well as steal login credentials from banks, email, instant message accounts, and social networking sites.
Gauss is designed to collect information and send the data collected to its command-and-control servers. Information is collected using various modules, each of which has its own unique functionality:[ref]SecureList:Gauss: Abnormal Distribution. Retrieved on August 12, 2012[/ref]

The Kaspersky Lab Global Research & Analysis Team (GReAT) white paper state that Gauss was designed for 32-bit Windows operating systems, though some modules do not work under Windows 7, SP1. There is also a separate spy module operational for USB drives that are capable of collecting information from 64-bit Windows operating systems.[ref] SecureList[[/ref] Mac and Linux users are not affected.
