A program or set of programs which hides itself by subverting or evading the computer's security mechanisms, then allows remote users to secretly control the computer's operating system.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Rootkit:W32/Kobchka is a Generic Detection that identifies files with rootkit-like characteristics or behavior. About Generic DetectionsUnlike more traditional detections (also known as signatures or single-file detections) a Generic Detection does not identify a unique or individual malicious program. Instead, a Generic Detection looks for broadly applicable code or behavior characteristics that indicate a file as potentially malicious, so that a single Generic Detection can efficiently identify dozens, or even hundreds of malware.
For more information about Generic Detections, see the Other:W32/Generic description.
