Characteristics

This software is not a virus or a Trojan. It is detected as a "potentially unwanted program" (PUP). PUPs are any piece of software that a reasonably security- or privacy-minded computer user may want to be informed of and, in some cases, remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, or the privacy posture of the user of the system, such that most users will want to be aware of them.

    • Removal

    All Users:

    Please use the following instructions for all supported versions of Windows to remove threats and other potential risks:

    1.Disable System Restore (Windows ME/XP only).

    2.Update to current engine and DAT files for detection and removal.

    3.Run a complete system scan.

    Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

    General repair may be unsuccessful in some instances. If this occurs, please submit a sample for further evaluation.
