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.

System Changes

The following files have been added to the system:

  • %WINDIR%\system32\antiwpa.dll

    This patches winlogon.exe

    The following registry elements have been created:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows nt\currentversion\winlogon\notify\antiwpa\
    • asynchronous = 0
    • dllname = antiwpa.dll
    • impersonate = 0
    • logon = onlogon

    The following registry elements have been changed:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows nt\currentversion\wpaevents\
    • oobetimer = [binary data]

    These are general defaults for typical path variables. (Although they may differ, these examples are common.):
    %WinDir% = \WINDOWS (Windows 9x/ME/XP/Vista), \WINNT (Windows NT/2000)
    %SystemDir% = \WINDOWS\SYSTEM (Windows 98/ME), \WINDOWS\SYSTEM32 (Windows XP/Vista), \WINNT\SYSTEM32 (Windows NT/2000)
    %ProgramFiles% = \Program Files

    Removal

    AVERT recommends to always use latest DATs and engine. This threat will be cleaned if you have this combination.
