This backdoor Trojan program comes from Germany and the name of its author is Umbra.  Umbra created this menace back in October of 2001 and it is written in Delphi language.

Once Win32.Nakter is inside, it will drop this file into your registry:
C:WINDOWSSYSW32.EXE and then it will leave the following fingerprints:
2a878aa250f5827f…
1a61e6066475a62c…
405a7a69e0049ced…
65774f7e20a45dcf.

If you happen to notice some strange behavior on your PC such as applications running on their own or your mouse leaving trails then you may have a Win32.Nakter infection.
