Could You give me confirmation that FType2K.exe have malicious code?

When we'll get an answer from lab, we shall inform you.
For now, i can say it needs newdll.dll to run.
And newdll.dll act like a keylogger, we would like to see it.Keylogger ability can be used in different friendly programs, but if you can live without such programs that using this kind of technology- it is much safer in my opinion.
Because, if this program become too popular, bad guys can use "friendly" keylogger and may create some little application in order to get information from friendly keylogger (that you are trust).
advantages to bad gues:
* no need writing and installing keylogger to victim ( it is already installed by user)
* better hiding ability from antivirus/hips(cause their application will not going to do any suspicious things like a keylogger itself )

Here script in order to copy:

begin
clearquarantine;
SearchRootkit(true, true);
SetAVZGuardStatus(True);
 QuarantineFile('C:\WINDOWS\system32\newdll.dll','');
BC_ImportAll;
BC_Activate;
RebootWindows(true);
end.
