try it
EDIT: yep, it's the password.
It creates two files
C:\DOCUME~1\<USER>~1\LOCALS~1\Temp\ytmp\tmp33507.bat (successful)
C:\DOCUME~1\<USER>~1\LOCALS~1\Temp\ytmp\tmp95157.exe (successful)
and then runs them.
i opened the .bat in Notepad++ and stole the password from there (which probably isn't the legit way of doing so but oops) but hey it werks, no clue what the .exe is though. using the password and then the program on the "password.mdft" file decrypts it and writes a new file called "passwordDecrypted.mdft" containing this:
50617373776F72643A204266386D69397830306638
unfortunately, this is not the password to the file in the included songs.rar.
i don't think this is a virus, though.
