Is mststub.exe malwere?

i was on local disk c: and i saw a very suspicious file i had never seen before called 0c7cf46a9fdea42afb0890ebf3, so i look what was in it and i saw an .exe file called mrtstub i went to properties to see if it was signed from Microsoft because i saw other questions about thismrtstub.exe file. while i was in properties i saw this under programs:

Cmd line:       C:\0c7cf46a9fdea42afb0890ebf3\mrtstub.exe

Working:                                                               

batch file:

Shortcut key:  None

and under font there is a picture that says:

c:\WINDOWS> dir

Directory of c:\W

SYSTEM              <DIR

WIN           COM        2

WIN           INI          1

WELCOM   EXE          1

so i think it might be  a batch virus but i am not sure so please help!!
