windows 7 system help

Hi everyone, I recently got a bad virus which deleted dinotify.exe from my computer. and I contacted microsoft about this. They told me t get it from another windows 7 computer, so here I am, with no functioning USB devices, in need of this file.

Does anyone have dinotify.exe (located in system 32) for windows 7 32 bit home premium edition?

why not do a system restore back to before the virus?
