Dialybackup.VBS is a visual basic script file, which is being executed each time your windows starts, since it's in Start Up folder.
And by the spelling of "daily" in given file, it clearly indicates a malware, and not any genuine backup program. (D
ialybackup.VBS)
Try rhitwick's method above to remove the program from starting up.
Also, I would be curious to know what did you do, to infect a (possibly) fresh install of Windows 7, since this version of windows is not so easy to get infected.!
