Dell PowerVault DL4000 Recovery and Update Utility.

I never downloaded this program (to my knowledge at least) however, the laptop recognized it as legitimate and a virus scan picked up nothing. Does anyone has any idea where this program came from?

Had to reinstall windows xp and now I have No sounds,can not get on the internet all icons are no longer there except my trash can icon. With the CD's that came with my dell dimension 9100 Which do I use to get back whats not there?
