Having a few recent problems with system processes.

Hello.

I am having some severe peace-of-mind issues with a few unknown processes coming up in my Task Manager and a few small annoyances that have happened since they showed up.

My first, most major question is simply this:  Are Dell Data Vault Service and Dell Data Vault Wizard legitimate processes?  What do they do?  The former occasionally uses a small amount of CPU or disk space, nothing major.  The latter does not seem to go active, just sitting in the tray.  I have no pop-ups or open windows associated with these processes.

I also seem to be having some slight hiccups in a few programs ever since these processes appeared; Youtube videos occasionally hang a sound or jump slightly, and so do some other animations.  Again, nothing major, just enough to unsettle me.

I'm using a Dell Inspiron 7720 SE series
