Are you talking about the systray instead and not the task bar? The systray is over by the clock. If the program is there, you should be able to turn it off and stop it from running at startup by using:
type in "msconfig" (no quotes)
Then find it in the startup group of programs and untick it. I'm assuming you don't need it running in the background all the time.
Otherwise, I'm thinking you might need an application to hide (from other users) folders or files that are in use by you.
