NetZero Toolbar – X1IEBHO.EXE
X1iebho.dll is the browser helper object that installs with the NetZero, NetZero Platinum, ZeroPort or Juno Toolbar. This toolbar installs when you sign up with any of the United Online, Inc ISPs including NetZero, NetZero HighSpeed, BlueLight, or Juno. If one of these is your ISP, we'd recommend against removing this file. NetZero states that it can't be minimized, moved off screen or placed in the background while connected.
