Got my Dell laptop about a week ago with Vista-64 bit. Its been working relatively well except for one thing. Whenever I go to control panel to try and change startup programs I keep getting a window popping up labeled Windows Defender that says "Application failed to initialize: 0x800106ba..." I know Windows Defender has problems running with McAfee so I disabled windows defender but I still get this popping up. Anybody know of anyways around this besides disabling McAfee? Thanks.
