I an unable to update Microsoft Security Essentials. I am running Windows 7 Ultimate 64-bit. When I expand the error popup box by clicking the "Support information" arrow it shows "Error code: 0xc80003f3". I researched this and the only thing I can find is that it is a memory error but my system has 3GB RAM and an ample pagefile (manually set and doubled the Windows "reccomended size") I am running a sidebar gadget that shows 44% RAM used so I'm not sure what is happening. The Windows update will not update either and shows the same error (8xc80003f3)in the event logs for the WindowsUpdateClient.
