If you're using a modern version of Windows (likely since you mention antivirus software), boot into Safe Mode by restarting and repeatedly pressing F8 during startup. From Safe Mode, follow Microsoft's instructions to restore a previous system state:

  1. Click Start.

  2. Point to All Programs.

  3. Point to Accessories.

  4. Point to System Tools.

  5. Click System Restore.

  6. Follow the instructions on the wizard.

If you have Windows disks, try a repair install. This will replace Windows files without uninstalling applications or deleting data. –  CarlF Jan 30 '11 at 22:04

Try booting from the safe mode. Once there, uninstall your anti virus program. [change your anti virus !]. The update most probably has corrupted a file in the start up menu thus not allowing a full boot up.

This can can also be done from the command line but I am not sure of the correct programming so i cannot go further on that. If this fails try flashing the system thus making the notebook reset to factory settings etc but still retaining all programs.
