Hi Mike,
First try reboot your machine, in case an update required a restart.
If that doesn't fix the problem, the next step would be to go to the task manager (Ctrl/Alt/Del) and go to the processes tab. Scroll down to QBW32.exe, highlight it and then click End Process (at the bottom right), then click file and exit.
Restart quickbooks from the icon by right clicking and clicking open. Do this only ONCE, hit it more than once will make Quickbooks attempt to start multiple times. Give the program time to launch.
If this doesn't work find the reboot.bat file (do a search for this if you can't find it in the quickbooks folder) - double click on it to run it. Once that is complete try again to restart Quickbooks.
If you are still having trouble you can try a a repair of quickbooks (2006 and higher). Go to the Control Panels, add remove programs, scroll down to quickbooks and click on Change remove button, choose the repair option.

If this doesn't work, you will need to do a clean install - (be sure to copy your quickbooks files to a remote disk or into another file (my documents would be a good place to put them if you have to put them on your hard drive) - If you get to that point ask about doing a clean install and I will be happy to walk you through it -

Spybot has been known to damage the QuickBooks program in the past.
You will need to reinstall the program.
