While Shane will appreciate you purchasing the Pro version, it will not enhance the repairs.
You could open the program again in Safe Mode and use the registry back up option which will take you back to before the repairs, but I find the message about the repairs being recommended puzzling.
Does the laptop freeze with the mouse disconnected and just using the touchpad buttons and does the laptop still freeze with the mouse connected in Safe Mode with Networking ?
To get rid of the Ctrl+Alt+Delete logon - go Start - type netplwiz and press enter.
Under the Advanced tab and Secure logon, is the box checked for Require user to press Ctrl+Alt+Delete ?
If it is, uncheck it - Apply - OK and reboot.
When security programs fail to start, it can be a sign of infection, but did you get that error message before you ran Windows Repair ?
Can you go Start - type services.msc - press enter and check that the status of your services are as in this list - but don't download anything from there.
