Hi Lori, My gut reaction is to say that you are in the clear. Having received a clean bill of health from both Security Essentials and Malware Bites, I think you've performed due diligence. When your computer unexpectedly shut down, do you know which program informed you about the "unauthorized shutdown?" Was it a general Windows message that came up upon restarting, or was it generated by Security Essentials? If you still feel uncertain about the security of your system, you can run a complete scan using security essentials. The default scan is a quick scan. To do this, open security essentials from the start menu or from within the system tray. Once the program has focus, use tab to locate a set of radio buttons which will offer you the choices of quick, complete, and custom. Use up/down arrow to locate complete, then tab to and select the scan button. Let us know how you fare, or if we can help further.
