Should I Turn my computer off?

You do not need to turn your computer off when you are not using it.*  It is actually better to leave your computer on when you are not using it so that your software such as windows, antivirus and other programs running on your machine can continue to update and keep you protected. 

*One exception would be extended periods - days, weeks, and longer periods where you do not plan to use it.  When it is powered back on and connected to the internet, it will pickup where it left off .
