Without up-to-date software, the average unprotected computer connected to the Internet can be compromised in less than a minute. So, the single most important step to securing your computer is making sure you always have all the current updates to key software packages installed. This includes your operating system, web browser, email program, all other applications that connect to the network, and Microsoft Office.
You can configure your computer to automatically run Windows Update or the Mac OS Software Update daily.
