OS Updates
Each operating system (OS) has its own unique vulnerabilities. People take advantage of these vulnerabilities to spread viruses and worms, which can cause damage and harm to your computer when it is unpatched or unprotected. We highly recommend keeping your computer up to date with all OS updates. Microsoft and Apple have included an autoupdate feature with recent version of their operating systems.
