Internet security is a subset of computer security that includes a number of security methods to guarantee the safety of operating systems, other programs, networks, and browsers. Since the majority of malware programs and cyberattacks start online, the main objective of the Internet security suite is to provide guidelines and policies to prevent online cyberattacks.
What is Internet Security Software?
Internet security software is a special program that keeps your online world safe. It can:

This feature checks everything while you browse or download. It works all the time to stop new threats as they pop up.
