After spending hundreds, or even thousands of dollars on a brand new computer The best thing you can do is for it to get infected with malware. It’s vital to upgrade and test your antivirus software on a regular basis. The best antivirus software offers strong protection against malware, with a host of other internet security features. They include the use of a VPN, anti-phishing protection and password managers, dark web monitoring and parental controls.

The best antivirus software also is updated regularly, ensuring that the latest threats are detected and blocked. This is essential since new threats are developed constantly and old ones change over time to evade detection. Many of the top-rated antivirus programs come with a variety of methods to detect and block viruses, including signature detection, heuristic analysis behavior monitoring, sandboxing, and artificial intelligence.

A few of the top antivirus programs also include extra tools, such as a disk defragmenter for hard drives, a start-up apps manager, and a process monitor. This can help you keep your PC running at peak performance and protects against more threats than the basic malware scan that is offered by free antivirus programs.

Most premium antivirus software offers cross-platform and multi-device licensing that work with Windows, macOS, and Android. This makes it a great option for families with multiple devices or smartphones that require protection. Norton 360, for example, offers excellent security against viruses and malware together with a broad set of additional security tools, like a VPN and parental controls, as well as dark web monitoring, all at an affordable annual fee.
