Avast Internet Security has one of the strongest antivirus software available. It provides real-time protection against a wide range of threats including viruses, spyware, and ransomware. It includes other features like a firewall, spam filtering and a secure browser.

The malware engine of the program earned a perfect score in my tests, and was able at detecting a wide range of dangers, including ransomware rootkits, cryptojackers, and sites that are phishing. Its web security is also top-notch, catching websites that are phishing, but aren't detected by Chrome or Firefox's default security. The firewall is a layer of protection that prevents hackers from accessing devices, regardless of whether or not they are connected to your home network.

Avast's privacy tools come with the free Avast SecureLine VPN, which secures your connection and safeguards you from public Wi-Fi. It also blocks invasive trackers and provides additional protection against spyware. The Password Manager allows you to safely store and manage all your passwords. This can be a major issue for cybercriminals seeking to steal your passwords.

Avast's user base is highly loyal, so the company can charge a slightly higher price for its software than its competitors. It's nevertheless important to ask any company that gathers your personal information on how they intend to use it prior to you sign up. Which? will be in 2020. Which magazine found out that Avast sold information on the websites of its customers. The company later apologized for this privacy breach.
