Avast antivirus offers a comprehensive set of features packed into a compact package. Its malware engine got an impressive score in my testing, and its web protection was effective in identifying sites that were phishing that slipped through Chrome and Firefox’s default detection systems. Its performance scanner performed well in keeping its impact on speed of the system to minimal. In fact, Avast’s performance scanning proved more efficient in reducing the use of CPU than any other program I tested.
Avast also provides a variety of other tools. It includes a password management tool and an VPN (exclusive to Avast One), a photo vault, and a data breach monitoring feature. Its security toolkit also includes a sandbox for running applications and a router scanner to check for vulnerabilities.
