Kaspersky has one of the most feature-packed, and also the best antivirus software in the market. The Kaspersky security cloud free is an update of the Kaspersky free AV and looking at what it has to offer, it indeed is an update.

Gamers will love it even more because it also includes a gaming mode to prevent notifications, and other interruptions.

Where most free antivirus software outright deny users password management, Kaspersky allows free users up to 15 password entries, and a limited-usage VPN.
