Kaspersky Internet Security 2021 is a powerful suite of malware-hunting, anti-hacker, web safety tools. 

There's antivirus. Browsing protection. A firewall. Exploit protection. A vulnerability scanner, parental controls, webcam and audio protection, online transaction protection, and more.

These features have real value, too. Independent testing labs such as AV-Comparatives typically rate Kaspersky as offering some of the best protection around.

There's the Software Updater, which checks for updates to common applications (Adobe Reader, Flash, Java, Chrome, Firefox, more), and can optionally install them without you having to see or do anything at all.

A "Secure Connection" feature is essentially a privacy-oriented VPN (virtual private network), automatically kicking in to protect you when using wifi hotspots, web banking sites and more.

An Installation Assistance tool looks out for adware and other pests that get silently installed with some "free" software, and the Software Cleaner helps you decide what to remove.


Kaspersky Internet Security 2021 is an excellent security suite with some worthwhile improvements and enhancements. It's still one of the best packages around.
