Kaspersky Premium Total Security vs KnockKnock

Kaspersky Premium Total Security combines antivirus, privacy and identity protection, performance tools, an unlimited VPN and a password manager. Its multilayered protection addresses malware including fileless attacks and rootkits, plus ransomware, phishing, malicious sites, infected ads, credit-card skimmers, firewall threats and cryptojacking. Online Payment Protection opens a protected browser for transactions. The VPN encrypts public-Wi-Fi traffic and hides the IP address. Identity Theft Check looks for phone numbers in data leaks, while Data Leak Checker checks email exposure. The password manager stores synchronized passwords in an encrypted vault and warns about leaks. Safe Kids is included free for one year with location, website and usage controls. Utilities cover storage cleanup, drive-health monitoring and app-update alerts, with Windows speed-up features. It supports Windows, macOS, Linux, Android and iOS, with a three-device limit.
