ClamAV vs Kaspersky Premium Total Security

ClamAV is a free, open-source antivirus engine for email and web scanning and endpoint security tasks. It provides a multi-threaded daemon, a command-line scanner and a tool for automated virus database updates. The database receives updates multiple times per day, and the updater supports scripted updates and digital signatures. ClamAV scans standard mail formats and many archive, executable and document formats, including MS Office, HTML, RTF and PDF. A Milter interface supports Sendmail. On modern Linux versions, ClamOnAcc can scan files when accessed, with an option to block access until scanning finishes. Signed signature databases limit execution to trusted definitions. The project lists GNU/Linux, FreeBSD, macOS and Windows as regularly tested platforms, and official Docker images are available for Alpine Linux and Debian Linux. ClamAV is an engine and associated tools, not a traditional antivirus or endpoint security suite. Recommended minimum resources are 3 GiB RAM, a 2.0 GHz CPU and 5 GiB of free disk space. The project does not guarantee extraction of every version or variant of supported formats.

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. Pricing starts at $54.99/yr; the 30-day trial converts to an automatically renewing yearly subscription unless cancelled.
