It uses machine learning to detect unknown threats and includes anti-ransomware, web protection, privacy firewall, and vulnerability assessment. The suite covers Windows, macOS, Android, and iOS.

Kaspersky
Kaspersky consistently achieves top marks in independent malware detection tests alongside Bitdefender. Its technology is widely respected in the cybersecurity community.

In 2024, the US Commerce Department banned Kaspersky sales in the US. Despite the political concerns, the underlying technology remains among the most effective antivirus solutions available.
