Avast: Free Antivirus Software Guide
Avast offers a popular free antivirus for Windows, Mac, and mobile. Paid tiers add more features. This guide covers what Avast offers and what to consider.
Free and popular
Avast's free tier has been used by millions. It provides core antivirus and basic protection. Paid plans add privacy tools, VPN, and advanced features. The company has faced criticism in the past over data and upsells; review the current privacy policy and product behavior if that matters to you. For a free antivirus that's widely used, Avast remains an option; for open source or a different vendor, consider Bitwarden (passwords) or Malwarebytes (malware focus).
