Avast Premium Security review

Avast is the easiest way to try well-regarded antivirus for free and then pay only for the scam tools you need. Avast Free Antivirus earned AV-Comparatives' Top-Rated Product 2025 and AVLab's Product of the Year 2026, according to Avast, and Premium Security uses the same protection. The paid tier adds alerts on suspicious emails, blocking of scam SMS messages and calls through the mobile app, and Avast Assistant, an AI tool that checks whether a message or offer looks like a scam. The 1+1 offer pairs one Windows PC or Mac with one mobile device for $49.08 in the first year, and a 10-device plan costs $69.48. The catch is renewal: the single-device plan returns to $77.99 per year, more than Bitdefender or Malwarebytes charge for 3 devices. Windows users can try it for 30 days without a credit card, and Mac users get 60 days.
