Melhores Antivírus e proteção contra malware (2026): nosso top 3 entre 16, em ordem

Nosso top 3 de apps de antivírus

The first two are close. Avast comes first because its free version gives a Windows PC real-time protection and a firewall, and it has free apps for Mac, Android and iPhone too. Bitdefender's free tier is Windows-only, but Total Security can be tried free for 30 days and its app averages 4.7 from about 38,000 ratings. Norton 360 is third for households that want a VPN, passwords and PC backup in one plan. McAfee narrowly missed: its app averages 4.7 from about 239,000 ratings, but its listing has no password manager or backup.

1. 1

   1º lugar: Avast

   Plano gratuito · a partir de $77.99/ano

   Para: Most people, and anyone who wants to pay nothing

   Avast Free Antivirus gives a Windows PC real-time file, behavior and web shields, ransomware protection, a firewall and network scans, and there are free Avast apps for Mac, Android and iPhone. Premium Security adds Bank Mode, Email Guard, a sandbox and webcam protection, for one device or up to 10. Know the limits: Avast's website refused automated reads when this listing was checked, so its paid prices are not listed here; check avast.com before buying. The VPN and Cleanup Premium cost extra unless you buy Ultimate, and some trials ask for a payment method.
