最佳杀毒与恶意软件防护（2026）：我们从16个里排出的前3名

我们评出的杀毒软件前三名

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

   第一: Avast

   免费套餐 · $77.99/年起

   适合：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.

   第二: Bitdefender

   免费套餐 · $49.99/年起

   适合：Households that want a paid suite across every device

   Bitdefender Antivirus Free gives a Windows PC real-time malware and ransomware protection with no time limit, and paid plans cover Windows, Mac, Android and iPhone. Total Security is $59.99 the first year for 5 devices, then $109.99, with a password manager, and refunds run for 30 days after a purchase or a renewal. Its iPhone and iPad app averages 4.7 from about 38,000 ratings. It is second because the free version runs on Windows only and needs an account, and the VPN stops at 200 MB a day below Premium Security.
