Avira vs ZoneAlarm (2026): which should you pick?

Pick Avira if

• Fits if you want antivirus, a cleaner and a password manager on a Windows PC for free
• Works for Android users who want a free scanner with app locking

Look elsewhere if

• Skip it if you use a Mac, as there's no Mac app on our record
• Tight if you stream over the free VPN, which stops at 500 MB a month on Windows and 100 MB a day on Android
• Not for you if you want web protection or camera and mic blocking free on Android, as they're Pro features
• Watch out: the iPhone app's listing mentions no virus scans, only a VPN, web protection, breach checks and call blocking
• Watch out: we have no prices on record, as Avira's site refused our reader, so check avira.com before buying

Pick ZoneAlarm if

• Fits if you want a free firewall or antivirus on a PC
• Works for someone who wants one paid suite across PC and phones

Look elsewhere if

• Skip it if you want to compare prices first, as none could be read
• Tight if you stay on the free downloads, which cover PCs only
• Watch out: threat emulation and mobile protection are only on Extreme Security
• Watch out: products other than Extreme Security list fewer platforms

Avira

• Avira's website and help center refused automated reads on 2026-10-17, so its plan prices are not listed here; check avira.com before buying.
• The free VPN stops at 500 MB a month on Windows and 100 MB a day on Android; unlimited VPN needs a paid plan.
• The iPhone app offers a VPN, web protection, email breach checks and call blocking; its listing does not mention virus scans.
• On Android, web protection and microphone and camera blocking are Pro features; the scanner, VPN allowance and app lock are free.

ZoneAlarm

• Plan prices are not recorded: the product and pricing pages answered with a bot check, so nothing could be read.
• The home page lists Extreme Security NextGen for Windows, macOS, Android and iOS; the other products list fewer platforms.
• Threat emulation and the mobile protections are listed only for Extreme Security.
