Avira vs Comodo Internet Security (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 Comodo Internet Security if

• Fits if you want a free antivirus and firewall on a Windows PC
• Works for a home user who wants a sandbox for unknown files

Look elsewhere if

• Skip it if you use a Mac, phone or Linux, as it's Windows only
• Watch out: the pages list Windows 10, 8 and 7 and look dated, so check current support before buying
• Watch out: the homepage leads with website and enterprise products, with consumer security further down
• Watch out: the virus-free guarantee covers up to $500 in repair costs for US customers only

Avira
