Avira Free Antivirus vs Comodo Internet Security

Avira Free Antivirus is a freemium internet-security product for Windows, macOS, Android, and iOS. Its Free Antivirus plan costs nothing and includes 500 MB of VPN data per month. The product combines real-time malware monitoring with ransomware protection, a password manager, privacy settings optimization, browser protection, Safe Shopping, PC tune-up tools, and Software Updater. Avira describes coverage for ransomware, spyware, adware, phishing, and zero-day attacks. Detected files can be deleted or quarantined. Browser Safety can block harmful ads and pages and prevent online tracking. The free version uses the same scan engine and cloud-based detection system as Avira Antivirus Pro; the paid version adds signature-based and heuristic analysis and advanced web protection. The free plan is for private, non-commercial use. Free users can seek help from Avira’s worldwide community, while support requests require an Avira license. Avira states it does not sell user data or share it with government, Big Tech, or advertising networks.

Comodo Internet Security is a Windows security suite that combines antivirus protection, a packet-filtering firewall, host intrusion prevention, and automatic isolation for unknown files. Its Auto Sandbox runs unfamiliar files in a separate environment. The firewall can block unauthorized inbound and outbound connections, manage which programs can access the internet, and hide computer ports. Secure Shopping isolates browser sessions and includes keylogger prevention, screen-capture blocking, and SSL certificate inspection; it can also run applications such as email clients, password managers, spreadsheets, and VPN clients in that environment. The product describes cloud antivirus scanning, behavior analysis, and whitelisting, alongside malicious-website filtering with custom block lists. Comodo lists a free plan and paid plans from $29.99/yr. Its guide lists Windows 10, 8, and 7, and says versions 12.0.0.6882 and later do not support Windows XP or Vista. Support resources include Comodo Support, an online help guide, and a user forum.
