Most free antivirus programs provide basic protection from viruses and different types of malware. Real-time protection is common among the best free options. Some even offer free extras such as ad blocking, a firewall, or VPN. However, paid antivirus tools tend to have more advanced protection such as ransomware protection.

With a paid antivirus plan, you’re likely to find more extra features, some of which will be less limited than their free counterparts (an unlimited data VPN, for example). Another key difference is that paid antivirus solutions tend to offer direct customer support, be it via live chat, email, or phone. Free versions are typically limited to FAQs and forums in comparison.

The best antivirus software provides protection against viruses and malware. Indeed, you’re far better off with one of these antivirus tools than without. This is due to the fact that Windows 7 is no longer supported by Microsoft. As such, new vulnerabilities aren’t patched as they’re discovered. The best free antivirus programs for Windows 7 should be used alongside safe browsing practices, regular data backups, and additional security tools.
