Do I really need antivirus software anymore?

The honest answer surprises people who grew up buying antivirus subscriptions: for most users, the built-in protection is now enough, and paying for a heavy third-party suite is often unnecessary. Windows includes Microsoft Defender, which has gone from a punchline to a genuinely capable antivirus that consistently scores near the top in independent testing, runs quietly in the background, and updates automatically, so a typical Windows user who keeps the system updated does not need to buy anything extra. Macs have strong built-in protections and a much smaller malware target, and phones, with their locked-down app stores, rarely need antivirus at all. The once-standard advice to install a paid antivirus on every device has largely aged out.

There are still cases for more: people who frequently download risky files, run older systems, handle sensitive work, or want extra features like a password manager, VPN, or parental controls bundled in may reasonably choose a reputable paid product, though many of those features can be gotten separately. What matters more than any software is behavior, because modern threats increasingly bypass antivirus entirely by targeting you: phishing emails, scam pop-ups, fake tech-support calls, and malicious downloads that trick you into installing them. No antivirus reliably stops a user who is talked into handing over a password or clicking install. So the priorities, in order: keep your operating system and browser updated, use strong unique passwords with two-factor authentication, stay skeptical of unexpected messages and links, and let the solid built-in antivirus do its job. Avoid the sketchy free antivirus programs and aggressive pop-up your PC is infected products, which range from useless to malware themselves.
