Does Antivirus Still Matter in 2026?
Yes. Windows Defender has improved significantly, but it still misses zero-day threats that third-party antivirus labs detect faster. MacOS is not immune either. If you download files, open email attachments, or use public networks, dedicated antivirus catches what the OS misses.
We tested McAfee, AVAST, and ESET across detection rates, system performance impact, and extra features. Here is the breakdown.
McAfee: Best for Families
McAfee bundles more features than either AVAST or ESET at the same price point. You get real-time malware scanning, identity theft protection that monitors dark web databases for your personal information, a built-in VPN, and parental controls on family plans.
The identity monitoring is the standout feature. It scans for your email addresses, Social Security number format, and financial account details in breach data. When something turns up, you get an alert and guidance on what to do.
The downside is resource usage. On older hardware, McAfee's full scans can slow the system noticeably. If your PC is less than three years old, you will not notice. On a seven-year-old laptop, you will.
Pricing is $39.99/year for up to 5 devices.
AVAST: Best Free Starting Point
AVAST offers one of the best free antivirus tiers available. The free plan includes real-time virus scanning, a Wi-Fi inspector, and basic ransomware protection. There is no time limit, unlike some competitors that offer a free trial that expires.
The paid plans (starting at $35.88/year) add a built-in VPN, advanced ransomware shields, and unlimited VPN data. The VPN is basic compared to a dedicated service like NordVPN, but it covers public Wi-Fi encryption adequately.
The tradeoff: the free version shows ads and upgrade prompts. If that bothers you, either upgrade or choose a different product.
ESET: Best for Gaming PCs and Power Users
ESET is the lightest antivirus we tested. During our test, ESET used roughly 0.1% CPU at idle and completed background scans without any noticeable performance impact during gaming sessions. McAfee used 0.4% at idle and AVAST was similar.
For anyone who games or runs CPU-intensive software, that difference matters. ESET's UEFI scanner is also unique: it checks your PC's firmware for threats that load before Windows even starts. Most consumer antivirus products do not scan at that level.
The interface looks like it was designed in 2018, but every feature works reliably. You get what you need, without the bundle bloat of McAfee.
Pricing is $39.99/year for one device.

Which One Should You Get?
Get McAfee if you want an all-in-one security suite for your family. The identity monitoring and parental controls add genuine value for households.
Get AVAST if you want a free start. The free tier covers basic protection, and you can upgrade later if you want the VPN bundle.
Get ESET if you game, edit video, or run anything resource-intensive and need antivirus that stays out of your way. It is also the best pick for advanced users who want granular control over scan settings.
