Microsoft Defender vs McAfee
The antivirus already on your PC against a paid suite for the whole household. The first one is free, and that is not the weakest argument here.

What year two costs
On the vendors’ own pages: Microsoft Defender has no subscription and nothing to renew (read September 30, 2026); McAfee+'s page could not be verified on October 6, 2026, so no amount is quoted for it. Across the 7 vendors that print a renewal price, the median increase is 33.3% and the average 42.2%; every vendor with its source is in the Renewal Price Index, and the entry prices of both sit side by side in the Price Index.
Our verdict
Microsoft Defender wins for most single PC users and McAfee wins for households with many devices. Defender is built into Windows, costs nothing, and scores 4.2 here. McAfee Premium scores 4.0. com. That is the uncomfortable summary. The free one scores higher.
Defender has been a competent product for years and is deeply integrated into Windows, which means no extra process, no upsell popups and no subscription to forget. What McAfee adds is coverage across everything in the house. Phones, tablets, Macs, plus identity monitoring and a VPN. Defender does not follow you off Windows.
The honest downside of Defender is that it is Windows only, has no identity monitoring, and its extras are thin compared with a paid suite.
The honest downside of McAfee is the renewal, since the first-year price is an introductory rate that rises at renewal, and the software is noticeably heavier on the machine than Defender. One careful person on one Windows PC should keep Defender and put the money somewhere else.
A family with phones and laptops across platforms should take McAfee, or a paid suite with a higher score.
“The free baseline that made half the paid market nervous. A perfect 6/6 protection score in recent AV-TEST rounds, zero nags, zero installs. It lacks a VPN, password manager, and cross-platform coverage, but for a careful single-PC user, Defender plus good habits is a legitimate choice.”Editorial team, on Microsoft Defender
“Unlimited devices on one plan is McAfee’s trump card, and the identity pivot is real. Credit monitoring and identity insurance are now the core product. The scanner is solid, but the constant upsells and a renewal price that triples make this a deal only at first-year prices.”Editorial team, on McAfee+
Frequently asked questions
Is Microsoft Defender enough on its own?
For a careful user on a single Windows PC, yes. It is built in, free, and scores 4.2 in our editorial rating, higher than McAfee at 4.0. Where it falls short is outside Windows and outside malware. No identity monitoring, no cross platform cover, no VPN worth the name.
What does McAfee add that Defender does not have?
Cover for phones, tablets and Macs, identity monitoring and a VPN, all under one subscription. McAfee's site blocks our price checks, so the current price is on mcafee.com rather than in the table above. Defender protects the Windows machine it lives on and nothing else. If the household has devices on three operating systems, that is the whole argument.
Does McAfee slow down my computer?
More than Defender does, yes. Defender is part of Windows and shares its resources, while McAfee runs its own services on top. On a recent machine you will barely notice. On an older or low powered PC the difference shows during scans and at startup.
