I get asked this question at least once a week, usually while I am cleaning an infection off a computer that already had antivirus on it. So let me answer it the way I would in your kitchen.
Short version: of the three names everyone knows, Malwarebytes is the best by a wide margin. Norton is decent software wrapped in an upsell machine. McAfee is the one that came free with your laptop and has been nagging you ever since. And none of the three is what I would put on a computer I was responsible for keeping clean.
Here is the longer version.
What antivirus is actually supposed to do in 2026
Twenty years ago, antivirus was a list of known bad files. If a file matched the list, it got blocked. Every vendor had a list, and the good ones updated it fast.
That model is mostly dead. Modern attacks do not arrive as a recognizable virus file. They arrive as a phone call from "Microsoft," a fake Chrome update, a Word document that runs a script, a legitimate remote-access program that a scammer talked you into installing, or a login stolen from a data breach. Nothing on that list matches a signature.
So a good security product today has to do three things:
- Block known threats (the old list, still useful)
- Catch bad behavior even when the file is new: a document launching PowerShell, a program encrypting hundreds of files, something reading your saved browser passwords
- Tell someone who will act on it
Consumer antivirus is built for number one, has gotten better at number two, and has never done number three. Keep that in mind as we go through the brands.
Norton 360
What it does well. Norton's detection engine tests well. It consistently scores near the top at the independent labs (AV-Test and AV-Comparatives), and it has for years. If you want a big-name product that will catch known malware, Norton will do it.
What drives me nuts. Norton is not sold as antivirus anymore. It is sold as a "360" bundle: VPN, password manager, dark web monitoring, cloud backup, parental controls, and a steady stream of pop-ups offering you the next tier. At one point Norton even shipped an opt-in cryptocurrency miner inside the product. The first-year price is attractive, and the renewal is not. People are regularly surprised to find $100 or more charged to a card they forgot was on file.
The bundle also makes computers slower than they need to be, and the constant notifications train people to click "OK" on anything that looks like a security alert. That habit is exactly what scammers count on.
Verdict. Good engine, annoying product, expensive after year one. If you already have it and it is paid up, fine. I would not buy it new.
McAfee Total Protection
What it does well. McAfee's detection is respectable. It is not the top of the lab charts, but it is not embarrassing either. The company has been around forever and the product covers the basics.
What drives me nuts. McAfee mostly reaches people as a preinstalled trial on a new laptop. It nags from day one: "Your protection has expired." "Your PC is at risk." "Renew now." Those alerts look so much like a scam that actual scammers copy them. The fake "McAfee subscription expired" pop-up is one of the most common scareware pages I see, and the real McAfee has spent years training people to expect exactly that message.
McAfee has also historically been heavier on system resources than it should be, and uninstalling it cleanly sometimes requires their separate removal tool.
Verdict. If your new computer came with it, uninstall the trial and let Windows Defender take over. You will lose nothing meaningful. I would not pay for it.
Malwarebytes
What it does well. Malwarebytes started as a cleanup tool, and it is still the best cleanup tool for home users. If a computer is already infected with adware, browser hijackers, potentially unwanted programs, or scareware, Malwarebytes finds and removes that junk better than Norton, McAfee, or Windows Defender. It is the first thing I run on a machine that comes in with pop-ups, and I recommend the free version to everyone. It is in our free virus removal guide for that reason.
The paid Premium version adds real-time protection and web blocking. It is light, it does not nag, the interface is clean, and the company does not treat its customers like a renewal pipeline. Its behavior-based detection has also gotten genuinely good.
What it does not do. Malwarebytes has historically been less consistent than Bitdefender or Norton on the independent lab tests that measure blocking brand-new threats. It is a great second opinion and a great cleaner. As the only line of defense it is decent, not bulletproof.
Verdict. The best of the three, by far. If you are going to buy one consumer product, buy this one. Keep the free version around even if you do not.
And Windows Defender?
Honest answer: the built-in Windows Security is better than people think. It is free, it does not nag, and its lab scores are competitive with the paid consumer products. For a careful user, Defender plus a free Malwarebytes scan once in a while is a reasonable setup.
But Defender has the same fundamental problem as all of the above. Nobody is watching it.
The problem none of them solve
Here is what I see on infected machines that had antivirus installed:
- The antivirus did block something three weeks ago. The alert popped up, the person clicked OK, and nobody looked into how the malware got there in the first place. It came back.
- The antivirus was turned off by the scammer during the "support" call, and the person did not know.
- Windows had not installed updates in eight months because a reboot prompt kept getting dismissed. The attacker used a hole that was patched last winter.
- The hard drive had been throwing warnings for weeks. Then it died, and the antivirus had nothing to say about it because that is not its job.
- A remote-access tool was sitting in the system tray. The antivirus did not flag it because it is legitimate software. It was legitimately installed by a criminal.
Detection is only half the job. The other half is someone noticing, understanding what happened, and fixing the underlying problem. That is why businesses do not buy Norton. They buy something with a technician attached.
What the pros actually use: EDR with monitoring
On every business computer we manage, we run Bitdefender GravityZone with EDR alongside Syncro RMM. Here is what those two things mean in plain English.
Bitdefender GravityZone is Bitdefender's business product. Bitdefender's engine is consistently at or near the top of every independent lab test, year after year. GravityZone adds machine-learning detection, exploit blocking, and Ransomware Mitigation: when a process starts encrypting files, it is blocked and the files it touched are restored from copies Bitdefender made at that moment. That is not a backup and does not replace one, but it turns most ransomware hits into a non-event.
EDR stands for Endpoint Detection and Response. Instead of only asking "is this file on the bad list," it watches what programs do. When something behaves like an attack, it stops it and records the entire chain of events: what ran first, what it launched, what it touched. That record is what lets us clean a machine properly instead of guessing, and it is the reason a business can say "we know exactly what happened" after an incident.
Syncro RMM is remote monitoring and management. It watches the health of the computer and reports back to us: missed Windows updates, a hard drive starting to fail, a threat that was blocked, a machine that has not checked in. It also installs patches for Windows and common applications on a schedule so that "eight months without updates" cannot happen.
Put those together and you get something Norton cannot offer at any price: a person who finds out when something is wrong with your computer, and does something about it.
We now offer this to homes
For years this combination was only practical for businesses, because it is sold through IT providers rather than off a shelf. We are changing that.
Our Home Protection Plan puts the same Bitdefender GravityZone EDR and Syncro RMM monitoring we use for business clients onto your home computers. It costs $12.50 per month per computer when you set up autopay. The regular price is $25, so autopay is a straight 50% off.
What you get for that:
- Enterprise-grade antivirus with EDR and ransomware mitigation
- Windows and application patching handled for you
- Drive and hardware health monitoring, so you hear about a failing disk before it fails
- Alerts that come to CT Tech Express around the clock, not only to you
- No upsell pop-ups, no nag screens, no renewal surprise
- Works on Windows and Mac
Is it more than a box of Norton on sale? Over a year, yes. It is also a completely different product. One is software. The other is software plus a technician who is paid to notice.
The honest recommendation
- Tight budget, careful user: Windows Defender, plus free Malwarebytes for an occasional scan. Turn on two-factor authentication everywhere. Install updates when asked.
- Willing to pay for one consumer product: Malwarebytes Premium. Skip Norton and McAfee.
- You want to actually stop worrying about it, you work from home, you have been hit before, or you have a family member who clicks things: the Home Protection Plan, $12.50 a month per computer.
- Already infected right now: none of the above yet. Get the machine properly cleaned first. Our 5-stage virus and hacker cleanout is $150 flat, and we can put the protection plan on afterward so it stays clean.
