The best antivirus software for many older adults is the protection already built into their computer and phone, kept up to date. A paid product can add useful extras, but it isn't the first line of defense against the tricks aimed at people over 60. This guide compares the main options in plain English and gives you the questions to ask before you pay. Take your time.
Most trouble on a computer today starts with a scam, not a virus. Our main guide to senior scams explains those tricks. This page covers the software side.
A note on products: nothing here went through our own hands-on trials. Every option carries the Researched label: the details come from the makers' public descriptions and official guidance, so check them on the maker's site before you buy. No rankings, no prices.
Do you still need antivirus in 2026?
You need protection. The question is whether you need to buy it.
Windows computers come with Microsoft Defender Antivirus, part of the Windows Security app, and it runs on its own unless another antivirus replaces it. Macs include built-in malware protection from Apple that works in the background. Android phones come with Google Play Protect, which checks apps for harmful behavior. On an iPhone, most protection comes from Apple's software updates and the App Store rules.
CISA, the federal agency for cybersecurity, sums up everyday safety in four habits on its Secure Our World page: use strong passwords with a password manager, turn on multifactor authentication, recognize and report phishing, and update your software. Notice that buying antivirus isn't on the list. Updates are.
If your computer still runs Windows 10
Microsoft stopped free security updates for Windows 10 in October 2025. The system no longer gets its regular free fixes, and antivirus can't replace them. Microsoft offers Extended Security Updates for a limited time, paid or under certain conditions, and some computers can move to Windows 11. To see your version, click Start and type "About your PC." Microsoft's page on Windows 10 end of support explains the options.
So here's the honest answer. For many people, the best antivirus software is the built-in kind plus automatic updates. A paid product makes sense when you want extras, when you'd like one company to handle several devices, or when a family member who helps you prefers one they know.
Best antivirus software options compared
Here are the five types you'll run into, from free to full-featured.
Built-in protection (free)
What it is: Microsoft Defender on Windows, Apple's protections on Mac and iPhone, Google Play Protect on Android.
Good for: most people who keep their devices updated and don't want another subscription.
Limits: fewer extras, and the settings can be hard to find.
Basic paid antivirus
What it is: a stand-alone program that scans for harmful files and blocks dangerous downloads, usually for one computer or a small number of devices.
Good for: people who want a single, clear dashboard or a company they can phone for help.
Limits: it often overlaps with what your computer already does.
Full security suite
What it is: antivirus plus extras. Depending on the plan, that may include web protection, a VPN (a tool that scrambles your internet traffic so others on public Wi-Fi can't read it), a password manager, parental controls or identity monitoring. Norton, McAfee and Bitdefender are well-known names in this group.
Good for: households with several devices, or people who travel and use hotel or coffee shop Wi-Fi.
Limits: more screens, more alerts and more to learn. Some extras duplicate free tools you already have. If you want to see what a suite includes, you can compare current security suite plans on the maker's site.
Browser scam and phishing protection
What it is: warnings built into your web browser. Chrome uses Google Safe Browsing and Edge uses Microsoft Defender SmartScreen to flag known dangerous sites before they open.
Good for: everyone. It's free.
Limits: it only knows about sites that have been reported. A brand-new fake page can slip through.
Phone security apps
What it is: apps from security companies for iPhone or Android, often part of a suite.
Good for: Android users who install apps from outside the Play Store, or people who want scam-text filtering in one place.
Limits: on an iPhone these apps can't scan the phone the way computer antivirus does.
Norton vs McAfee, and other big names
"Norton vs McAfee" is one of the most searched questions about the best antivirus software, and I understand why. They're the names many of us remember from the first family computer.
Both are long-standing paid suites with extras beyond virus scanning. We haven't run our own trials, so we won't say one beats the other. Here's how to compare any two brands fairly:
- Devices covered. Check that the plan covers all your computers, phones and tablets.
- Screens you can read. Does the app respect your larger text setting? Are buttons labeled with words?
- Renewal price. The first-year price is often lower than what you pay after. Read the renewal terms.
- Cancelling. Find out how to turn off automatic renewal before you sign up.
- Real help. Is there a phone number or chat listed on the maker's official site?
Scams that pretend to be antivirus
Even the best antivirus software can't hang up the phone for you.
Most Saturday mornings, someone sets a laptop on the library table in front of me and says it has a virus. Usually it doesn't. What they saw was a scary pop-up, sometimes with a loud alarm, saying the computer is infected and giving a number to call. The person who answers wants to take control of the computer, and then wants to be paid.
The FTC says real tech companies don't put phone numbers in security warnings. If you see one, don't call. Close the browser. If it won't close, hold down the power button until the computer turns off, then turn it back on.
A second trick arrives by email: a "receipt" saying your antivirus subscription renewed for a large charge, with a number to call if you want a refund. The call leads to a fake refund and a request to log in to your bank. Check your real card statement instead.
Scam alert
No real security company will call you to say your computer is infected. When in doubt, hang up and call back using the number on the company's official website, not the one in the message.
Facebook and Messenger links: where software helps and where it can't
Many scams that reach older adults travel through Facebook and Messenger. A friend's hacked account sends "Is this you in this video?" with a link. A giveaway page asks you to sign in to claim a prize. The link opens a fake login page that steals your password.
Browser protection and a security suite's web filter can block known bad pages. They can't block every new one, and they can't stop you from typing your password into a page that looks real. These habits cover the gap.
- Don't sign in from a link. Open the Facebook app or type the address yourself.
- Check with the friend another way. Call or text them before you click anything they "sent."
- Turn on two-step verification. Meta's Help Center explains where to find it in Settings.
If someone does get your password, a password manager and two-step verification limit the damage. Our guide to the best password manager for seniors compares the main types.
Questions to ask before you pay
Before you buy any of the best antivirus software options, sit down with these questions and a pen:
- Is my built-in protection turned on? On Windows, open Windows Security and look for green check marks.
- Are my updates automatic? On a phone, look in Settings under Software Update or System.
- What would a paid product give me that I don't have?
- How many devices do I need to cover?
- What is the price after the first year, and how do I cancel?
- Who helps me if I get stuck? A family member, a local shop or the company's own support.
If you get stuck
Can't find the security settings? That is normal. Search your device's settings for "security" and open the first result, or ask a relative to check it with you.
If your worry is less about viruses and more about who has your personal details, a data removal service and identity theft protection address different parts of that problem.
Frequently Asked Questions
Do I still need antivirus in 2026?
You need protection, but you may already have it. Windows 11 comes with Microsoft Defender, Macs have Apple's built-in malware protection, and Android phones have Google Play Protect. Kept updated, they cover the basics. Windows 10 no longer gets free security updates, so check your options if you still use it. No product can stop a scam where you are talked into paying.
Is Norton or McAfee better?
Both are long-standing paid security suites with antivirus, web protection and extras such as a VPN or identity monitoring, depending on the plan. We haven't run hands-on trials, so we won't crown either one. Compare them on the points that matter to you: which devices are covered, how clear the screens are, the renewal price and how to cancel.
What is better than Norton?
No single product is better for everyone. For many people, the built-in protection on a Windows PC or Mac, kept up to date, is enough for everyday use. Others prefer a different paid suite because it covers more devices, has simpler screens or includes a feature they want. Judge any option on coverage, clarity, support and renewal terms.
Do iPhones and Android phones need antivirus?
Phones work differently from computers. On an iPhone, most protection comes from Apple's updates and the App Store rules, and security apps can't scan the phone the way computer antivirus does. Android phones include Google Play Protect. On both, the real risk is usually a scam text or a fake link, so updates and a careful habit matter most.
One thing to try this week
Open the security screen on your main computer. On Windows, click the Start button and type "Windows Security." On a Mac, open System Settings, then General, then Software Update. Make sure protection is on and updates are automatic. For the full picture of the tricks to watch for, read our guide to senior scams.
