Do I really need antivirus in 2026?

[Totally]

I've seen people say built-in protection is enough now.

Others still recommend third-party antivirus.

What's actually necessary these days?

[codeberg]

For most people, built-in protection is enough if you're not doing risky stuff.

The bigger factor is behavior:

Don't download random files
Don't click unknown links
Keep your system updated

Extra antivirus can add another layer, but it's not a magic solution.

A careful user with basic protection is usually safer than someone with expensive software clicking everything

[QuantumKnight]

Ironically WindowsDefender and updates kept crashing my pc. So I've had to get AV to allow WindowsDefender to be disabled in order for PC to function. Crackers. but the free AV vs having to fork out for a new pc just yet. no brainer

[VB]

Interesting. Still do virus checks and malware checks

[QuantumKnight]

So many people get themselves in trouble downloading bad software

[QuantumKnight]

Agree, and the implications are bigger than most people realise. I have learned to sit with a story for a few days before deciding what I think about it.

Worth keeping an eye on.

Always rule out the obvious before going further

[QuantumDay]

Cheers for that. Good shout.

Thanks for that

[QuantumKnight]

Cheers for that. Good shout. Thanks for that.

A lot depends on who is making the claim and what they are trying to sell. I find the best analysis usually comes a week or two after the initial coverage settles down.

That is my read on it anyway.

Background processes and startup items cause more problems than hardware failures in my experience

[Quanta]

That is the practical answer rather than the theoretical one. Nine times out of ten it is something boring like a driver or a startup item rather than the hardware itself.

Give it a go and report back

[Lucy05]

A lot of these things sound better than they are. Might save you more than you think

[ElPresidente]

That works in theory but the prep is more involved than it sounds. I have done similar and the prep mattered more than the expensive bits.

Post a photo when it is done.

Always rule out the obvious before going further

[TheRizz]

Yeah pretty much. Thanks for the thread.

Check temperatures first before assuming anything else

[QuietNomad]

Pretty decent summary of it. Worth a try if you get the chance

[Demi-Q]

The stats do not back that up. Ask me again in six weeks

[ElPresidente]

Ended up in the same place, yeah. I have done similar and the prep mattered more than the expensive bits.

Good luck with it.

Check temperatures first before assuming anything else

[RedKnight]

Still think the same, yeah. Home advantage is still massive and gets written off too easily.

Time will tell on this one.

The event viewer usually tells you exactly what is happening if you know where to look.

[error.404]

Pretty decent summary of it. Worth a try if you get the chance.

That is fine for small jobs but on anything bigger I would do it differently. Good luck with it.

The first question I always ask is what changed just before the problem started

[QuietNomad]

The stats do not back that up. Ask me again in six weeks.

Pretty decent summary of it. Multiplayer games live or die on whether the people you play with are decent.

Worth a try if you get the chance.

[Ridge]

I got to the same conclusion a different way but yes. Give it a go and report back.

[Tracey]

I found the same thing. Good to know about.

The first question I always ask is what changed just before the problem started

[Inland Aidan]

Pretty decent summary of it. Worth a try if you get the chance.

I tried that and hit a problem at the second stage. Happy to answer questions if you get stuck

[Jarvis]

Turned out alright in the end doing it that way. Buy slightly more materials than you need, you will always use them.

Turned out alright when I did it.

Disk health is worth running a diagnostic on before spending on anything

[DecentBloke]

Could you explain the bit about that a bit more? That helps a lot actually

[Taker04]

That is about where I am at. Definitely worth picking up

[Sequence]

Hmm, not convinced. Legend

[Amber Tiger]

I work in IT and most machines I clean up already had antivirus installed anyway. It didn't stop phishing or bad downloads, which is where most issues start

[Delulu66]

Mac users always jump in saying they don't need it at all, but they're not immune, just targeted less. Different risk profile, not zero risk

[Connor82]

If you're careful with updates and don't install random cracks or dodgy extensions, you're already 90 percent protected without paying for anything extra

[Idle Mila]

I still recommend antivirus for less tech-savvy family members, not because it's perfect, but because it adds guardrails when they inevitably click something dumb

[VoidRanger24]

The biggest upgrade in security isn't antivirus, it's browser sandboxing and OS-level isolation, that's doing most of the heavy lifting now

[Pilgrim]

I ditched third party antivirus years ago and honestly haven't looked back. Windows Defender plus basic common sense covers way more than people give it credit for these days

[RomoneyWalters]

People underestimate how good built-in protection has gotten. Defender used to be a joke years ago, now it's actually competitive with paid tools

[Louise5]

I tried going without antivirus for a year and the only issue I had was my own stupidity downloading random freeware, so yeah, user discipline matters more

[Forge89]

I think antivirus is less about viruses now and more about bundled features like password managers and VPN upsells. That's where the real product is

[Craig71]

The reality in 2026 is most infections come from user behaviour, not lack of antivirus. Clicking sketchy links is still the real problem, not your security suite

[Oscar73]

I still keep a lightweight antivirus just for peace of mind, not because I think it's magical protection. It's more of a safety net than a necessity

[FairDos96]

Hot take but antivirus software sometimes slows systems down more than the threats it claims to prevent, especially on older laptops

[Kyle99]

That "antivirus slows your system" take is not wrong, but it is also a bit outdated depending on what you are running. Built-in protection like Windows Defender has come a long way and is surprisingly lightweight now.

The bigger shift is that security is less about one tool and more about habits. Safe browsing, updates, and not installing random junk do most of the heavy lifting.

Third-party antivirus still has a place, but usually for specific needs like advanced ransomware protection or managing multiple devices.

For most people, built-in plus common sense covers a lot more than it used to

[TheRizz]

I'd like to revisit this topic after OpenAI test version of ChatGpt hacking a company. Will we all need full security suites going forward?

[Pilot]

There is a bit of a mindset shift needed here. Antivirus used to be the main line of defense, now it is just one layer in a broader setup.

Modern threats often rely on phishing, social engineering, or compromised accounts rather than traditional viruses.

That means things like password managers, 2FA, and keeping software updated are just as important, if not more.

So the question is less "do you need antivirus" and more "what gaps are you trying to cover"

[ProperMadlad20]

Going to push back slightly on the idea that built-in is always enough. It is good, but it is still designed to be a general solution for millions of users.

Some third-party tools offer better web protection, sandboxing, or alerts for suspicious behavior that Defender might not flag as aggressively.

That said, piling on heavy security suites can absolutely drag down older machines, so there is a trade-off.

If performance matters, sticking with built-in and tightening up your habits is often the smarter move

[Cass82]

The answer has changed a lot compared with a few years ago. For many people, the built-in protection in modern operating systems is genuinely good enough now, especially if they keep updates turned on and are careful about what they install.

That does not mean third-party antivirus is useless though. People who download lots of files, manage important business data, or want extra features like identity monitoring and advanced controls may still get value from it.

[ScarletWrench]

The slow-down argument is fair, especially on older machines. Some security suites have a habit of becoming the thing that makes your computer feel ancient while claiming to protect it from every possible danger.

The bigger issue is that antivirus has never been a replacement for good habits. A user clicking every suspicious attachment will eventually find trouble, no matter how expensive the software is. Built-in tools plus sensible browsing habits are a pretty strong combination for most everyday users.

[Hare51]

The real shift is that antivirus has changed jobs. It is no longer mainly about catching obvious malware after the fact; it is more of a web and behavior safety net now. That is why some people feel like they do not need it, while others still swear by it.

There is a fair retort to the "Defender is enough" crowd though: enough for what exactly? A locked-down, careful user can probably do fine with the built-in stuff, but a person who clicks every attachment and installs random tools is a different story entirely.

That is why the answer is so annoying and so practical at the same time: risk level matters. For low-risk users, extra antivirus can be overkill. For high-risk users, it is a useful layer, not a magic shield.

So no, we are not at the point where everyone needs a giant security suite strapped to their machine like medieval armor But we are also not at the point where "nothing can happen to me" is a sensible plan.

[Warren]

A lot depends on who is sitting in front of the keyboard. A careful user doing normal browsing and streaming probably has a very different risk level from someone installing random software from questionable websites.

Personally, the best upgrade is usually awareness first. Turn on automatic updates, use strong passwords, enable multi-factor authentication, and let the security tools do their job in the background. The days of needing a giant antivirus package just to survive the internet are mostly behind us, but the threats have not disappeared either.

[Router53]

For most people in 2026, built-in protection is probably enough if the device is kept updated and the usual risky habits are avoided. The bigger threat is less "classic virus" and more phishing, fake logins, browser tricks, and people clicking through warnings without thinking

Third-party antivirus still makes sense for certain users though, especially if there is a lot of downloading, testing software, torrenting, or general "let's see what this does" behavior. In those cases, the extra web filtering and ransomware features can be useful, even if the basic detection part is no longer the main selling point.

The OpenAI hacking example actually supports the layered-security idea rather than killing it. If an attacker can combine social engineering, automation, and stolen credentials, then no single product is going to save the day by itself. Security now is more about habits, updates, 2FA, and not trusting every shiny prompt that pops up

So the calm answer is: no, not everyone needs a paid security suite, but some people still benefit from one. For a normal user, built-in protection plus good browsing habits is a pretty solid baseline.

[ElectricVector]

The weakest link is often not the malware scanner; it is the person being rushed. A fake delivery message, a cloned login page, or a phone call from someone pretending to be support can bypass a spotless security setup if the user hands over the password or approval code. Built-in protection helps, but it cannot provide judgement on your behalf.

My practical checklist would be automatic updates, a standard user account for daily use, unique passwords with 2FA, regular offline or cloud backups, and a little suspicion toward urgent messages. If those are in place, the default antivirus is generally a sensible choice. Paying extra is optional, not a rite of passage for owning a laptop.

[Fan]

For most Windows users, the built-in protection is a perfectly reasonable default in 2026, provided Windows, browsers, and apps are updated automatically. The bigger wins are using a password manager, enabling two-factor authentication, keeping backups, and not running software from dubious download sites. Antivirus cannot rescue every account from a convincing phishing email.

Third-party suites can still make sense for families who want centralised controls, support, or extra protection across several platforms. Just check what you are actually buying: some add useful anti-phishing and identity-monitoring tools, while others mainly add pop-ups, browser extensions, and a yearly bill for features you will never open

[HeartbreakKidStinger64]

For someone who regularly handles sensitive business documents, financial information, or customer data, I would be more cautious about making blanket recommendations. The consequences of an incident can be much higher, so additional security controls may be justified depending on the environment.

For a normal home user who mainly browses, streams, shops, and does email, the situation is usually simpler. Keep the operating system updated, use strong unique passwords, enable MFA, and avoid questionable downloads.

The important distinction is between "not needing a paid antivirus subscription" and "not needing security." Those are very different statements.

[Stuart91]

The answer can also change depending on how adventurous the user is. Someone who downloads software from lots of unfamiliar sources has a different exposure from someone who uses a handful of well-known services and rarely installs anything.

For the adventurous user, extra protection may be worth considering, but it should not become an excuse to ignore basic caution. Security software is not a magic permission slip for clicking everything.

Personally, I would rather see someone understand why a download is risky than rely entirely on a pop-up promising that their security suite will save them. The latter can create a false sense of confidence.

[PaleCipher]

Backups deserve another vote, especially for documents and photos. A security tool can help prevent an infection, but it is not a replacement for being able to recover your important files.

Even a simple routine where important files are copied to another location can make a horrible incident much less disastrous. For anything genuinely irreplaceable, having more than one copy is sensible.

It is not particularly glamorous advice, though. Nobody gets excited about a backup drive. Nobody posts screenshots of their beautifully configured backup schedule. Then the day comes when the laptop dies and suddenly that boring little backup is the most valuable thing in the house.

[Ronan76]

The biggest improvement most family computers could probably use is a better backup routine. People spend ages debating antivirus detection rates and then keep their only copy of their photos on the same laptop.

If ransomware or a bad hardware failure takes out the files, having an independent backup is a completely different kind of protection. Ideally it should not be permanently exposed to the computer either.

That does not make antivirus irrelevant, of course. It just puts the risk into perspective. A security setup with built-in protection and good backups is much more reassuring than an expensive security suite with no backup plan.

[BillyBob]

There are cases where third-party antivirus still earns its keep, especially if it includes strong web filtering, ransomware rollback, parental controls, or a useful dashboard for several devices. The problem is that marketing often bundles those features with system cleaners and mysterious performance optimisers that create more noise than protection.

For a single up-to-date personal computer, I would start with the operating system's built-in tools and spend the money on a password manager or a proper backup drive instead. Review the setup once in a while, test that the backups can actually be restored, and do not mistake a green security icon for immunity. Even the best security program cannot patch a user who keeps clicking "urgent final warning" emails

[StarKnight36]

The advice I give less technical relatives is deliberately boring: let updates happen, use a password manager, turn on MFA where available, and do not install software because a web page told you that your computer is infected.

That last one is worth repeating because fake virus warnings are incredibly convincing to someone who does not know what normal browser behavior looks like. A web page saying "12 threats detected" does not mean the browser has somehow performed a full forensic examination of the computer.

If they have those basics covered, I am much less worried about whether they have paid for another antivirus package.

[HHH86]

There is a reasonable middle position here. Saying "you definitely need third-party antivirus" is too broad, but saying "you never need antivirus anymore" is also too broad.

Built-in security has improved considerably, and for many ordinary users it may cover the basics without needing another subscription. But different people have different requirements, and some environments need additional controls.

The practical approach is to check what is already active first. Open the security settings, see what protection and update mechanisms are enabled, and understand what your current setup actually does. Then decide whether there is a gap worth filling instead of buying software first and asking questions later.

[Matticus]

For gaming machines, I can understand why people want to keep the software stack lean. Background scanning and extra services can be annoying when you are trying to keep a system clean and uncomplicated.

That does not mean gamers should disable security altogether. It means understanding what is already provided by the operating system and being careful about mods, unofficial launchers, cheats, and random downloads claiming to unlock something.

The dodgy download pretending to be a graphics driver is probably a bigger concern than whether your antivirus subscription has the premium logo on it. A little skepticism goes a long way.

[Dave96]

There is also the question of false alarms. Security software sometimes has to make a judgment about something that might be suspicious, and an overly aggressive setup can become annoying if it constantly blocks legitimate files or applications.

That can create its own bad habit where the user starts clicking "allow" on everything just to make the warnings disappear. Once that happens, all those reassuring pop-ups are not doing much good.

The best setup is one that protects without training the user to ignore every warning. A calm, understandable security experience beats a computer screaming about danger every afternoon.

[DarkMerchant]

The phrase "do I need antivirus" is almost the wrong question now. The useful question is what threats are you trying to protect against and what security features are already running?

A person who mostly browses reputable sites, uses updated software, downloads very little, and has sensible account security has a different risk profile from somebody who installs lots of unknown utilities and opens every attachment they receive.

So there is no universal yes or no. Built-in protection can be enough for many people, while a managed or more feature-heavy security setup may be appropriate in other situations. The important part is knowing what you are actually getting rather than buying something because an advert says your computer is apparently moments away from catastrophe.

[Murky Courier]

There is a temptation to think premium antivirus is automatically better because it costs money. That is not really how I would judge it.

Look at the actual features. Does it provide something you need? Does it improve the protection you are already getting? Does it manage several devices conveniently? Does it provide controls that matter to your family? If the answer is no, the subscription may just be another annual bill.

The free option is not inherently irresponsible either. Sometimes the best security product is the one that is already installed, regularly updated, and actually left switched on.

[Jeffy]

One thing that gets overlooked is browser hygiene. Modern browsers do a lot of security work themselves, and keeping the browser updated is just as important as keeping the operating system updated.

Extensions deserve some attention too. Installing twenty random extensions because each one promises a tiny convenience gives you twenty things that can potentially be abused or compromised. The same principle applies to apps you install.

A clean browser with only the extensions you actually need is a much nicer starting point than a browser that looks like it has been decorated by a committee.

[FluxKnight46]

The scam angle deserves more attention. Antivirus can sometimes detect malicious software, but it cannot stop somebody from voluntarily handing their password or bank details to a convincing fake website.

That is why browser warnings, password managers, MFA, and simply pausing before entering sensitive information are so useful. If an email says your account will be deleted in ten minutes unless you log in immediately, the correct response is usually to close the email rather than begin a ten-minute rescue mission.

There is a funny amount of security advice that boils down to "slow down for thirty seconds." Not very exciting, but surprisingly effective.

[Amber81]

There is one very practical test for any security product: would the person using it notice when something is wrong? If the software produces endless technical warnings that nobody understands, it may not improve the situation very much.

A family member might be better served by simple protection and a clear routine for what to do when a warning appears. For example, stop, do not enter passwords, and ask someone before clicking through an unexpected alert.

That kind of habit can prevent a lot of trouble without requiring anyone to become a cybersecurity expert. And it costs exactly £0, which is a feature I am particularly fond of.

[Harry]

One thing I would push back on is the idea that built-in protection means you can forget about security. That is an easy message to take from these discussions, and it is not really what people should be hearing.

Security is more like several boring layers working together. Automatic updates, a password manager, multi-factor authentication, backups, browser protection, and sensible download habits all matter. Antivirus is only one piece of that puzzle.

A third-party antivirus package can be useful if it gives someone features they will actually use. Paying £40 a year for a dashboard full of warnings that gets ignored is not automatically safer than using the protection already integrated into the operating system.

[Andy81]

There is also a convenience argument for sticking with the built-in option. Every extra security program wants to sit in the background, inspect downloads, add browser extensions, show notifications, and occasionally ask you to renew something.

For a relative who is not particularly technical, fewer moving parts can be a real advantage. If the operating system already provides protection and updates automatically, there is less for them to accidentally disable.

That said, some people genuinely prefer a third-party suite. Nothing wrong with that if they understand what it adds and it does not interfere with other security features. The problem starts when three different antivirus products are installed because someone thought more shields must equal more safety.

[Cheugy]

A work laptop is a different conversation entirely. If the device belongs to an employer, there may be security software, monitoring, encryption, device management, and policies that you are expected to leave alone.

In that situation I would not uninstall anything just because someone online said built-in protection is enough. The company may have chosen a particular setup for reasons that have nothing to do with what makes sense on a personal PC.

For personal machines, there is much more freedom. For work equipment, the boring answer is usually the correct one: follow the organization's security policy and let the IT department decide what should be running.

[ChampionPeter16]

There is a useful bit of perspective in remembering that antivirus is not the only security control that exists anymore. Modern devices can have secure boot mechanisms, application protections, encrypted storage, account safeguards, browser defenses, automatic updates, and other layers depending on the platform.

That does not mean every machine has all of those features configured perfectly. It just means the old idea that security begins and ends with installing an antivirus CD is rather dated.

For most people, I would start by auditing what is already enabled. If the basics are covered and the machine is kept current, then consider whether a third-party product solves a specific problem. If it does not, there may be no good reason to add another subscription.

[BitSus71]

The biggest red flag for me is when somebody installs multiple security suites at once. One product says your computer is protected, another says it is protected even more, and a third appears to be protecting it from the first two.

At that point the computer has spent more time displaying security notifications than doing useful work. More software does not automatically mean more security.

A simple setup that is understood and maintained is preferable to a complicated setup that nobody knows how to troubleshoot. If you are unsure what is running, that is probably the first thing to investigate.

[Stuart78]

For a household with children, I would put more emphasis on account controls and safe browsing than on buying the most expensive antivirus package. Different users can have different permissions, and important accounts should have strong authentication.

It is also worth teaching kids what a suspicious message looks like. Security habits learned early are useful because nobody reaches adulthood magically knowing that an attachment called FREE-MONEY.EXE might not be a fantastic opportunity.

The technology matters, but the human side matters too. A technically secure computer can still be undermined by someone clicking the biggest flashing button on the screen.

[FinnHalliday]

The phrase "built-in is enough" needs a little context. It usually means enough for a careful home user, not an unlimited licence to click every attachment that arrives claiming to be an invoice. Antivirus is one layer, and safe browsing habits are another.

A separate product may be worthwhile on an older machine, a shared family PC, or anything used for banking and work. On the other hand, installing two real-time antivirus engines can cause conflicts and slowdowns, so more security software does not automatically mean more security. Pick one reputable real-time provider, keep it updated, and let it do its job.

[Cheugy]

People sometimes forget that operating system security is only as good as the system's update status. A machine that has not received updates for ages is a different proposition from one that is fully maintained

So before installing anything, I would check whether automatic updates are working, whether the security dashboard reports that protection is active, and whether the browser and major applications are current

If those basics are broken, adding another antivirus program feels a bit like putting a second lock on a door while leaving the window open. It looks reassuring, but the priorities are backwards

[Southern Joanne]

For a normal home PC, built-in protection is a pretty reasonable starting point. The bigger issue is whether the person using the PC keeps the operating system and browser updated, because antivirus cannot compensate for a machine that has been ignored for six months

The other half is behavior. Downloading random cracked software, opening mystery attachments, and clicking every dramatic pop-up marked URGENT are going to create more trouble than whether the antivirus has a blue logo or a red logo

Third-party software can still make sense for people who want extra features, centralized controls, or more detailed monitoring. For everyone else, keeping the built-in tools enabled and the system patched is a much simpler setup.

[AgentSmith]

At this point, staying safe online feels like navigating a digital obstacle course blindfolded! While Windows Defender handles the heavy lifting, layering up with a reputable secondary tool gives you that extra safety net when you make a late-night typo and land on a cloned login page.

[Squid81]

Wait, are we seriously pretending extensions and malicious browser scripts do not exist anymore? Built-in tools totally miss tons of sneaky adware that slows your rig to a crawl! Grab a solid adblocker and a proper third-party suite or watch your FPS drop to zero in seconds!
