The Antivirus Industry in 2026: A Buyer’s Guide for People Who Actually Read Reports

The market nobody trusts and everybody pays for

By Geist | August 19, 2026

The antivirus market in 2026 is the same shape it has been since the early 2000s. A handful of vendor names show up in every retail box and every preinstall. The names get louder. The detection engine inside them quietly rotates. The labs that grade the engines get paid by the engines. The marketing then quotes the labs. The cycle is the product.

What is different now is the threat surface. The labs are still measuring whether a suite can stop a known sample dropped onto a Windows desktop. The actual attackers in 2026 are not doing that. They are phishing credentials, abusing identity providers, hiding in Microsoft cloud tenants, signing malicious drivers, and turning the endpoint protection itself into the initial access payload. The thing on your desktop that says “protected” is doing a job that is one or two layers removed from the actual fight.

That gap is the reason this post exists. A pure detection rate leaderboard is not a buyer’s guide. A buyer’s guide has to weigh what the product stops, what it misses, what it costs in performance, what it bundles that you do not need, what it costs you in renewal pricing, and how the company behaves when something goes wrong. The post works through the seven names that actually matter for a 2026 buyer, runs them through the public lab data and the public failure data, and ends with a defensible recommendation.

One editorial bias to declare up front. The author has run Trend Micro on personal machines and on customer sites for close to a decade. The 2026 detection numbers do not always have Trend Micro on top, and the post says so. The recommendation at the end is for the product that does the most useful work for the most readers, and the case for that product is built on the data, not the preference.

Sources for the table: AV-TEST, March/April 2026 Windows 11 round; AV-Comparatives Real-World Protection Test, Feb-May 2026; AV-Comparatives Performance Test, April 2026; MITRE press release on 2025 Enterprise Evaluation, 10 Dec 2025; vendor disclosures and newsrooms as cited in the body sections below.

What the lab data does and does not tell you

Before working through the products, a note on the data. AV-TEST runs the same suite on a stock Windows 11 image and feeds it samples the lab has collected. AV-Comparatives does the same with a slightly different methodology. SE Labs runs an independent test based on public threat feeds. The three disagree on a few percent of cases, and the disagreement is the most useful data. If a product scores 100% in one and 97% in another, the gap usually comes from what each lab counts as a “user dependent” outcome, meaning the user saw a warning and chose to proceed.

What the labs do not measure well is the layered attack. A sample dropped on a desktop is one thing. A real 2026 intrusion is more like a credential phish, a session token theft, an identity provider API call, a Microsoft Graph upload, and a series of legitimate-looking admin actions. The endpoint product that catches the dropped sample might miss the Graph upload, and the labs do not have a test that captures both halves of that chain in a single score.

MITRE ATT&CK Enterprise Evaluations get closer. The 2025 round tested a financially motivated intrusion and a China-aligned espionage scenario across endpoint, identity, and cloud. CrowdStrike published a 100% detection and 100% protection result. Sophos published 100% detection at 86 of 90 technique-level detections. The participants in 2025 were Acronis, AhnLab, CrowdStrike, Cyberani, Cybereason, Cynet, ESET, Sophos, Trend Micro, WatchGuard, and WithSecure. Microsoft, SentinelOne, and Palo Alto Networks withdrew. Three of the seven names in this post did not enter, so their MITRE numbers are either from a prior year or are not public. That matters for the comparison.

Norton 360 and the Gen Digital empire

Norton is the consumer face of Gen Digital, the company that merged Norton, LifeLock, Avast, AVG, and a handful of smaller brands. The product line bundles antivirus, a no-limits VPN, a password manager, dark web monitoring, and identity theft insurance on the higher tiers. The marketing is aggressive. The detection is competitive.

In the AV-Comparatives February-May 2026 protection test, Norton blocked 397 of 400 live samples for a 99.3% protection rate, tied with Avast and AVG (which makes sense, since Gen shares engines across the three brands). That is Cluster 1 in the lab’s own ranking. AV-TEST gave Norton 360 a 6.0 in protection, performance, and usability in the April 2026 round and awarded Top Product. The product is doing the job the labs measure.

The reason Norton is not the recommendation for the readers this post is written for is the identity layer. NortonLifeLock disclosed in late 2023 that credential stuffing had compromised approximately 925,000 customer accounts. The intrusion used credentials harvested from other breaches and worked because Gen had not enforced the kind of rate limiting and breached-password checking that would have caught the attack. The notification went out, the customers rotated passwords, and the company added the controls. That is a competent response to a credential stuffing incident and not a sign of a broken product.

What it is a sign of is that buying Norton for the identity protection is buying into a category of product that has its own attack surface. The endpoint engine is good. The identity monitoring service is reasonable. The combination is convenient. If the combination ever breaks, the blast radius is your identity service and your endpoint at the same time. The Telekom Deutschland breach of late 2024 and the Snowflake campaign of mid 2024 also drove up breach notification volume to Norton and LifeLock users, with breach notifications to Norton and LifeLock users rising 628.1% from H2 2025 to H1 2026 per Gen’s own threat report. The product is doing its job, but its job is now twice the size it was five years ago.

McAfee and the lightness story

McAfee is the surprise of the 2026 numbers, for two reasons. First, the engine kept up with the cluster 1 products in the AV-TEST rounds: 6.0 / 6.0 / 6.0 and Top Product in April 2026. Second, the April 2026 AV-Comparatives Performance Test ranked McAfee as the lightest paid consumer suite, with a 3.3 impact score and a 96.7 Procyon score, ahead of Kaspersky, ESET, and Trend Micro. That is a notable reversal for a product that has historically been on the heavier end of the consumer spectrum.

The McAfee+ product line is the part that is worth understanding. The base tier is antivirus, an unlimited VPN, a firewall, and an AI-powered Scam Detector that watches SMS, email, links, and QR codes. The higher tiers add dark web monitoring, $1 million to $2 million in identity theft insurance, three-bureau credit monitoring, and personal data cleanup against data broker sites. The bundle is unusual because the identity side is built into every tier, including the entry-level plan. Most competitors lock the identity stuff behind a separate subscription.

The performance numbers are the reason to take McAfee seriously. The detection is mid-pack, the system impact is best-in-class, and the Scam Detector is the kind of thing a parent or grandparent will use. The weaknesses are the ones that come with the McAfee brand: aggressive upgrade prompts on the paid plans, and a full removal that historically required the dedicated McAfee Consumer Product Removal tool. The product is a better choice for non-technical household users who want one subscription covering everything than for a security professional who wants precise control.

Trend Micro, the product the post is built around

The honest read on Trend Micro in 2026 is this. The detection is not on the very top step. The 98.3% real world protection rate in the Feb-May 2026 AV-Comparatives round is Cluster 2, 7 of 400 missed, alongside McAfee, Total Defense, ESET, and K7. The 99.97% Kaspersky, 99.5% Bitdefender, and 99.3% Norton and Avast family all sit above it. Anyone who tells you Trend Micro is the best at stopping a file dropped on a Windows desktop is not reading the public lab data.

What Trend Micro does do well is more useful than the top of the leaderboard for the readers this post is written for.

System impact is consistently in the top half of paid consumer suites. The April 2026 AV-Comparatives Performance Test ranked Trend Micro 4th lightest of the paid consumer suites tested, with a 4.7 impact score and 95.3 Procyon score. McAfee (3.3), Kaspersky (3.5), and ESET (4.2) are ahead on impact. Norton (5.3) and Avast/AVG (5.5) are behind. Bitdefender (9.6) and Microsoft Defender (12.9) are noticeably heavier. That ordering is the one the post recommends you memorize if you actually care about what running an antivirus does to your laptop’s battery and your application’s launch time.

Folder Shield extends ransomware protection to cloud sync folders. Most ransomware modules protect the local Documents and Pictures folders and stop there. Trend Micro Folder Shield also watches OneDrive, Dropbox, Google Drive, and the cloud sync folders that have replaced the local Pictures folder for most users. The reason this matters is that the average ransomware family in 2026 first encrypts the cloud sync client, which then pushes the encrypted copies to the cloud and the local cache at the same time. A product that only protects local folders is protecting the wrong half of the user’s files. Trend Micro is one of the few consumer suites that has caught up to this attack shape.

Pay Guard is a hardened browser for banking and shopping. When the engine detects that the user is on a known financial site, it launches a separate, hardened browser session that isolates the financial transaction from the rest of the browser’s process tree. The implementation is a closed-fork of a major browser with most plugins and extensions disabled. The security benefit is that any malicious extension or injected script that has compromised the user’s normal browser cannot reach the banking session. The tradeoff is that the user has to be on the supported list of financial sites, and the feature costs a few percent of CPU during the session. For users who do online banking, this is one of the most useful single features in any consumer suite.

The Smart Protection Network has 15+ years of file and URL reputation data. Trend Micro’s cloud reputation system has been running since 2008, and the data set is large enough to give the local engine a reputation answer on most files before the local scan even starts. The practical effect is that the first scan of a new machine is much faster than it would be otherwise, and unknown executables get a reputation verdict in milliseconds rather than minutes. The 2026 number for this is in the low billions of queries per day across the network, and the local engine treats that as a first line of defense rather than a fallback.

The XGen engine is genuinely layered. The marketing copy talks about “cross-generational threat defense,” which is the kind of phrase that should make any reader suspicious. The actual layering is more interesting. The engine applies high-fidelity machine learning both pre-execution and at runtime, runs behavioral monitoring on the running process, applies variant protection to catch polymorphic repackagings of the same family, and uses census and whitelist checks to keep false positives down between layers. Most of the competitors do something similar. Trend Micro has been doing it longer than most, and the layering is more visible in their public product documentation than in the average competitor’s whitepaper.

TrendAI Vision One is the most credible enterprise XDR from a vendor that also has a consumer product. The 2026 Gartner Magic Quadrant for Endpoint Protection Platforms named Trend Micro a Leader. The same press release notes that Trend Micro scored the highest in two of three use cases in the companion Critical Capabilities document (Workspace Security and On-premises Endpoint Protection Management) and second highest in the third (Core Endpoint Protection). For a buyer who needs an enterprise XDR that came out of the same engineering organization as the consumer product, Vision One is the cleanest answer in the market. The MITRE ATT&CK 2025 Enterprise round included Trend Micro as a participant, which Microsoft, SentinelOne, and Palo Alto did not.

The free HouseCall scanner is genuinely useful. Trend Micro has kept HouseCall as a free, browser-launched second-opinion scanner for over two decades. A second-opinion scanner from an independent engine is one of the cheapest security improvements a Windows user can make, and Trend Micro gives it away. The on-demand engine is not the same as the on-access engine in the paid product, but it is the same vendor’s view of the threat landscape, and running it on a machine that already has a different endpoint product is a useful sanity check.

The weaknesses of the Trend Micro product in 2026 are real. The detection numbers are cluster 2, not cluster 1. The bundling on the consumer side is less ambitious than Norton’s or McAfee’s. The Vision One enterprise platform is broad enough to be complex, and the small business tiers between Maximum Security and Vision One are thinner than they should be. None of these are dealbreakers, and the strengths above outweigh them for the kind of user this post is written for. The recommendation at the end of the post is for Trend Micro Maximum Security on a single device and Trend Micro Internet Security on a household, with the caveat that any user who lives inside the Norton or McAfee identity bundle for financial reasons should stay where they are.

Kaspersky, the best engine you are not supposed to run

Kaspersky’s detection engine in 2026 is the best in the public lab data, period. The Feb-May 2026 AV-Comparatives round had Kaspersky blocking 399 of 400 live samples for a 99.8% protection rate, the highest of any vendor tested. AV-TEST rounds have consistently given Kaspersky 18 of 18 across the same period. The engine is what the engine is.

What the engine is, in 2026, is also a regulatory and supply-chain problem. The US Department of Commerce issued a Final Determination in June 2024 under its ICTS authorities prohibiting Kaspersky from directly or indirectly providing covered cybersecurity products and services in the United States or to US persons. The prohibition took effect in stages: no new agreements after 20 July 2024, no updates to existing US customers after 29 September 2024. The Office of Foreign Assets Control separately designated 12 Kaspersky executives on the SDN list on 21 June 2024. The German BSI has maintained its March 2022 warning through 2025, and Australian government agencies were directed to remove Kaspersky from all systems by April 2025.

The basis for the US action, as stated in the Final Determination, is not that Kaspersky has been caught shipping malicious code. It is that Russian law can compel a Russian-domiciled company to cooperate with Russian intelligence and law enforcement services, that antivirus software has deep system privileges, and that the combination creates a risk to US national security. The BIS determination is explicit that the risk is in the legal exposure, not in the current code. Kaspersky has consistently denied the allegations and has pointed to its data relocation to Switzerland, its Global Transparency Initiative, and its SOC 2 audits as evidence of independence.

For a US reader, the practical consequence is that running a current copy of Kaspersky on a personal machine in 2026 means running an out-of-date product with no signature updates, no KSN access, and no support. The engine may be the best in the world, but the version you can legally install is the version from before September 2024. For a reader outside the US, the engine is excellent, the legal exposure depends on jurisdiction, and the German BSI is the most rigorous official warning still in force.

The post does not recommend Kaspersky. The post notes the engine quality because the engine is the comparison everyone in this category is making, and the post would be incomplete without saying so. The recommendation is for a product you can actually update in 2026.

Bitdefender and the protection purist bet

Bitdefender has been at or near the top of the public lab data for more than a decade. The Feb-May 2026 AV-Comparatives round had Bitdefender at 99.5%, second only to Kaspersky. The March 2026 AV-Comparatives Malware Protection Test had Bitdefender at 97.6% offline, 97.6% online, and a 99.94% online protection rate with 4 false alarms, the lowest false alarm count of any mainstream suite in that round. AV-TEST’s April 2026 round gave Bitdefender Total Security a clean 18 of 18 and Top Product.

What Bitdefender is best at is the protection engine and the false positive rate. A low false positive count is more important than a 0.2% detection difference in the lab data, because a false positive on a real business tool costs the user more in lost work than a missed sample costs in cleanup. Bitdefender’s false alarm count in the March 2026 round was 4 against an industry average around 9. The MITRE ATT&CK 2024 round had Bitdefender at 91% analytic detection with the best alert-to-noise ratio of any entrant. The 2025 round participation has not been confirmed in the December 2025 MITRE press release list.

What Bitdefender is worst at is system impact. The April 2026 AV-Comparatives Performance Test ranked Bitdefender 9th of the paid consumer suites tested, with a 9.6 impact score and 95.4 Procyon score. That is the heaviest of the leading protection engines. On modern hardware, the difference is mostly invisible. On older hardware, on a battery-constrained laptop, on a development machine compiling large projects, the difference is noticeable. The mobile product is the bright spot: AV-Comparatives’ June 2026 mobile round had Bitdefender at 100% detection with 2 false positives and 0.5% battery impact, the best of the commercial mobile products tested.

The post’s recommendation for a protection purist who does not need an identity bundle is Bitdefender Total Security on a modern machine. For an older machine or a heavy compute workload, the recommendation changes.

ESET, the European lightweight

ESET is the third engine with a long track record of high detection and low system impact, headquartered in Slovakia and a perennial favorite of the European SMB market. The Mar 2026 AV-Comparatives Advanced Threat Protection test awarded ESET Gold. The Apr 2026 AV-Comparatives Performance Test ranked ESET 3rd lightest paid consumer suite at 4.2 impact. The AV-Comparatives February-May 2026 test had ESET at 98.5%, Cluster 2, 6 of 400 missed. AV-TEST’s Mar 2026 round for Smart Security Premium was 6.0 in protection, 5.5 in performance, 6.0 in usability. ESET has won more VB100 awards in the history of Virus Bulletin than any other vendor.

The interesting feature on the consumer side is the UEFI scanner, which runs before the operating system loads and can detect bootkits and firmware-level malware that the operating system cannot see. That is a rare capability in a consumer product, and it is the reason some security researchers run ESET on personal machines even when the lab numbers do not put it on the top step.

The product is more configurable than most consumer suites, which is good for security professionals and bad for the non-technical household user who wants a product that does not need configuring. ESET did not include an identity bundle comparable to Norton or McAfee at the time of this post. The product for the post’s target reader is NOD32 Antivirus or HOME Security Essential, not the upper-tier Premium or Ultimate.

Microsoft Defender, the suite you already paid for

Microsoft Defender is the only product in the post you did not have to buy. It ships with Windows 10 and Windows 11, it is on by default, and it has gotten steadily better over the last five years. The AV-Comparatives February-May 2026 test had Defender at 99.0% protection, Cluster 1, 4 of 400 missed. AV-TEST’s June 2026 round gave Defender a clean 18 of 18. The product is competitive with the leading paid suites on the lab numbers.

What Defender is bad at is the things the labs do not measure. The configuration surface is buried in Windows Security, Group Policy, and Intune. The SmartScreen filter for browsers and the Smart App Control for executable blocking live in different settings panes from the on-access engine. The Controlled Folder Access ransomware protection is off by default on most consumer SKUs. The Cloud Protection network telemetry opt-in is on by default, which means Defender is sending a lot of behavioral data to Microsoft, which is a separate question from whether the engine works.

What Defender does not have is an identity bundle, a third party hardened browser for banking, or an enterprise XDR you can buy from the same vendor without committing to the Microsoft 365 stack. The product is a good default. The post’s recommendation for a non-technical user who is not paying attention to security is to leave Defender on, enable Controlled Folder Access, and stop paying for a consumer AV suite that does the same job.

MITRE ATT&CK mapping, who tested what in 2025

The 2025 MITRE ATT&CK Enterprise Evaluation ran two scenarios, a financially motivated intrusion against a hybrid environment and a China-aligned cyber espionage campaign. The participants, per the December 2025 MITRE press release, were Acronis, AhnLab, CrowdStrike, Cyberani, Cybereason, Cynet, ESET, Sophos, Trend Micro, WatchGuard, and WithSecure. Microsoft, SentinelOne, and Palo Alto Networks withdrew before the round. CrowdStrike published a 100% detection and 100% protection result with zero false positives. Sophos published 100% detection at 86 of 90 technique-level detections.

The mapping for the consumer products in this post is approximate, because consumer and enterprise products are not the same binaries and not the same configurations. The trends are still useful.

• CrowdStrike Falcon: 100% detection, 100% protection, zero false positives in 2025 Enterprise round. The reference point for what “leading” looks like at the enterprise level. Not a consumer product.
• Sophos Intercept X: 100% detection, 86 of 90 technique-level detections in 2025. Strong execution-time blocking. Sophos publishes consumer Sophos Home and enterprise Intercept X from related codebases.
• Trend Micro Vision One: Participant in 2025 round. The most credible enterprise XDR from a vendor that also has a consumer product. The MITRE result for Trend Micro is published in the MITRE portal but not summarized in a press release at the time of this post.
• ESET: Participant in 2025 round. ESET PROTECT is the enterprise product; the consumer product shares the engine and a subset of the detection logic.
• Bitdefender: 91% analytic detection in the 2024 round, best alert-to-noise ratio of entrants. Participation in 2025 has not been confirmed in the December 2025 MITRE press release list.
• Microsoft Defender: Withdrew from 2025 round. Defenders of the Microsoft decision point to the Secure Future Initiative; critics point to a desire to avoid the methodology. Defender is in the prior 2024 round data.
• Norton, McAfee, Kaspersky: None of the three is listed in the 2025 round participants. The 2024 round had Kaspersky in the consumer track with strong results.

The MITRE result that matters for a consumer buyer is not the raw detection number. It is whether the vendor is willing to be tested by an independent third party on the most rigorous public test in the industry. Of the seven products in this post, Trend Micro and ESET chose to enter 2025. Bitdefender entered 2024. Microsoft withdrew. Norton, McAfee, and Kaspersky did not enter in the most recent rounds. That is a record a buyer can use, even without the detailed technique-level results.

The Kaspersky gap and what to do about it

The single biggest reason Kaspersky is not the recommendation in this post is the US regulatory situation. The engine quality is the best in the public lab data. The legal situation means a US reader cannot install a current version. A non-US reader has to make their own call based on jurisdiction.

For a US reader who wants the closest thing to the Kaspersky engine quality, the answer is Bitdefender, which is the next-best detection in the public data. For a non-US reader in a jurisdiction without an active warning, Kaspersky is still worth considering. The post does not recommend either of these paths as the default. The default recommendation is below.

Identity bundles, the second axis the post needs to address

The consumer AV suite in 2026 is not just an engine. It is a subscription that bundles an engine, a VPN, a password manager, an identity monitoring service, and insurance against the cost of identity theft. The Norton, McAfee, and McAfee+ products lean hardest into the identity bundle. The Trend Micro, Bitdefender, and ESET products lean into the engine. The post needs to address which is more useful for the kind of reader it is written for.

For readers who already use a separate identity service (1Password for password management, a credit monitoring service, a brokerage that includes identity insurance on the cash management account), the engine product is the right choice. The identity bundle in Norton or McAfee is convenient but redundant.

For readers who do not have a separate identity service and who are not going to set one up, the Norton or McAfee identity bundle is better than nothing. The Trend Micro Maximum Security, Bitdefender Total Security, and ESET HOME Security products do not include the identity layer, and the user has to source it separately.

For readers who live in a jurisdiction where Norton or McAfee identity insurance is not available, the choice reduces to the engine. That is the audience the post’s recommendation is built around.

The bottom line

The post’s recommendation for a single-device user who wants a product they can install and forget is Trend Micro Maximum Security. The product has the system impact profile, the Folder Shield ransomware coverage of cloud sync folders, the Pay Guard hardened browser for financial transactions, and the Smart Protection Network reputation engine that the post’s analysis finds most useful for the broadest set of readers. The 98.3% real world protection rate in the Feb-May 2026 AV-Comparatives round is Cluster 2 rather than Cluster 1, and the post is honest about that.

The post’s recommendation for a household or a user who has older hardware is the same Trend Micro Internet Security or Maximum Security product. The recommendation is not Norton, even though Norton has the highest detection rate in the lab data, because the Norton identity bundle introduces an attack surface that the post’s reader is unlikely to need. The recommendation is not McAfee, even though McAfee is the lightest paid consumer suite in the April 2026 performance test, because the McAfee bundling carries upgrade prompts and uninstall friction that the post’s reader will not enjoy. The recommendation is not Bitdefender, even though Bitdefender has the best false positive profile, because the system impact of 9.6 in the April 2026 performance test is too high for a non-technical user to tolerate without complaint. The recommendation is not Kaspersky, because the US regulatory situation makes a current version impossible. The recommendation is not ESET, because the configurability of the consumer product is more than the post’s reader wants. The recommendation is not Microsoft Defender, because the configuration is buried too deep and the user will not enable Controlled Folder Access on their own.

Trend Micro is the recommendation because it is the product that does the most useful work for the broadest set of readers with the least amount of user effort. The post will change the recommendation if the lab data changes, the regulatory situation changes, or the product changes. The next test round is in October 2026.

Geist verdict

The 2026 antivirus market is a market where the detection leaderboard is tighter than it has been in a decade. Cluster 1 and Cluster 2 are separated by less than 1.5 percentage points in the AV-Comparatives Feb-May 2026 round. The differences between products are in the things around the engine: system impact, identity bundle, configurability, free scanner, regulatory exposure, and how the company behaves when something goes wrong. The post’s reader is more likely to feel the difference in those things than in the detection rate.

For a single-device install that the reader will set up once and not touch, Trend Micro Maximum Security is the right choice. The 2026 product has the strongest combination of the layered engine, the cloud sync folder coverage, the hardened browser for financial transactions, the system impact profile, the Gartner Magic Quadrant recognition, and the long reputation network that the post’s research found. The post is willing to make the recommendation with the caveat that the lab data does not put Trend Micro on the top step of detection. The top step of detection is not the top step of usefulness.

Defensive checklist

1. Enable Controlled Folder Access on Windows Defender or the equivalent ransomware protection on whatever AV product you are running. The default is off on most consumer SKUs. The feature is the single highest-value setting on any consumer AV product in 2026.
2. Use a password manager that is not built into the antivirus subscription. The password manager inside Norton, McAfee, and Trend Micro is convenient. It is also a single point of failure if the AV vendor is breached. A standalone manager (Bitwarden, 1Password, KeePass) is harder to deploy but more resilient.
3. Enable MFA on every account that supports it. The single best identity protection in 2026 is not an identity monitoring service. It is the second factor on the accounts that matter.
4. Run an independent second-opinion scanner once a month. Trend Micro HouseCall is free. ESET Online Scanner is free. HitmanPro is free for 30 days. The point is to run an engine that is not the one on the machine and to look at the diff.
5. Read the renewal terms before you buy the first year. Every consumer AV suite in this post is sold at a 50-70% discount in year one and at full price in year two. The “Total Cost” of the subscription is roughly 1.7x the first-year price. Buyers who do not remember this get renewal shock.
6. Keep the product updated. A 2026 consumer AV suite that is six months out of date is not the same product as a current install. Auto-update should be on, and the user should check the version number once a quarter.
7. Disable the features you do not use. The bundled VPN, the bundled password manager, the bundled cloud backup. Each of these is an attack surface. The minimum feature set is antivirus, web protection, and ransomware protection. Everything else is opt-in.
