31 Best Antivirus Software in 2026

Norton 360 is consistently rated the best overall consumer antivirus in 2026 by independent reviewers. Owned by Gen Digital (which also owns Avast, AVG, and Avira), Norton achieves a 100% real-time threat detection rate in AV-TEST evaluations. Every plan from Standard upward includes an unlimited-data VPN, password manager, dark web monitoring, and cloud backup. The 60-day money-back guarantee is one of the most generous in the category. Norton Power Eraser removes rootkit-level threats other scanners miss. LifeLock identity theft protection is available on premium US plans.

Bitdefender is rated the top antivirus by TechRadar and AV-Comparatives in 2026 for its combination of near-perfect malware detection and minimal performance impact. It received a Top-Rated Product Award from AV-Comparatives in their 2025 Consumer Main-Test Series, earning five Advanced+ awards across seven test categories. A free Windows-only tier provides real-time protection. Total Security supports up to three devices and adds parental controls, webcam protection, and Performance Profiles. The 200 MB/day VPN limit on most plans is a notable restriction.

Kaspersky achieves a 100% malware detection rate in AV-TEST April 2025 evaluations and was named a Top-Rated Product by AV-Comparatives in their 2025 Consumer Main-Test Series alongside Bitdefender. However, Bloomberg reported in 2022 that Kaspersky Lab had provided the FSB (Russia's Federal Security Service) with real-time customer intelligence, and the US government issued a formal advisory the same year recommending its removal from systems. Kaspersky's technical performance remains among the highest of any consumer antivirus, but the Russian ownership and government intelligence concerns are documented and well-publicised.

McAfee Total Protection is a well-rounded consumer security suite particularly strong on mobile (iOS and Android) and identity theft protection. It achieved a 100% malware detection rate in AV-Comparatives 2025 Consumer testing. The Total Protection plan covers unlimited devices under one subscription. True Key password manager, unlimited VPN, and an identity theft monitoring Protection Score dashboard are all included. System slowdown during full scans is more pronounced than Bitdefender. The Safe Family parental controls are strong for households with children across multiple devices.

Malwarebytes built its reputation as the best emergency malware removal tool and has evolved into a full consumer antivirus suite. It achieves a 99.88% protection score from AV-Comparatives but is not tested by AV-TEST, making independent lab comparison incomplete. Its anti-exploit protection blocks browser and application exploit attacks before malware can execute. Browser Guard blocks malicious ads, trackers, and phishing URLs. The identity protection tier adds $2 million identity theft insurance. Pricing is higher than most comparably-featured suites: Standard starts at $44.99/year for one device.

Avast offers the most feature-complete free antivirus on the market, including real-time scanning, phishing defence, a built-in firewall, and ransomware protection at no cost. It earned a Top-Rated Product Award from AV-Comparatives in their 2025 Consumer Main-Test Series and near-perfect AV-TEST scores. Avast is owned by Gen Digital (same company as Norton, AVG, and Avira). A 2020 data-sharing scandal in which Avast's subsidiary Jumpshot sold user browsing data to advertisers damaged its reputation, though the subsidiary was shut down. The paid tiers add a sandbox, VPN, and webcam protection.

AVG is a sister product to Avast under Gen Digital ownership, sharing core detection technology and achieving identical AV-Comparatives Top-Rated Product status in 2025. The free tier provides real-time protection, an email scanner, and a performance scanner. AVG and Avast are developed by separate engineering teams within Gen Digital, which the company uses to maintain two different product personalities aimed at different consumer segments. AVG is positioned as simpler and less feature-heavy than Avast in the free tier. The paid AVG Internet Security and Ultimate tiers are structurally similar to Avast's paid plans.

ESET consistently earns the highest user satisfaction ratings of any consumer antivirus: 4.6 out of 5 on independent review platforms in 2026. It received a perfect 6/6 score across all AV-TEST categories in August 2025 evaluations and a Top-Rated AV-Comparatives 2025 award. ESET does not practice aggressive auto-renewal, which AV-Comparatives specifically called out as commendable in their 2025 summary. The interface is clean and highly configurable, well-suited to technically-minded users. ESET HOME Security Essential starts at $39.99/year for one device.

Trend Micro is a well-established Japanese cybersecurity company with a strong mid-market antivirus offering. It received an AV-Comparatives Standard award in the 2025 Consumer Main-Test Series and near-perfect AV-TEST scores. Pay Guard provides a hardened browser for online transactions. Folder Shield protects specific directories from ransomware encryption. The Maximum Security suite includes a password manager and 5-device coverage. Trend Micro does not score as highly as Bitdefender or ESET in independent lab benchmarks, but provides reliable protection at a mid-range price.

Sophos Home is the consumer version of Sophos, which is primarily an enterprise cybersecurity company. Its central web dashboard allows one user to remotely manage protection across up to 10 devices, making it unusually practical for families and small offices. AI-powered threat detection leverages Sophos's enterprise threat intelligence network. Web filtering blocks malicious and inappropriate content. The free tier provides core antivirus protection for one device. Sophos Home is not regularly tested by AV-TEST or AV-Comparatives for the consumer product, which limits independent benchmark comparison.

Avira is a German-origin antivirus brand now owned by Gen Digital (the same company as Norton, Avast, and AVG). It received a Bronze Award from AV-Comparatives in both the Real-World Protection Test and Advanced Threat Protection category in 2025. Avira Free Security is one of the most feature-complete free tiers available, including a VPN (500 MB/month), password manager, and performance optimiser alongside core antivirus. Avira Prime includes an unlimited VPN and Identity Assistant for monitoring personal data exposure. Monthly billing is available, unlike most competitors that require annual commitments.

BullGuard was an independent Danish antivirus brand that was acquired by NortonLifeLock (now Gen Digital) in 2022 and subsequently discontinued as a standalone product. Existing BullGuard subscribers were migrated to Norton 360. BullGuard's notable features at the time of acquisition included a Game Booster that maintained gaming performance, triple-layer protection, and an advanced firewall. The brand no longer exists as a separate purchasable product.

ZoneAlarm is a consumer security product made by Check Point Software, the enterprise firewall company. It was historically known for being one of the earliest personal firewall products in the late 1990s. ZoneAlarm Extreme Security provides antivirus, a two-way firewall, identity theft protection, and anti-ransomware. The antivirus engine is licensed from Kaspersky, which carries the same ownership concerns. ZoneAlarm Anti-Ransomware is available as a standalone product. The product is less commonly recommended in current independent reviews compared to the top-tier consumer suites.

Webroot is a cloud-first antivirus that stores almost all detection data in the cloud rather than on the local device, resulting in the fastest scan speeds of any consumer antivirus product. A full system scan typically completes in under two minutes versus 30 to 60 minutes for competitors. The database is updated continuously without requiring local definition downloads. The 70-day money-back guarantee is the longest in the category. Webroot is owned by OpenText (formerly Carbonite). Independent lab test data is limited: Webroot's last major AV-TEST participation was in 2019.

PC Matic uses an allowlist (whitelist) approach instead of the standard threat-signature blacklist model: only applications on PC Matic's verified global allowlist are permitted to run. Everything else is blocked by default. This approach eliminates zero-day threats from unknown applications entirely. The approach also generates false positives for legitimate but uncommon software. PC Matic is US-based and US-owned, which it markets as a differentiator from foreign-owned vendors. A lifetime plan is available at $150 one-time, one of the few true lifetime antivirus licences available.

TotalAV is a budget consumer antivirus that consistently earns high user satisfaction scores (4.7/5 on Trustpilot from 131,500 reviews). It uses Avira's antivirus engine under licence, providing solid detection quality. System optimisation tools including junk cleaner, startup manager, and browser cleanup are included alongside core antivirus. An identity monitoring module covers data breach alerts and $1 million identity theft insurance on the top tier. TotalAV is frequently offered at heavy introductory discounts, though renewal pricing increases significantly.

Intego is the most recommended antivirus specifically designed for macOS, receiving strong marks from Mac-focused independent reviewers. Unlike cross-platform vendors that adapted Windows antivirus to Mac, Intego built its product exclusively for macOS from the ground up. VirusBarrier is its core scanning engine. NetBarrier is a two-way Mac firewall. ContentBarrier provides parental controls. Intego has expanded to Windows with a separate product. AV-TEST specifically tested Intego for Mac and it scored well. Intego does not include a VPN unless bundled separately.

VIPRE is a Florida-based antivirus that earned an AV-Comparatives Standard award in 2025 with a 99.83% protection score and 94th-percentile performance rating. It is designed with minimal interface clutter and no bundled toolbars or unnecessary third-party software. VIPRE's detection uses both signature and behaviour-based analysis. US-based customer support is a marketing differentiator. VPN and dark web scanning are locked to the Ultimate Security Bundle tier only. Pricing starts at $14.99/year for the first year, with steep renewal increases.

G DATA is a German cybersecurity company founded in 1987 that earned a Top-Rated Product Award from AV-Comparatives in the 2025 Consumer Main-Test Series, one of only seven products to do so. AV-Comparatives specifically noted that G DATA is one of the few vendors that does not force auto-renewal on customers, commending this as best practice. G DATA uses a dual-engine scanning system combining its own engine with a secondary engine for higher detection confidence. Based in Bochum, Germany, it is an EU jurisdiction product.

Comodo is a US-based cybersecurity company offering a free antivirus with a distinctive default-deny sandbox architecture called Auto-Containment. Any unknown application is automatically run inside a contained virtual environment before being allowed access to the real system. This architecture theoretically provides strong zero-day protection by preventing unknown executables from affecting the host system. Comodo is not currently tested in AV-TEST or AV-Comparatives consumer series. The free version provides the sandbox containment alongside basic signature-based detection.

Panda Security is a Spanish cybersecurity brand owned by WatchGuard Technologies. It uses a cloud-first detection model with a free tier providing real-time protection with no data cap. Panda earned an AV-TEST Top Product certification in 2025 in the performance test series. USB vaccination prevents auto-run malware from executing when infected USB drives are connected. The paid Dome tiers add a VPN, firewall, parental controls, and Wi-Fi protection. Panda is not included in AV-Comparatives consumer main-test series regularly.

CrowdStrike Falcon is the dominant cloud-native enterprise endpoint detection and response (EDR) platform, with over 11% market mindshare in the enterprise EPP category as of early 2026. The Falcon platform uses AI and machine learning for real-time threat detection, OverWatch managed threat hunting, and XDR correlation across endpoint, identity, and cloud workloads. Pricing ranges from $59.99 to $184.99 per device per year across Go, Pro, and Enterprise tiers. CrowdStrike gained significant negotiating leverage following the July 2024 global outage that impacted 8.5 million Windows systems, with buyers reporting 40-92% discount negotiations as a result.

SentinelOne Singularity is the primary challenger to CrowdStrike in the enterprise EDR market, claiming a 3.5-minute mean time to detect versus CrowdStrike's 4 minutes in MITRE ATT&CK Enterprise Round 6 (2024) evaluation. The platform uses a local AI agent that operates without cloud connectivity, providing full protection offline. Purple AI offers natural-language threat investigation queries included in the Complete tier. SentinelOne consistently prices 50-67% lower than CrowdStrike list prices, which it uses as a direct sales differentiator. Most organisations deploy at the Complete tier at approximately $135-$153 per endpoint after typical 15-25% negotiation discount.

Cylance was the first endpoint security vendor to build an AI/ML-only threat prevention engine with no signature files, no cloud connectivity required, and no behavioural analysis overhead. Acquired by BlackBerry in 2019, the product continues as CylancePROTECT with additional XDR capabilities under the BlackBerry Cybersecurity brand. CylancePROTECT claims 99.7%+ threat detection using pre-execution AI analysis alone. Average pricing is approximately $60 per device per year, positioning it as a cost-competitive option relative to CrowdStrike and SentinelOne at their standard tiers.

VMware Carbon Black Endpoint was acquired by Broadcom as part of its $61 billion VMware acquisition completed in 2023. Carbon Black is an enterprise NGAV and EDR platform combining signature-free prevention with deep process event recording for behavioural analysis and threat hunting. Continuous recording creates a searchable history of all endpoint activity. Carbon Black Cloud Endpoint Standard provides the NGAV layer, while Enterprise adds full EDR, and Enterprise EDR adds forensic investigation capabilities. Integration with VMware's virtualisation infrastructure is a differentiator for enterprises already running VMware environments.

Fortinet FortiClient is an enterprise endpoint security agent tightly integrated with Fortinet's FortiGate firewall and Security Fabric ecosystem. Its key differentiator is automated quarantine: when FortiClient detects malware on an endpoint, it can automatically signal the connected FortiGate firewall to block that device at the network switch port level, physically isolating it from the rest of the network. FortiEDR provides lightweight pre-infection blocking suitable for legacy POS systems, IoT devices, and manufacturing environments. FortiClient EMS (Endpoint Management Server) provides centralised management across all agent deployments.

Check Point Software Technologies is the company that invented the commercial stateful packet inspection firewall in 1994. Its Harmony Endpoint product is the enterprise endpoint component of Check Point's Infinity platform. Harmony Endpoint provides NGAV, EDR, and XDR capabilities. Check Point's competitive positioning emphasises prevention-first architecture over detection-and-response. Cortex XDR (Palo Alto) and Harmony Endpoint are commonly compared in enterprise evaluations. Check Point's Threat Intelligence cloud, ThreatCloud AI, aggregates data from over 150,000 connected gateways worldwide.

Palo Alto Networks Cortex XDR was the industry's first platform to natively integrate endpoint, network (firewall), and cloud data into a single automated detection engine. The Cortex platform includes Cortex XDR (detection and response), Cortex XSIAM (AI-driven SOC automation), and Unit 42 Managed Detection and Response. Unit 42 is one of the most respected threat intelligence teams in enterprise security. Cortex is positioned as a premium AI-driven platform above CrowdStrike's price point in most enterprise comparisons, with NGFW pricing starting around $1,000 for the PA-220 hardware model.

Symantec was one of the most widely deployed enterprise endpoint security products before being acquired by Broadcom in 2019 for $10.7 billion. It continues as Symantec Endpoint Security (SES) Complete under Broadcom's ownership. The product is particularly valued by banks, governments, and large enterprises for securing complex hybrid cloud environments that span on-premises servers and cloud workloads. SES Complete combines traditional antivirus, hardening, deception technology, and modern EDR capabilities. Broadcom's acquisition strategy prioritises large enterprise customers, with smaller customers often being redirected to resellers.

ClamAV is a free, open-source, cross-platform antivirus toolkit maintained by Cisco Talos. It is the dominant antivirus engine for Linux mail servers, network gateways, and NAS devices. ClamAV operates entirely via command line with no graphical interface: it is designed for system administrators, not end users. On Linux, ClamAV is the practical standard for mail server scanning. On Windows and macOS, the lack of a GUI and complex setup process make it unsuitable for most end users. ClamTK is a third-party graphical front-end for ClamAV available on Linux. Detection rates in independent testing range from 60-90%, below the top commercial products.

VirusTotal is a free online file and URL scanning service owned by Google (Alphabet). When a file or URL is submitted, VirusTotal analyses it against over 70 antivirus engines simultaneously and returns all results. This makes it the single most useful tool for determining whether a file or URL is considered malicious by the security community. VirusTotal is not a standalone antivirus product and provides no real-time protection. It is a threat analysis and intelligence lookup tool. Enterprise users can access the VirusTotal Intelligence and Enterprise API for bulk analysis, threat hunting, and integration into security operations workflows.
