The 5 Best Antivirus for PC (2023 Update)

By Tibor Moes / Updated: September 2023

Do you need an antivirus program on your PC? Yes, you do. Your security and privacy are in danger.

  • Malware is everywhere: If you visit the wrong website, connect a USB stick, install free software, or open an email attachment, it might already be too late. You could have infected your PC with malware.
  • You can infect others: Some malware, like computer worms, are designed to spread. Once they are in your PC, they will automatically infect other computers and phones you connect with.
  • Your privacy is not guaranteed: Search engines, social networks, and other advertisers follow you across the web. They track what you visit, download, and watch so that they can show you personalized ads.

By buying the best antivirus for PC, you secure your devices, safeguard your privacy, and restore your peace of mind. Malware won’t be able to infect your devices. Advertisers won’t be able to track you online. Hackers can’t steal your passwords. And your children will be safe from dangerous websites.

Norton 360 Antivirus Review

Norton offers the best antivirus protection on all operating systems.


Norton is one of the few brands with a 100% malware protection score. Its real-time malware protection tool, called SONAR, is the best.

To get to this score, we averaged the last 10 test scores by AV-Test, an independent test lab. We also ran our own tests, during which Norton was able to detect malware attacks and phishing attempts in real-time.

Norton SONAR applies heuristic analysis and machine learning to spot known and unknown security risks. This means it identifies new threats through suspicious behavior rather than malicious computer code.


Norton’s Smart Firewall checks incoming and outgoing connections for suspicious behavior. It stops any attack before it becomes a problem.

By contrast, Windows’ firewall only checks incoming connections. It does not monitor whether the software on your computer makes suspicious outgoing connections to other devices.

And that’s not all. Norton’s firewall also cloaks inactive ports, so hackers can’t find them through hacking techniques like port scanning.


Norton’s unlimited VPN (Virtual Private Network) is outstanding. It is fast, secure (AES-256 & OpenVPN), private (no logs), allows torrenting (P2P), and features auto-connect, a kill switch, ad tracker blocking, and a split tunnel.

Most VPN services, like those by Bitdefender, have a daily data limit of 200 MB. To remove the data limit, you’ll have to pay extra. Norton, however, includes its unlimited VPN for free.

Password Manager

Norton’s password manager is excellent. Creating passwords is easy. Auto-filling them is accurate. And you can access your password vault using biometrics scanners (fingerprint or facial recognition).

Prices & Packages

  • Norton Antivirus Plus costs € 15 (Europe) or $ 20 (USA). It offers antivirus, a firewall, and a password manager. It protects 1 PC or Mac.
  • Norton 360 Standard costs € 30 (Europe) or $ 40 (USA). It adds a VPN and dark web monitoring. It protects 1 (Europe) or 3 (USA) devices.
  • Norton 360 Deluxe costs € 35 (Europe) or $ 50 (USA). It adds a privacy monitor and parental controls. It protects 5 devices.
  • Norton 360 Advanced costs € 40 in Europe and is not sold in the USA. It adds identity theft protection and protects 10 devices.
  • Norton 360 Select + LifeLock costs $ 99 in the USA and is not sold in Europe. It adds LifeLock identity theft protection and protects 10 devices.

In some countries, Norton 360 Advanced is called Norton 360 Premium. This is essentially the same product, without identity theft protection.

Bonus Features

  • Web protection: Block malicious websites via the Safe Web extension.
  • Cloud backup: Back up important files in secure cloud storage.
  • Parental controls: Monitor and protect your kids online.
  • Privacy monitor: Scan data brokers for your personal information.

  • Dark web monitoring: Scan the dark web for your personal information.
  • LifeLock identity theft protection: Discover and restore identity theft.

Note: Norton’s identity protection features are only available in the USA.

Conclusion: Is Norton the best antivirus software of 2023?

Yes, Norton is the best antivirus program in our test.

Modern security software needs to offer far more than just anti-malware protection. By combining device security, online privacy, and identity theft protection, Norton is the best internet security suite you can buy.

Bitdefender Antivirus Review

Bitdefender’s antivirus engine is famous for its outstanding protection, many security features, and multi-layer ransomware protection, while being light on system resources.


Bitdefender antivirus has a 95% malware protection score. This is the average of the 10 most recent protection tests by AV-Test. It puts Bitdefender ahead of all competitors, except Norton, McAfee, and Kaspersky.

Bitdefender’s real-time protection feature, Advanced Threat Defense, offers solid virus protection and advanced ransomware protection.

It does not rely on traditional malware detection methods, which use virus signatures. Instead, it continuously monitors the behavior of apps. The apps are blocked if Bitdefender spots an anomaly, such as code injection.

This method offers excellent malware detection rates while having a low number of false positives. During our own tests, Bitdefender detected the latest malware types instantly.


Bitdefender’s firewall can block inbound and outbound connections on local networks and the internet. On top of that, Bitdefender detects and blocks port scans that hackers use to find open ports on your device.


Bitdefender’s free VPN has a data limit of 200 MB / day. That equals 5 minutes of streaming at 720p or the opening of 100 websites.

Bitdefender uses Aura’s VPN tech but has built its own apps. The VPN is fast, secure (AES-256 & HydraVPN), private (no logs), allows torrenting, and has a few extra features: start-up, auto-connect, kill switch, and split tunneling.

You will have to buy Bitdefender Premium VPN or Bitdefender Premium Security, for unlimited data transmission.

Password Manager

Bitdefender’s password manager is sold separately. It is not included with Bitdefender Antivirus Plus, Internet Security, or Total Security. To get it, you have to buy it separately or buy Bitdefender Premium Security.

Prices & Packages

  • Bitdefender Antivirus Plus starts at € 15 (Europe) or $ 15 (USA). It offers antivirus and anti-phishing. It protects 1 to 10 PCs.
  • Bitdefender Internet Security starts at € 19 (Europe) or $ 25 (USA). It adds a firewall and parental controls. It protects 1 to 10 PCs.
  • Bitdefender Total Security starts at € 35 (Europe) or $ 40 (USA). It adds an optimizer and support for other OS. It protects 5 to 10 devices.
  • Bitdefender Premium Security starts at € 55 (Europe) or $ 60 (USA). It adds an unlimited VPN and password manager. It protects 10 devices.

Note: There is also Bitdefender Antivirus Free Edition, the free version of Antivirus Plus. This is the best free antivirus software. But honestly, it’s very basic and not much better than the built-in Microsoft Defender. So instead, we recommend Bitdefender’s paid antivirus software. It’s worth it.

Bonus Features

  • Online threat prevention: Anti-phishing protection for malicious sites.
  • Vulnerability scan: Scan the operating system, apps, and network.
  • Ransomware remediation: Restore files encrypted by ransomware.
  • Anti-spam: Customize anti-spam for Outlook and Thunderbird.
  • Safepay: Open a secure browser for online banking protection.
  • Video and audio protection: Webcam and microphone protection.
  • Anti-tracker: Remove tracking cookies via this browser extension.

  • Anti-theft: Locate and wipe your devices remotely.
  • One-click optimizer: Clean up your hard drive and browsers.
  • Data protection / file shredder: Permanently remove files.

Conclusion: Is Bitdefender the best antivirus software of 2023?

Bitdefender is one of the best antivirus software in our test. Its anti-malware, firewall, password manager, and VPN are highly advanced. On top of that, there are tons of extra features.

However, Bitdefender can be expensive. It sells its password manager and unlimited VPN separately or as part of its Premium Security suite. This makes it pricey if you want all security features.

By contrast, Norton includes these features for free.

You can try Bitdefender risk-free, thanks to its 30-day return policy.

  • Malware protection: 100%. McAfee averaged 6 out of 6 in the last 10 protection tests. It is excellent at detecting and removing malware.
  • Speed impact: 85%. McAfee averaged 5.85 out of 6 in the last 10 performance tests. So it has a minimal impact on your PC’s speed.
  • Features: 100%. McAfee offers anti-malware, anti-phishing, firewall, unlimited VPN, password manager, parental controls, and more.
  • Price: 95%. McAfee offers better value for money than most competitors, except Kaspersky, which is slightly cheaper.

McAfee Antivirus Review

McAfee allows you to protect an unlimited number of devices.


McAfee is among the few brands with a 100% anti-malware test score. It has improved its cybersecurity tools a lot in recent years. Since April 2020, it has achieved a perfect 100% score in every protection test by AV-Test.

In our tests, McAfee offered reliable protection against malicious software and cyber threats. Which means that it successfully detected and removed all offline and online threats.

McAfee can reach these results because of its Scan Engine:

  • It runs antivirus scans and matches files with malware samples.
  • It executes malicious code in a safe environment, called a sandbox.
  • It applies heuristic techniques to recognize new malicious threats.
  • It removes dangerous code from corrupted files.


McAfee’s excellent firewall filters both in- and outgoing traffic. On top of that, McAfee hides open ports so that hackers can’t identify unused ones with their port scanning techniques.


McAfee’s VPN, Safe Connect, is free and offers unlimited data. It’s fast, secure (AES-256), private (no activity logs), has servers in 45 countries, works with Netflix on many servers, and allows torrenting.

However, it’s not perfect. For instance, not all security features (like the kill switch and split tunnel) are available on all operating systems. And if you turn off auto-renew, the VPN is limited to 500 MB / day.

Password Manager

McAfee’s cross-platform password manager, True Key, is one of the best.

Creating and storing passwords is easy. Auto-filling them is accurate. And you can use biometrics (facial recognition and fingerprint scanner) to log in. As a result, it can compete with the best password managers, like Dashlane. 

Prices & Packages

  • McAfee Basic costs € 30 (Europe) or $ 30 (USA). It offers antivirus, anti-phishing, firewall, password manager, and VPN. It protects 1 device.
  • McAfee Essential (called McAfee Plus in Europe) costs € 40 (Europe) or $ 40 (USA). It adds no additional features but protects 5 devices.
  • McAfee+ Premium costs € 45 (Europe) or $ 45 (USA). It adds a personal data cleanup and protects unlimited devices.
  • McAfee+ Advanced costs € 65 (Europe) or $ 80 (USA). It adds identity theft protection and protects unlimited devices.
  • McAfee+ Ultimate costs $ 190 (USA) and is not sold in Europe. It adds more identity theft protection features and protects unlimited devices.

McAfee is in the process of renaming its products. So in some countries, you’ll be shown McAfee Total Protection instead, which has the same features as McAfee Basic and Essential.

Bonus Features

  • Secure Apps: A vulnerability scanner for security updates.
  • App Boost: A performance boost for apps you frequently use.
  • Browser Security: An anti-phishing browser extension.
  • Web Boost: A browser extension that stops videos from auto-playing.
  • Tracker Remover: A feature that deletes tracking cookies.
  • ID Protection: A dark web scanner for your personal data.
  • File Shredder: A shredder that can delete files securely.
  • File Lock: An app that creates password-protected file vaults.
  • Anti-Spam: An anti-spam feature for Outlook and Thunderbird.
  • Safe Family: A parental control feature to monitor and protect kids online.

Conclusion: Is McAfee the best antivirus software of 2023?

McAfee is one of the best antivirus software in our test. Its virus protection gets perfect scores, its password manager is excellent, its unlimited VPN is included for free, and its design is both user-friendly and beautiful.

On top of that, its premium and advanced plans allow you to protect an unlimited number of devices and offer extensive privacy and identity protection features, especially in the United States.

Panda Antivirus Review

Panda Review

Ranked #4 out of 28 Antivirus

Panda Antivirus on Windows 11


Panda offers excellent protection and has flexible pricing. However, it’s expensive if you want the unlimited VPN.

  • Malware protection: 99%. Panda averaged 99.9% in the malware protection tests. It is excellent at detecting and removing malware.
  • Speed impact: 99%. Panda averaged 99% in the performance tests. So it has almost no impact on your PC’s speed.
  • Features: 100%. Panda offers anti-malware, anti-phishing, firewall, unlimited VPN, password manager, parental controls, and more.
  • Price: 75%. Panda offers the most flexible pricing of all brands. But, if you want all the security features, Norton is more affordable.

Panda Dome Antivirus Review

Panda offers the most flexible pricing for its antivirus packages.


Panda antivirus scored 99.9% in the real-world protection tests. However, it does have with a higher number of false positives than its competitors, which means that it frequently mistakes harmless software for malware.

This result is the average of all tests by AV-Comparatives since 2020. Usually, we quote AV-Test, another independent test lab. However, Panda does not take part in their tests. Both labs independently test the malware scanning capabilities of free and premium antivirus programs.

Panda combines big data, artificial intelligence, and machine learning to scan all apps on your device. This allows it to counter known malware and advanced emerging threats like zero-day malware, ransomware, and API’s.


Panda’s firewall filters incoming and outgoing connections on local networks and the internet. It automatically assigns permissions to each application based on its risk level. But you can edit the rules per app.


Panda includes a free VPN with its antivirus products. However, this built-in VPN is limited to 150 MB / day, which isn’t a lot. That equals about 4 minutes of streaming at 720p or the opening of 75 websites.

Like Bitdefender, Panda’s VPN uses Aura’s technology. This means that the VPN is fast, secure (AES-256 & HydraVPN), private (no logs), and allows torrenting. However, it lacks extra features like a kill switch, making its € 50.00 price expensive.

Password Manager

Panda’s password manager is excellent. Generating and storing passwords is easy. Auto-filling them is accurate. And both two-factor authentification and biometrics login is supported.

The design of the browser extension for Google Chrome and Mozilla Firefox is identical to the apps on Android and iOS, which gives it a seamless experience across all major operating systems.

Prices & Packages

  • Panda Dome Essential starts at € 17 (Europe) or $ 24 (USA). It offers antivirus and a firewall.
  • Panda Dome Advanced starts at € 23 (Europe) or $ 28 (USA). It adds anti-phishing and parental controls.
  • Panda Dome Complete starts at € 35 (Europe) or $ 43 (USA). It adds a password manager and system optimizer.
  • Panda Dome Premium starts at € 60 (Europe) or $ 67 (USA). It adds an unlimited VPN and update manager.

All of Panda’s plans can be upscaled to an unlimited number of devices.

Bonus Features

  • Safe browsing: Block malicious URLs and phishing sites.
  • Dark web scanner: Search the dark web for your email address.
  • PC cleanup: Delete cookies or files with the system optimization tools.
  • Wi-Fi protection: Check and improve the security of your Wi-Fi network.
  • Anti-theft: Locate your PC if it is lost or stolen.
  • File encryptor: Encrypt sensitive files with a password.
  • File shredder: Securely and permanently delete files.
  • USB protection: Scan a USB drive for malware.

Conclusion: Is Panda the best antivirus software of 2023?

Panda is one of the best antivirus software in our test. We really like the password manager and flexible pricing.

But we prefer Norton, because it includes an unlimited VPN at a lower price. And because it offers better protection for Macs and mobile devices.

However, if you only have a Windows PC to protect, Panda’s excellent internet security suites are a great choice.

You can try Panda risk-free, thanks to its 30-day money-back guarantee.

Kaspersky Antivirus Review

Kaspersky Antivirus on Windows 11


Kaspersky has excellent protection at a low price. But the war in Ukraine raises concerns about its ties to the Russian government.

  • Malware protection: 100%. Kaspersky averaged 6 out of 6 in the last 10 protection tests. It is excellent at removing malware.
  • Speed impact: 100%. Kasperksy averaged 6 out of 6 in the last 10 performance tests. So it does not slow down your PC.
  • Features: 100%. Kaspersky has anti-malware, anti-phishing, firewall, unlimited VPN, password manager, parental controls, and more.
  • Price: 100%. Kaspersky Plus is the most affordable way to protect a Windows PC with all essential features, including an unlimited VPN.

Kaspersky Anti-Virus Review

Kaspersky offers exceptional online security at a low price.


Kaspersky antivirus has a 100% malware protection score. This was its average in the independent tests by AV-Test since October 2016. This puts it ahead of all other antivirus companies, except Norton and McAfee.

It can offer such excellent malware protection through its triple-layer protection system:

  • Locate vulnerabilities and threats proactively via heuristic analysis.
  • Block cyber threats in real-time.
  • Instantly isolate and remove dangers.


Kaspersky has one of the most advanced firewalls in the industry. It will filter incoming and outgoing network activity on local networks and the internet. And although it works perfectly on the default settings, there are plenty of customization options too.


Kaspersky includes an unlimited VPN for free with Plus and Premium.

Like Bitdefender’s VPN, it uses Aura’s technology. Therefore, the VPN is fast, secure (AES-256 & HydraVPN), and allows torrenting (P2P). It also features several extra features: Auto-connect, kill switch, smart protection, and website protection.

However, by default, Kaspersky will collect information on your device, location, VPN server, and WiFI network (including IP and DNS settings). It does this to improve product quality, send ads and create marketing offers.

Password Manager

Kaspersky’s password manager is excellent. Creating and storing passwords is easy, and auto-filling them is accurate. Unlike Norton and McAfee, Kaspersky’s password manager is a desktop app rather than a web app. But that doesn’t get in the way of a great user experience.

Prices & Packages

  • Kaspersky Standard starts at € 20 (Europe) or $ 28 (USA). It offers antivirus, anti-phishing, and a firewall. It protects 1 to 5 devices.
  • Kaspersky Plus starts at € 26 (Europe) or $ 37 (USA). It adds a firewall and an unlimited VPN. It protects 1 to 5 devices.
  • Kaspersky Premium starts at € 32 (Europe) or $ 48 (USA). It adds identity protection and parental controls. It protects 1 to 20 devices.

Kaspersky has replaced the old product names Kaspersky Anti-Virus, Internet Security, and Total Security, with Standard, Plus, and Premium.

Bonus Features

  • Internal scan: Scan for worms, spyware, rootkits, and other malware.
  • External scan: Scan external drives, like a hard disk or USB drive.
  • Vulnerability scan: Scan your device for security risks.
  • Kaspersky protection: A hardened browser extension for secure banking.
  • Parental controls: Monitor and protect your children online.
  • Webcam protection: Block programs from accessing your webcam.
  • Private browsing: Block and remove tracking cookies in your browser.
  • Backup and restore: Backup files to cloud backup storage.
  • File encryption: Lock sensitive files in a secure vault.
  • File shredder: Permanently delete files via advanced protocols.

Conclusion: Is Kaspersky the best antivirus software of 2023?

Kaspersky offers excellent antivirus protection. Its anti-malware is industry-leading, its firewall and password manager are excellent, and it provides a wide range of extra features.

However, its VPN privacy policy is disappointing. A VPN is a privacy product and shouldn’t be used for marketing. On top of that, Kaspersky struggles with the tensions between the West and Russia, due to the war in Ukraine.

Therefore, we prefer Norton, which includes an unlimited VPN for free in its antivirus suite, doesn’t track what you do online, and isn’t caught up in a geopolitical struggle.

You can try Kaspersky risk-free, thanks to its 30-day return policy.

Test score comparison

Our comparative study features the latest ten test scores from all antivirus brands, as conducted by AV-Test, a renowned German anti-malware testing agency. The evaluation is based on three criteria:

  • Protection (1-6): Antivirus protection against malware attacks.
  • Performance (1-6): System slowdown caused by the antivirus.
  • Usability (1-6): Frequency of false alarms and disruptions.

In calculating the overall score, we used their outcomes and this formula:

Final Score = 60% Protection + 20% Performance + 20% Usability.

Non-featured brands in the table did not participate in the AV-Test review, which is typically a red flag. Apart from Panda, ESET, and Sophos, most esteemed brands engage in these evaluations.

Final Score

Price comparison

We compared the pricing of the most popular antivirus solutions for Windows. In order to create a balanced comparison, we estimated the expense of securing a Windows PC with these key features:

  • Anti-malware
  • Anti-phishing (web protection)
  • Firewall
  • Password manager
  • Unlimited VPN (no data limit)

Please note:

  • Some brands lack certain features, diminishing their cost-effectiveness.
  • Prices shown are the rates for the second year in the USA, without considering first-year promotional offers.
  • Prices are approximated to the next dollar (e.g., $99.99 is rounded to $100) for simplicity.

Each brand may have different pricing outside the USA, which can be found on their respective websites.

User reviews

We’ve scrutinized the customer reviews for all antivirus brands, utilizing the scores and review quantity from TrustPilot, a reputable user feedback platform. However, we advise interpreting these results cautiously as some brands may actively seek to enhance their ratings.

We’re skeptical of unusually high ratings, particularly from brands like TotalAV, known for its assertive marketing and sales strategies.

We perceive scores ranging from 4.0 to 4.5 as commendable and realistic. Any score above this is questionable, while lower scores may suggest potential issues with the product or customer service. For example, the scores for McAfee raise some concerns.

What is antivirus software?

Antivirus software is a type of computer program designed to safeguard your computer or network from cybersecurity threats. These threats include viruses, worms, trojans, ransomware, spyware, adware, and other types of malicious software, collectively known as malware.

Antivirus software functions as the first line of defense, acting as a sentinel that continuously monitors for potential threats. It is also responsible for quarantining and eliminating any detected threats, protecting your system’s data integrity and user privacy. Beyond these protective measures, modern antivirus software also offers additional features such as firewalls, email protection, and safe browsing tools.

For more, read our blog post on what antivirus software is.

How does antivirus software work?

Antivirus software uses various methods to detect and neutralize threats. It primarily relies on three mechanisms: signature-based detection, heuristic analysis, and behavior-based detection. Each of these mechanisms provides a unique approach to identifying potential threats.

Signature-based detection

Signature-based detection is one of the earliest and most straightforward methods employed by antivirus software. Each piece of malware has a unique piece of code or “signature” that distinguishes it from others. Antivirus software maintains a vast database of these known malware signatures.

When a file or program is accessed, the antivirus software scans it, comparing its code against the database of known malware signatures. If it finds a match, it flags the file or program as a threat. This method is highly effective at detecting and removing known malware but falls short when it comes to new, unknown malware variants, also known as zero-day threats.

Heuristic analysis

To overcome the limitations of signature-based detection, antivirus programs use heuristic analysis. Instead of looking for a specific signature, heuristic analysis aims to identify previously unknown malware or new variants of known malware by examining the file’s structure and behavior.

The software dissects the suspect file, examining the code for behaviors or instructions that are commonly associated with malware, such as code that attempts to modify system files or transmit data to an external server. While this method significantly improves detection rates for new malware, it is also more prone to false positives – flagging legitimate programs as potential threats.

Behavior-based detection

Behavior-based detection, also known as behavior blocking, goes beyond static code analysis. It monitors the behavior of applications in real-time. If a program starts to exhibit suspicious behavior, such as trying to access protected files or modify system settings, the antivirus software flags it as potentially malicious and takes appropriate action.

This method is particularly effective against malware that may evade signature and heuristic analysis, such as polymorphic or metamorphic viruses that can alter their code to avoid detection. Behavior-based detection is also helpful against sophisticated threats like rootkits or fileless malware that reside in system memory instead of installing themselves as regular files.

It’s worth noting that while behavior-based detection can detect previously unknown threats, it may also produce false positives, and hence, should be combined with other methods to ensure accuracy and reliability.

Does a PC need antivirus software?

Does a PC Need Antivirus Software?

A PC, or Personal Computer, is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by an end user, rather than by a computer expert or technician. They are powered by various operating systems, such as Microsoft Windows, Apple’s macOS, and Linux distributions, among others.

Particularly when it comes to Windows-powered PCs, there is a pressing need for antivirus software. Windows holds a substantial market share in the global operating system landscape, making it a popular target for cybercriminals.
