How do you choose a good antivirus, especially if your device isn’t infected? Do you look at how quickly the company updates databases or if it includes extra tools like identity protection? Thankfully, our team of experts knows exactly what to look for and how to assess the effectiveness of antivirus products.
We ran multiple tests, including the EICAR malware test file, on 40 antivirus apps. TotalAV is the standout, but there are several others worth considering. We’ve categorized the best options for different needs so you can choose the right one. Let’s take a look at the list.

Antivirus Terms Explained: Antiviruses scan for malware in two ways. “On-access scans” run in the background whenever the software is active — this is also known as “real-time protection.” Meanwhile, “on-demand scans” are initiated by the user.

1. Norton Antivirus - The Best Cross-Platform Antivirus Software
View Plans Links to Norton.com
Product Specs
Virus Detection Yes Malware Detection Yes Firewall Yes Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring Yes
Who Norton Antivirus Plus Is Best For
Norton 360 works across multiple platforms, and also has feature-rich apps. We recommend installing and using antivirus software on all your devices, from computers to smartphones. For that, you’ll need an antivirus with great cross-platform support, which is exactly what we saw from Norton. We had no trouble using its apps across a variety of devices and operating systems.
Pros
- Affordable introductory prices
- 24/7 phone and live chat support
- Intuitive apps for Windows, macOS, Android, and iOS
- Lots of extras (cloud backup, parental control features, etc.)
Cons
- Prices can double or more after the first year
- The password manager is a separate app
- Offers device optimization, but as a separate service
Malware Detection – Excellent
Norton Antivirus Plus has great malware detection and protection rates. It detected all the malware test files we threw at it. It also maintains a nearly 100% detection and protection rate on AV-TEST’s platform. We also like that it includes protection against ransomware, just like TotalAV.
Additionally, Norton Antivirus Plus specializes against zero-day exploits (when hackers exploit newly discovered vulnerabilities). It does this via a combination of antivirus and VPN protection, along with a firewall. That said, we think TotalAV handles this better with its next-gen cloud scanning, which analyzes suspicious files in real-time.
Why That’s Important: Zero-day exploits are hard to detect because they typically aren’t in malware databases yet. That’s why they have a high success rate.3 Antivirus programs that rely only on databases of known malware have a slimmer chance of detecting zero-day attacks.
User Experience – Excellent
Norton 360 is simple to navigate and use, whether you’re on mobile or desktop. Norton Antivirus Plus offers protection for Windows, macOS, Android, and iOS devices. You can even install it on ten devices with the highest-tier subscription. We recommend this plan if you own a lot of devices or live in a large household.
We also found the Norton Antivirus Plus apps beginner-friendly. Navigating the interface was simple and there were useful explanations in plain-language for all settings and features.
Price – Very Good
Families should consider the “Norton 360 with LifeLock Select Plus” subscription. It covers up to 10 devices and provides a decent level of identity theft protection. If you only need to protect a couple of devices and don’t need identity theft protection, the “Norton 360 Deluxe” subscription is a great pick.
There isn’t a free version of Norton Antivirus Plus available, but there is a free 14-day trial. Even if you can’t decide after two weeks, all plans have a 60-day money-back guarantee.

2. Aura Antivirus - The Best Antivirus with Identity Protection
View Packages Links to Aura Antivirus
Product Specs
Virus Detection Yes Malware Detection Yes Firewall No Full, quick, and scheduled scans No scheduled scans Real-time protection Yes Behavior-based monitoring No
Who Aura Antivirus Is Best For
All three of Aura’s antivirus tiers offer great value. Their lowest tier at $3 per month includes their full antivirus capabilities and a VPN for up to three devices. From there, Aura includes identity protection capabilities and even $1 million identity theft insurance in their $5 per month premium tier. We recommend the top-tier plan for its identity protection, especially after testing Aura’s dedicated ID theft protection service.
What We Like
- Affordable plans that offer a lot of value
- Long 60-day money-back guarantee
- Comprehensive malware scanning and automatic malware quarantining
- Credit monitoring and identity protections included in premium plan
What We Don’t Like
- Only available in annual plans
- Real-time threat detection is only available for Windows devices
- Basic plan only covers three devices
Malware Detection – Very Good
During Aura’s complete scan of our device, it checked over 20,000 files and found six potential threats. Aura hasn’t been rigorously tested by third-party authorities yet, being new to the industry. We still ran our tests. Like TotalAV, Aura blocked every EICAR malware test file download attempt. Our team also ran Anti-Malware Standards Testing Organization’s malware detection tests, which Aura aced.
User Experience – Very Good
You wouldn’t guess that Aura is new to the antivirus industry. The installation process was straightforward and the app made it easy to schedule scans or run one manually. Seasoned antivirus users might miss the customization options, our test results show they aren’t necessary.
Pro Tip: We recommend running full scans on a weekly basis and quick scans on a daily basis. Since Aura Antivirus is a lightweight program, it can easily run these scans in the background as you use your device like normal.
Price – Excellent
Aura offers a 14-day free trial you can use to test out their full lineup of protections and services. Aura’s starting price of $3 per month is already one of the most cost-effective antivirus plans out there. In that plan, they include a VPN too, but it only covers three devices at most.
Where we find Aura provides the most value, though, is with their Ultimate plan at $5 per month. It includes $1 million identity theft insurance, comprehensive identity protections, and credit monitoring. Their insurance is so good that Aura made our list of the best identity restoration services.

3. TotalAV Antivirus - The Best Antivirus for Malware Protection
View Packages Links to TotalAV Antivirus
Product Specs
Virus Detection Yes Malware Detection Yes Firewall No Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring No
Who TotalAV Is Best For
TotalAV got high marks in all the malware tests we ran. TotalAV nailed our malware detection tests and scored well in antivirus tests from independent security firms. We like that TotalAV automatically updates its malware definition database and offers real-time protection. Our team even tried out the clean-up tool and was impressed how much faster our devices run now. It’s a nice bonus on top of antivirus protection.
Pros
- Real-time protection and manual scans
- Has a very good system clean-up tool
- Automatic malware definition database updates
- Smart Scan goes beyond just scanning for malware
Cons
- Lacks a firewall
- Has a free version, but it’s pretty limited
- Prices increase after the first year
Malware Detection – Excellent
TotalAV successfully blocked a website with malicious activities. We used the EICAR malware test file to test TotalAV. Antiviruses typically flag this file as malware, but it’s actually harmless.1 We tried downloading this file a total of 10 times, and TotalAV blocked it every time. It also detected the test files we tried to sneak in via a USB flash drive and local area network (LAN) file transfers.
TotalAV also performed very well in tests run by AV-TEST (an independent firm that runs comprehensive antivirus tests).2 Their results show that TotalAV maintains a near 100% malware detection and protection rate across Windows, macOS, and Android devices.
User Experience – Excellent
TotalAV offers native apps for Windows, macOS, Android, and iOS. They are easy to set up and don’t take up a lot of space. We installed every app and didn’t notice any significant performance issues while running full scans in the background.
On Windows and Android, TotalAV provides access to system clean-up tools. For example, on Windows, you can use the antivirus app to scan your PC junk files, tracking cookies, and startup programs that might be slowing it down. We ran several clean-up scans, and TotalAV usually finished them in less than a minute.

Price – Very Good
TotalAV offers several tier-based subscriptions, including bundles with additional security services such as a VPN (Virtual Private Network) and password manager. We signed up for the “TotalAV Total Security” subscription to get access to all features. It’s priced at $49 for the first year — about $4 per month.
You get a 30-day refund if you change your mind. We recommend checking out the free version to see if it suits your needs. Keep in mind that TotalAV’s free mode doesn’t include real-time protection. That means you have to run manual scans regularly to keep your device safe.

4. Guardio - The Best Antivirus Browser Extension
View Plans Links to Guardio
Product Specs
Virus Detection Yes Malware Detection Yes Firewall No Full, quick, and scheduled scans No Real-time protection Yes (browser-based) Behavior-based monitoring Yes
Who Guardio Is Best For
Guardio doesn’t come packaged with a ton of other digital security tools you may or may not use. It’s a browser extension that defends against the place where viruses are likely to come from: the internet. As of today, it’s available as a browser extension for Chrome users and a mobile app. You heavily use the internet, Guardio is a lightweight but reliable antivirus for you.
>> Learn More: The Complete Guide to Private Browsers
What We Like
- Easy to install in chrome
- Includes data breach monitoring for emails and phone numbers
- Phishing protection for Gmail
- Doesn’t take up a lot of hard drive space
What We Don’t Like
- Only works with Chrome browsers
- Doesn’t perform total system scans
- Can’t remove viruses or malware
Malware Detection – Good
We tested Guardio by visiting some questionable websites, and it blocked most of them. Since Guardio doesn’t scan desktops, we put it through its paces by visiting websites flagged by CERT, which updates its records 24/7. Guardio caught about 80 percent of them. It missed a couple that offer fake sweepstakes, maybe because it didn’t download any malicious files.
The mobile app offers complete device protection. Guardio blocked all our attempts to download viruses onto our Pixel, but it wasn’t as successful with zipped files. We also noticed it actively monitors Google Play’s catalog of extensions and blocks the dangerous ones from infecting your device.
FYI: Keep in mind that Guardio can’t remove viruses. It only flags or blocks them. If you have an infected device, we recommend choosing another antivirus app on this list.
User Experience – Very Good
Getting started with Guardio was easy. We installed it like any other browser extension, signed up to a subscription, and let it do its thing in the background. Guardio only popped up when it detected something malicious and helped us back to safety. The only other interaction we had with Guardio was checking out the dashboard to review our browsing activity and the email security features.
FYI: Guardio can scan the dark web and send alerts if it finds anything. It can’t remove your details, but the notifications are helpful so you can update passwords or monitor bank accounts more closely.
Price – Good
All paid Guardio subscriptions include mobile and desktop browser protection. Guardio offers a free plan that includes basic browser protection and a manual security scan. We recommend the paid options though, which start at $9.99 per month on a yearly subscription. Guardio also has a package for couples and one for five people. It’s a good option for students who want to chip in for antivirus protection or large families with a lot of devices.
While we like that Guardio is first and foremost an antivirus protector, the prices are a little expensive compared to TotalAV and Aura. Especially considering Guardio doesn’t remove viruses or include other digital security tools. Despite these minor gripes, it’s a reliable browser extension we trust to keep us safe from questionable websites.

5. Surfshark Antivirus - The Best Antivirus For All-Around Digital Security
View Plans Links to Surfshark.com
Product Specs
Virus Detection Yes Malware Detection Yes Firewall No Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring Yes
Who Surfshark Antivirus Is Best For
Surfshark is fast, effective, and user-friendly. A Surfshark One subscription doesn’t just remove malware and viruses. You’ll get comprehensive digital security with one of the best VPNs on the market and a top-rated data removal service.
>> Read More: Surfshark VPN Review
Pros
- Built-in access to an antivirus, a VPN, data breach monitoring, and more
- 24/7 live chat support
- Scheduled, quick, and full scans
- Regular automatic updates of virus database
Cons
- The antivirus isn’t available on iOS devices
- Doesn’t have a firewall
- Doesn’t provide access to system clean-up tools
Malware Detection – Very Good
Surfshark successfully blocked our attempt to download the EICAR malware test file and prevented access to unsafe links. We ran manual scans on our Windows laptop, and Surfshark found most of our malware test files. It only missed the one hidden in a .zip file.
While we’re happy with Surfshark’s malware detection and protection, it currently lacks the extra protections that Norton and TotalAV offers. Ransomware protection is one example.
Expert Tip: We recommend backing up your most important files to an encrypted cloud server to protect yourself from ransomware. This way you’ll have a copy of everything if you get locked out of your computer.
User Experience – Very Good
We found Surfshark’s all-in-one app very intuitive. Surfshark Antivirus has apps for Windows, macOS, and Android, and we like that it uses the same app for all its security services. We found the app easy to navigate, similar to Norton. With tabs along the left margin dedicated to each service (see our screenshot above), we always found it easy to navigate to the features we need.
What holds back Surfshark from being higher on the list is the lack of antivirus features for the iOS and iPadOS apps. We would also like to see a device optimization tool, similar to TotalAV’s.
Price – Very Good
Surfshark has several tier-based subscriptions. We recommend getting “Surfshark One,” since it includes the antivirus, the VPN, a tool that lets you generate an alternative email and persona, data breach monitoring, and a privacy-focused search engine. We also recommend choosing a longer subscription, as the monthly average cost can go down to $2.49. Also, check out our Surfshark deals page.
“Surfshark One” Subscription Costs 1-Month Plan $12.99/month 1-Year Plan $3.39/month 2-Year Plan $2.49/month >> Related Reading: How Much Does Surfshark Cost in 2025?

6. McAfee Antivirus - The Best Antivirus for Families
View Plans Links to McAfee Antivirus
Product Specs
Virus Detection Yes Malware Detection Yes Firewall Yes Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring Yes
Who McAfee Is Best For
McAfee offers great plans for families, and is also simple to use. McAfee offers three subscriptions tailored for families. Each one offers antivirus protection and a full-featured VPN. McAfee’s top family plan even adds identity theft protection features. The best part is the subscriptions cover unlimited devices, so no one has to fight over who gets to install the app.
Pros
- Antivirus packages with VPN, identity protection, and more
- Real-time detection of threats
- Some subscriptions secure an unlimited number of devices
- Easy-to-navigate apps
Cons
- Lengthy scans
- Real-time and background scans affected system performance
- Frequent notifications when you turn off some features
Malware Detection – Very Good
McAfee quickly found and quarantined malware test files. During testing, McAfee’s real-time protection instantly blocked every malware test file we tried to download. We also loaded one computer with test files, and after installing McAfee, its full scan (which took a couple of hours) successfully found those files.
What we liked best, though, is McAfee’s built-in firewall, which enhances your home’s network security. Essentially, it prevents malware from spreading to your family’s devices through your network — useful if you have teenagers constantly online.
>> See What We Recommend: The Best Antivirus With Firewall
User Experience – Good
McAfee offers good cross-platform compatibility since it works on Windows, macOS, Android, iOS, and ChromeOS. We also found McAfee’s apps easy to install and use, making it ideal for family members not familiar with using antivirus software. With real-time protection on, there’s no need for manual scans.
That said, McAfee’s apps are not as lightweight as Aura’s, Guardio’s, or Surfshark’s. On-going scans impacted our system’s performance, and some scans took more than two hours to finish.
Our Experience: After turning on real-time protection on a 2023 high-end Windows laptop, we noticed that files loaded slower than normal. We also experienced minimal lag when playing graphics-intensive video games.
Price – Very Good
The “McAfee Advanced Family” subscription is a good choice for most families. It includes antivirus, a VPN, a password manager, and identity theft protection. In fact, we think that McAfee offers one of the best identity theft protection services in 2025.
The “McAfee Advanced Family” subscription costs $119.99 for the first year. If that’s too steep, consider the “McAfee Premium Family” subscription, which costs $69.99 for the first year but does not include identity theft protection. McAfee also offers a 30-day money-back guarantee on all its plans.

7. Bitdefender Antivirus - The Best Lightweight Antivirus Software
View Plans Links to Bitdefender Antivirus
Product Specs
Virus Detection Yes Malware Detection Yes Firewall Yes Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring Yes
Who Bitdefender Is Best For
Bitdefender never slowed down our devices while running scans. We barely noticed Bitdefender was running in the background. It never bombarded us with pop-up notifications while we were working or playing games. The apps don’t take up a lot of space and they’re easy to use. Plus, the free plan comes with real-time protection, which is rare to see.
Pros
- Perfect score in our virus detection test
- Protects up to 25 devices
- Apps are user-friendly and very lightweight
Cons
- Offers a VPN, but as a separate app
- Prices increase after the first year
Malware Detection – Very Good
Bitdefendere has very good malware detection and protection rates. Bitdefender’s real-time protection detected and blocked every malware test file we tried to download. This isn’t surprising, considering it receives high marks on AV-TEST’s platform.
Additionally, we like that Bitdefender offers multi-layer ransomware protection to keep your files safe. It also provides web protection from malware-infected links and safeguards you from hackers with scam prevention tools.
User Experience – Excellent
Bitdefender offers protection on Windows, macOS, Android, and iOS. Depending on the subscription tier you choose, it can secure up to 25 devices. We also found its apps very simple to install and navigate. For example, it took us less than five minutes to install Bitdefender’s Windows app and run a quick scan.
While testing Bitdefender, we were really impressed by how lightweight its apps are. Over the course of three days, we continuously had Bitdefender running full scans while we used our devices to surf websites, hold video calls, play online games, and stream movies. We never noticed any performance issues.
Price – Excellent
Bitdefender subscriptions come in tiers. We believe the “Bitdefender Antivirus Plus” option is perfect for anyone just interested in antivirus protection. We recommend the three-device plan, priced at only $29.99 for the first year. You can try it free for 30 days. Bitdefender also offers a 30-day money-back guarantee.
Bitdefender is also one of the best free antivirus services in 2025. Unlike most other free antiviruses, Bitdefender includes real-time protection so you don’t have to remember to scan your device frequently.
Methodology: What We Test When We Review Antiviruses
We want to make sure we only recommend excellent antiviruses, so we spent three months testing 20 popular antivirus services. During our time testing these services, we compared them based on key metrics, including:
- Malware detection rates: We used multiple malware test files (including the EICAR file) to assess each antivirus program’s detection rate. We also referenced third-party antivirus tests from reputable agencies (like AV-TEST).
- Performance: We checked how each antivirus impacted our test devices during scans, focusing on noticeable slowdowns, system freezes, or app crashes.
- Ease of use: We evaluated how easy it is to install and use each antivirus service. We prioritized antivirus services that provide protection across multiple operating systems.
- Extra security services: Most good antiviruses include additional security tools. All our top picks offer a VPN, and most include a password manager or identity theft protection in their bundles.
- Overall price: Antiviruses usually offer multiple subscription tiers. We analyzed each antivirus service’s pricing to ensure it is affordable and covers a decent number of devices. We also checked antiviruses that offer a free version, a free trial, or a generous money-back guarantee.
Recap
Getting antivirus software is the first step towards personal digital security and online safety. We highly recommend antivirus protection from Norton, Aura, TotalAV, Guardio, Surfshark, Norton, McAfee, and Bitdefender — each for different reasons. That’s why we’re sure one of these seven offers the ideal solution for your device protection needs.
It’s important to point out that antivirus software isn’t the only digital security measure out there. Many of these antivirus plans have add-ons that result in more comprehensive protection like identity theft protection and a VPN.
