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.

Who TotalAV Is Best For
TotalAV got high marks in all the malware tests we ran. We ranked TotalAV highly for its excellent malware detection. It scored well in our malware detection tests, and results from well-known antivirus tests by independent security firms also backed up our findings. That’s why we recommend TotalAV for users seeking top-tier malware detection and 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 excellent cross-platform compatibility, with apps for Windows, macOS, Android, and iOS. We installed the service on all of our devices, and the installation process was very straightforward. We also like that the TotalAV apps are lightweight — we didn’t notice any significant slowdowns 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.
TotalAV also offers a 30-day refund for all long-term purchases. It has a free version too, but it’s pretty limited — especially since it lacks real-time protection. This means you’d need to regularly perform manual scans to make sure your device stays safe.

2. Surfshark Antivirus - The Best Antivirus For All-Around Digital Security

Who Surfshark Antivirus Is Best For
Surfshark Antivirus offers great malware protection, and it’s also bundled with other digital security services.
We think Surfshark Antivirus is excellent for overall digital security because it comes bundled with many other useful security tools, including a top-rated VPN, a data breach monitoring tool, and a data removal service. That’s why we recommend it to users looking for an all-in-one digital security 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
In addition to blocking our attempts to download the EICAR malware test file, Surfshark’s antivirus also stopped us from accessing unsafe links and websites as part of its CleanWeb feature. We also ran manual scans after hiding malware test files all around our Windows laptop, and Surfshark detected 90% of them. The one it didn’t find was hidden in a compressed .zip folder.
While we’re happy with Surfshark’s malware detection and protection, it currently lacks the extra protections that TotalAV offers. Ransomware protection is one example.
Expert Tip: One way you can protect yourself from ransomware by regularly backing up your most important files. We suggest using an encrypted cloud service for this. That way, if you ever get locked out of your computer, you’ll have a copy of your important files.
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, too, with tabs along the left margin dedicated to each service (see our screenshot above).
Unfortunately, we had to dock some points since the iOS and iPadOS apps don’t have any antivirus features. Also, unlike TotalAV, it doesn’t include access to device optimization tools on any platform.
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.

3. Norton Antivirus - The Best Cross-Platform Antivirus Software

Virus Detection Yes Malware Detection Yes Firewall Yes Full, quick, and scheduled scans Yes Real-time protection Yes Behavior-based monitoring Yes
Who Norton 360 Is Best For
Norton 360 works across multiple platforms, and also has feature-rich apps. Norton 360 offers excellent cross-platform support and a really good user experience. That’s why we think this antivirus is a good option for anyone interested in securing more than five devices — as well as using an antivirus on different 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 will more than double after the first year
- The password manager is a separate app
- Offers device optimization, but as a separate service
Malware Detection – Excellent
Norton 360 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 360 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. We like how Norton 360 offers protection for all devices: Windows, macOS, Android, and iOS. What’s more, it can protect up to 10 devices with its highest-tier subscription, making it a strong pick for users with multiple devices.
Norton 360’s apps are also user-friendly. Whether you’re on desktop or mobile, it’s easy to navigate the interface. Plus, there are helpful explanations for all settings and features, so you won’t feel lost while using it.
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.
Norton 360 doesn’t offer a free version, but it does include a free 14-day trial. All plans are backed by a generous 60-day money-back guarantee.

4. McAfee Antivirus - The Best Antivirus for Families

Who McAfee Is Best For
McAfee offers great plans for families, and is also simple to use. We ranked McAfee as the best option for families because its subscriptions are specially tailored to families. These plans let you secure an unlimited number of devices and offer protection for up to six family members.
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 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.

5. Bitdefender Antivirus - The Best Lightweight Antivirus Software

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. In our tests, we noticed that Bitdefender has very lightweight apps — the complete opposite of McAfee. We recommend getting Bitdefender if you want an antivirus that runs silently in the background without interrupting your activities like browsing the web, gaming, or streaming.
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 Bitedender 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.
Bitdefender also has a free version, which we consider one of the best free antivirus services in 2025. Unlike most free antiviruses, Bitdefender’s free version offers real-time protection. On top of that, Bitdefender also comes with a free 30-day trial and a 30-day money-back guarantee.
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. We also compared them to see which ones provide the best value. We compared them based on the following metrics:
- 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 staying safe in the digital world. With the right software, you’ll worry less about cyber threats. But antivirus software is not the only digital security measure you can take. Once you get it set up, be sure to check our review of the best identity theft protection products.
