There are currently dozens of antivirus tools available on the market. Big-name options such as Norton, McAfee, and Bitdefender typically get the most headlines and the most attention. But are the top-branded tools on the market truly the best?
Unfortunately, parsing through the many different lab tests, consumer reviews, and other data can be time-consuming. Even more so, comparing each available service against the other ones is not a simple task.
Thankfully, we’ve taken on a large bit of the hard work for you! Using currently available data from recent independent testing labs, pricing data, and consumer review site scores, we’ve developed simple tools that will help you quickly and easily compare over available 50 antivirus tools.
Our tools offer a completely unbiased approach to finding the best antivirus software for the price. This way, you know you’re not getting sold a product that could be ineffective at finding and removing malware from your system.
Consumer-friendly table of antivirus software
If you’re looking for a quick and easy reference guide, use this table to look up the software you may be interested in purchasing, or to compare different software based on certain, important criteria, such as price.
Aggregated antivirus scores and data
Use the following tool to compare antivirus tools based on protection (how effectively they identify malware), performance (how efficiently they run on your computer), and false positives (how often they incorrectly identify safe programs as viruses). You can also filter for price, and by how many device installations you’ll get for the lowest price possible.
How to use this tool
There are multiple ways you can use this tool.
First, you can filter by aggregated protection, performance, or false positive scores. Simply click the box for that name.
Each tool is organized based on how many independent labs have a recent test for that software.
All software available in the data is colored by the aggregated scores they received (0-100, with 100 being a perfect score). Each point in the chart is sized by how many device installs you get for the minimum purchase price.
Use the filters on the right side look up specific tools by name, or to filter based on the minimum number of devices with 1-year purchase, annual subscription price (if any), the number of independent labs testing each program, and by the average score for that category.
Do I need antivirus software?
If you own a personal or work computer or any other device that connects to the internet, you need antivirus.
Bad actors online are regularly using and improving their methods to infect computers. That includes through phishing emails and websites, infected downloads (including through popular social media sites like Facebook), and even from USB devices, such as flash drives.
According to G-Data, a new malware variant is detected online every 4.2 seconds. There were nearly 8 million known computer viruses in 2017, as well.
The longer you have a computer and the more websites you access and emails you receive, the greater your chances of getting a virus infection. With millions of viruses floating around the web, it ultimately becomes a question of not if you’ll get a computer virus, but when you’ll get one.
Computer infections cannot only cripple your work and be costly to remove, but they can also steal valuable data. And many viruses are designed to hide on your computer, quietly recording your keystrokes, passwords, and more. Alternatively, ransomware, which is designed to lock you out of your computer and demands payment to be removed, is among the fastest-growing types of malware.
All operating systems are vulnerable to virus infections
All computer users should consider installing at least a free, third-party antivirus tool. At present, most operating systems come with a free tool pre-installed, but you should also consider purchasing or downloading a separate application. Our data suggest that the programs included in most operating systems are not nearly as effective.
The single best solution to stopping a malware infection is to use an antivirus program. These tools continuously scan your computer or mobile device and your web browser, looking for known viruses and anything that looks and acts like a virus. When a suspected virus is detected, the tool will automatically quarantine it, preventing it from infecting your device. You will then get a message that gives you the option to either delete the file if it’s a virus or release it if it was a false positive.
If you’re installing an antivirus tool on a device that’s already infected, you can also use the tool to scan the device and remove any pre-existing malware or other infections.
Although Mac users should also consider getting an antivirus tool, Windows users, in particular, have the greatest need. Over 99 percent of malware that exists were specifically designed to infect Windows computers.
This does not mean that Windows computers are inherently more vulnerable than Mac computers. However, the prevalence of viruses impacting Windows computers means that as a Windows user, you are simply more likely to run into a virus at some point while browsing the web or using your email.
One of the biggest threats for Mac users is complacency. Although most viruses that exist were designed for Windows computers, Mac computers are still susceptible to getting virus infections.
Notably, there are far fewer antivirus programs that exist for Mac computers, mostly because of the far lower number of Mac computers and fewer number of viruses impacting Mac computers. As a result, our research only focuses on Windows computers. Still, you can find a review of top Mac antivirus programs here.
There’s an on-going debate in the Linux community about whether or not antivirus is necessary for this operating system. The argument is essentially the same as with Mac users. Because there are fewer Linux users, there are also far fewer viruses attacking Linux operating systems.
However, we’ve found that Linux computers can and do get viruses. You can find out more here in our study on Linux viruses.
Android and iOS antivirus
Viruses on mobile devices are far less common, but they do exist. Among the mobile device world, the situation is similar to Windows vs. Mac. If you have an Android device, you are extremely susceptible to getting a virus infection, especially from malicious app downloads.
According to mobile cybersecurity company Lookout, phishing is among the biggest threats facing mobile users. Importantly, many mobile users are not prepared to stop phishing attempts, which increasingly come in the form of spam text messages.
Many of the antivirus tools we cover in our data provide mobile tools. However, there are also many tools available specifically for Android and iOS devices.
How to Pick An Antivirus Program
Using independent antivirus lab tests, we’ve gathered data on over 30 AV tools currently available to consumers and business. We then created a tool which compares each tool based on its average lab test results across the three major categories tested:
- Protection: How effectively each tool identifies and stops malware
- False Positives: How often each tool incorrectly labels safe programs as malware
- Performance: The overall impact each tool has on system resources (such as memory and CPU usage)
There were 5 testing labs’ data used in our analysis:
- SE Labs
- Virus Bulletin
- MRG Effitas
Each lab maintains different rating standards and methods. For example, AV-Test creates a score out of 6 for each category. Meanwhile, AV-Comparatives assigns a score out of 100 for Protection, but uses the raw number of False Positives instead of creating a score.
Additionally, not every lab tested all of the same AV tools, and some, like MRG Effitas, did not test for all three categories (MRG Effitas only offers Protection results).
To account for these differences, we took averages and made adjustments to equalize their ratings. We also created our charts to differentiate by how many lab tests each AV software appeared in.
Furthermore, we added extra filters to help consumers identify which tools might be the best value. For that, we included a minimum purchase price, the number of devices allowed for the purchase, and an average score based on other consumer review sites, where available.
A Note on Avast and AVG
While Avast performed extremely well in our review, this service now comes with a warning. A Motherboard and PCMag investigation published in January 2020 found that Avast was not only secretly recording and collecting user web browsing data, but was then selling that data for profit. According to the report, Avast was recording “Every search. Every click. Every buy. On every site”. The company was then selling that data to major companies, including Google and Microsoft.
The data was sent to and processed by Avast-owned company Jumpstart, which marketed and sold the data. Since the report published, Avast killed its Jumpstart subsidiary company, but the damage had already been done.
Note that Avast also owns AVG, making this well-rated antivirus program suspect as well.
Outside of these concerns, both Avast and AVG are well-performing antivirus tools. However, consumers who have extra concerns may want to avoid these tools in favor of other equivalently-rated programs.
There are a few interesting takeaways from the data that may interest consumers.
First, it should be noted that almost every AV tool on the market that was tested by the 5 testing labs performed similarly with regard to Protection. That means that almost any tool you purchase is likely going to identify, quarantine, and clean malware from your system with a high degree of success. Of the tools tested by the labs, only 4 received sub-par scores:
- ViriT eXplorer PRO: 40.83/100
- Webroot Antivirus: 72.75/100
- Rising Security Cloud Client: 77.86/100
- Quick Heal Total Security: 79.40
All others received aggregated scores of 90/100 or better. This means consumers’ best option is to consider more carefully the other areas of value: Performance, False Positives, Price, and the number of devices allowed per purchase.
Only two testing labs (AV-Test, AV-Comparatives) measured the AV tools they tested for system impact. Of those tested, the top 3 tools were:
- eScan Internet Security Suite
- Ahnlab V3 Internet Security
- Panda Free Antivirus
Ahnlab is not available to consumers, however, and while Panda Free Antivirus scored well in performance, its false positives score was extremely subpar. That makes eScan Internet Security Suite the best in this category.
Four testing labs used False Positives as a measure for testing. Not every tool showed up in every lab test, however, and we had to make some adjustments particularly for AV-Comparatives, which did not create an average score for that category but instead offered only gave a raw number (e.g., the total number of false positives each tool sent back).
25 tools in this category scored a perfect 100, meaning they did not send back any false positives. However, when you consider the Performance and Protection scores, the top tools in this category are:
- eScan Internet Security
- Vipre Advanced Security
eScan comes out on top in this category as well, although Vipre performed noticeably better in the Protection category, whereas eScan scored a perfect 100 Performance and False Positives.
Quite obviously, most consumers prefer a free tool versus a paid one. And indeed, many of the free tools on the market are high-quality options worth considering.
The best free antivirus tools on the market, based on score averages across all three categories, include:
- Tencent PC Manager
- Avira Free Security Suite
Consumers may also want to consider using Microsoft Windows Defender, which comes loaded with any new installation of Windows, or Panda Antivirus Free. Those two tools score well in the Protection and Performance categories, but poorly in False Positives.
As far as low-cost options, however, there are a few stand-out AV tools that may offer great value and quality, while there are some notable exceptions that are far too pricey for what they deliver.
Among the paid tools, the best include:
- NANO Antivirus: $12.03 for 500 days (may not be available to US or UK consumers)
- Arcabit Antivirus: $23.64/year
- Avira Antivirus Pro: $35.99/year
- G-Data Internet Security: $39.95/year
- Comodo Internet Security: $39.99/year
- eScan Internet Security: $49.95/year
Beyond these, most services cost $50/year or more, and indeed, the services with the best test results are also ultimately among the most expensive. eScan is the only exception, making it one of the best-paid options based on its positive test results.
A few tools are simply not worth the price, however, as they are both expensive and poor performing. These include:
- Quick Heal Total Security: $74/year
- PC Pitstop: $50/year
Other available tools may still be worth the price when consumers take into consideration other features. Individual investigation of those features may be prudent before making a final decision based on price.
Minimum devices per purchase
Most AV companies charge more money per month for more device installations. However, each offer a certain number of device installations for the base price. In most cases, you can install the software on multiple devices for one the cost. If you need to cover multiple devices while saving money, two AV tools are standout options:
- McAfee Internet Security: 10 devices, $89.99/year
- Total Defense Premium: 5 devices, $79.99/year
Those looking to cover multiple devices may be better served with one of these options, all of which have good test results as well.
