This ultimate comparison was compiled based on the research of our seasoned experts and the top independent labs in the world so that you could make an informed decision.

We follow the work of four labs that regularly release detailed reports: AV-Test Institute based in Germany, MRG-Effitas, and SE Labs found in the UK as well as AV-Comparatives based in Austria.

AV-Test independent IT security institute in Germany says that the total number of registered malware has grown from 65 million to over 1 billion in the last nine years. In the last year alone, they discovered more than 100 million new viruses and malicious programs.

One of the fastest growing trends is ransomware. These attacks can be extremely costly. For example, an attack involving the NotPetya ransomware cost shipping firm Maersk more than $200 million.

As you can see, high-grade protection is more critical than ever before.

In this head-to-head battle, you’ll see the security products, features, and tools both companies offer. We look at how they stack up against each other regarding malware protection, system performance, user interface, cost, and more.

Here are the most important factors that we’ve compared:

  • Protection
  • Performance
  • Usability
  • Features
  • Pricing

You need to be able to protect yourself against any digital threats, so you don’t have to deal with these kinds of problems ever in your life.

So let’s see which competitor does it better.

A quick overview of the results

If you’re not too keen on all the nerdy stats or just in a bit of a rush, we have compiled a handy summary of the results.

  • Protection

  • Performance

    Both software showed less than average and also some better than average results in different tests.

  • Usability

    Both products offer easy to use user interfaces. Both also had some issues with false reporting. Bitdefender's results were still a lot better.

  • Features

    Webroot and Bitdefender offer anti-malware and VPN features, but the list is longer for Bitdefender. Including some performance enhancers, for example.

  • Pricing

Detailed results

If our short overview didn’t cut it and you need some information to make a decision, we have a lot more to offer. Let’s dive into the details and see all the test results. We put Webroot and Bitdefender head-to-head in all the categories using data gathered by our experts and test results of top independent testing facilities.

So let’s dig in.


Protection is absolutely the most crucial part of any antivirus software. After all, it is the reason why you’d want to have it on your computer. In the last tests run by independent test facilities, one of the competitors performed a lot better than the other.

Usually we’d like to use information from at least two labs, but the only lab that tests both Webroot and Bitdefender is AV-Test. Let’s check the results.

In the last tests, AV-Test put Webroot up against 307 samples of 0-day malware attacks and 2428 samples of widespread malware during a four week period. Bitdefender was put up against 402 samples of 0-day malware attacks and 20606 samples of malware during the same period.

Webroot showed quite a lousy result protecting only against 66.5% of threats. Bitdefender, on the other hand, defended the computer like a hero, achieving a full 100%.

Webroot performed a lot better in detection tests with a 98,9% result. It still isn’t anything to brag about as it’s a result below the industry average. Bitdefender, once again, showed a perfect 100% score.

Protection against 0-day malware attacks, inclusive of web and email threats

307/402 samples used

2428/20606 samples used


These results make it easy to call Bitdefender the winner of this category. If you’re looking for good security, you should definitely opt for Bitdefender.

Winner: Bitdefender


If keeping your computer comes with the price of it slowing down, the trouble isn’t worth it. That is why antivirus software’s performance is another crucial aspect to keep in mind when choosing which one to buy.

In some cases, browsing everyday websites and opening standard files can be a real problem. This is why we put the competitors head-to-head to see which one is faster. Let’s see the results so you could avoid any issues.

AV-Test lab research shows that Webroot performed a little slower than the industry average in a few of the tests. It may cause some problems when downloading or installing applications.

The performance of Bitdefender was better when installing applications, but a lot worse when launching websites or copying files.

12 test cases applied

Slower installation of frequently-used applications

19 installed applications

Slower copying of files (locally and in a network)

7388 files copied


As you can see both software have their problems, as well as upsides.

Winner: It’s a tie


The usability of any antivirus software can be measured in two aspects. The first is its interface and ease-of-use. The second is the software’s false reporting. Error notifications that start popping up each time you open a perfectly virus-free photo or document prevent you from doing anything useful on a computer.

First, let’s compare the interfaces.

Webroot creates a strong presence with dark green colors. The 3D effects of buttons and patches make the design seem a bit outdated. Still, the layout is intuitive, and information easy to understand.

On the top left part of the application window, you can see the status of your computer. A scanning option is available as well. In addition, you can see when the last scan was done and when the next is scheduled.

The right side of the window consists of information about used features. You can see which features are turned on and which are not, as well as other settings. For PC Security, there is a button for Realtime Shield, Web Shield, and Firewall.

If you click on Identity Protection, Utilities, or My Account, you can see further details in each section. For advanced settings, look up in the right corner of the window.

Webroot User Interface

Bitdefender offers a modern and easy to understand application with an intuitive design. Compared to some of the competitors, it has a bit more information on the home screen. Still, the important things stand out, and everything can be found in a heartbeat.

On the left side of the window, you can find a menu for different modules.

The first is the dashboard that is basically the home screen and gives you an overview of everything that is going on. There’s a big status message on the top, letting you know if your computer is safe. You can also start a quick scan there, open the VPN, safepay, and add other devices you wish to keep safe. There’s also an option to add a customized quick action.

If you check back to the right, you’ll find the protection module, where you can see if your device is protected and if the program is up to date. You are also able to start a quick scan or a vulnerability scan from there.

If you go through the options on the left, you are presented with privacy, utilities, notifications, your account, setting, and support.

Now let’s dive into false reporting.

During their tests, AV-Test laboratories also gather information on false reporting. The results show that Webroot had some serious trouble; in many cases, it thought that legitimate software was malware.

It can cause problems for people who are not too familiar with computer programs and just delete everything the antivirus detects as malicious. It may mean that essential applications and all their data get deleted during system scans.

Only 2 false reports showed up with Bitdefender, while Webroot had some serious problems.

Industry average Webroot Bitdefender
False warnings or blockages when visiting websites

500 samples used

False detections of legimate software as malware during a system scan

1 515 716 samples used

False warnings concerning certain actions carried out whilst installing and using legitimate software

40 samples used

False blockages of certain actions carried out whilst installing and using legitimate software

40 samples used


As you can see, both contenders have a simple to use interface. Both products had some issues with false reporting, but Webroot’s results were one of the worst we’ve seen.

Winner: Bitdefender


Webroot and Bitdefender both offer a variety of security features to protect your digital life. But Bitdefender has a bit longer list of available options.

But first, let’s see what Webroot has to offer.

Webroot’s entry-level security product is called simply Webroot AntiVirus, and it is available for PCs and Macs. There are two options available – for one device and up to 3 devices. It prides itself in fast scan times and maintaining a small endpoint agent that takes up only 15 MB of drive space.

The king of the lineup is Webroot Internet Security Complete, and it is available for 5 PCs, Macs, tablets, or smartphones.

The only thing the Mac version offers, that the PC version doesn’t, is the additional Time Machine protection for your backed-up files in case of a ransomware attack. If you compare the two products the other way, you can see that PC users get a lot more than the Mac users.

Here’s a list of all the features that are only available with the PC version:

  • Advanced Threat Defense that uses a technique called behavioral detection to closely monitor active apps. The moment it detects anything suspicious, it takes instant action to prevent infections.
  • A new cyber threat intelligence network threat prevention technologies that can analyze and identify suspicious network-level activities and block sophisticated exploits, malware, or botnet-related URLs, as well as brute force attacks.
  • Advanced aunty fraud filtering system warns you whenever you visit websites that may try to scam you.
  • Safe Files that can prevent unauthorized changes to your most important files. You can simply add folders to the watch list, and Bitdefender guards the files stored in them against ransomware and other types of malware. Only applications you explicitly trust are allowed to access your Safe Files.

These examples are only from the protection features. Bitdefender also offers performance features such as Global Protective Network, Battery Mode, as well as Game, Movie & Work Modes for PC. There is also safe online banking, WiFi security advisor, social network protection, vulnerability assessment, a Password manager, and a file shredder features available to PC users.

Winner: Bitdefender


Price plays an important role when deciding which option to go with. You have to take all the details into account to make the best decision that is best for you.

When investing in antivirus software, you are not purchasing an application but rather an ease-of-mind that your digital life is in safe hands.

So let’s compare the price points that offer you that peace. Here are the prices of both Webroot and Bitdefender products.

Webroot offers its products independently, depending on the time of purchase, you may get some discounts if you add multiple products to your cart.
