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. This number was more significant than the grand total in 2012.

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.

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 Avast 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.

Let’s compare the test results of two labs, AV-Test and SE Labs, so that you can see for yourself.

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. Avast 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. Avast, 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. Avast, once again, showed a perfect 100% score

SE Labs use a bit of a different testing method. It conducts tests and gives each product a protection score based on the overall level of protection, making no distinction between neutralized and blocked incidents.For each product, they add blocked and neutralized cases together to create a straightforward tally. Avast scored 98 out of 100. Webroot scored a little less, 96 out of 100.

SE Labs didn’t discover that much of a difference between the software, but you can still see that Webroot came in second. This one is easy to call.

Winner: Avast


If keeping your computer safe, 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.

Industry average Webroot Avast
Slowing-down when launcing popular websites

50 websites visited

Slower download of frequently-used applications

20 downloaded files

Slower launch of standard software

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

Avast has a modern and simple design, a bit darker just like the other contender. The interface is intuitive and lets you find the most important functions with ease.

The default layout is configured to suit most users. However, you can manually set your preferences in the Settings.

The most critical information is always there and lets you know if your computer is protected or not. There is a big circle with a tick to indicate that. You can also start a smart scan with just one click.

In addition to the status, you’ll find the information about protection, privacy and performance, on the left bar of the window.

Notifications and preferences can be found on the top right corner.

Avast User Interface

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. Avast on the other hand, did really good.

False warnings or blockages when visiting websites

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. Regarding false reporting Webroot’s result were subpar to say at least.

Winner: Avast


Webroot and Avast both offer a variety of security features to protect your digital life. But Avast has a bit longer list of available options. That said, it also requires you to pay extra for a lot of advanced 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 mid-tier option is called Webroot Internet Security Plus, and it adds Identity Theft Protection to the list of features. It secures your usernames, account numbers, and other personal information against keyloggers, spyware, and other online threats targeting valuable personal data.

Internet Security Plus also lets you browse securely with real-time anti-phishing software. Whether you have a built-in webcam or an accessory, the software offers to safeguard against threats like Trojan malware hijacking it.

This option is available for 3 to 5 devices and works on tablets and smartphones as well. Although iOS device protection consists only of a secure browser, backup, and password management. It does not scan iOS apps to block malware.

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

The only thing that differs it from the last option is it’s 25 GB of cloud storage.

As the proliferation of online gaming retailers and in-game microtransactions opens up gamers to even more cyber threats, Webroot also has a specialized option made for gamers. Webroot AntiVirus for Gamers is designed to increase drive space, reduce access times, and improve gaming performance.

They even offer a performance guarantee. If you’re not convinced it protects without impacting gameplay, they’ll refund your purchase price within 70 days.

This option sadly only works with PCs.

The last addition to its lineup was Webroot WiFi Security that offers VPN protection for 3 to 5 Windows, Mac, Android, or iOS devices.

It maintains the online safety of your whole family at home and on public internet connections. You can feel secure and private work, share, bank, and browse.

Now let’s take a look at what Avast has to offer.

Avast product line consists of three different categories – Security, Privacy, and Performance. From the security part, you can find two options.

Avast Free Security is the most basic antivirus bundle you can get.

It offers you Anti-Malware Security that blocks viruses, spyware, Trojans, and other malware, and scans your computer for already-hidden threats.

Web & Email Shields alert you of unsafe websites, blocks insecure downloads, stops dangerous email attachments, and prevent intrusive web tracking.

Wi-Fi Security Scan checks your entire network and all connected devices for vulnerabilities to help you stop hackers from stealing your personal data.

But for the everyday user, ongoing protection is much needed. For that, you have to opt for the Avast Premium Security option.

With the premium product, real-time Wi-Fi security alerts feature is added so you can instantly be alerted to network weaknesses and intruders.

Also, one of the essential features today is ransomware detection, as this is the fastest-growing segment in malware. Ransomware attacks in the US alone cost an estimated $7.5 billion in 2019. Avast Premium Security offers a Ransomware Shield to protect your files.

The premium product comes with two purchase options. The first lets you use only one PC, and the other is for up to 10 devices, but you can use it on Windows, macOS, Android, and iOS platforms.

Avast also offers Avast SecureLine VPN for some extra. This product lets you keep everything you do online totally private thanks to the bank-grade encryption. You can browse, bank, message, and shop without having to worry about hackers or anyone else seeing what you do online or stealing your data.

Another extra is its Avast AntiTrack that helps you online. It lets you know when you’re being tracked, keeps your true identity private, stops targeted advertising, and erases your browsing history automatically. For some more money, you can find a Secure Browser in Avast lineup as well. Password protection is another add-on the company offers.

On the Performance segment, Avast offers three products. Avast Cleanup Premium lets you boost your computer’s speed and performance. The last two options are available for windows only. Avast Driver Updater keeps your drivers up to date with a single click, and Avast Battery Saver maximizes your laptop’s battery life.

For the best all-round protection you must opt for Avast Ultimate. This is Avast’s all-inclusive bundle where you get everything we have mentioned before.

Both companies offer the products needed for using your computer safely, offline, and online. Still, Avast has a bit longer list of options to go with.

Winner: Avast


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 Avast 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. For the best all-around protection, it’s better to go with a complete package. If you go with only one pick, it may mean that some parts of your digital life may go unprotected.
