Webroot and Avast are two of the most famous antiviruses. They’re also exceedingly effective at neutralizing security threats according to multiple lab tests. There might be minor differences in how they operate, but you’ll stay protected from online threats whether you choose Webroot or Avast.

So, why does it matter which security software you choose?  First, the two antiviruses solve security threats differently. That affects their speed of dealing with threats. It also affects the antivirus file sizes. On the other hand, there’s the issue of pricing, the number of devices covered, and other add-ons.

If you’ve been looking for a security solution and you can’t choose between Webroot and Avast, here’s a guide to help you make a buying decision.

Compatible Devices

Both Webroot and Avast can be installed on Windows computers, Mac devices, iOS, or Android mobile gadgets. Webroot features a lighter installer, though. Sized at less than 4MB, the software consumes very little space on your machine.

Avast is larger and could take a few minutes to install and setup, but it features a lot more features. Avast also comes with a wide range of varieties so that you could choose Avast for business, the free program, or the regular security tier.

What’s covered?

Both Webroot and Avast begin scanning your computer for security threats immediately you launch them. Surprisingly, the two companies share a lot in the kinds of threats they neutralize. Below are some of them:

  • Real-time virus threats
  • External drive threats
  • Spyware
  • Worms and Trojans
  • Phishing and rootkit threats
  • Adware and game-time threats

Webroot lacks anti-spam protection and doesn’t offer VPN protection. But as explained in this Webroot vs. Avast comparison guide, it might be the best choice in the end. 

When you compare the prices of both solutions; for example, Webroot offers better value for your money.

Webroot vs. Avast Pricing

Webroot costs $29.99 for an annual license on one PC or Mac computer. For an extra $7, Webroot allows you to install its security solution on three devices. By comparison, Avast charges $59 for a single device yearly license and $79.99 for multiple devices.

Although Avast offers several more features than Webroot, it charges you double the cost of its competitor. You could argue Avast is not the most expensive antivirus available. Indeed, more popular antiviruses like McAfee cost over $50, but they almost always offer protection for an unlimited number of devices.

That said, you should decide what you want more. On the one hand, Avast offers a lot of minor add-ons you may or may not need, but it’s costly. On the other, Webroot lacks the bells and whistles of Avast, but it is costs-saving.

Web Interface and ease of use

The Avast web interface looks the same whether you install the free version or its premium plan. It features a navy-blue background color with some dashes of purple and green in some areas. It’s a simple interface, and you can quickly navigate throughout the site with no challenges.

On the main interface, there’s an icon that reads “run a smart scan.” Clocking it initiates a relatively comprehensive scan on your PC.

Webroot, on the other hand, looks less organized and its colors are not the flashiest. It also features a lot of information on the home page. But unless you have problems with digesting too many details in one place, it’s easy to navigate.

Despite the web interface, Webroot does its jobs, and that’s what should matter. It also features an excellent cloud-based threat monitoring feature. It works by placing all unknown programs on watch. And if they display any unwanted behaviors, the antivirus eliminates them.

Performance in Lab Tests

Every antivirus company claims it can eliminate a wide range of security threats. But whenever they’re tasked to eliminate threats in a lab, most antiviruses perform poorly.

When both Webroot and Avast were put on a test to eliminate malware by PCMag security experts, Webroot emerged the winner. Typically, the antiviruses are loaded with a host of security threats and activated to neutralize them.

With Webroot, its software performs a series of deep scans until all threats are eliminated. It has the advantage of completing comprehensive scans in less than ten minutes; something standard antiviruses finish after an hour.

Obviously, Avast didn’t perform poorly. The antivirus eliminated about 90% of all threats on any computer. But that ranks it lower than Webroot and most tier solutions like Kaspersky, Norton, MacAfee, and Cylance.

When it comes to detecting phishing scams, though, Avast performs slightly better than Webroot. It has eliminated 98% of phishing issues before, one point above its rival Webroot.  It’s also more effective in identifying unwanted URLs but lags when it comes to identifying ransomware threats.


Avast wasn’t always an expensive security solution. But in a bid to gain attention and improve its brand to the level of a security suite, the company introduced several added features. First, it now features anti-spam protection, something you won’t find in many of its peers.

The company then improved its ransomware protection so that threats can’t modify your files in any way. It also added a sandbox features to help you judge which suspicious files you should delete and which ones you can keep. There’s also the VPN protection feature. And together with all the other add-ons mentioned above came at the expense of a higher cost.

Surprisingly, Avast doesn’t offer live communication as a customer support feature despite its high cost. By comparison, that’s a service you get from Webroot and all other top tier providers. It also features a shorter money-back guarantee offer at 30 days versus Webroot’s 75 days.

To Conclude

Webroot and Avast are two of the most popular antiviruses on the Internet. Avast is fairly more popular thanks to its free program and frequent marketing campaigns. But when the two security solutions are compared, there’s little to differentiate them in performance.

Despite that, Avast is more expensive than Webroot. Sure, it features several extra features. But if you’re looking for an antivirus in the traditional sense, you’ll get more value by purchasing Webroot.
