Avast One offers two plans: one for up to five devices and one for up to 30. The larger plan is ideal for families or small businesses with up to around 10 employees. Avast One works for Windows and Mac computers and iOS and Android smartphones. It’s very easy to use across all these devices.

What Avast Offers

Avast offers a wide range of tools. Proactive security tools include a file shield that scans files for malware before opening them, a password manager, and a firewall. Ongoing monitoring tools include a powerful antivirus scanner. Privacy tools include a VPN, secure browser, and webcam protection. Device optimization tools include a disk cleaner and driver updater.

Here’s the full list of the features Avast offers:

  • Password manager inside secure web browser

  • Customizable firewall

  • Highly reliable antivirus scanner

  • VPN with 55 locations

  • Webcam protection

  • Disk cleaner and optimization tool


Let’s take a closer look at some of the key security tools that Avast One offers.

Antivirus Scanner

Avast’s antivirus scanner enables you to identify and eliminate malware on your system. You can run a quick or deep scan, or choose specific folders to scan. It also comes with a customizable firewall that you can use to stop malware from infecting your computer.


The VPN included with Avast One offers access to 55 server locations around the world. It’s speedy and includes DNS leak protection, which prevents information about your device from being exposed while you browse the internet.

Secure Web Browser

Avast One includes a secure web browser that prevents advertisers from tracking you with cookies. It can also automatically hide sensitive information, such as payment details, when you shop online.

Password Manager

Avast’s password manager is an extension for the secure web browser. It can help you create hard-to-guess passwords and warn you if you create duplicate passwords. Avast also alerts you if any of your passwords are leaked through large-scale data breaches.

Disk Cleaner

Avast can identify junk, temporary, and old files on your computer and help you remove them. It can also ensure that your drivers and software are up to date.

Ease of Use

I found Avast One to be very easy to use. After downloading it from the Avast website, it installs in minutes. Setting it up on your device is simple.

All the tools available in this cybersecurity suite can be found in a single interface and are organized into groups for Device Protection, Online Privacy, and Smooth Performance. You can run scans and customize settings within this interface without opening new windows.

If you use the free version of Avast One, premium tools are indicated with a lock icon. I found that the software does occasionally launch pop-ups encouraging you to upgrade, which can be a little annoying.

Detection Rates and Reliability

Avast’s antivirus scanner has been tested by the independent antivirus testing firm AV-Test. In those tests, Avast detected all planted malware on Windows and Mac computers. The antivirus software received the maximum possible scores for protection, performance, and usability.

In my own testing on a Windows computer, Avast didn’t detect any malware, but it did find more than 20GB worth of old files to clean up. A basic scan only took around 30 seconds to run.


Avast One has two plans available depending on how many devices you need to protect. There’s also a free plan, although this severely reduces the depth of antivirus scans and limits your access to privacy and optimization tools. You can also purchase Avast’s antivirus scanner on its own through the Avast Premium Security plan.

Avast One offers a 50% discount for the first year and comes with a 30-day money-back guarantee.

Value for Money

I think Avast One offers excellent value for money. You get not only antivirus software, but also a wide range of tools that can protect your information online and prevent your devices from being infected with malware in the first place. All of that costs just $99.99 per year for up to five devices, which is less than most standalone antivirus software. 

Families and small businesses can protect up to 30 devices for $139.99 per year. That comes out to just $0.39 per device per month for comprehensive cybersecurity protection.

Help and Support

Avast offers 24/7 customer support by phone and through an online form. I got in touch by phone and was able to speak with a very helpful technician right away.

Avast’s website also has a very detailed online knowledgebase. The tutorials include detailed screenshots to walk you through how to protect your devices.

Bottom Line

Avast One is a comprehensive and easy-to-use cybersecurity suite. It offers a wide range of tools to protect all your devices. You get a top-rated antivirus scanner, a VPN, a secure browser with a password manager, a disk cleaner, and more.

You can use Avast One for free, but the paid version of this suite offers the most protection. It’s very affordable for either five or 30 devices, making it a great choice for families and small businesses. Overall, I’d recommend Avast One for almost anyone who wants to stay safe from digital threats.
