Viruses and malware are no longer the only threats internet users need to worry about. Phishing emails, fraudulent websites, scam messages, manipulated videos and attempts to access personal information have become everyday digital risks. At the same time, most people use several connected devices that all need protection.
This is where Avast Ultimate comes in. The comprehensive security package combines four premium applications: Avast Premium Security, Avast SecureLine VPN, Avast AntiTrack and Avast Cleanup Premium. It also includes modern AI-powered features designed to help detect scams, deepfakes and suspicious messages.
One of its biggest advantages is the multi-device subscription. A single license can protect up to ten devices simultaneously, including Windows PCs, Macs, Android smartphones and iPhones or iPads.
But what exactly does Avast Ultimate offer? How useful are its individual components, and how comprehensive is the protection in everyday use?
What Is Avast Ultimate and Which Features Are Included?
Avast Ultimate is an all-in-one security and privacy package from Avast. Instead of purchasing several applications separately, users get four premium products under one subscription.
The package takes a broader approach to digital security. It is designed not only to detect and block malware but also to protect privacy, reduce online tracking, help prevent scams and improve device performance.
The four main components are:
- Avast Premium Security: Antivirus protection, ransomware protection, firewall, phishing protection and AI-assisted scam detection.
- Avast SecureLine VPN: Encrypted internet connections, additional protection on public Wi-Fi networks and IP address masking.
- Avast AntiTrack: Protection against online tracking, digital fingerprint masking and alerts about tracking attempts.
- Avast Cleanup Premium: Removal of unnecessary files, storage cleanup and automated device maintenance.
The individual applications can be installed according to the operating system in use. However, not every component is available on every platform.
Avast Ultimate for 10 Devices: One Security Package for the Whole Household
One of the most important features of Avast Ultimate is its multi-device license. It allows users to protect up to ten devices simultaneously. This is particularly useful for households with several computers, smartphones and tablets.
For example, the license can cover:
- Windows desktop PCs and laptops
- Apple MacBooks and iMacs
- Android smartphones and tablets
- iPhones and iPads
The license is not limited to ten Windows computers. The ten devices can be distributed across the supported platforms, making it possible to combine different operating systems under one subscription.
Another advantage is flexibility. Users do not necessarily have to install every available application on every device. They can choose which supported Avast applications they actually need.
The device allocation can also be changed when necessary. A previously activated device can be removed from the license and replaced with another one, while the limit of ten simultaneously protected devices remains unchanged.
Which Features Are Available on Each Operating System?
| Component | Windows | macOS | Android | iOS |
|---|---|---|---|---|
| Premium Security | Yes | Yes | Yes* | Yes* |
| SecureLine VPN | Yes | Yes | Yes | Yes |
| Cleanup Premium | Yes | Yes | Yes | No |
| AntiTrack | Yes | Yes | No | No |
*Android and iOS use the respective Avast Mobile Security Premium versions. Their feature sets differ from the desktop versions.
Avast Ultimate is therefore a useful option for households with a mixture of operating systems. However, it is worth checking which specific features are available on your devices before purchasing the subscription.
Avast Premium Security: Comprehensive Protection Against Viruses, Malware and Cyberattacks
The core component of Avast Ultimate is Avast Premium Security. It protects computers and mobile devices against a wide range of digital threats and continuously monitors system activity to detect and block malware as early as possible.
Its protection features include:
- Detection and blocking of viruses and Trojans
- Protection against spyware and other malware
- Detection of ransomware and file-encrypting threats
- Protection against phishing and dangerous websites
- Scanning suspicious files and downloads
- Protection for personal data and sensitive documents
- Firewall protection against unwanted network access
Real-time protection monitors different activities on the device. Suspicious files, downloads and applications can therefore be detected before they cause damage.
Ransomware Protection for Personal Files
Ransomware is one of the most dangerous forms of malware. It encrypts personal files and demands payment in exchange for restoring access. Documents, photos, videos and other important files can all be affected.
Avast Premium Security includes dedicated protection mechanisms designed to restrict access to protected files by untrusted applications.
This is particularly useful for people who store important personal or business documents on their computers.
Firewall: Controlling Unwanted Network Access
Another important component is the enhanced firewall. It monitors network connections and helps prevent unwanted external access.
This adds another layer of security beyond traditional antivirus protection. It is particularly relevant for devices that remain connected to the internet throughout the day.
Protection Against Dangerous Websites and Phishing
Many cyberattacks do not begin with an infected file. Instead, criminals use convincing websites or fraudulent messages to trick users into revealing passwords, payment information or other personal data.
Avast detects and blocks known malicious websites and helps protect users against phishing attempts. Fraudulent messages and suspicious content are also addressed by its broader security features.
AI-Powered Protection Against Online Scams, Fraudulent Messages and Deepfakes
One particularly interesting development in Avast’s security offering is the use of artificial intelligence to identify potential scams.
The quality of fake messages, websites and videos has improved considerably in recent years. Spelling mistakes and obviously suspicious sender addresses are no longer reliable warning signs.
AI can now generate convincing messages, voices and videos that imitate real people. Even experienced internet users can be misled.
Avast Assistant: Checking Suspicious Messages and Offers
The AI-powered Avast Assistant is designed to help users assess suspicious messages, links and offers. Users can submit questionable content for analysis and receive information about potential warning signs.
This can be useful in situations such as:
- A fake parcel notification requesting an additional payment.
- An email claiming that there is a problem with a bank account.
- An online store offering a product at an unusually low price.
- A message asking users to enter login credentials through a link.
- A request for an urgent money transfer supposedly coming from someone they know.
The assistant is intended to make these situations easier to evaluate. However, it remains an additional decision-making tool rather than a replacement for common sense and careful online behaviour.
Deepfake Detection: Protection Against Manipulated Videos
Another important area is the detection of deepfake-related scams.
Deepfakes use artificial intelligence to create manipulated videos or voices that imitate real people. Such content can be used in fake giveaways, fraudulent celebrity endorsements or misleading investment offers.
Avast provides features designed to help identify deepfake scams and manipulated videos. This adds a layer of protection that is becoming increasingly relevant as AI-generated content becomes more convincing.
Protection Against Scam Text Messages and Phone Calls
Smartphones are also major targets for cybercriminals. Fraudulent text messages, fake parcel notifications and scam phone calls are common methods used to steal money or personal information.
Avast therefore includes features designed to detect and block scam messages and fraudulent calls.
This can be a useful addition for people who regularly use their smartphones for online banking, shopping and communication.
The exact functionality and available blocking options depend on the operating system. Technical restrictions imposed by the respective mobile platform may also affect how these features work.
Avast SecureLine VPN: Encrypted and More Private Internet Access
Antivirus software protects against malware, but it does not automatically prevent third parties from collecting information about your internet connection when you use public networks.
This is where Avast SecureLine VPN comes in.
A VPN establishes an encrypted connection to a VPN server. This makes the data traffic more difficult to intercept while it is being transmitted. At the same time, your real IP address is replaced with the IP address of the VPN server when communicating with websites and online services.
The benefits include:
- Encrypted internet connections
- Additional protection when using public Wi-Fi
- Masking of your real IP address
- Making location-based identification more difficult
- Increased privacy while browsing
- Additional protection when shopping or banking online
- Access to regional content through VPN servers in other countries
Why Is a VPN Useful on Public Wi-Fi Networks?
Public Wi-Fi networks in hotels, cafés, airports and train stations are convenient. However, users have limited control over the security of the network environment.
A VPN encrypts traffic between your device and the VPN server. This makes it more difficult for other users on the same network to intercept transmitted information.
This is particularly useful when accessing personal accounts or transmitting sensitive information while travelling.
However, expectations should remain realistic. A VPN does not make users completely anonymous and does not automatically protect against phishing, malware or tracking by services where users are logged in.
The provider’s privacy policy and data-handling practices are also important considerations.
Avast AntiTrack: Leave Fewer Digital Traces Online
Many websites, advertising networks and online services attempt to collect detailed information about their visitors. They use cookies, tracking technologies and browser fingerprinting to achieve this.
The collected information can be used to create detailed user profiles. These profiles enable personalised advertising and can reveal information about interests, habits and browsing behaviour.
Avast AntiTrack is designed to make such tracking attempts more difficult and improve online privacy.
Its features include:
- Masking the digital fingerprint
- Detecting tracking attempts
- Alerts about detected trackers
- Information about tracker identities
- Blocking certain tracking activities
- Protection against unwanted user profiling
AntiTrack is particularly interesting for users who do not want their browsing behaviour to be analysed as extensively as possible.
However, it cannot prevent every form of data collection. For example, users who are logged into Google, Facebook or other online services can still be recognised through their accounts.
Avast Cleanup Premium: Free Up Storage and Optimise Your Devices
Over time, computers and smartphones accumulate unnecessary files. Temporary data, browser leftovers, application remnants and other redundant files can consume valuable storage space.
Avast Cleanup Premium focuses on cleaning and maintaining supported devices.
Its features include:
- Detecting and removing unnecessary files
- Freeing up storage space
- Cleaning up file remnants
- Automated maintenance and regular cleaning
- Identifying unnecessary applications and bloatware
- Helping improve device performance
This can be particularly useful for devices that have accumulated a large number of applications and files over time.
However, users should not expect miracles. A cleanup utility cannot fundamentally turn an old computer into a high-performance machine. Hardware, RAM, SSD performance and installed applications continue to have a much greater impact on overall performance.
How Good Is Avast’s Antivirus Protection?
The most important aspect of any security package is its ability to protect against malware. Additional features are useful, but they matter less if the underlying malware detection is unreliable.
Avast can point to several independent test results.
AV-Comparatives named Avast a Top-Rated Product in its 2025 annual report. The software also achieved very good ratings in its protection tests.
In the Real-World Protection Test conducted by AV-Comparatives between February and May 2026, Avast achieved a protection rate of 99.3%.
COMPUTER BILD also reviewed Avast Ultimate in October 2026 and awarded it an overall rating of 1.8 (good) under the German grading system. Antivirus protection received particularly positive feedback, while the feature set and privacy aspects were assessed more critically.
These results indicate that Avast offers strong malware detection capabilities. However, they should not be confused with an independent test of every individual component included in the Ultimate package.

- AntiTrack is limited to Windows and macOS.
- Cleanup Premium is not included in the iOS feature set.
- A VPN does not provide complete anonymity or replace antivirus protection.
- VPN performance and speed should be evaluated separately.
- The provider’s privacy policy deserves careful consideration.
- Users who already have premium security software and a separate VPN may not need all the included components.
- The package does not include an integrated cloud backup service or comprehensive parental controls.
- The renewal price is significantly higher than the first-year promotional price.
How Much Does Avast Ultimate for 10 Devices Cost?
The multi-device version is particularly interesting for households and users who need to protect several devices.
At the time of checking the US Avast product page, the promotional price for the ten-device version was $69.48 for the first year. The regular annual renewal price was listed as $139.99.
This means that, during the first year, protecting up to ten devices costs less than seven euros per month for the entire package.
That can be attractive, especially if users actually make use of several included applications.
However, it is important to consider the renewal costs. After the first year, the subscription continues at the regular renewal price unless it is cancelled in time. The promotional price should therefore not be confused with the long-term cost.
Avast also advertises a 30-day money-back guarantee. The exact terms and conditions should be checked before purchasing.

Who Should Consider Avast Ultimate?
Avast Ultimate is particularly interesting for users who own several devices and want more than traditional antivirus protection.
Families and households with multiple devices: Anyone using several Windows PCs, Macs, smartphones and tablets can combine different devices under one ten-device subscription.
Self-employed professionals and business users: People who regularly work while travelling can benefit from antivirus protection, the firewall and VPN. Protecting personal and business documents is another important consideration.
Privacy-conscious internet users: Anyone looking to leave fewer digital traces online gets additional privacy tools through AntiTrack and SecureLine VPN.
Users concerned about online scams: The AI-powered features designed to identify suspicious messages, offers and deepfakes complement traditional antivirus protection.
Avast Ultimate is less attractive for users who only need antivirus protection for a single PC or already have comparable premium applications.
Final Verdict: Avast Ultimate Offers More Than Traditional Antivirus Protection
Avast Ultimate is a comprehensive security package that covers several important aspects of everyday digital life. Traditional antivirus protection forms the foundation, complemented by a firewall, ransomware and phishing protection, as well as modern AI-powered features designed to identify online scams, suspicious messages and deepfakes.
SecureLine VPN and AntiTrack also address privacy and online tracking. Cleanup Premium adds tools for device maintenance and storage optimisation.
The multi-device concept is particularly appealing. Up to ten devices can be protected under a single license. This is a practical advantage for households using a combination of Windows PCs, Macs and different smartphones.
There are, however, some limitations. Not every application is available on every operating system. VPN performance and privacy practices also deserve closer scrutiny. The significantly higher renewal price should be part of the purchasing decision.
My verdict: Anyone looking beyond basic antivirus protection and seeking a more comprehensive solution for up to ten devices will find Avast Ultimate an interesting package. The combination of antivirus protection, AI-powered anti-scam features, VPN and anti-tracking makes it particularly appealing. If you actually use several of the included components, the subscription can offer good value.
