Today we have increased connectivity to the Internet through almost all of the devices. Hence, assured security, improved privacy & optimized performance are of key significance.

Numerous incidents are reported daily where compromise in security has led to the loss of a substantial amount of users' data online. Furthermore, with so many apps on our devices, junk files, old stray data, useless apps, and more start eating up precious resources resulting in poor performance.

To ensure that none of the current tech issues reaches you, Avast has developed its latest app – Avast One. In this Avast One review, I will go through the aspects which secure your devices against malware & security threats through its award-winning Antivirus engine. It protects your privacy through an inbuilt VPN and optimizes your devices with its in-built optimizing tools.

Avast One Review: Key Features

Avast One works on three major fronts for your devices- Protection, Privacy & Maintenance.

New Interface of Avast One


The built-in antivirus protects all your devices from viruses, malware, and even ransomware. It works in real-time by gathering intelligence from the largest threat-detection network composed of hundreds of millions of Avast users.

The advanced Ransomware Protection helps prevent device data from being taken hostage, stolen, or encrypted by hackers.

Furthermore, the advanced Firewall helps prevent unauthorized access to your system via Wi-Fi. It also detects & blocks dangerous downloads & websites and prevents malware from downloading onto your PC while browsing the Internet.


The main element to ensure online privacy is the VPN. Avast One's VPN offers additional privacy whenever you're online. It secures your Internet connection with military-grade AES encryption & ensures that none of your online activities are spied on by external agencies.

Avast One also takes privacy protection a step further by blocking all Webcam access without your prior consent. It also secures all the passwords saved on your browsers, ensuring no one can access them without your permission.


The Software Updater finds and installs available software updates for some of the most popular applications in just a few clicks in a single window.

The Disk Cleaner cleans dozens of file types, removes broken shortcuts, and clears all junk files from your browsers to reclaim wasted storage space.

Also, the Driver Updater automatically checks for any new drivers available for your installed hardware & informs you when updates are available. You can then install them in just a few clicks from within Avast One.

Avast One Review: Interface & Ease of Use

Downloading & installing Avast One is fairly simple and can be done by any user. Once you download the file from the official website, proceed toward installation.

The best part I like about Avast One is the new, trendy, illustration-based, and fresh color theme used in the entire app. It brings a fresh perspective toward security products.

Avast One Smart Scan in Progress

Once installed, the app will initially ask you to run a short Smart Scan. The Smart Scan looks for any possible Browser threats, Viruses & malware, and Advanced issues on your system. It pockets of junk files that you can delete to free up space. It also allows you to schedule an automatic Smart Scan once every month at the end of the scan window.

Avast One Scan Completion

The Home Screen

It has a main menu on the left panel hosting Home, Explore, Messages & Account tabs.

Avast One Homescreen


It contains all the options for further fine-tuning the app that you can run from within it for extra security settings. It is broadly divided into Device Protection, Online Privacy & Smooth Performance options, which are subdivided into further sub-categories.


Online Safety Score feature in Avast One

It contains any security alerts & messages that Avast One might want you to know.

Online Safety Score, available on Windows, Mac, Android and iOS, gives you a score based on your Windows system or Android device's safety. The tool also provides tips to boost your safety online.


has information about your subscription period, app Settings, Feedback options, FAQ section, and a Rescue Centre.

All in all, the app is very easy to use. It has all the essential tools right at eye level and does its job perfectly.

Avast One Review: Functionality

Device Protection

Scan Center

Scan Center under Device Protection includes different scan types - Deep, Targeted, and Boot-Time Scan.

Avast One Scan Center

File Shield

Avast One File Protection

File Shield scans your PC in realtime for malicious threats in programs and files. If malware is detected, File Shield immediately stops the program or file & prevents it from infecting your PC by moving it to Quarantine.

File Shield is enabled by default in Avast One. Furthermore, you can also choose your preferred actions for types of detected threats, including Malware & Potentially Unwanted Programs or PUPs, or Add Exceptions for a file or folder so that File Shield won't scan it.

Web Shield

Avast One Web Browsing Protection

Web Shield scans for any data that is transferred when you are browsing the Internet in real time. It protects your system from malicious scripts which these harmful sites can download and run on your PC.

In addition, Web Shield can also block certain websites, enable HTTPS protocol & run script scanning. It even goes a step beyond protecting you against botnets designed to hack your data or remotely control your PC.

Ransomware Protection

Ransomware Protection

Ransomware attacks usually target personal or sensitive data stored on devices by stealing, modifying, deleting, or encrypting it. This feature secures important files by automatically scanning and securing them against untrusted applications. It can automatically detect personal data on your system, but you can also specify any other folders you wish to protect.

Additionally, you can specify which applications on your system can modify the files in your protected folders and which applications always remain blocked.


Firewall Protection in Avast One

The Firewall actively monitors all incoming & outgoing network traffic between your PC and the outside world. It works to protect you from any unauthorized communication and intrusions.

Furthermore, you can also block network and Internet communication for specific applications on your device.


Quarantine Files in Avast One

Quarantine is a secured & restricted space where you can store potentially dangerous files until further action. You can delete, repair, or send these files to Avast Threat Labs for further analysis.

Files in the Quarantine folder cannot run or access your system and data. Hence, any malicious code within a file cannot harm your PC. Any suspicious files detected during a PC scan are instantly transferred to the Quarantine.

Network Inspector

Avast One Network Inspector

In suspicious times you can initiate a network scan to find vulnerable devices or potential security issues that can jeopardize your system safety.

The feature looks through home networks and connected devices and thoroughly looks for weak passwords to protect your device.

Sensitive Data Shield (For Paid Users Only)

Sensitive Dalata Protection

Most of your devices usually contain sensitive data. Sensitive documents usually contain your personal information, which could compromise your privacy and leaked identity.

The Sensitive Data Shield in Avast One scans and protects your sensitive personal documents against any unauthorized access attempts. You can use it to choose which applications and users have the right to access your private data.

Sensitive Data Shield is a paid feature. You can access multiple options under Sensitive Data Shield from the Explore tab.

Web Hijack Guard (For Paid Users Only)

Web Hijack Guard

On the Web, some malicious programs can stealthily redirect you from an original URL to an unauthentic website without your notice. It is done to acquire sensitive information such as usernames, passwords, credit cards, or bank details.

The Web Hijack Guard secures you against any DNS hijacking attempts on your system. It works by translating the web page address you enter into your browser to the IP address of the target web server. Web Hijack Guard connects your browser and Avast's own DNS server to ensure that only authentic websites are displayed every time.

Webcam Protection (For Paid Users Only)

Webcam Protection

Nowadays, multiple attempts exist to capture images or videos from your webcams by malicious software or websites without your knowledge. It can lead to highly compromised privacy.

The Webcam Protection feature prevents any application or malware from accessing your PC's webcam without your consent. With Webcam Protection enabled, any untrusted applications cannot capture images or videos and send them outside your PC.

Online Privacy

VPN Secure Connection

Avast One VPN review

Avast One uses a Military Grade 256-Bit AES encryption protocol for utmost security. In the paid version, you can choose to access servers in several locations enabling you to bypass geo-blocking restrictions and access your favorite content even while traveling. You can easily enable the Avast SecureLine VPN connection from the Explore tab.

However, note that the free version has some limitations. The VPN on the free version will not allow you to change your default set location. Also, with the free version, you only get to use 5GB of data per week, post which you would require to buy a paid license.

Compared to Avast, Surfshark VPN has 3200+ servers in 100 countries, and you can connect to unlimited simultaneous connections with a single account. Avast VPN lets you connect upto 10 devices simultaneously. You will find Split tunneling and Multi-hop features missing from Avast VPN.

Password Protection

The Password Protection feature informs you if any of your passwords are leaked online in any data breach. Furthermore, it secures all your passwords stored in your web browsers against theft attempts.

You can access Password Protection from the Explore tab. However, remember the exact functionality of Password Protection varies according to your version of Avast One.

Protect your Passwords

In the free version, i.e., Avast One Essential, the process is manual. You can run a one-time breach check for all your email addresses & it informs you if any of your online accounts that use your email address have already been involved in a data breach.

However, post this, Password Protection will not continue to automatically monitor for any new data breaches. Thus, Avast recommends running regular manual checks if you're using a free version.

Detecting compromised passwords

In the paid version, the monitoring process is automated. Depending on your plan, you can add up to 5 email addresses to monitor data breach attempts. It also informs you about any previous data breaches involving your monitored email addresses.

Avast One will automatically keep monitoring your email IDs in real time for any new data breaches. You will get an alert if a breach is detected.

Clear Browsing Data

Clear Browser Data

This feature scans for junk browsing data that eats memory in your system and facilitates third-party advertisers to track your browsing habits and history. You can clear everything or select some parts of your browsing data.

Privacy Advisor

Avast One Privacy Advisor Settings

Privacy Advisor provides step-by-step instructions that you can follow to protect your digital privacy on social media apps like Google, Facebook, Linkedin, etc. 

By adjusting the privacy settings, you will control who can and which apps can access your personal information. This feature is available on Avast Free Essential and Avast One Individual/Family plans.

Email Guardian

Email Guardian

Email Guardian is a cloud-based feature that will scan your email attachments to check for malware in real time. This feature works only if you use email clients like Microsoft Outlook or Mozilla Thunderbird on your desktop.

Private Mode

Avast One Private Mode Settings

Private Mode is a privacy feature that offers a more private browsing experience. It prevents your web browsing history from being saved and tracked. When Private Mode is turned on, it enables VPN Secure Connection and Tracking Prevention so that you can privately browse the web without any privacy concerns.

Tracking Prevention

Avast One Tracking Prevention

This feature works using Avast's patented anti-fingerprinting technology. It protects your privacy online by preventing companies from tracking and targeting your browsing behavior.

For this feature to work as expected, you must turn on Tracking Prevention. In the image above, Tracking Prevention is enabled.

Smooth Performance

PC Speedup

Speed up your devices

It scans for any applications running in the PC's background and allows you to safely put them to sleep. It helps allocate vital resources to active applications and greatly improves your PC's performance.

To improve PC speed and overall performance, you can get dedicated PC Maintenance tools like Advanced SystemCare ProCCleaner Pro, and iolo products, to name a few.

Software Updater

Software Updater

Hackers often leverage bugs in common software to enter into your system and mine for sensitive data. Software Updater ensures all your common third-party software is always up to date to eliminate potential security risks. Software Updater displays a list of the most popular programs installed on your PC and allows you to easily update it. You can access this list through the Explore tab and by clicking on Software Updater.

However, again note that Avast One informs you about any available updates by default, but you will need to manually download and install them via the Software Updater screen. If you use the paid version, you can change this default setting to find & install updates automatically.

In the free version, automatic updates are disabled.

IObit has a dedicated program, IObit Software Updater Pro, that automatically updates software as per your schedule, thus keeping all your must-have software up to date. There is a free version of the program with limited features.

Disk Cleaner

Disk Cleaner

Disk Cleaner scans for and safely deletes all junk files using a large amount of disk space on your PC. You can choose and customize the types of files you want Avast to scan for and delete only the files you want. You can even change the settings so that Avast can automatically clean your device as per your given preferences.

Compared to Avast Cleanup, Advanced Systemcare is a powerful cleaning utilty that leverages AI technology to optimize your PC performace. Learn more in this Avast Cleanup Vs Advanced Systemcare comparison.

Driver Updater

Update Device Drivers

Bad drivers can cause crashes, security issues & generally slower PCs. Driver Updater scans and updates your hardware for outdated or broken drivers to prevent these problems. You can learn more in this Avast Driver Updater Review.

This feature is available for paid customers only. The free trial users can avail this feature during the trial period.

Looking for a program that can update and install drivers in offline mode? We recommend using IObit Driver Booster Pro. There is also a free version available.

Avast One Review: Independent Antivirus Testing Labs

Avast Antivirus software is included in all the major antivrus Testing Labs - AV-Test, AV-Comparatives, VB100, and SE Labs with top scores.

It includes comprehensive Avast antivirus protection, limited VPN, Password Protection, and the basic Software Updater. These features ensure you get almost all of the Security, Privacy & System Maintenance options.
