Avast Review

Avast provides advanced virus protection to more than 435 million users around the globe. And whether you know it or not, you’ve probably used the Avast antivirus software at some point. Our Avast review found the software worthy of its title as the internet’s most popular security tool, preventing more than a billion malware attacks each month.

Currently based in Prague, Avast was founded in 1988 before becoming a private company in 2010 and eventually going public in 2018. In 2016, Avast acquired one of their largest competitors, AVG Technologies, for $1.3 billion.

Avast offers a long list of cybersecurity features that are available through three different plans, one of which is completely free. In this Avast antivirus review, we examine the quality of the service.

Key features:

  • Robust Behaviour Shield
  • Additional tools like the password manager and Avast Cleanup
  • Secure Browser allows safe browsing without ads
  • Modern interface
  • Webcam Shield

Things we liked / disliked:

  • Best in class antivirus
  • Solid free plan
  • Proprietary VPN
  • Great platform availability
  • Data collection scandal

Data Collection Scandal

In the spirit of full disclosure, we have to mention that in 2019, Avast was part of a data collection scandal that tarnished its otherwise stellar reputation.

In December of that year, reports surfaced about Avast using its browser extensions to collect a suspicious amount of user data, including sites visited, user location, search history, and social media identities. An Avast subsidiary, Jumpshot, reportedly sold this data to companies like Home Depot, Google, and Microsoft.

But since then, Avast terminated its relationship with Jumpshot, and today almost every Avast online security review applauds the company for its reliability and its unmatched dedication to online freedom. For many, the scandal is just a distant memory, and you can rest assured that the Avast online security features are still some of the best in the world.

Avast Security Features

Avast’s variety of cyber protection tools are joined together to provide a full suite of armor against any and all threats to your device. The software’s key features include antivirus protection, anti-malware, ransomware security, and firewalls – all of which are thoroughly examined in our Avast security review.

Avast Antivirus

Avast is, first and foremost, an antivirus. Like most antiviruses, it provides real-time protection by running in the background. In order to use antivirus protection, download the software from Avast’s site and install it.

The antivirus continually performs low-intensity scans and background checks to see whether any malicious files or suspicious processes have been activated. Avast malware protection also kicks in whenever you download a file from the internet or plug in a USB drive – the most common source for malicious files.

During our Avast free antivirus review, the software immediately notified us of any suspicious files and automatically isolated them. The file is placed in a Virus Chest and can then be sent for further analysis. In the meantime, it’s separated from your system and prevented from infecting your PC.

By not deleting it immediately, Avast gives you a chance to restore critical system files that are accidentally moved to the chest. However, file restoration poses a significant security risk and should only be performed by advanced users.

In addition to real-time protection, Avast runs on-demand system scans. The most extensive of these is the full virus scan, which searches your whole computer for any malicious files or executables.

While conducting our Avast malware review, we also had the option to run targeted scans for specific folders or partitions. Additionally, you can run boot-time scans to check for potential threats before the OS and other services boot up or create custom scans.

Antivirus Engine

The level of protection provided by paid or free antivirus software largely depends on the quality of its antivirus engine. The engine determines how good the antivirus is at preventing malware, including drive-by-downloads and code injection attacks, from infecting your system. Even if the malware breaches the outer defenses, an antivirus works to detect when the virus attempts a malicious action.

However, individual users are unqualified to determine whether Avast real-time protection is effective. The level of effectiveness is analyzed by independent labs that review the Avast antivirus software. The AV-Test Institute is among the more reputable organizations that conduct these tests, which serve as an important rubric for ranking the software. Avast regularly ranks among the top antiviruses on the market.

Avast Firewall

A firewall protects your computer from any potential breaches by monitoring network traffic between your device, the internet, and other networks. For example, Windows has its own firewall which improved over time. But many still regard it as being insufficient. Our Avast firewall review found that this feature is only available with paid plans.

The Avast firewall is enabled by default, and Avast advises you to leave it that way. In the software’s firewall tab, you can see all the networks your PC is connected to. It also enables you to set up a firewall network profile for each, choosing between public and private. The firewall adopts a more aggressive posture on the networks you mark as public.

You can customize how the Avast firewall behaves by altering the application rules. Here you can allow/disallow applications to connect to the internet and determine how strictly the firewall oversees these connections. In our Avast review, we found the firewall to be a pretty powerful and useful tool. It’s also one of the main incentives to sign up for a paid plan.

Behavior Shield

One of Avast’s most powerful standout features is the Behavior Shield, which continually monitors all applications running on your computer for suspicious activity. Thanks to this shield, potentially dangerous files that appeared safe at first glance and bypassed the first line of defense can get detected by Avast.

So, how exactly does the Behavior Shield operate? Our Avast Behavior Shield review can confirm the software’s efficiency in both detecting and blocking suspicious files. For example, if a music player starts running scripts, the Behavior Shield will examine the application more closely. In case of any suspicious activity, Avast will stop the application and notify you with an alert. You can then move the suspicious file to the Virus Chest, delete it altogether, or simply ignore the detection.

In order to provide this level of PC protection, Avast relies on AI technology and its vast cloud database. The Behavior Shield is effective against a whole range of cyberthreats, but especially against ransomware – one of today’s most dangerous and prevalent forms of cyber attacks.

Avast Secure Browser

Next up is the Avast Secure Browser review. During the installation of the antivirus, you’ll be offered to download and install this browser. Alternatively, you can download it from Avast’s site separately and completely free of charge.

The Secure Browser serves as a privacy-focused alternative to its widely popular counterparts like Chrome and Firefox. One of its key functions is to block online ads, which drastically improves website loading time. In that respect, it’s very similar to the Brave browser. You can fine-tune whether you want all ads removed or just the most intrusive ones.

We were very impressed with the security features during our Avast safe browser review. The browser automatically blocks malicious sites and downloads and hides everything you type online in order to prevent attackers from stealing your data. Furthermore, the Secure Browser forces sites to use encryption in order to protect your information.

The browser also prevents online tracking and stops websites from identifying you based on your browser profile. In case your credentials are leaked online, the browser notifies you immediately, giving you plenty of time to make the necessary changes.

While Avast claims that its browser is four times faster than the competition, this simply isn’t the case. A quick Avast browser review reveals that it’s much slower than Chrome for example. However, speed is not the primary focus of the Secure Browser, privacy and security are.

Avast Online Security Extension

If you’d like to improve your online privacy, you should consider the Avast Online Security browser extension. Yes, that’s the same extension that was at the center of the data collection scandal, which led to its removal from Firefox. Thankfully, Avast has since made the necessary adjustments to return to the market.

It was available for both Chrome and Firefox during our Avast Online Security extension review. Based on feedback from its 435 million users, the Avast extension is a very reliable warning system for sites that are unsafe or those with a questionable reputation. Additionally, the extension blocks sites from tracking you through cookies.

SecureLine VPN

In recent years, the vast majority of online users learned about the importance of a good VPN. Avast also offers its proprietary VPN called SecureLine, but it does not come as part of the free antivirus protection package; it can be purchased separately or acquired for free if you go with the Ultimate package.

An Avast SecureLine VPN review found that the network efficiently performs a number of functions, including hiding your online activities and browsing history from providers, government agencies, advertisers, and others. Furthermore, it can be used to access geo-blocked content. Like any good VPN, SecureLine has a no-log policy, which means it keeps no identifiable user data on its servers. However, it can’t unblock Netflix and has a small server network.

Avast Passwords

Avast also has a password manager in its arsenal, albeit a very simple one. The Avast Passwords used to be a standalone product but is now part of the free Avast browser extensions. While conducting our Avast password manager review, we found that it safely stores your credentials under one Master Password and comes with an autofill option. It can capture passwords after you log in, generate safe passwords, and tell you whether some of your passwords have been compromised.

Avast Cleanup

Avast Cleanup is one of the Avast products that isn’t really designed to improve your security. Instead, it acts a lot like the CCleaner – cleaning up your PC from unnecessary files, plugins, apps. It also cleans up the registry and optimizes the hard disk. During our Avast cleanup premium review, we found the tool to be very useful for clearing cookies and browsing history and automatically updating your applications. The Cleanup tool can be purchased for a one-time fee of $59.99.

Other Features

Avast includes several other features that safeguard your privacy. For starters, the Webcam Shield prevents malware from accessing your webcam, while the Data Shredder allows you to safely delete sensitive files and ensures they can’t be recovered. In addition, the AntiSpam feature blocks junk and phishing emails, removing the annoying and sometimes dangerous clutter from your inbox.

If you’re scared of ransomware, the Avast Ransomware Shield allows you to specify which applications are allowed access to your protected folders while protecting your files from being modified or deleted by ransomware attacks.

Ease of Use

Our Avast review highly recommends this user-friendly software to beginners. The installation process is simple, and all you have to do is download the appropriate client for your platform. You can also install some of the additional free antivirus tools like the Secure Browser. To complete the installation, restart your computer – standard practice with most antiviruses.

Once the installation is finalized, Avast will automatically boot up whenever you turn on your computer and run in the background, providing real-time protection. You can access Avast’s dashboard at any time by double-clicking the icon in the taskbar. Throughout the course of this Avast free review, the interface included four tabs located in the left bar – Status, Protection, Privacy, and Performance.

Status tells you whether your real-time protection is turned on or if you need to update your antivirus, and it also informs you if you need to restart your PC. The Protection tab houses scanning options and all the different Avast shields, allowing you to fine-tune each one according to your needs. In the Privacy tab, you’ll find the password manager, Data Shredder, VPN, Webcam Shield, and other privacy settings. For driver/software updates, you’ll have to access the Performance tab where you’ll also find the Cleanup Premium tool.

Platform Availability

Most of our tests for this review of Avast were conducted on PC. But Avast premium security is available on numerous platforms, including Windows, macOS, Android, iPhone, Tablet, and as an extension for Chrome/Firefox. You can select which platform you wish to use during the download process.

For smartphones, you need the Avast app directly from either the Google Play store or the Apple store. The vast majority of the features we covered are available on all platforms.

Avast Pricing Plans

There are three major Avast plans: Free, Premium Security, and Ultimate. The Avast pricing plans act as bundles, grouping multiple Avast products. Some of the Avast products can also be downloaded as standalone tools.

The Free plan gets you full-fledged antivirus protection, the Sandbox, as well as anti-ransomware shields. You also get access to the rudimentary password manager for free. This plan is free to use without any limitations.

The Premium Security package adds the Data Shredder, Webcam Shield, and an auto-updater. The price for a single device is $39.99/year, and it’ll cost you $49.99/year to cover 10 devices with this package.

The Avast Ultimate includes practically every single tool that we came across during our Avast ultimate review. You get the VPN, the Cleanup Premium tool, the premium version of the Password manager, and everything included in the previous plans. Avast Ultimate will cost you $69.9/year for a single device or $79.99/year for 10 devices. These prices are currently heavily discounted so now is probably the best time to snatch this antivirus.

avast antivirus review - pricing plans

In addition to these individual plans, Avast also offers business packages. You can head over to their site and compare Avast products. The prices of the Business plans depend on the duration of the license, as well as the number of devices that you need to protect.

After conducting our Avast Premium security review, we arrived at the conclusion that this is the best option for individual users. It’s affordable and provides you with all the protection you might need. The Ultimate plan is also impressive, but not everyone will feel that the tools included are worth the price. On the other hand, users who are simply looking for reliable antivirus protection will be more than happy with the Free plan.

So, is Avast premium worth it? If you’re still not sure, you can always sign up for the 30-day free trial period that’s available with most of the paid plans and doesn’t require a credit card. All paid plans also come with a 30-day money-back guarantee.

Final Thoughts of Our Avast Review

Avast is undoubtedly one of the best free antivirus options on the market. After conducting our tests, we can safely say that the company still deserves its place among the world’s top three antivirus providers. While the data collection scandal had a negative impact on Avast’s reputation, the company moved quickly to correct its mistakes and sever ties with the problematic subsidiary. Since then, it passed all security checks with flying colors and offers a plethora of tools that are unmatched by many of its competitors. Additionally, its antivirus engine is still among the best in the field. On the question of Avast free vs paid, we believe that the Premium Security plan is optimal for most users.

Things we liked / disliked:

  • Best in class antivirus
  • Solid free plan
  • Proprietary VPN
  • Great platform availability
  • Data collection scandal
