Avast Antivirus Review

Avast: A Brief History

Avast has been around since the late 1980s, but it didn’t become popular until after 2000 when it started offering antivirus software with a freemium model. Unlike other antivirus software at the time that charged a yearly licensing fee, Avast opted to offer customers a more basic version of its software for free with an option to upgrade to a premium plan whenever they so desire. This resulted in a boom in users, reaching the 20 million mark by 2006.1

Since then, Avast grew its antivirus empire by acquiring other companies. For example, Avast’s mobile antivirus apps were developed following the company’s acquisition of Inmite, a mobile app developer. Avast also merged with other antivirus brands to further cement its position. In 2017, Avast merged with AVG, and in 2022, it merged with NortonLifeLock to form Gen, a portfolio of high-quality cybersecurity tools.

How Does Avast Antivirus Affect Our Devices?

As we said, we tested out Avast Antivirus on a Macbook Pro. Our laptop has seen better days, but Avast still worked perfectly fine on the device.

As expected, Avast offers protection through malware scanning. It runs in the background to keep malware at bay whenever we open files or do something on our laptop – also known as on-access scanning – but it also lets us scan on-demand through the app’s Smart Scan button. The Smart Scan button, which was also present in the AVG app when we reviewed AVG, scans for a number of cyberthreats, including:

• Different types of malware
• Spoofing
• Ransomware
• Spyware
• Dangerous downloads or websites
• Malicious email attachments
• Remote access attacks
• Intruders on our devices (hackers, spy programs, etc.)
• Phishing
• Fake websites

That’s more than what most antivirus software we’ve tested scans for. In addition, since we sprang for the Premium version of the software, we also got a firewall, a form of network security that filters out untrustworthy traffic.2 All in all, it’s a great start for Avast. With its multiple scan options, we knew from the start that it would offer good malware protection, but let’s dig deeper and see what else we can find.

The Installation Process

There are two ways to buy Avast software. You can download the free version and then upgrade once the app is installed – perfect if you want to test out Avast first. You can also buy directly from the website. After paying, you’ll be able to download the full premium version of the software.

Since we wanted to test out the free version first, we opted for the first option. That downloading process only took a few minutes, and from there, the app told us that we had several areas in which ransomware was detected. Anyone would be alarmed, but we’ve been testing antivirus software long enough to know not to panic. First, we know that our Macbook is in tip-top shape. Secondly, we know that freemium antivirus software use this kind of marketing ploy to get users to buy the premium version. There’s no fooling us, Avast!

We don’t appreciate the bait and switch, although these sorts of deceptions aren’t uncommon with antivirus software, unfortunately; Norton, for example, also had a lot of confusing pop-ups meant to get us to sign up for their paid subscription when we tested the free version, which you can read more about in our Norton Antivirus Plus review.

Another confusing thing was that the pricing on the app differed from the pricing displayed on their website, although the former ended up being accurate. All in all, aside from the somewhat misleading setup and inaccurate prices, Avast was really easy to set up, and definitely didn’t require cybersecurity experts like ourselves.

Using Avast Antivirus: Our Experience

Once we were set up with the app and our subscription, the main page was divided into four sections: Core Shields and Virus Chest, which were also part of the free account, and then Wi-Fi Inspector and Ransomware Shield, part of our Premium subscription only.

• Core Shields: The Core Shields were pretty self-explanatory, constantly exploring our Macbook for malware and blocking it as soon as it’s detected. We could turn off specific functions of Core Shield if we wanted to, but we decided to keep them all on for maximum protection. Let’s get a bit more specific.
  • File shield: Since we’ve had this computer for nine years, we have a ton of files on it, all of which Avast scanned for malware. Somehow, none was found!
  • Web shield: This shield would’ve blocked any unsafe downloads from the web as well as web attacks. We download a lot of files onto our Mac for work, so this made us feel more comfortable, especially when it came to torrenting.
  • Email shield: A common method of phishing attacks and malware is through email attachments, so Avast scanned our email to automatically block attachments it deemed dangerous.
  • Real site: Finally, real site made sure that the sites we spend money on, and manage our money on like the Wells Fargo site, are safe and secure. With the pandemic, we’ve been doing more and more shopping online, so this feature is essential for anyone involved with e-commerce or online banking.
• Virus Chest: If the Avast app had found any viruses, it would’ve stored them in the Virus Chest, where they couldn’t harm the rest of our computer. That was where we put the five viruses we tested with Avast, which you’ll hear about in a second.
• Wi-Fi Inspector: Since we typically work from a shared co-working space (yes, we live in Brooklyn and drink kombucha and are total cliches), the Wi-Fi Inspector showed us everyone who was connected to the space’s Wi-Fi network, which ended up being over 10 devices. It told us that all of the devices were secure, but if we were on a home network, it would’ve been really useful to see people stealing our Wi-Fi. That’s why it’s important to password protect your Wi-Fi network, folks!
• Ransomware Shield: Finally, the Ransomware Shield, as you would imagine, monitored our computer for ransomware and made sure that apps couldn’t keep our data hostage, be it our sensitive files or photos. We could decide which folders were protected, manually adding new folders to the main documents and pictures folders that had uploaded automatically.

Those were the four main functions of the app and overall, it was really easy to use and very clear. Again, had we not signed up for Premium, we would’ve only been able to use the Core Shield and Virus Chest; there wouldn’t have been any detection for ransomware, our Wi-Fi network or phishing, the leading cause of cyber attacks.

Smart Scan: Is it Really Smart?

Once we were done clicking on those four services, we ran a Smart Scan on our entire computer. Not to be confused with a full scan, the Smart Scan feature scans just a portion of the device’s files. In our case, it scanned about 2,000 files. However, the “smart” part comes from the fact that it scans the places where malware usually hides, like the Windows Registry for Windows and .plist files for Macs.

Come to find, Avast’s scan time is one of the fastest in the market. Our Smart Scan took less than 10 minutes. We got up to brew ourselves coffee and it was done before we even got back. This was exponentially faster than McAfee, which took about five hours to finish the first full scan during our McAfee review. Then again, Avast’s Smart Scan scans significantly fewer files – 2,080, to be exact – whereas McAfee’s full scan looked at over 12,000 files.

Avast also offers full scans, under the guide Deep Scan. We tried out this feature and fortunately, like the Smart Scan, it didn’t detect anything suspicious. The Deep Scan, in our experience, runs for about 45 minutes to over one hour, depending on whether you’re using the device while the scan is on-going. And remember, we’re using a laptop that’s over 10 years old, so it could run faster if you have a newer device (or if your device isn’t as full of memes as ours).

All in all we found Avast really simple to use and loved the clear interface, but one thing that was annoying was a pop-up trying to get us to buy additional Avast products, like a cookie-blocker. We don’t like ads in general, especially from a service we paid for literally seconds earlier. Being upsold simply never feels great! However, there was only one pop-up, so Avast wasn’t too aggressive about its sales overall.

Also, if we might offer Avast a little interface suggestion, perhaps a button for a Deep Scan on the app’s homepage would make things a bit easier. As it stands, the Deep Scan feature is hidden in the settings, so there’s no way to activate it right from the start. An option to choose between Smart Scan and Deep Scan would be helpful.

Testing Avast for Multiple Viruses

Simply scanning our Macbook as is for viruses wasn’t good enough for our testing. To find out if Avast could really find viruses, as opposed to there just being none on our laptop, we downloaded (but didn’t open!) five different files containing everything from adware to spyware to even Trojan malware. We know viruses come in all different forms, so we wanted to use these files across all of the antivirus software that we tested to see how they performed.

Overall, Avast detected three out of five, while two remained undetected by their software. While 60 percent may not sound great, it’s actually pretty average when it comes to antivirus software; of the roughly 40 top antivirus softwares that we’ve tested, only two detected 100 percent of the viruses, believe it or not. Let’s talk a little more about each.

• XLSX file: If we had clicked on it, this seemingly innocent Excel spreadsheet would’ve tried to convince us to disable Avast and enable their macros, then steal our sensitive information like our web history and passwords. Only 34 percent of the different antivirus software we tested detected it, and unfortunately, Avast fell into the majority, not detecting it.
• EXE file: The virus detected by 66 percent of antivirus software was an EXE file that enables debug privileges and tries to steal sensitive data, like the websites we’ve visited and our login credentials. In this case, Avast fell into the majority, detecting the virus during the Smart Scan.
• DOC file: When a user opens or closes this document, this virus embeds a macro with malware, detected by 36 percent of all antivirus programs we tested out. Avast was part of this minority! Two for three so far, not half bad.
• XLSM file: Only 35 percent of the antivirus programs detected this XLSM file, and unfortunately, Avast fell into the majority, not detecting this high-reputation virus.
• XLS file: Finally, when we tested out this Excel sheet virus that 51 percent of the softwares could detect, Avast detected it. That’s good news, because this virus, like the XLSX file, would have tried to convince us to take down Avast before putting malware on our computer. Fortunately, Avast detected this virus so we didn’t have to worry when working in Excel (or in any other desktop app, for that matter).

Here’s an overview of our virus testing with Avast:

Overall, we were happy with how Avast performed in our test in general. While no antivirus software is 100 percent effective, Avast certainly met our standards in terms of digital security and virus detection.

That said, we can’t deny the fact that there are antiviruses that could find all five viruses we use for testing. These are Bitdefender and Kaspersky. As far as virus detection goes, they are the gold standard. However, they also have weaknesses, like Bitdefender’s less-than-intuitive app or Kaspersky’s shaky reputation. To learn more if they’re better options for you, check out our Bitdefender review and Kaspersky review.

How Avast Antivirus Performed in Lab Tests

Aside from our own extensive testing, we also looked at independent lab data from AV Test3 to see their results for Avast. In their latest testing of Avast, the software scored a six out of six score across the board. Those are impressive scores. Additionally, it was able to detect 100-percent of widespread and prevalent malware.

AV-Test’s results show that Avast is capable of staying on top of malware trends. We agree with this; during our tests, Avast would update its malware database every few hours. As new types of malware are discovered, Avast immediately updates its database to ensure that every device under its protection remains protected from the latest threats.

Avast Antivirus Pricing

Now, since Avast’s pricing was different on the app versus the website, we’re going to use the website as our gold standard, but note that these prices are subject to change; to see the most information, read our page specifically on Avast’s pricing.

Premium Service Pricing

We paid $50.28 for one year of Premium service on our Mac, although we could’ve paid a roughly extra $20 to cover nine more devices. One thing to note is that if you want the antivirus software on your mobile device or tablet, it’s free. Another thing? The prices will go up after the first year for the paid subscriptions, so make sure you keep that in mind.

Speaking of first-year prices, Avast has a subscription called Avast One, which rolls together all of Avast’s digital security tools (antivirus, VPN, device booster, etc.) into one subscription. Weirdly, the first year prices of Avast One are the same as Avast Premium, but the former offers more features and covers more devices than the latter.

To muddle things even further, Avast recently added Avast One Platinum to its list of products for the price of $119.88 for the first year. Platinum offers features similar to the Avast One for families, but it adds in identity protection for up to six family members, making Avast one of the latest to join the antivirus brands that offer identity protection features. This movement was kickstarted by NortonLifeLock, now an Avast partner. You can read our NortonLifeLock identity protection review to learn more about the benefits of antivirus software with identity protections.

Back to Avast. To sum up Avast’s antivirus options, here’s a table that shows Avast’s first-year pricing, along with their current renewal rates. Note that the renewal rates may change anytime, and when it’s your turn to renew, the current rates will apply.

Unfortunately, the discounted first-year price is a common practice in the antivirus industry, so you’re going to have to read the fine print before signing up for any service. For their first-year prices, we find Avast’s subscriptions cost-effective. As a point of comparison, we listed below pricing from other antivirus software. And as you’ll see, Avast is on the lower end.

However, you have to consider the fact that Avast’s pricing for most of its subscriptions almost doubles after the first year. Are they still worth it by then? We’ll leave it for you to decide. The first-year prices are worth it, in our opinion, so if you like Avast, maybe give that a try and then revisit your decision towards the end of the first year. If you cancel 30 days before the end of your subscription, it will not renew automatically and you’ll be free to try out other antivirus software.

You can find more such insights in our Avast pricing page.

Premium vs. Free

Let’s jog back to that free service. While it has blocking for things like viruses and spyware, it lacks protection against ransomware and phishing plus weak Wi-Fi connections. For the whole kit and caboodle, we recommend that you use the Premium service like we did.

Avast Antivirus App

While we downloaded Avast’s Mac app, they also have apps for Windows, iOS and Android devices, as we mentioned before. On Google Play, the app is called Avast Antivirus- Scan & Remove Virus Cleaner, while the iOS version is named Avast Security & Privacy. Both apps have 4.7-star ratings, which is pretty high. Although we only tested the macOS app, we’re glad that iPhone and Android users had good experiences.
