Bitdefender vs. Avast: which offers better protection?

One of the hardest things to lớn compare between two antiviruses is their protection capabilities. The chất lượng of the antivirut depends not only on the ability lớn detect và remove malware. You want khổng lồ make sure that your service is removing only the harmful files and not deleting important system data. That is why you also have to lớn factor in false-positives.

According khổng lồ AV-TEST Institute’s data, when it comes to lớn protection, both Avast và Bitdefender score 6 points on Windows và 5.5 points on Mac. So, it’s fair to say that you should expect a fairly similar degree of performance, whichever you pick. With that said, Bitdefender offers a more comprehensive defensive sầu feature danh sách, which puts it over the edge.


Malware protection

Avast’s capabilities lớn protect you against malware will heavily depkết thúc on your subscription version. This is because Avast heavily focuses on frequent background rescans for threats that already are on the inside. With the paid version, there is a much bigger focus on network protection. So, potentially the amount of malware that you have sầu to deal with will be significantly lower because most of the junk won’t end up on your device. It won’t pass the website countermeasures.


To some extent, the same applies khổng lồ Bitdefender, however, the service has much better network safety tools even on its most basic version. So, you won’t be left with only the antivi khuẩn scanner & real-time protection. There are several tools that should help you avoid frequent scans. That saves not only your device’s resources but your time as well.



Where Bitdefender lags behind is in background scans. It takes about twice as long to lớn complete a full system scan with Bitdefender as it would be with Avast. My test unit has a relatively uncluttered 256 GB SSD drive sầu, & it still took almost two hours. The difference isn’t as huge with quichồng scans, but Avast just performs a little better. Though, a downside is that when you’re scanning with Avast, you pretty much can’t vì anything else with your device. With Bitdefender, some system reserves are left, so it’s possible khổng lồ browse the news or write an email without crashing your system.

Firewall protection

Both providers have network security toolkits. My impression is that Avast spent too much time to make their Network protection interface to lớn look pretty và forgot about its functionality. You can perform various scans, but they rarely tell you anything useful. For the most part, the service cannot identify whether some of the unknown devices on the network are malicious or not.

What redeems Avast is that you can customize your firewall’s strictness. It’s quite easy lớn go overboard, so make sure you’re not messing with the ports your household members are using.


Bitdefender doesn’t have anything spectacular when it comes to lớn firewall customization either. Regardless, the whole feature offers detailed information và works in the background. You can just set it up và forget till you get a notification that you’re trying to access a suspicious connection. Overall, Bitdefender’s firewall is a bit more functional và convenient.

Which has better features – Bitdefender or Avast?

Judging purely from the length of the feature lists, it’s clear that Bitdefender (which appears at #1 on our best antivi khuẩn list) is so far ahead of Avast that it’s hardly a competition. If you’re using Windows, that is.

When looked at from the perspective of multi-platform support, Avast is somewhat better at bringing the feature to lớn Apple devices. However, Windows is most in need of antivi khuẩn software, therefore, I consider those features more important.


Shared features

Let’s explore the features that both Bitdefender & Avast have in comtháng.

Wifi protection
Ransomware protection
Safe browsing
Webcam/microphone protection
Additional browser
File shredder
Optimization tool
Anti-theft tools

Bitdefender’s Network Threat Prevention is an Internet security toolkit that protects your trang chính network against known vulnerabilities, exploits, botnet URLs, & other similar threats. Similarly, Avast offers Wifi network security. Essentially, this is a monitoring tool, ensuring no malicious agents are on the same network. It also includes DNS cache protection.

Both Bitdefender và Avast offer ransomware protection. When it comes lớn Bitdefender, the program also makes copies of your most important files with a possibility to lớn restore them in case you’d become a victyên ổn of ransomware.

As for outdated software, you won’t go wrong with neither Bitdefender nor Avast. Bitdefender’s feature Vulnerability Assessment analyses your network, device properties, used software & gives you a personalized security report giving you tips on how you could make yourself even safer. Similarly, Avast has a Software Updater, which will update your programs automatically.

In addition, both Bitdefender & Avast have sầu an optimization feature, or a registry cleaner, that clears up some space and makes your startup a bit more efficient.

If you’re concerned about trackers, you’ll appreciate Bitdefender’s Anti-tracker feature. It’s a general-purpose blocker designed lớn minimize the tracking that you encounter when browsing the web. Similarly, Avast also offers an anti-traông chồng tool in its Premium plan.


If you occasionally need to use a VPN, you’ll lượt thích the fact that all versions of Bitdefender include a VPN. Granted, it is limited lớn 200 MB/day, but still useful in certain situations. Now, if you want a VPN with Avast, you should invest in Avast Ultimate.

As most anti-malware applications, Bitdefender and Avast offer a tệp tin shredder. It’s a tool that allows you to delete files without the possibility khổng lồ recover them. Very useful in cases when you work with large volumes of someone’s private data.

An essential feature nowadays, webcam và microphone protection is offered by both Avast & Bitdefender. It denies all suspicious requests to lớn your camera or microphone. That way, you can know for sure that no one is listening to lớn your conversation or spying on you through a webcam.

You might also like Bitdefender’s Anti-Theft tools – a suite of anti-theft measures that go from locking up your device to lớn its location tracking. It’s especially useful because it’s available on all types of devices. Meanwhile, Avast offers such a feature only on Android.

There’s one more interesting thing. Both antivirus programs come with a browser that you might find pretty useful. In the case of Bitdefender, you get the Safepay browser, which is built with secure payments in mind. Meanwhile, Avast has Avast Secure Browser, which blocks ads và trackers.

Unique features

After looking at the table that displays quality features, you might notice that Bitdefender offers much more than Avast.

Rescue environment
Secure sandbox
Adjustable profiles
Password manager
Parental controls
Software updater

For example, it has a feature called Rescue Environment – a malware removal tool that gets the job done when the device is rebooting. This is a must-have sầu feature because you can’t remove some rootkits when you’re booted into the system, which is where you perform most of your system scans

Next, Bitdefender detects what you’re doing with your device to lớn toggle particular modes in order not khổng lồ bother you when you’d lượt thích some privacy, i.e., when watching a movie or playing a game. This is called Adjustable profiles.


I also like how Bitdefender offers its own password manager. It allows for easier management of trương mục credentials, syncing them between all your devices. The tool can also be used for storing payment information.

There’s also an additional tin nhắn filter compatible with most popular mailboxes. Using it, you can phối up spam filters lớn filter out unwanted emails.

If you need khổng lồ, you can also make use of Bitdefender’s parental controls. This feature lets you set up smart device limits and control how the device can be used và which webpages are available. If you want the parental controls tool with Avast, you have sầu to get a totally separate ứng dụng, which is compatible only with Android & iOS.

However, there’s one feature that only Avast has. It’s called Secure sandbox. If you downloaded a suspicious ứng dụng, you can run it in an isolated sandbox to lớn determine whether it’s safe. It won’t spread khổng lồ other system files, so it’s a convenient method khổng lồ kiểm tra up.

Impact on PC performance

When you look at the amount of bloatware that Avast tries to lớn smuggle in with their installation, you can’t help but start wondering that maybe they spent a little too much time with trojan horses analytics. The same can be said about the amount of memory that the service occupies. So, instead of malware eating up your resources, you now have sầu Avast to mistake for a crypto miner. This is worse on weaker devices, so be aware. If you’re shooting for performance, you probably won’t get it with Avast.

Bitdefender isn’t the leanest application, either. Somehow, it takes several times more storage space than Avast but performs better. A lot of it has to lớn bởi with their smart protệp tin management, so when it’s in full background check mode, you might be away from your system. This antivirus adapts khổng lồ you, not the other way around.


If someone says it’s impossible khổng lồ get a good service for không tính phí, they probably haven’t heard about Bitdefender. This provider breaks all the usual conventions by giving many useful features for free và even allowing customer support. For the truly budget-conscious, that’s all the information that they need. Even then, the paid plans don’t bite, at least when we’re talking about the first year.

Premium/Antivi khuẩn Plus$34.99/year$34.99
Total Security/Ultimate$39.98/year$59.99
Check PricingCheông xã Pricing

From this perspective sầu, Avast just looks bad. Their không tính tiền edition is more of a reminder of what you’re missing out on rather than a service intended for actual people. How else would you justify constant pop-ups offering lớn upgrade? The truth is that upgrading is hardly worth it because, for a hefty price bump, you’re barely getting an improvement on what Bitdefender is offering for không tính tiền.


Apps và interface: which is more user-friendly?

You don’t even have to lớn be a registered user lớn tải về the software. However, the installation itself isn’t too convenient, & this applies to lớn both providers. Bitdefender only downloads as a 13 MB executable file that downloads the rest of the package (going up lớn 400 MB). That’s a lot of data files, và it seems that they might be experiencing a heavier load because the downloads are painfully slow. So, it takes some time to lớn phối it up, but your experience might be different.

Avast is much quicker in this regard, but they’re guilty of much worse things. During installation, they’re one of the services that add tiny checkboxes with by mặc định toggled downloads for things lượt thích Opera or Avast Secure Browser. Most users won’t be attentive enough to lớn remove sầu them, much less understand what they’re agreeing khổng lồ. What Avast could vì chưng, at least, is not lớn make them pre-checked by mặc định.

When you enter the apps themselves, there isn’t much to lớn criticize. Both are easy lớn use, and you’ll quickly find what you need. However, Avast continues khổng lồ be a sketchy service even when you eventually phối it up. Prepare lớn be heavily bombarded with pop-up reminders to tăng cấp lớn a paid version. Bitdefender is acting much more reasonably và are treating you as their client even if you’re using their miễn phí version. Such extortion tactics that Avast uses should be a thing of the past.


Desktop apps

When it comes to lớn Bitdefender, you have sầu several ứng dụng options. You can just install the malware scanner or pichồng the whole suite. This gives you the flexibility lớn customize your installation a bit. Then, there are also options to install their VPN service separately. In short, Bitdefender offers a lot of options khổng lồ mix up the service on desktop, allowing you to skip the features or even the full tiện ích.


Avast has only one option – their full tiện ích that doesn’t change even if you upgrade your plan. What upgrading your plan does is just removes the paywall. So, essentially you bởi vì have the required files at the ready, but you’re denied access khổng lồ them because of your subscription plan. From the user’s perspective sầu, it makes little sense. It saves Avast a lot of trouble to create and support a separate app as they’re offering a không lấy phí service and are looking for ways lớn cut corners.

Mobile apps

mobile apps are a tricky area. More often than not, the Android and iOS versions are like night & day. This is because there’s little need for antivi khuẩn software if you’re using an iOS device. Apple keeps a tight grip on their App Store, and there are many restrictions to sideload your apps if you’re not using an unlocked device. So, few antivirut providers invest time to make third-buổi tiệc nhỏ software solutions lớn remove sầu malware from a device in which it would be very hard khổng lồ find malware.


Consequently, Bitdefender and Avast both have sầu quite lacking iOS versions. Bitdefender phầm mềm only has browser protection, a VPN, and an trương mục privacy monitor. That’s only a few features when compared lớn their desktop counterpart. Avast iOS version has a VPN, web protection. There’s also an exclusive sầu photo lớn vault in which you can store your embarrassing photos. However, that’s hardly a better suite.


When we turn to Android, the number of features double. Bitdefender’s phầm mềm has everything that the iOS version did, plus a malware scanner, anti-theft tools, và ứng dụng loông xã. That’s a significant amount of useful features. Avast, on the other hvà, has RAM boosting, device tracking and protects against malicious websites. Sadly, a malware scanner isn’t available.

In short, if you’re using an iOS device, there’s no point in getting either application. On Android, however, Bitdefender does a much better job & offer more features.

Customer support

Email✔ (with paid plans)
Live chat✔ (with paid plans)

All the services that offer miễn phí versions have one comtháng flaw – they all laông xã customer support options. A statement that is very true for Avast và not at all true for Bitdefender.

The most amazing thing about Bitdefender’s customer support is that it’s available even if you’re a không tính phí user. This might not sound like much, but it includes live sầu chat, you can tương tác them via phone or email. Suppose it’s a minor issue & you prefer solving problems on your own. In that case, you can find FAQs, guides, và other information on their support website.

As far as Avast are concerned, if you’re on a không tính tiền version, your problems become worthy of their attention only when you become a paying user. Even when you bite the bullet và become their subscriber, this changes very little when it comes khổng lồ tư vấn. Primarily, Avast relies on phone lines & their customer tư vấn portal with many FAQs and guides.

Bitdefender just offers more ways how it can offer tư vấn, & it’s generally a more welcoming service. When it comes lớn customer support, this service truly deserves praise.
