This matchup is worthy of being called the battle of the titans. Bitdefender is often considered the best antivi khuẩn service. Then, there"s Avast, a company so large it eats smaller cybersec providers for breakfast, incorporating them into their infrastructure. Both providers have không tính phí versions, both are well known for their products. The question remains: which one reigns triumphant?

So, in this Bitdefender vs. Avast comparison, I"ll look at each provider"s strengths và weaknesses in categories lượt thích features, malware protection, pricing, apps, and customer support. After this short read, you"ll have sầu a much better idea of which one is better and why.

Bitdefender vs. Avast: which offers better protection?

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

According lớn AV-TEST Institute"s data, when it comes lớn protection, both Avast and Bitdefender score 6 points on Windows & 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 feature danh sách, which puts it over the edge.


Malware protection

Avast"s capabilities to 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 giảm giá khuyến mãi with will be significantly lower because most of the junk won"t over up on your device. It won"t pass the web countermeasures.


To some extent, the same applies to lớn 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 antivirut 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 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, and 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 sầu network security toolkits. My impression is that Avast spent too much time khổng lồ make their Network protection interface to lớn look pretty & 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 to lớn go overboard, so make sure you"re not messing with the ports your household members are using.


Bitdefender doesn"t have sầu anything spectacular when it comes to lớn firewall customization either. Regardless, the whole feature offers detailed information and works in the background. You can just mix it up & forget till you get a notification that you"re trying to access a suspicious connection. Overall, Bitdefender"s firewall is a bit more functional & 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 antivirut 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-platkhung support, Avast is somewhat better at bringing the feature to Apple devices. However, Windows is most in need of antivirut software, therefore, I consider those features more important.


Shared features

Let’s explore the features that both Bitdefender and 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 home 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 and Avast offer ransomware protection. When it comes khổng lồ Bitdefender, the program also makes copies of your most important files with a possibility to restore them in case you’d become a victlặng 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 và 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 & 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-track tool in its Premium plan.


If you occasionally need to lớn 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 & Avast offer a tệp tin shredder. It’s a tool that allows you to lớn delete files without the possibility to lớn recover them. Very useful in cases when you work with large volumes of someone’s private data.

An essential feature nowadays, webcam and microphone protection is offered by both Avast and Bitdefender. It denies all suspicious requests khổng lồ your camera or microphone. That way, you can know for sure that no one is listening khổng lồ 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 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 and trackers.

Unique features

After looking at the table that displays chất lượng 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 feature because you can’t remove sầu some rootkits when you’re booted inlớn the system, which is where you perform most of your system scans

Next, Bitdefender detects what you’re doing with your device khổng lồ toggle particular modes in order not to lớn 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 email filter compatible with most popular mailboxes. Using it, you can set up spam filters khổng lồ filter out unwanted emails.

If you need to lớn, you can also make use of Bitdefender’s parental controls. This feature lets you mix up smart device limits and control how the device can be used & which webpages are available. If you want the parental controls tool with Avast, you have to lớn get a totally separate app, 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 tiện ích, you can run it in an isolated sandbox to determine whether it’s safe. It won’t spread to other system files, so it’s a convenient method to lớn check up.

Impact on PC performance

When you look at the amount of bloatware that Avast tries 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 lớn vị with their smart protệp tin management, so when it"s in full background kiểm tra mode, you might be away from your system. This antivi khuẩn adapts to lớn you, not the other way around.


If someone says it"s impossible lớn get a good service for không lấy 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/Avast One$23.99/year$50.28/year
Total Security/Premium Security$36.00/year$69.48/year
Cheông chồng PricingCheông xã Pricing

From this perspective sầu, Avast just looks bad. Their miễn phí 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 to 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.
