AV-TestTop productTop product

Comparing malware removal capabilities is no walk in the park. There are many things khổng lồ consider besides malware detection rates. This includes false positives & effectiveness levels against zero-day threats.

According lớn the most recent AV-TEST Institute results, both Bitdefender và Kaspersky have the maximum scores và have received vị trí cao nhất product certificates. Additionally, the scores were identical across all tested platforms, including Windows, macOS, & Android. Therefore, it"s fair to lớn conclude that you will be getting malware protection of the highest caliber based on this data.

Another independent malware testing lab, AV-Comparatives, found some differences. While they got a 99.9% protection rate with Bitdefender, Kaspersky only managed 99.5%. This isn"t a tremendous difference, but it still means that out of 736 test cases, four viruses got through. In turn, Bitdefender was awarded the Advanced+ rating, while Kaspersky only earned Advanced.

I also looked at the SE Labs scores only to lớn find that both providers got the highest marks. This isn"t surprising as most antiviruses get a AAA evaluation from SE Labs.

In conclusion, Bitdefender wins, but this victory hangs by a thread. Both tools are among the very best, and I wouldn"t be surprised lớn see Kaspersky ahead in the following monthly recap.


Malware protection

Both Bitdefender và Kaspersky Anti-Virus have means lớn prevent malware from ever landing on your device. If you go with the paid versions, both tools include real-time monitoring. That means that even downloading a malicious tệp tin won"t be that easy to lớn pull off.

Bitdefender uses a global trang web reputation database to conclude whether the links you"re about to xuất hiện is dangerous. Kaspersky does the same, but it relies on different databases và potentially uses different algorithms (so your experience might be a bit different).

When it comes lớn your system protection, both providers also use machine learning to lớn capture zero-day malware. They just gọi it differently. Bitdefender has Shield and Kaspersky has System Watcher to scan your system logs to detect suspicious activity. This is a high cấp độ of protection against the garden variety of cyber threats.


Scanners are an antivirus service"s bread and butter. So naturally, both Kaspersky & Bitdefender will provide you with plenty of options to lớn turn over your hard drive lớn find parasites.


Kaspersky offers several methods lớn scan your PC, depending on how much time you have & what you expect lớn find. First, there"s Quick Scan to kiểm tra all the places where the malware is usually found. If it detects something, it prompts the Full Scan. The tool always cross-checks the scan results with the most up-to-date malware databases so you always get accurate results.

Bitdefender also offers multiple scanning options. For example, you can scan for threats & outdated applications that could be exploited. After each scan, you will be given a chart with how many threats have been found and how many of them were quarantined. Other potentially concerning results will be only shown, leaving you the option to lớn decide what you want to vì chưng with them.

Firewall protection

Most premium antivirus services also địa chỉ cửa hàng a Firewall. It"s one of the most important components of your device"s security. It supervises all incoming & outgoing connections và controls what programs have access lớn the local area network.

Kaspersky allows you khổng lồ modify your network properties in great detail. You can allow or deny connections from random ports, block particular connections, phối connection rules per application, và more. If you know what you"re doing, there"s an opportunity lớn seal the gaps that hackers could exploit.

While Bitdefender closely follows Kaspersky, in this particular area, they have fewer customization sliders. Though, you"re still able lớn tweak application access, rules, và network adapter settings. There"s even port scan protection which shuts down anyone who tries to lớn look for loopholes in your network.

Features overview

While most of Bitdefender’s opponents would have already been knocked out, Kaspersky goes blow for blow. In total, Bitdefender has slightly more features, which is enough to give it a narrow edge over Kaspersky. Yet the lead is so slim that it could easily be overturned in the next patch.

As it stands now, Bitdefender remains the ultimate champion in this category.


Security features

Ransomware protection✔️✔️
Safe browsing✔️✔️
Webcam/microphone protection✔️✔️
Rescue Environment✔️

You don’t have to look deep for similarities between these services. For example, Bitdefender’s Advanced Threat Defense uses real-time monitoring with their proprietary Global Protective Network. Likewise, Kaspersky’s mã sản phẩm is equivalent: Kaspersky Security Cloud also offers adaptive monitoring. So, whichever service you end up choosing, you will be getting similar approaches lớn malware removal.

Ransomware protection is another hot feature nowadays. Both Bitdefender và Kaspersky include anti-ransomware tools, though they are implemented a bit differently. Bitdefender has a Ransomware mitigation feature that creates backups of your files in case your PC becomes infected. Meanwhile, Kaspersky offers a decryption function for your encrypted files và detects ransomware patterns khổng lồ stop malware in its tracks.

As for network security, both providers showroom Firewall & other network shields lớn their suite. In addition, Bitdefender offers public wifi profiles and a wifi security advisor. Both are designed to lớn increase your device protection when you’re connected to public hotspots or want khổng lồ make sure that your Firewall is up lớn snuff. Finally, Kaspersky Anti-Virus also includes Firewall, but it"s only available on their Total Security plan.

An exclusive feature that Bitdefender has is the Rescue environment. It allows you lớn scan your hard drive when your operating system hasn’t booted. It will enable you to remove malware types that have penetrated deep into the system files. Kaspersky offers this feature separately and doesn’t include it in the antivirus suite.

Additional tools

In terms of additional features, both providers offer anti-tracker tools, a VPN, file shredders, password managers, và anti-theft tools. You"s be hard-pressed to lớn find two services that are more alike.

There are some feature differences lớn consider, too. One of them is Profiles, which is only included in Bitdefender’s antivirus suite. This is a very convenient addition as you can modify your resource usage according khổng lồ your activity. So if you’re working or gaming & need more resources allocated khổng lồ the task at hand, you can toggle the matching profile. This will tell Bitdefender to not bother you with pop-ups và use less processing power. There’s no equivalent on Kaspersky.

The only thing that Kaspersky has over Bitdefender is a privacy cleaner. It deletes traces of your activity on the device. So, if you’ve used a device & want khổng lồ pass it to lớn someone else, this will be a handy tool lớn get rid of traces of your details.

Impact on PC performance

"Lightweight" doesn"t necessarily mean "consumes little system resources." For this reason, I fired up both antiviruses and checked how much of my system resources they use. The bigger the load on the CPU, the less room for there is for other tasks. Since antiviruses are known for scheduling background scans, this can ruin your experience, especially if you have an older laptop.

Bitdefender performance impact

Though when we look at the results, it seems that these services put a different level of load on your system. Bitdefender seems khổng lồ be more CPU-intensive. During a full scan, it used 66% of my CPU, while Kaspersky only needed 32%. That"s almost half the usage.

Kaspersky performance impact

The same story repeated with memory. Kaspersky used only 16% out of my available 16 GB of RAM, while Bitdefender needed 38%. This draws two different usage scenarios – if you"re using a really slow và old device, Kaspersky will be a better fit. Bitdefender can be taxing on such systems. It could be argued that it pays off, as it has slightly better malware removal statistics.

Pricing and plans

Let"s start this section with a reminder that both of them can be had absolutely for free. Bitdefender & Kaspersky offer the best không lấy phí antivirus versions on the market. Of course, they are limited, but if you just want khổng lồ get rid of malware, both will suit you just fine.

Antivirus Plus/Anti-Virus$23.99/year$29.99/year
Internet Security$32.00/year$39.99/year
Total Security$36.00/year$49.99/year
Check PricingCheck Pricing

One way to lớn look at Kaspersky"s pricing is by adding ~$10 on top of Bitdefender"s price. Surely, that"s an oversimplification, but it"s one way to lớn say that Kaspersky is more expensive across the board. When you factor in that overall, you"re getting slightly fewer features, the package looks less appealing.

So, suppose you"re very budget-cautious and are looking for a better deal. In that case, Bitdefender will deliver a more well-rounded package và for a lower price.



I liked Bitdefender"s tải về procedure because I didn"t have to lớn be a registered user to get the không tính phí version. The installation procedure was pretty simple, too. You"re asked to download the installer, which then fetches all the other necessary files through the client. So, you"re installing and downloading at the same time. Kaspersky uses an identical system, so there"s no difference between the competitors in this sense.

As for the apps, while both providers use different màu sắc schemes & have different UI outlines, both will be intuitive for most users. Kaspersky shows everything on one main screen, & if you need advanced options, you can expand the menu to find what you need.

Bitdefender seems more neatly organized with a side bar where you can find the settings you"re looking for according khổng lồ particular categories. I think it"s a more straightforward solution and might be less confusing than expandable lists. The service also has a user"s guide built into the software, making it even easier khổng lồ pick up.

Desktop apps

One of the desktop features is using Bitdefender & Kaspersky"s scanner independently from the antivirus itself. Both are miễn phí and intended to be used as a barebones version of the full suite. This will be appreciated by users who just want to have a quick scan.


The apps themselves will depend the most on your operating system. Obviously, macOS users, as usual, will get the inferior package when compared to what the Windows crowd are getting. It doesn"t really matter how high you"ll climb with the pricing tiers.


For example, with Kaspersky on macOS, you can tweak or toggle various parameters like the tệp tin antivirus, web attack blocker, update outdated apps, & enter the children-safe mode. In addition, macOS Bitdefender allows you to địa chỉ cửa hàng folders lớn the watch list to prevent ransomware, add time machine protection, block adware, & block phishing sites.

With Windows, you will be getting the entire suite, & both services don"t hold anything back. The only limiting factor there is your subscription plan.

As for the apps themselves, both providers are shooting for visually appealing UI, which wouldn"t confuse even novice users. You"ll be able to find most features with a couple of clicks. Other important information like protection status is also indicated with colors.

What also can be considered both antiviruses strengths is that they go out their way to lớn offer tools beyond malware protection. You will be getting password managers, private browsers, and cleanup tools. This provides additional value và helps you khổng lồ justify a purchase.

Mobile apps

If you"re an hãng apple user, you"ll be sad lớn hear Kaspersky doesn"t have an antivirus tiện ích for iOS. That is because, in Apple"s words, they"ve created game ios with security built-in. This isn"t false, most of the system processes are locked away from app và user access, & the app Store is under strict supervision. In turn, few viruses can bởi damage there. However, Kaspersky does offer Security Cloud và VPN, which technically is a separate service from their antivirus offerings. You can check whether your data has appeared in data leaks, use the VPN, manage your credentials with the password manager, and block phishing links.

On iOS, Bitdefender isn"t that much different from Kaspersky in terms of offerings. It also includes a password manager, data breach alerts, blocks suspicious sites, & can encrypt your connection with a VPN.


Where the antivirus part becomes true again is on Android. The suites have much more features and are overall more helpful. For example, Kaspersky"s apk app can scan for malware, includes real-time protection, an app lock, and has a hotline filter. There are even such exclusives as SMS phishing filters. It protects you from malicious liên kết sent to you via text messages. The anti-theft is also there, allowing you lớn locate your missing device, alert it or wipe its data.


Bitdefender follows suit matching most of their offerings. So naturally, you can scan for malware, block malicious links, protect your device with anti-theft tools, and use a VPN. Though there are more exciting additions as well, like WearON – it allows phone tracking from your smart wearable. So if you don"t know where you put your phone, you can ring it from your watch. You also get an alert if your phone gets too far from your watch.

Bitdefender once again has the ace in the hole and can surprise its users with unique features. As good as it may be on its own, Kaspersky gets beat by the slightest of margins here.

Customer support

Live chat✔️✔️
Knowledge base✔️✔️

Both antivirus providers have dedicated knowledge bases. In both cases they cover a huge variety of topics which will be useful to lớn power users và those, who are just starting. You"ll find helpful guides và answers khổng lồ the most frequently asked questions.

Kaspersky offers email, chat, phone, and remote assistance if you need to lớn reach out to a human. All of them are available 24/7, with the caveat being that remote assistance is only reserved to lớn premium users.

Bitdefender uses the same channels for customer support. They also have phone numbers, thư điện tử support, and live chat. However, the bonus is that they include Bitdefender"s Expert Community. There"s also a remote assistance option, but it"s reserved for more complex tasks.

Even though both services are evenly-matched, I have to lớn give credit where it"s due khổng lồ Bitdefender. Since they"re also running a community forum, you can Google most issues related & unrelated khổng lồ Bitdefender there. This is a massive addition & allows you to lớn save time, skipping waiting queues khổng lồ get an answer that someone else has already found.
