Editor's disclosure: We stand with Ukraine and support sanctions on Russia. In line with these concerns, Bloomberg reports that Kaspersky Lab has ties to the Federal Security Service (FSB) and was sharing customer data. Cybernews does not tolerate the bloodshed, human rights abuses, and alleged Geneva Conventions violations the Russian army has inflicted on the Ukrainian people. As a result, we will no longer endorse Kaspersky products or support companies that may aid these actions.

Kaspersky vs Bitdefender: which offers better protection?

Getting the results of our Kaspersky vs Bitdefender comparison involves conducting in-house antivirus tests and consulting third-party labs, such as AV-TEST and AV-Comparatives. Using these various findings, we can better understand which antivirus service delivers consistent results and is overall better.

	Bitdefender	Kaspersky
AV-TEST	Top product	Top product
AV-Comparatives	Advanced+	Advanced+

The results from various third-party test labs show that Bitdefender and Kaspersky are in the same top-tier category regarding antivirus effectiveness. Both garnered perfect scores in the latest evaluations.

According to the most recent AV-TEST Institute results, both Bitdefender and Kaspersky have the maximum scores in the protection, performance, and usability categories. Thus, they earned top product certificates. Bitdefender’s score has minimally fluctuated over the years, while Kaspersky's performance has remained the same. Additionally, the scores were identical across all tested platforms, including Windows, macOS, and Android. Notably, the score remained perfect for both products on macOS and Android over the years. Therefore, it's fair to conclude that you will get the highest caliber of malware protection based on this data.

According to AV-Comparatives tests, Bitdefender received a 99.1% protection rate, while Kaspersky received a slightly higher 99.5% protection rate. Compared to previous test results, Kaspersky’s result has increased, while Bitdefender’s has fluctuated.

In conclusion, various independent labs confirm that Bitdefender and Kaspersky are equal in effectiveness.

Malware protection

Both Bitdefender and Kaspersky Antivirus can prevent malware from ever landing on your device. If you go with the paid versions, both tools include real-time monitoring. That means even downloading a malicious file won't be easy to pull off.

Bitdefender uses a global website reputation database to conclude whether the link you're about to open is dangerous. Kaspersky does the same but relies on different databases and potentially uses different algorithms, so your experience might be slightly different.

Regarding system protection, Bitdefender and Kaspersky use machine learning to capture zero-day malware. Bitdefender has the Shield feature, and Kaspersky has a System Watcher to scan your system logs to detect suspicious activity. This is a high level of protection against various cyberthreats.

Both providers performed very well in our in-house tests, with Bitdefender detecting 132 out of 150 malware samples we planted on the device, and Kaspersky detecting all malware samples, with just 3 false positives.

Scanning

Both Kaspersky and Bitdefender provide plenty of options to scan your device for malicious software.

Kaspersky offers several methods to scan your PC, depending on how much time you have and what you expect to find. First, there's Quick Scan, which checks all the places where malware is usually found. In our tests, this scan took 4 minutes and 15 seconds but failed to detect any malware. If it detects any malware, it prompts to do a Full Scan. The tool always cross-checks the scan results with the most up-to-date malware databases, so you always get accurate results.

The Full Scan scan took 53 minutes, scanning 369,211 files and detecting all malware samples. However, once the scan was 99% complete, it showed that it would take less than a minute, but it actually took more than 20 minutes.

Bitdefender also offers multiple scanning options (Quick Scan, System Scan, Rescue Environment, Custom Scans). We focused on quick and deep scans during our tests, as consumers most frequently use these. The quick option took almost 4 minutes to complete, but it failed to find any malware samples. Meanwhile, System Scan took almost 35 minutes to scan about 583,501 files and successfully detected 80% of the malicious samples we placed.

Firewall protection

Most premium antivirus services add a firewall. It's one of the most critical components of your device's security. It supervises all incoming and outgoing connections and controls what programs can access the local area network.

Kaspersky allows you to modify your network properties in great detail. You can allow or deny connections from random ports, block particular connections, and set connection rules per application. If you know what you're doing, there's an opportunity to seal the gaps that malicious hackers could exploit.

Bitdefender allows you to tweak application access, rules, and network adapter settings. There's even port scan protection, which shuts down anyone looking for loopholes in your network.

Pricing and plans

Bitdefender and Kaspersky offer plans suited to different needs. However, if you only need basic protection, Bitdefender's starting price is much lower, at $12.99/year, compared to Kaspersky’s $38.49/year. Overall, Bitdefender is a more affordable option than Kaspersky.

Plan	Bitdefender	Kaspersky
Free	$0.00	$0.00
Antivirus Plus/Standard	$12.99/year	$38.49/year
Premium Security/Plus	$42.49/year	$52.99/year
Total Security/Premium	$19.99/year	$74.99/year
	Check pricing	Check pricing

Bitdefender’s $12.99/year starting price is lower than Kaspersky’s $38.49/year introductory cost. Additionally, Bitdefender includes more features overall, making it the more worthwhile option of the two.

Naturally, the two providers also offer pricier plans for covering customers with more significant security needs. Whichever tier you choose, Bitdefender is the cheaper choice.

Try Bitdefender's features

You don’t have to look deep for similarities between these services. For example, Bitdefender’s Advanced Threat Defense uses real-time monitoring with its proprietary Global Protective Network. Likewise, Kaspersky’s model is equivalent: Kaspersky Security Cloud also offers adaptive monitoring. So, whichever service you choose, you will get similar approaches to malware removal.

Ransomware protection is another crucial feature nowadays. Both Bitdefender and Kaspersky include anti-ransomware tools, though they are implemented 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 and detects ransomware patterns to stop malware.

As for network security, both providers add firewalls and other network shields. Bitdefender offers public Wi-Fi profiles and a Wi-Fi security advisor. Both features are designed to increase your device protection when you’re connected to public hotspots. Kaspersky antivirus includes a firewall, but it's only available on its Total Security plan.

Bitdefender has an exclusive feature called the Rescue Environment. It lets you scan your hard drive when your operating system hasn’t booted. It can remove malware that has penetrated deep into the system files. Kaspersky offers a similar feature but doesn’t include it in the antivirus suite.

Additional tools

Regarding additional features, both Bitdefender and Kaspersky offer anti-tracker tools, a VPN, file shredders, password managers, and anti-theft tools.

	Bitdefender	Kaspersky
Anti-tracker	✅ Yes	✅ Yes
Additional browser	✅ Yes	✅ Yes
VPN	✅ Yes	✅ Yes
File shredder	✅ Yes	✅ Yes
Optimization tool	✅ Yes	✅ Yes
Anti-theft tools	✅ Yes	✅ Yes
Adjustable profiles	✅ Yes	❌ No
Password manager	✅ Yes	✅ Yes
Anti-spam	✅ Yes	✅ Yes
Parental controls	✅ Yes	✅ Yes
Privacy cleaner	❌ No	✅ Yes

There are some feature differences to consider, too. One 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 to your activity. So, if you’re working or gaming and need more resources allocated to the current task, you can toggle the matching profile. This will tell Bitdefender not to bother you with pop-ups and 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 and want to pass it to someone else, this will be a handy tool to eliminate traces of your details.

Apps and interface: which is more user-friendly?

Bitdefender and Kaspersky are on par regarding device compatibility. Both are compatible with the main desktop and mobile operating systems (Windows, macOS, Android, iOS) and can protect multiple devices simultaneously. However, details will vary based on the subscription plan you choose.

I liked Bitdefender's download procedure because I didn't have to be a registered user to get the free version. Both providers' installation processes are similar. You need to download an installer, which installs and downloads all necessary files simultaneously.

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

Bitdefender seems more neatly organized, with a sidebar where you can find the settings you're looking for according to 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 easier to pick up.

Desktop apps

One of the desktop features is using Bitdefender and Kaspersky's scanner independently from the antivirus itself. Both are free and intended to be used as a barebones version of the entire 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. As with most antivirus apps, the macOS version is more basic than Windows. This is due to Apple’s infrastructure, which limits certain features.

For example, with Kaspersky on macOS, you can tweak or toggle various parameters like the file antivirus and web attack blocker, update outdated apps, and enter the children-safe mode. In addition, macOS Bitdefender allows you to add folders to the watch list to prevent ransomware, add Time Machine protection, block adware, and block phishing sites.

With Windows, you can unlock more features, depending on which subscription plan you choose.

As for the apps themselves, both providers are shooting for a visually appealing user interface that 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.

Both antivirus programs offer tools beyond malware protection. You will get password managers, private browsers, and cleanup tools. This provides additional value and helps you justify the purchase.

Mobile apps

Kaspersky’s iOS app is more limited compared to its desktop version, which is typical for iOS antivirus apps due to strict operating system restrictions.

Nonetheless, Kaspersky offers a vulnerability scanner, a VPN, an anti-phishing tool, a data leak checker, and a password manager.

On iOS, Bitdefender is similar to Kaspersky in terms of offerings. It also includes a password manager, data breach alerts, blocking of suspicious sites, and VPN encryption.

The Android apps are more feature-rich. For example, Kaspersky's Android app can scan for malware, includes real-time protection and an app lock, and has a call filter. There are even such exclusives as safe messaging, which protects you from malicious links sent via text messages. The anti-theft feature helps you to locate your missing device, alert it, or erase its data.

As for Bitdefender, it scans for malware, blocks malicious links, protects your device with anti-theft tools, and offers a VPN. There are more exciting additions, like WearON, which allows phone tracking from your smartwatch. You can ring your phone to find it or get alerts once your phone gets too far from your watch. Plus, it includes extra features like App Anomaly Detection, Scam Alert, and App Lock.

Overall, Bitdefender offers more unique features across different platforms compared to Kaspersky.

Impact on PC performance

As with any antivirus, it’s nice if it consumes fewer system resources, leaving you more room to complete other tasks. Since both Bitdefender and Kaspersky can schedule background scans, the CPU consumption may increase at times, which could ruin your experience, especially if you have an older laptop.

However, when we look at the results, it seems that these services put a different level of load on your system. Kaspersky seems to be more CPU-intensive. During a full scan, Kaspersky used 80-100% of my CPU, while Bitdefender only needed 50-75%.

As for RAM, Kaspersky used 54-58% of available 8GB RAM, while Bitdefender needed only 39-45%. So, Bitdefender is a clear winner when it comes to system resources.

Customer support

Bitdefender and Kaspersky have dedicated knowledge bases. Both cover a wide variety of topics that will be helpful to both beginners and advanced users. You'll find helpful guides and answers to the most frequently asked questions.

	Bitdefender	Kaspersky
Email	✅ Yes	✅ Yes
Live chat	✅ Yes	✅ Yes
Phone	✅ Yes	✅ Yes
Knowledge base	✅ Yes	✅ Yes

Kaspersky offers email, chat, phone, and remote assistance if you need to contact a human. All of them are available 24/7, but remote assistance is only available to premium users.

Bitdefender uses the same channels for customer support. It also offers phone, email, and live chat support. Bitdefender's Expert Community is a great resource for quick help. Plus, there’s a remote assistance option, but it's reserved for more complex tasks.

While both providers offer similar support options, Bitdefender’s community forum is a huge perk. This is a massive addition and allows you to save time, skipping waiting queues to get an answer someone else has already found.
