Bitdefender review 2024

Bitdefender is one of the top-rated antivirus providers on the market in 2024. It continuously gives excellent results at independent lab tests, isn’t as expensive as its competitors, and includes useful security features.

Bitdefender uses a cloud-based engine, and during my testing, the scans were more efficient and not as resource-intensive as other antivirus providers. Its paid plans include additional tools like a VPN, password manager, web protection, and more.

Although Bitdefender offers many excellent features, there’s still room to grow. Most of the available tools are great and efficient, but, for example, the VPN is limited to 200MB of data per device unless you upgrade to the Premium Security Plan. Plus, features like web protection could be more effective.

To help you make an informed decision, this Bitdefender review 2024 explores its features, protection capabilities, reviews different plans for all budgets, and compares Bitdefender to its rivals.

Bitdefender review: key takeaways

Bitdefender is a market-leading antivirus tool offering excellent threat prevention and protection. It provides top-notch security, performance, and usability for a broad range of users – from consumers and small businesses to enterprises. Here is an overview of the main points discussed in this review:

  • Pricing. Bitdefender offers affordable prices, varying subscription plans, a 30-day money-back guarantee, and even a free plan. The Antivirus Plus plan starts at start at $29.99/year and can be installed on 1 device.
  • Security features. Bitdefender comes with many effective features to keep your devices intact. The primary tools include a firewall, malware scanner, ransomware remediation, a VPN, and a password manager.
  • Ease of use. While Bitdefender can be a hassle to install, the software is lightweight and straightforward, meaning you shouldn’t encounter significant usability issues after setup.
  • Performance impact. I evaluated how Bitdefender impacts the device while performing scans and other tasks, and the overall results were more than satisfactory.

Bitdefender price

Bitdefender offers 4 different plans: Free, Antivirus Plus ($29.99/year), Internet Security ($42.49/year), and Total Security ($49.99/year). Although the premium package cost is on a higher scale, each plan offers a wide variety of useful safety features to ensure the best security for your devices.

The best pick for those who need apps available on all available operating systems is Total Security.

Bitdefender offers 30-day free trials for all paid plans and a 30-day money-back guarantee on top, as a warranty against buyer’s remorse.

While the Bitdefender antivirus free plan covers the basics of your device security, with the premium subscription plans, you’ll receive the needed additional features. Some of those are a VPN, password manager, and webcam and microphone protection.

Bitdefender Antivirus Plus

This is a Windows-only entry plan to protect 3 of your devices from malware. With Antivirus Plus, you’ll get features like:

  • Malware scanner
  • Secure browser
  • VPN (capped at 200 MB of data daily)
  • Password manager
  • Anti-tracker
  • File-shredder
  • 24/7 customer support

On the other hand, there will be security limitations. You won’t get Bitdefender firewall protection or system optimization tools, for example. Also, remember that renewal prices may be higher than the purchase price.

Bitdefender Internet Security

Bitdefender Internet Security is an upgrade from Antivirus Plus since this plan adds these features:

  • Firewall protection
  • Anti-spam feature
  • Parental controls
  • Webcam and microphone protection

The price for the features included is more than fair, and you’ll receive the best security and protection for your Windows device while searching online. The drawback might be that it covers only 3 devices and only Windows users.

Bitdefender Total Security

Bitdefender Total Security doesn’t expand too much on the features side – the only addition to all the Internet Security features are:

  • System tune-up tools
  • Anti-theft protection

However, this plan covers mobile devices, so you get to protect your Android and iOS phones, as well as macOS devices, with one of the best antivirus software on the market.

Total Security plan also ups the number of devices that you can cover with one subscription up to 5.

Does Bitdefender have a free version?

Yes, Bitdefender has a free plan option for both Windows and macOS users. The Mac version provides you with the most basic protection. With the Virus scan feature, you’ll get the on-demand scanner for malware and nothing else.

Meanwhile, the free version of Bitdefender is a more comprehensive anti-malware protection suite with nice bonus features.

As a matter of fact, the Bitdefender Free Edition is comparable to the paid premium versions of some other antivirus service providers. It offers solid security for your device with a virus scan and real-time protection features. Additionally, you’ll be secured from phishing and ransomware attacks.

With that said, Bitdefender does leave a lot out as well, including network threat protection, usage profiles, a VPN, a password manager, and much more. So if they are a dealbreaker for you, then consider investing in the Bitdefender premium subscription. They not only offer the highest level of security but also cover multiple devices with one account.

Is Bitdefender safe?

Yes, Bitdefender is a safe anti-malware application. Actually, it's one of the safest antivirus software on the market. It even got the AV-Comparatives' Outstanding Product Award and reached the highest Advanced+ rating in all seven tests of the Consumer Main-Test Series.

Awards aside, let's take a look at the most recent Bitdefender virus detection rates. According to the latest AV-Test, Bitdefender blocked 100% of threats during the testing period of November-December 2023. This included both 0-day and 4-week-old malware and other threats.

Bitdefender AV-Test protection 2023

The Real-World Testing (0-day) was done on 210 samples, while the AV-TEST reference set (4-week) test used over 11,800 malware samples. The excellent outcome resulted in getting a Top Product certificate with a maximum points of 6 in each category – protection, performance, and usability.

bitdefender av test results 2023 december

During in-house tests, Bitdefender blocked all 10 of the threats I challenged it with. The quick scan took only 2 minutes, while the full one – 14 minutes.

With these results, you can be confident Bitdefender will eliminate any threat to your device. That is exactly why Bitdefender is considered one of the best and safest antiviruses for protecting your device from malware.

Top-rated antivirus software
Bitdefender ensures your device and data protection with excellent malware detection and removal rates. In addition, this antivirus has an excellent tool to protect your device from different online threats, optimize your device performance, and secure your sensitive data.
cybernews® score
4.9 /5

Bitdefender offers top-class protection for an approachable price point. It has a variety of security features and tools to optimize your device performance.

Bitdefender security features

Regarding Bitdefender free vs paid, the software employs the same malware database to identify potential threats. So, regardless of your budget, you'll get the same excellent level of malware removal. However, there are additional subscription benefits to consider.

Here is a list of some of the most impressive features included in the Bitdefender antivirus package:

FeatureWhat it does
FirewallAllows you to monitor all the connections from your device
Anti-theftAllows you to locate your device on Google Maps, lock your device remotely
Malware scannerOffers different scanning options from quick to a thorough search for threats in your device system
Real-time protectionCatches threats in real time before they enter your system
Anti-trackerProtects you from online trackers that harvest your data
VPNA tool for digital protection and data collection prevention
Password managerKeeps all your passwords safe and in one place


Bitdefender Firewall is a security feature that protects your device from unauthorized access. It does this by blocking inbound and outbound connections, both on local networks and on the internet. The firewall uses a set of rules to determine which connections to allow and which to block. These rules are automatically created for known, legitimate applications. You can also manually create rules for applications that you trust.

bitdefender firewall

This feature can be used to protect your computer from a variety of threats, including hackers, malware, and data snoops.

After testing the Firewall feature hands-on on Windows, I received popup boxes to allow or block applications. I could configure and monitor all the permissions of known and unknown programs.


Anti-theft is a security feature that helps you to protect your lost or stolen device. I find it very useful in this day and age where you have to be extra careful with your belongings. The feature includes a variety of functionalities, such as:

  • Remote location. Locate your device on a map, even if it is turned off.
  • Remote lock. You can remotely lock your device, preventing anyone from accessing your data.
  • Remote wipe. Remotely wipe your device, deleting all of your data.
  • Remote alarm. Remotely activate an alarm on your device, making it easy to find if it is lost or stolen.
  • SIM card change alerts. Receive alerts if your SIM card is changed, which can help you to track your device if it is stolen.
  • Photo capture. If someone enters your device's PIN or password incorrectly three times, Bitdefender Anti-theft will take a photo of them using the front camera.

Malware scanner

Bitdefender has an efficient and reliable virus scanner. It’s based on malware directory and machine learning, so it’s especially effective in detecting both known and unknown malware threats. The scans happen in the cloud, therefore there’s a minimal impact on the device system.

100% reliable virus scanning

Bitdefender offers various virus scan options that ensure excellent protection from malware threats. You can scan certain folders, your entire device, or look for vulnerabilities to improve your device protection.

Get Bitdefender

There are four scan types for you to choose from – Quick scan, System scan, Vulnerability scan, and Custom scan.

To test the scan options (Quick and System scans), I’ve downloaded 10 malware samples (those include trojans, red line stealers, worms, ransomware, etc.) and disabled the real-time protection feature. After that, I tested the Quick and System scans together with computer resources monitoring to see how successful Bitdefender’s scans are and how much they affect the device system, and these were the results:

  • Quick scan – scans those device locations where malware usually appears. It took 3 min 37s to complete and scanned almost 4000 files.
  • System scan – scans the entire system for malware threats. This scan took 24 min 05s and scanned more than 163,000 files. It managed to catch 9 out of 10 zero-day threats, so this scan type provides truly reliable protection for your device. Overall, the system scan took under 1 hour – these results are competing with other leading antivirus like Norton or Avira, which took on average 15 minutes to complete.

Additionally, Bitdefender offers two other scan options:

  • Vulnerability scan – checks the device for any vulnerabilities. This scan takes 5 minutes and includes checking for weak passwords, outdated applications or drives, and Windows updates. This is especially useful if you don't update your device manually. It also detects any system changes and informs about them, in case there's been a security breach and additional measures that need to be taken.
  • Custom scan – this option allows you to only scan specific system locations where a threat may be. Additionally, it allows you to schedule your scans. Bitdefender’s competitors, like Norton or TotalAV, also provide quick custom scans that you can easily schedule within a few clicks.

Overall, the Bitdefender malware scanner is one of the best security tools. It’s fast, thorough, and doesn’t slow down your device, so you can be certain of your system security.

Real-time protection

Bitdefender’s real-time protection feature is also known as Bitdefender Shield. This security feature is constantly scanning all of the downloaded files for threats. If a threat is caught, then it’s deleted or placed in quarantine. So, real-time protection can catch malware before you get to open the malicious files.


This feature is really effective in offering you the best protection since it works closely with Bitdefender's Global Protective Network, which monitors more than 500 million machines to extract new malware models. That’s how this feature can ensure that you’re protected against very recent or poorly documented threats and phishing attacks.

I’ve put Bitdefender’s malware scanner to the test to see just how reliable it is. After downloading 10 malware files, I unzipped them and allowed the real-time protection to do its thing. Usually, it catches the threats really quickly and deletes most of the malicious files that have been unzipped.

Bitdefender's real-time protection feature cannot scan compressed files, so for it to be effective, you’ll have to unzip the downloaded files. Otherwise, this is a quick and highly secure feature that protects your device from new and already-known cyber threats.

Ransomware remediation

Bitdefender’s ransomware remediation feature is designed to protect your files from ransomware threats automatically. This feature creates a backup of your files (like documents, images, music, and videos) so that they won't be affected in case there’s a ransomware attack. Bitdefender also detects when ransomware is trying to encrypt your files, blocking all malicious processes before it can cause serious issues.


Even though it's not always possible to remove the ransomware encryption, the encrypted files can always be replaced with prepared backups. That way, you don't have to worry about potentially losing important documents or other sensitive data.


Although the Antispam feature sounds quite self-explanatory, it's a bit more complicated than it would seem. This feature is designed to work with any mailbox, providing active protection for the whole email channel. To achieve that, it uses a Whitelist, a heuristic filter, and learning modules.


For each received email, Bitdefender performs an analysis investigating the message contents, the header, and metadata. It's done to find particular telltale spam characteristics. You can even toggle blocks for emails encoded in Cyrillic or Asian characters.

The learning module works in conjunction with this filter, gathering statistical information about the frequency of genuine emails and spam messages. With proper adaptation, this module can detect spam messages faster than any trained cybersecurity expert.

The last of the triad is the whitelister. It allows you to put in trusted domains, so they won’t be marked and scanned as spam.

I’ve challenged this feature and tried its ability to identify spam emails. This tool successfully managed to identify and flag spam mail, meaning that it successfully protects your data.


Bitdefender Anti-tracker is a solution available to premium users who want to stop excessive tracking carried out by web services. It's no secret that most websites are tracking every click you make via third-party scripts, cookies, and other ad tech marvels.


Anti-tracker is an add-on that you can set up on Mozilla Firefox, Google Chrome, and Microsoft Edge. Once enabled, it will stop malicious scripts from harvesting your data when you're surfing the web. Also, you can manage which tracking categories you would like to allow or disable. For example, you might be OK with website analytics but against ads or social media tracking. You can customize this add-on in a way that works for you, and it quite significantly reduces the load time of all websites.

Bitdefender VPN

One of the key differences compared to many other antivirus service providers is that Bitdefender offers a VPN as part of the app. This is really generous because some antiviruses charge an additional fee for their VPNs or add them as additional products when buying the most expensive packages.


However, you can also buy the VPN separately – this would cost you $3.33/month for a yearly plan.

While this is a good VPN option when it comes to antivirus software providers, it cannot compete with premium options like NordVPN, Surfshark, or others. Bitdefender offers only one tunneling protocol – Catapult Hydra, and while it is fast, there isn't much information on how secure it is. However, this VPN provides you with AES 256-bit encryption, so your data is successfully hidden.

Yet, if you’re really serious about your security and anonymity, this might not be the VPN for you, since it doesn’t have an independently verified no-logs policy.

On the other hand, there’s plenty to like about Bitdefender Premium VPN:

  • Has 4000+ servers in more than 53 countries.
  • Unblocks Netflix US and a few other streaming services.
  • Has a kill switch, which will disable your internet traffic if your connection to the VPN servers is disrupted.
  • Includes an Auto-connect feature when you switch to a public Wi-Fi network or when you visit specific websites.
  • Offers split tunneling, which allows you to exclude the websites of your choice from the VPN traffic.

However, if you purchase the cheaper plans of Bitdefender antivirus, you’ll get only 200 MB of data per day. But, if you buy the VPN separately, you’ll get unlimited data.

Password manager

Rather than developing a standalone project, Bitdefender integrates its password manager into the main dashboard. And if you're using Bitdefender on multiple devices, you'll appreciate the ability to sync the password across all of them.


Some of the features included in the password manager are:

  • Password wallet – here you can store your passwords and choose which browser you can use this feature on.
  • Password generator – helps you generate strong passwords to up your security.
  • Auto-save and auto-fill – pretty self-explanatory, these features allow you to automatically save new passwords into your password wallet. And you can also fill them in automatically.

This is a pretty easy-to-use password manager with a few features. It’s great for new users and is pretty secure. However, premium password managers offer higher security by including two-factor authentication and are more feature-rich, like NordPass or Keeper.

So, while this is a great basic password manager option and a superb addition to an antivirus suite, there are better password managers on the market.

Digital Identity Protection

Bitdefender can monitor the web 24/7 and notify you if your critical information has leaked online. Specifically, the service will check breached databases on the dark web to ensure your social security number, various login credentials, and payment details aren’t exposed to threat actors.

It’s important to note that you must purchase this feature separately for at least $7.99/month to gain its benefits. Moreover, it comes in three tiers, with each subsequent plan offering more perks than the previous.

  • Digital Identity Protection ($7.99/month or $39.99/year). The first subscription option grants 24/7 dark web monitoring services.
  • Identity Theft Protection ($8.99/month or $79.99/year). Upgrading adds 1 bureau credit status monitoring, ID theft restoration services, and up to $1 million in identity theft insurance.
  • Identity Theft Protection Premium ($11.99/month or $109.99). The ultimate plan includes bank and credit card activity alerts, bureau credit status monitoring for 3, and increased insurance budgets.

Extra security features

Aside from all the necessary security features, Bitdefender also offers lots of extra features that you might find incredibly useful, such as microphone and webcam protection, web protection, SafePay, VPN, and more. Here’s a brief overview of each:

  • Microphone and webcam protection. This feature protects your camera and microphone from unauthorized access. I tested this feature and found that it does notify you each time any app or website accesses your camera or microphone. However, you won’t be notified when an attempt to access is made, only when something has successfully accessed your webcam or microphone.
  • Web protection. This feature includes an anti-phishing tool that catches all of the online threats against your data and device. It protects you from visiting malicious sites that may target your data, prevents visiting sites with downloadable malware, checks for fraudulent websites that try to unlawfully exploit user’s finances, warns you about dangerous pages on your search results, and checks the validity of SSL/TSL certificates of encrypted websites.
  • System optimization. It’s a system tune-up tool to free up space on your device and get rid of older and no longer necessary files, including old installation files, registries, junk files, outdated drives, empty files, etc.
  • SafePay. This is a secure web browser aiming to protect you when making online purchases. It creates a sandbox that acts separately from your other browsers, making it unaffected by the malware that could be present on your regular browser. Also, this feature checks if your connection with the Wi-Fi network is secure and uses a virtual keyboard, so your keystrokes can’t be registered by malware.
  • Profiles. These are settings presets that adapt to the conditions you're in and allow you to optimize your computer performance. According to what you're doing, there are several modes: work profile, movie profile, game profile, public Wi-Fi profile, and battery mode profile. You can choose manual or automatic switching between profiles.
  • Parental controls. This feature protects your device from unwanted content. Parental controls feature includes website blocking, app use restrictions, device usage schedules, screen time limit, access to phone contacts, device's location.

How to install Bitdefender

  1. Go to the Bitdefender website and choose your antivirus plan
  2. Activate your license, download the app, and install it
  3. Click the “Start Using Bitdefender” button, so the main menu pops up
  4. Enable the wanted security features, like the ransomware remediation feature for stronger device security
  5. Run your first device scan

Bitdefender ease of use and setup

After picking the plan for you, Bitdefender's setup might take some time, which can be irritating, since the installation files are 400 MB. However, it did surprise me after all, as the installation and setting up took no longer than 10 minutes. Obviously, it all depends on the device you use.


Once I set it up, the app was pretty easy to navigate. I found the interface very well laid out and I especially liked the fact you can customize the dashboard by adding “quick actions”. The default suite groups feature in 3 categories: Protection, Privacy, and Utilities. There's also a Dashboard that provides quick actions and displays your status, Settings, and Notifications tab.

  • The Protection tab is almost exclusively dedicated to the things associated with most antivirus tools. There are real-time protection settings, firewall monitoring, ransomware countermeasures, and more.
  • Privacy deals with methods to stay anonymous and secure when surfing online, like the SafePay browser, VPN, password manager, and parental controls.
  • Utilities are for optimization tools, profile management, and file shredder.

Overall, I found the Bitdefender app very intuitive and easy to use. Clearly, its interface will be easy to navigate for both beginners and more advanced, business users.

Impact on PC performance

When it comes to Bitdefender’s impact on the device, the term "lightweight" doesn't simply imply minimal consumption of system resources. During my tests, I monitored the extent to which the software used my system resources. It's important to note that higher CPU loads can hinder the performance of other tasks.

bitdefender impact on pc performance

During a full scan, Bitdefender used 50% of the device's CPU, which is very light on the resources when compared to other antivirus providers. Additionally, Bitdefender’s full scan caught all malware samples on my test device. Avira, for example, used up to 92% of CPU and only caught 70% of malware samples.

Bitdefender mobile apps

Bitdefender has dedicated apps for both Android and iOS (they’re included in the Total Security package). I tested both of them to see if the apps are equally good and offer good protection for your device no matter the OS it works with.

The differences between the Android and iOS mobile security apps are pretty big. While both apps were easy to download and set up, the experience of using them was different. The Android version is clearly the superior one, while the iOS apps only cover the basics and feel like an afterthought.

Bitdefender on Android

The Bitdefender Android app is really secure, easy to use, and even considered to be one of the best antivirus for Androids. It mirrors the desktop version, is easy to use, attractive to the eye, and includes all the needed security features for your mobile device.

Bitdefender scan on Android

The features included in the Android version are:

  • A malware scanner constantly scans and protects your device from cyber threats.
  • Web protection toggle can be enabled on your browser. It protects you from visiting malicious websites.
  • Scam alert protects you from fraudulent links in your messages.
  • VPN feature, which caps at 200 MB of data per day, comes with the ad and tracker blocker.
  • The Autopilot feature advises you on how to be safer when using your phone. It also scans all your new apps for potential threats.
  • App lock is useful for limiting access to certain apps, in case you lend your device to other people.
  • The anti-theft feature helps you find a lost or stolen device, by showing the last known location. Additionally, you can send a message to the missing device or make it ring loudly. Also, there’s an option to remotely wipe the system.
  • Identity protection informs you if your email was included in the recent data breaches. And it checks for leaks on the Dark Web too and helps with strengthening your passwords.

Bitdefender on iOS

The iOS version of Bitdefender Mobile Security is fairly lackluster compared to the Android version, lacking features like a malware scanner, scam alert, or the Autopilot feature. However, the app is very safe, easy to use, and is a great addition to your iOS security. It’s also one of the best antivirus apps for iPhone after Norton Antivirus and TotalAV.

The iOS app comes with:

  • Web protection feature secures your browsing online, so you don’t visit malicious sites.
  • Privacy monitoring is useful for keeping track of any of your accounts that may have been involved in data breaches.
  • VPN that caps at 200 MB for a day, which, differently than the Android version, doesn’t come with an ad and tracker blocker.

So overall, you're getting privacy monitoring, a VPN that should be enough for a couple of pages, and browser protection in a single app. This is disappointing since most of the antivirus software for iOS don't provide many additional features, due to Apple’s devices being less prone to malware threats. And Bitdefender antivirus still has room to improve when it comes to iOS security.

Customer support

The best thing about Bitdefender’s customer support is that it’s not a premium subscription feature. You can get help whether you're a free or a paying user. And there are many different ways to access any support you might need.

Live chat support✅Yes
24-hour phone support✅Yes (28 numbers across 18 countries, including a worldwide number)
Email support✅Yes
Knowledge database✅Yes
Community support✅Yes

Their live chat support works really quickly – you can get in contact with a reliable support agent in a couple of moments. And they’ll answer all your questions quickly and solve your problems efficiently. This is a massive improvement over contenders like Norton when we had to wait as long as 20 minutes for a response.

To make their work easier, Bitdefender also has a vast collection of FAQs, guides, and other information on the support website. So, while you're waiting in line, it might not hurt to check there. You might resolve your issue before your turn comes.

If you prefer other methods, you can call them via phone and contact them via email. Whichever way is the most convenient for you, you have options there. Customer support alone makes this service an easy recommendation.

Bitdefender video review

In case reading the whole Bitdefender review seems like too much work (and we don't blame you for that!), you can watch our video review instead. In less than 10 minutes, you'll hear all the information you need to know before getting this security tool.

Is Bitdefender worth it?

Bitdefender is one of the best antivirus software on the market. With excellent malware detection and removal rates, it will efficiently protect your device from zero-day threats. The combination of real-time protection, web protection, and multiple personal security tools make Bitdefender the perfect all-rounder. Its apps are easy to navigate, it offers great features, including a VPN and password manager, and the prices are budget-friendly.

However, I have also encountered some downsides. The iOS app lacks some features, the VPN usage is capped, and the web protection feature could be improved.

All in all, Bitdefender antivirus app has excellent protection and great features to offer, but there’s still room for improvement. Its free version is great for malware detection and removal, but if you want more features – go with a paid plan.

How we tested Bitdefender

We conducted in-house tests and consulted third-party antivirus lab results to find out how good Bitdefender is.

The first evaluation involved putting the service’s real-time protection against 10 zero-day malware samples. To do that, we download the files to a device with Bitdefender installed to see if the software reacts appropriately.

After that, we repeat the test with real-time protection disabled to check whether quick and full scans can detect the malware samples. During this time, we monitor metrics like CPU, memory, and disk load to see how Bitdefender impacts overall device performance.

Unsurprisingly, we conduct these tests on all possible device and operating system combinations to see whether protection results are consistent. This approach also allows us to check relevant Bitdefender aspects, such as feature availability and ease of use.
