Features enhance the antivirus capabilities regarding security, privacy, performance, and even protection against threats. Here are the features Windows Defender and Bitdefender have in store for us.
Unlike other antivirus suites, which you have to download and install, Windows Defender is built into Windows 10. In the latest version of this operating system, Windows Security supplants Windows Defender. However, Windows Security integrates Microsoft Defender Antivirus and other security offerings available in Windows 10.
In this review, when we talk about Windows Defender, we will be referring to Windows Security as a whole. Regarding features, Windows defender is different from other antivirus suites. What you see is what you get. That is, Windows Defender is mainly focused on security and protecting you against threats. Here are the notable features you can’t miss;
- Powerful antivirus engine with ransomware protection.

Apart from the above features, Windows Security also offers other functionalities that are not antivirus-related. These functionalities are made available via other Windows services. These functionalities include Fresh start, drive encryption, one drive for ransomware recovery, and customer support.
Unlike Windows Defender, Bitdefender offers third-party products which require installation. These products have full-blown features that Windows Defender cannot match. Bitdefender offers five premium antivirus products for personal and home use. Two of them are strictly for Windows, while the rest are cross-platform.
We will look at Bitdefender products starting with the low-end product, Bitdefender Antivirus Plus for Windows. This is the base product, but it has more features than Windows Defender. The features are grouped into three categories, protection, performance, and privacy.
Protection features offer on-device and browser security. They also provide online protection. These features include;
- Award-winning antivirus engine with multi-layer ransomware protection.
- Real-time data protection.
- Vulnerability assessment.

Now let us look at the features of Bitdefender cross-platform products. They are compatible with Windows, Macs, Android, and iOS devices. The first product on this list is Bitdefender Total Security. This product packs features of the previous products. Bitdefender Total Security offers complete and advanced protection and is among our recommendable products for 2022.
Its feature additions include the following;

- One-Click Optimizer performance utility.
- Antitheft utilities.
Next in line is Bitdefender Family Pack. This is also our recommendable product, and it has all the features of Bitdefender Total Security. It is suitable for large households or people with more than 10 devices. Its unique addition includes;
- It covers a maximum of 15 devices.
Lastly, the third product; Bitdefender Premium Security. This product offers features of the previous product with one distinct addition;

In comparison, Bitdefender’s vast array of features is unmatched. Windows Defender only offers threat protection. It misses out on other security and privacy-enhancing features.
2. Malware Protection
Despite being a free built-in product, Windows Defender gives other premium antivirus suites a run for their money. Its antivirus engine goes toe-to-toe with Bitdefender’s award-winning antivirus engine. Both engines offer advanced and comprehensive protection against offline and online threats such as viruses, malware, ransomware, spyware, and other evolving threats.
Windows Defender also offers protection against file-less threats using its memory-integrity feature. Additionally, it is equipped with exploit and tamper protection abilities. This prevents malicious apps from turning it off. Occasionally, it can check for malicious code in email attachments in outlook.
It relies on real-time and cloud-delivered protection for faster detection and protection. It also utilizes online analysis, malware-signature and compares new threats to its database of known malware. Unlike other free antivirus products, Windows Defender receives regular definition updates.
On the other hand, Bitdefender boasts a couple of technology enhancements for comprehensive protection. Besides the antivirus engine, Bitdefender products rely on network threat prevention and advanced threat defense. Also, they get access to Bitdefender’s cyber threat intelligence.
Cyber threat intelligence is useful for offering protection against suspicious network-level activities, brute force attacks, and botnet propagated attacks. These technologies also enable Bitdefender products to analyze, identify, and block network threats and stop zero-day attacks on their tracks.
To assess the malware protection capabilities of Windows Defender and Bitdefender, we will rely on tests from independent labs such as AV-Test and AV-Comparatives. These labs use samples that emulate real-world scenarios. The AV-Test samples test for protection against malware infections, zero-day malware attacks, and widespread malware detection.

Overall, Windows Defender and Bitdefender offer impeccable protection against a wide range of online threats. However, Windows Defender lacks security and privacy-enhancing features.
3. System Performance
Besides water-tight protection, a good antivirus suite should not impact your system performance. Currently, the latest updates to antivirus suites ensure they don’t compromise on system performance. Let’s see the influence Windows Defender and Bitdefender have on your devices’ computing speeds.
Windows Defender is an in-built antivirus solution. Generally, you should expect it to have a little performance impact. However, that might not be the case at times. When your system is idle, Windows Defender performs background scans.
If you listen carefully, you might notice your fan is louder than usual, or your computer is heating a little bit: the culprit, Windows Defender. At times, it doesn’t have any significant performance impact.
On the other hand, Bitdefender products have been designed not to get in your way. They have a considerable system impact when running active scans. Bitdefender offers various performance profiles that dictate how it influences your computer performance. Depending on what you are doing, Bitdefender will not hogg your system resources.
Additionally, Bitdefender uses cloud technology to perform heavy scans. Hence, it doesn’t have a noticeable effect on your local resources. Bitdefender products also come with Bitdefender Photon. This functionality helps Bitdefender products to adapt to your system resources and hardware configurations. This functionality ensures you get improved performance and speeds.
To analyze the performance impact Windows Defender and Bitdefender products have on your system, we will rely on test results from AV-Test and AV-Comparatives. These independent labs measure the influence antivirus products have on your computer speeds in daily usage.
They test the impact on computer activities such as file operations, installation, the launching of programs, downloads, and browsing.

4. User Interface
Windows defender has one of the most straightforward, user-friendly interfaces. Again, what you see is what you get; no hidden features or navigation hassles. However, some functionalities are deeply integrated into the Windows system.
Its main window has two panels, the left panel hosts shortcuts to what is available in the right panel. The home dashboard hosts all its seven features. They include Virus and threat protection, Account protection, Firewall and network protection, App and browser control, Device security, Device performance and health, and Family options.
Bitdefender closely follows the Windows layout but with a few modifications. All its products feature a streamlined interface, and features are well organized. The main window sports two panels; a left panel for features and a right panel for hosting the feature functionalities. Features on the left panel include the Dashboard, Protection, Privacy, Utilities, Notifications, and Settings.

Although Bitdefender comes at a price, it gives you great value for your money.
By default, Windows Defender is only compatible and available for Windows devices. However, if you wish to have it on other devices, you should look for the endpoint option. Although being an in-built antivirus solution, Windows gives you the option of installing other third-party antivirus security suites.
The moment you activate a third-party antivirus suite, Windows Defender will automatically turn itself off. Unless the third-party allows it to run in the background. Windows Defender will also automatically turn itself back on the moment you uninstall the other antivirus.
In contrast, Bitdefender products are compatible with Windows, Macs, Android, and iOS devices. The Windows system gets all the features and functionalities while the versions for Mac are stripped. This is the same for the mobile platform. Android has it all, while iOS gets the bare minimum. This is because Macs and iOS platforms are closed and limited to third-party interoperability.
Windows Defender has come a long way. Microsoft has continually upgraded it, and now it offers the best-in-class protection. Regarding malware protection, Windows Defender directly competes with other industry-leading antivirus brands. Although it has some flaws and misses some essential features, Windows Defender is a good antivirus solution.
In a faceoff between Windows Defender and Bitdefender, Bitdefender is the unbeaten champion. It offers comprehensive protection coupled with security, privacy, and performance features. It also doesn’t compromise on performance, and its products are cross-platform.
