What are the Key Features of Bitdefender?

Malware Protection

Results of Real-World Protection Report conducted February-May 2021 (AV-Comparatives)

Bitdefender antivirus provides multi-layered protection and saves all the devices from existing and new malware threats. The best part of Bitdefender’s protection is the cloud feature, as most of the work is done there, which essentially means that it doesn’t affect the computer’s performance. Bitdefender is hands-down the best antivirus product on the market when it comes to protection against viruses and other malicious software. It’s been proven by various respected testing labs. For example, AV-Comparatives’s Real-Life Protection Report states that Bitdefender was the best provider overall. Bitdefender was able to identify 735 out of 736 threats with no false positives, which is outstanding. To read more about the way AV-Comparatives test software and the details of this particular report – check out this website.

AV-TEST Protection Analysis 2021 To detect and eliminate threats that were able to penetrate your device, Bitdefender offers three main scanning options: Quick Scan, System Scan and Custom Scan.

Quick Scan

This type of scan fairly quickly goes through your computer’s most vulnerable areas like downloads, temporary files and mail downloads to make sure that you stay safe in between system scans.

System Scan

It scans your entire system and removes all kinds of malware, viruses, and potential threats from your computer. However, the deep scan will take a lot of time, and the estimated scanning duration is around an hour. It’s still faster than most of the competitors.

Custom Scan

Here, you will get an opportunity to scan selected files that you think might have got infected.

Time Machine Protection

This feature protects the files from encryption by ransomware. When ransomware attacks a device, it encrypts files like photos, videos, documents, etc., and makes them unusable. To get them back, you’d need to pay some amount to those who planted that software. This feature creates an additional layer of security for system backups and blocks access to any external source that tries to tamper with your backups.

Parental Control

Parental Control helps parents track children’s online activity and keeps them safe online This feature is available in most OS such as Windows, Mac, and Android, but there’re some differences among those apps.

How Does Bitdefender Maintain my Privacy?

Bitdefender Antivirus software respects customers’ privacy and protects the personal information of customers through multiple tools explained below.

Adware blocker

Junk ads popping up on screen create disturbance and affect your work performance, and I guess we can all agree they are simply annoying. Sometimes, they also have adware infections aimed to infect your device. Bitdefender has an Adware blocker to stop these unwanted ads and let you enjoy the device’s full potential.

Cross-Platform Malware detection

It is designed to protect one type of device from the malicious content of another type of device. So you can safely transfer files in between various devices.

Traffic Light (Browser Extension)

It uses artificial intelligence to filter out unnecessary and inappropriate links even before you are browsing. So you never open harmful websites.  

Bitdefender VPN

VPN is designed to allow you to connect to the Internet through a secure tunnel. It encrypts all the internet traffic to make sure no one can read your data even if they take a hold of it. Using Bitdefender VPN, you can digitally roam across 30 countries as you get a pass of 30 servers. But this feature is enclosed in the Bitdefender’s VPN premium plan, not in the basic one. The free version offers up to 200 MB/day, which is limited but pretty standard. The paid version offers unlimited data for up to 10 devices. Unfortunately, it doesn’t provide a kill switch feature that means that you still can access the internet even if the connection with a VPN server was interrupted.


Bitdefender offers robust features to speed up your computer’s performance so that you can enjoy safe browsing without any interruptions. According to the AV-Comparatives Performance report from April 2021, Bitdefender provides Advanced+ Performance. It means that those features really work! Let’s take a closer look at what Bitdefender has to offer.


Its role is to act as a security advisor and give insights into the device’s security posture. It also recommends security options according to the needs and usage patterns of the device, so that you don’t have to think about it too much.

Bitdefender Photon

It’s a unique technology that adapts to your system’s hardware and software configuration to save computing resources and improve speed and performance.

Global Protective Network

Because most of the scanning takes place in the cloud, it frees up your computer resources to do whatever you want.

Game, Movie and Work Profiles

Bitdefender automatically assesses what type of work your device is performing and pauses unimportant background apps and halts pop-ups respectively.


It blocks the trackers, which collect the browsing data of each website you visit. It protects your data and enhances the performance of the device. This feature is available to premium users and supports multiple browsers such as Google Chrome, Firefox, etc. With the help of this feature, you can manage the tracking feature, which means you have control to select which websites can track you.   Using parental control, you can choose the websites you want to screen for your kids and fix the screen time. This will help you monitor the kids’ web activities and how much time they spend on certain websites.

What Features Does It Offer in Terms of Phishing Protection?

Phishing is a scam where scammers send fraudulent messages to victims to reveal important information to the attacker or inject malicious software on the victim’s device. Even though phishing was one of the most popular attacks in 2020, most antivirus vendors don’t possess a great set of features to fight those threats. Phishing attacks are getting sneakier and often look just like legitimate emails. According to AV-Comparatives Anti-Phishing Certification 2021, Bitdefender was able to block 87% of phishing links with 0 false positives. It’s not the greatest result, but it still has what it takes to make your online activity safer.

Can Bitdefender Prevent Ransomware Attacks?

Ransomware is a virus software designed to block access to data on your device until some money is paid to the attacker. Bitdefender is designed to provide multi-layered protection against even the latest ransomware. That way, your data, photos, documents, audio, videos will be safe from such attacks. It works with the Advanced Threat Defense module to protect your most important files from encryption by ransomware.

How Good is Bitdefender at Malware Removal?

Bitdefender is a top-performer when it comes to removing malware. Bitdefender’s Shield scans the files and email attachments for the malware, and if found, it immediately removes it from your PC. It protects you in many ways against unwanted applications, network share, boot sectors, keyloggers, and others. The advanced technology of Bitdefender’s Real-Time Protection will instantly block the malware file and thus prevent you from accessing it. But in Bitdefender’s Shield, the Save button will turn gray, which likely represents that you should avoid such a file.

Using this browser, you can safely browse the websites and also can access an inbuilt VPN. If you are using a virtual keyboard, it will prevent keystroke tracking and thus secure your credentials. But in this browser, you can’t take a screenshot because the browser has an inbuilt screenshot blocker. Safe browsers have their downfalls, but we strongly recommend using them for online payments and visiting websites that contain sensitive data.

Password Manager

Are you tired of recovering your passwords from all those websites? We feel you. But storing your passwords in a browser isn’t always a good idea. That’s why Bitdefender offers a password manager.
