Key Features Of Bitdefender

User Interface

A good antivirus software begins with a user-friendly interface that features well-organised elements for easy navigation. We see this in Bitdefender’s interface, which displays a default layout of essential tools and operations on the right, along with a menu of additional/secondary functionalities.

On the dashboard, you have the Quick Scan, System Scan, Vulnerability Scan, VPN, and Safeplay icons. You can also customize your dashboard by adding any feature.

Robust antivirus engine 

Bitdefender’s AV Engine performed exceptionally well by scoring perfect scores in several lab tests. Based on the tests I conducted, Bitdefender’s scanner proved it is worth the rating it got by detecting every malware infection loaded on my system. These malware samples numbered approximately 690, including viruses, Trojans, worms, ransomware, spyware, cryptojackers, rootkits, and keyloggers. 

With a single Full system scan, Bitdefender detected and removed every piece of malware on my system in under an hour. I would attribute its lightning speed to its Cloud-based antivirus engine, which uses advanced AI and ML to identify threats. Also, since it is lightweight, it doesn’t slow down system performance. 

Overall, Bitdefender’s AV Engine performed impressively well, as it is fast, doesn’t slow down system performance, and features a powerful AV scanner with a perfect malware detection score.

Antiphishing functionality 

Phishing sites are common cyber threats that threaten internet safety. Bitdefender has a powerful phishing detection feature that compares the sites you visit with an updated list of phishing and other dangerous sites and automatically blocks access to such websites.

In the test conducted, Bitdefender blocked and filtered all phishing and malicious websites I attempted to visit. Overall, Bitdefender’s antiphishing feature is 100% effective at identifying and filtering fake websites. You also receive a notification of the websites it has blocked, allowing you to easily whitelist any false positives.

Bitdefender Shield (Real-time protection)

Bitdefender’s Active Shield offers real-time protection by scanning files and email attachments as you access them. I ran a test on Bitdefender Shield with over 150 infected samples, including text files, executable programs, and compressed files. 

I also ran network attacks from other systems; surprisingly, Bitdefender’s shield prevented these infected files from downloading and protected me from every network attack I had launched from other systems.

Overall, Bitdefender Shield is effective against Network attacks, Boot sectors, unwanted applications, keyloggers, and other threats. Additionally, you can customize this feature to include scripts, applications, and archives.

Bitdefender VPN

Bitdefender’s VPN isn’t as robust as premium VPN providers but does offer a no-log policy, strong encryption, unblocks geo-blocked and restricted websites, fast download speed, kill-switch technology, online safety, and anonymity.

However, the 200MB bandwidth limit prevents you from doing so much more with Bitdefender’s VPN. To bypass the 200MB bandwidth limit, you can subscribe to Bitdefender’s premium antivirus suite with unlimited Bandwidth or subscribe separately to Bitdefender’s VPN plan.

Password Manager

Although you won’t enjoy additional features offered by premium password managers, you’re sure to enjoy basic features, including secure password storage, password generator, auto-save and auto-fill, and multi-device sync.
