Bitdefender Antivirus Free Edition Review – Fierce & Lightweight Protection for Windows 10.

Best Free Antivirus Products for Windows PC in 2019 – Bitdefender Antivirus Free Edition.


Bitdefender Antivirus Free Edition protects its users by using their famous Intelligent Antivirus engine that blocks all kinds of malware. Along with the power of signatures, you get Bitdefender’s behaviour-blocker called Active Threat Control as well. The free version also includes Bitdefender’s Advanced Threat Defense technology that uses advanced heuristic methods to protect against ransomware and other advanced threats.

The web-filtering component called Safe Browsing along with Anti-Phishing & Anti-Fraud modules provides protection from harmful websites and web-based threats. You can enhance the web protection by installing the free web browser add-on/extension by Bitdefender called TrafficLight. Bitdefender TrafficLight has following features – Advanced malware filter, Protection against phishing attacks, Trackers identifier, and Link scanner. Bitdefender Photon is not available in the free version of their antivirus.

Overall, it’s a great product but if you want to play with some settings then look elsewhere because you won’t find any here. Only two scan modes are available for free users. One is System Scan, which is the full computer scan. The other scan mode is kind of a custom scan. You can drag and drop the selected files or folders in the program window to start scanning. A minimalistic design and a very competent program full of award-winning technologies yet very lightweight.

The program is the most minimalistic in the antivirus market. Most of protection technologies by Bitdefender are present in the free version to protect you but you won’t find any advanced features here. It only has the essential features such as Quarantine, Exclusions, and Full System Scan. If you want a set it and forget it type antivirus then look no further.

The Settings button in the home screen opens the doors to all of the options that this program has for you.

  • Events
  • Quarantine
  • Exclusions
  • Protection
  • Account Info
  • Help and Support

Clicking on the Events button opens the Events window of Bitdefender. It lists all of the events such as last update, last scan, last malware detection, etc.

The Quarantine button opens the Quarantine window, which lists the files that Bitdefender blocked, and hence sent to the Quarantine section. You can apply various actions on the Quarantined files such as Restore, Delete, etc.

Similarly, the Exclusions button opens the Exclusion tab on the Settings window. Here you can specify the files and folders that you want Bitdefender to exclude from its jobs.

The Protection tab will take you the Protection window. This is an important component; as you can see, the Protection can be turned On or Off just by clicking this button. It also displays the information about the Product version and the Antimalware Engine being used in the product.

Lastly, we have the Account info button, which will open the User Account Information window. Here, you can check your account credentials. You can click on the Bitdefender Account button to go to Bitdefender’s User Dashboard login page.

The final item in the menu bar called Help and Support will take you online to Bitdefender’s help guide.
