== Overview ==
'''BitDefender Online Scanner''' was a free web-based antivirus scanning service provided by [[Bitdefender]]. It allowed users to scan their computers for viruses, malware, and other security threats without installing full antivirus software. The scanner used the same detection engine as Bitdefender's desktop security products, providing an effective tool for on-demand virus detection.

* Detects and removes viruses, trojans, spyware, and other threats.

== Compatibility ==
BitDefender Online Scanner was compatible with:
