Bitdefender not detecting anything, but TotalVirus does. What the hell?

You need to understand the different categories of Bitdefender engines available on VirusTotal.

• The Bitdefender Falx engine is for only Android malware.
• The Bitdefender Theta engine is completely based on machine learning/artificial intelligence. It is not available in any of the Bitdefender products, whether for home users or business/enterprise users. It has a high chance of false positives. However, it provides malware researchers an option to check if the detected file is indeed malicious. If it is, a detection will be created against it, and the detection will be seen under the standalone Bitdefender engine.
• The standalone Bitdefender engine on VirusTotal is the same as what is available in Bitdefender products for home users and business/enterprise users.

Since the Bitdefender standalone engine does not show any detection in VirusTotal, your Bitdefender product will also not show it.

If you believe that a website or file is not detected by Bitdefender as malicious or phishing, kindly report it to our malware research team using the forum provided at the link below:

If the website or file is indeed malicious or phishing, detection will be added within a maximum of 72 hours. However, if no detection is available even after 72 hours, please consider the website or file as safe, as determined by our malware researchers, and no detection will be created for them.
