I found this hidden file in my friend's flash drive, which might be a virus that cannot be detected by Bitdefender antivirus.
/applications/core/interface/file/attachment.php?id=19792" data-fileExt='zip' data-fileid='19792'>virus.rar.zip
Thank you for the sample.
The guys from the LAB will take a look !
Detection added as "Trojan.Downloader.VBS.Agent.CO".
Best regards.
