Got Malware as "JS:Pdfka-gen" with ipa file

Hi Apple.

Currently we're facing an issue when exporting the file as an ipa, by mean our previous ipa file version giving Malware as "JS:Pdfka-gen" inside, we do the app scanning with https://www.virustotal.com/, it saying that there is a "JS:Pdfka-gen" inside the ipa file, is there any solution or hint how we can prevent the issue, because also testflight is accepting the ipa build that containing that Malware.
