My AVG installation recently reported "the file "lavasoft_overlay_new_setup_progress_en_836de029-df55-483c-b06e-67c270576b5f-v3.exe has been moved to Quarantine since it appears to be infected by Win32:UnwantedSig (PUP)" right after I installed PDFCreator.

PDFCreator
is a completely open source piece of software, therefore the addition of a malware and the permanence of it in the code (being this latter virtually viewable by anyone willing to check the safety and authenticity of it) seem counterintuitive.

Hence I would need help in understanding whether it may be a matter of false positive or not, so that I can decide whether to delete it or safely remove it from quarantine.

What website should I temporarily add to the Exceptions?
You mean GitHub - pdfforge/PDFCreator: PDFCreator - The free PDF Converter ?

Thank you
