PDF detected as a virus

[cryo75]

I'm using this class to check uploaded files. One file is a normal PDF based on images taken using a mobile. I can locally save the file and open it without issues. The class is used in a website where I can upload files.

The problem is that some PDFs are flagged as a virus. Could it be related to Windows Defender itself?

@cryo75 Can you confirm if any file you scan is flagged as virus, or is it just few/specific ones?

I confirmed I had the same issue trying with different files pdf.
