Hi Anastasiia,

The exit code `-1073740791` means the program crashed (on Windows). This type of issue may be a security vulnerability, depending on what is going on.

If you could share the PDF file with my team privately, I would like to investigate. You can email it to me directly in an encrypted / password protected zip archive, or send it to Cisco PSIRT using these instructions, and they will relay it to me for investigation: https://github.com/Cisco-Talos/clamav/security/policy#vulnerability-reporting-best-practices

Subject: [clamav-users] Meaning of the exit code -1073740791

Dear Sir or Madam,

I am using ClamAV for work in my company and am contacting you to inquire about an exit code, which the software returns at my attempt to scan an ordinary, virus-free PDF file:

-1073740791.

Could you, please, tell me, what the exit code stands for, as I have not found any information on it in the documentation on your website.

Thank you in advance.

Kind regards,
