[BUG] Crash when trying to send a big file to VirusTotal

Open ElektroStudios opened this issue 6 months ago • 3 comments

The property sheet dialog window (including explorer.exe process) silently crashes when trying to send to VirusTotal a file larger than the maximum allowed file size).

I've tried it with movie (.mkv) files.

PS: I've read somewhere (through Google Search results) that the allowed file size limit is 650MB, but I think that would be for the web browser interface, since the API docs says the common limit is 32MB: https://docs.virustotal.com/v2.0/reference/file-scan

Interesting... The VirusTotal feature can only send hashes and not upload files, so size shouldn't matter at all.

Thank you for the fast reply. and sorry because I mistakenly assumed what the program was trying to do and why caused a crash. It seemed very strange to me that generating a hash, even for a large file, would cause it to crash.

What you said has helped me conclude what the real problem is:

When loading a file of certain size, the user can press the "Cancel" button when generating the hash, but the blue VT button will be enabled. So pressing the VT button to send a not yet generated hash will crash the program (and explorer.exe process will restart):

Another thing of much lesser importance, which I don't think it's worth creating a new thread just to expose this, but as you can see in the GIF images, the red colored error/hash cancellation message(s) appear in my operating system language (Spanish from Spain, "es-ES") instead of English, despite having specified LCID 1033 for "en-US" in the corresponding registry key.

Maybe you could find the way to improve the consistency of this in future versions.

Best regards.
