The reasoning behind this verdict

Analyst conclusion

None of the 61 antivirus engines that checked it flagged this PDF document, and it has been circulating since 2022 without detections. Sandbox runs show Acrobat opening it normally, with network traffic only to Adobe hosts. It contains embedded JavaScript and an automatic action, which interactive manuals often use.

Where this verdict could be wrong1 caveat
  • The PDF carries embedded JavaScript and an automatic action; these are common in interactive manuals, but our own static analysis did not examine the bytes, so their content was not reviewed.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is this PDF document safe?
We found nothing harmful in this PDF document. None of the 61 antivirus engines that checked it flag it. Open it only if you trust the person or website it came from.
What is this PDF document?
This PDF document is about 28.4 MB. Its original file name is hidden on this page for privacy, so we identify it by its SHA-256 fingerprint. VirusTotal first saw it on Aug 8, 2022.
How many antivirus engines detected this PDF document?
None of the 61 antivirus engines that checked it flag this PDF document. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of this PDF document?
The SHA-256 fingerprint of this PDF document is 149a47bdb5d141c341aad51397b87961f48d0c9392fb50cc100485569d23a916, and its MD5 is 6b2a90ab5490a9cdac48cc1893bc6e84. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to open this PDF document?
We found nothing harmful in this PDF document. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of this PDF document?
This report reflects the scan on Oct 22, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
