Suspicious
Unsigned PDF with embedded JavaScript and auto-action tags submitted only twice in the last day.
42d44097a46cad5fdc…fbf5a4a512The verdict, reasoned out.
Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.
Zero malicious detections across 62 engines rules out known malware families. However, the file carries 'js-embedded' and 'autoaction' tags on a PDF that is only hours old and has been seen by just two submitters. Unsigned status and complete absence of similar-hash history leave no benign anchor. These factors together produce a borderline case that warrants caution rather than outright clearance.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

Safety FAQ
Common questions about certificato_di_conoscenza_della_lingua_italiana_ 2.pdf, answered from the scan data above.
- certificato_di_conoscenza_della_lingua_italiana_ 2.pdf is suspicious — treat it as unsafe until you're sure. 0 of 74 antivirus engines flag it, which isn't a strong consensus but is enough to be cautious. Don't opened it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
- certificato_di_conoscenza_della_lingua_italiana_ 2.pdf is a document file (application/pdf), about 7.7 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
- None — all 74 antivirus engines we queried report certificato_di_conoscenza_della_lingua_italiana_ 2.pdf as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove certificato_di_conoscenza_della_lingua_italiana_ 2.pdf: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete the original certificato_di_conoscenza_della_lingua_italiana_ 2.pdf file and empty the Recycle Bin/Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- The SHA-256 hash of certificato_di_conoscenza_della_lingua_italiana_ 2.pdf is 42d44097a46cad5fdc5466598a0aac581b25469e0e735975446338fbf5a4a512, and its MD5 is a8be4b1da25793da4752bcb5f40a0c29. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- This report reflects the scan run on July 11, 2026. Because a file's hash never changes, the identity of certificato_di_conoscenza_della_lingua_italiana_ 2.pdf is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
