Verdict Safe

Analyzed , 12 hours ago

Is gup.exe safe? Yes, no threats found.

This is the genuine signed Notepad++ updater, flagged by none of the 71 antivirus engines that checked it and widely distributed, so it is safe on its own.

Strong evidence · A verified publisher signature, and no engine flags it.

Run it as usual if it came from the official source

Safe when it comes from the official Notepad++ package. Do not run it if it arrived alongside unexpected extra DLL files or inside an unrelated download.

Good practice2 tips

We found nothing harmful in this file.

  1. Run it only if it came from the developer's own website or an official app store.

  2. Keep your antivirus and Windows updates switched on.

No scanner can promise a file is 100% safe.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

None of the 71 antivirus engines that checked it flag it, and nearly 3,000 sources have submitted it. A split sandbox result and generic community rules do not outweigh that. The only real risk is a malicious DLL planted beside it.

Full reasoning

The file carries a valid signature from Notepad++, a trusted publisher, and none of the 71 antivirus engines that checked it flags it, including 18 major antivirus engines that all report clean. It has been submitted by about 2,900 sources since March 2025. The community rules that matched are generic anti-debug, certificate and compiler detectors. One sandbox run returned a malicious label while another returned clean, with no named injection target or other corroboration, which is typical of installer and updater behaviour. Community comments describe a bundle that pairs this genuine updater with a fake DLL; that threat lives in the extra DLL, not in these bytes.

Detailed assessment

What We Detected

No antivirus engine flags this file. It is signed by Notepad++ with a valid signature and matches a trusted publisher. It is also widely seen and consistent with a previous safe verdict for the same signer.

Threat Behavior

The sandbox summary was split, with no named injection target, no dropped files and no malicious contacted hosts. The network contacts are the analysis VM's own background traffic. Community comments warn that attackers sometimes ship this genuine updater next to a fake libcurl.dll that loads a payload. That scenario involves a separate malicious DLL, not the updater itself.

What To Do Now

Use it only from the official Notepad++ distribution. If it arrived in an unrelated download or alongside unexpected DLL files, do not run it.

Where this verdict could be wrong3 caveats
  • One sandbox run returned a malicious label while another returned clean; the malicious run named no injection target and no corroborating artefact.
  • A community comment describes a malware bundle that abuses the genuine signed Notepad++ updater by loading a fake libcurl.dll placed beside it; the updater itself is legitimate, but it can be misused in such sideloading bundles, so the file's surroundings matter.
  • Another community note mentions the hash being associated with a dropper listing, but this is unverified and no public-database listing exists for this exact hash.

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

Points in its favour
  • Valid signature from the trusted publisher Notepad++
  • None of the 71 antivirus engines that checked it flag the file
  • Submitted by about 2,900 sources since March 2025
  • A previous verdict for the same signer was also safe
Points against
  • Genuine signed updaters can be abused through a malicious DLL placed beside them
  • One sandbox run returned a malicious label that nothing corroborated

Questions & answers

Short answers to the 7 questions people ask most about this file.

Is gup.exe safe?
We found nothing harmful in gup.exe. None of the 71 antivirus engines that checked it flag it. It has a valid digital signature from Notepad++. Run it only if it came from the developer's own website or an official app store.
What is gup.exe?
gup.exe is a Windows program, about 804.7 kB. Its version information says it is “WinGup for Notepad++”. The digital signature from Notepad++ checks out. VirusTotal first saw it on Mar 8, 2025.
How many antivirus engines detected gup.exe?
None of the 71 antivirus engines that checked it flag gup.exe. 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.
Is gup.exe digitally signed?
Yes. gup.exe has a valid digital signature from Notepad++, which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
What is the SHA-256 hash of gup.exe?
The SHA-256 fingerprint of gup.exe is eaac64c113ebaba1fae924ad1b6239a44c8806bf2b85d8dc11a27ad65a981cc1, and its MD5 is bca6478b230b6920fe79b97a3066e835. 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 run gup.exe?
We found nothing harmful in gup.exe, and its digital signature checks out. 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 gup.exe?
This report reflects the scan on Nov 10, 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.

Other files people checked with the same signer, and recent reports with the same rating. A matching signer does not make two files the same: only the SHA-256 fingerprint identifies a file.

All file reports
This report and its SHA-256 fingerprint are public, so the next person who checks the same file gets an instant answer; documents and images are listed by type instead of their file name. A file we had not seen before is uploaded to VirusTotal, whose security partners and subscribers can download it; MalwareTips deletes its own copy after the scan. If you ran this file and are worried, scan your device with up-to-date security software.
