Is OperaSetup.exe safe? Not fully confirmed.

None of the 52 antivirus engines that checked it flagged this Opera-named installer and sandbox runs showed nothing hostile, but it is unsigned, and seen only once.

Read the whole reasonShow less

Why not Safe? It has no verified publisher signature and only one source had seen it when we scanned it.

Limited evidence · Nothing points to a problem, but little confirms who made it.

Keep normal caution and get it from the official source

Do not run this copy unless you downloaded it directly from opera.com. Get the installer from the official site and confirm it is signed by Opera before installing.

Good practice3 tips

Low Risk: no threat found, but we could not fully confirm this file.

  1. Get it from the publisher's own website or app store, not from a re-upload or a link someone sent you.

  2. Keep your security software on, and stop if the file does anything you didn't expect.

  3. It is only 4 days old. If you're unsure, scan it again in a few days; antivirus engines often catch up on new files.

The reasoning behind this verdict

Analyst conclusion

None of the 52 antivirus engines that checked it flagged this file, and three sandbox runs recorded no high-risk techniques. However, the installer carries no code signature, which genuine Opera installers normally have, and it was first seen on Oct 22, 2026 from a single submitter. That leaves too little to confirm where it came from.

Where this verdict could be wrong1 caveat
  • No engine flagged the file, the sandbox runs showed no high-risk techniques, and the embedded strings point to Opera's own website, so this may simply be a legitimate Opera installer whose signature was not recorded.

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 5 questions people ask most about this file.

Is OperaSetup.exe safe?
OperaSetup.exe is rated Low Risk: we found no threat, but we could not fully confirm this file. None of the 52 antivirus engines that checked it flag it, but that alone is not enough to call it Safe. Keep normal caution and get it from the official source.
What is OperaSetup.exe?
OperaSetup.exe is a Windows program, about 3.3 MB. Its version information says it is “Opera installer SFX” (Opera installer). Version information is written by whoever built the file, so it is a claim, not proof of who made it. VirusTotal first saw it on Oct 22, 2026.
How many antivirus engines detected OperaSetup.exe?
None of the 52 antivirus engines that checked it flag OperaSetup.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.
What is the SHA-256 hash of OperaSetup.exe?
The SHA-256 fingerprint of OperaSetup.exe is 300e3fb11b88d316399dcaea59bfe9250e8d3d62a4d5dfab24d9b16c5959e85f, and its MD5 is 13a74540b2b46cafa17a0e36c93d8f89. 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.
How up to date is this analysis of OperaSetup.exe?
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.

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.
