Is OperaSetup (4).exe safe? Not fully confirmed.

Unsigned installer submitted when we scanned it on Aug 1, 2026 with zero engine detections but no prior reputation.

Read the whole reasonShow less

Why not Safe? It has no verified publisher signature, only one source had seen it when we scanned it and no sandbox test run results are available.

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

Keep normal caution and get it from the official source

Treat the file as unverified; obtain a signed copy from the vendor before running.

Good practice2 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.

The reasoning behind this verdict

Analyst conclusion

The file is an unsigned Opera installer. No engines flagged it, yet the complete lack of history and unsigned status leave its safety undetermined.

Where this verdict could be wrong3 caveats
  • Unsigned installer with zero prior reputation could still be malicious despite clean engine results.
  • similarHashes import-table fingerprint matches are framework collisions, not strong signer evidence.
  • The missing contacted-host reputation result means no complete host-reputation result is available.

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

How many antivirus engines detected OperaSetup (4).exe?

This report reflects the scan on Aug 1, 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 To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
