Unsigned installer with zero engine detections but import-table fingerprint matches to previously suspicious samples.

Read the whole reasonShow less

Why Suspicious? unsigned installer.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't install it until you know where it came from

Treat as borderline; do not execute on production systems until a signed version or additional reputation data is available.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't install it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already installed it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

No antivirus engine flagged the file, yet the import-table fingerprint matches four prior suspicious and one malicious installer. The unsigned status and single sandbox run showing leave the risk level unresolved.

Where this verdict could be wrong1 caveat
  • similarHashes shows 4/5 prior import-table fingerprint matches flagged suspicious despite zero engine detections — possible installer-framework false-positive pattern.

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

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Moderate concern: Checked whether it was running on a test computer.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Looked through folders on the test computer (most installers do this).

  • Note: Loaded extra code modules while running.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Questions & answers

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

Is OverlayCat_1.1.0_windows_x64-setup.exe safe, or is it malware?
OverlayCat_1.1.0_windows_x64-setup.exe is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. No antivirus engine flags it; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run. Don't install it unless you're sure where it came from. If you need the software, download a fresh installer from the developer's own website.
What is OverlayCat_1.1.0_windows_x64-setup.exe?
OverlayCat_1.1.0_windows_x64-setup.exe is a software installer, about 32.4 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Jul 23, 2026.
How many antivirus engines detected OverlayCat_1.1.0_windows_x64-setup.exe?
None of the 69 antivirus engines that checked it flag OverlayCat_1.1.0_windows_x64-setup.exe. A clean antivirus result is not proof of safety; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run.
What should I do if I already installed OverlayCat_1.1.0_windows_x64-setup.exe?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of OverlayCat_1.1.0_windows_x64-setup.exe?
The SHA-256 fingerprint of OverlayCat_1.1.0_windows_x64-setup.exe is 75833b331c6b997e6e669490f6c47730dc0e56521c05b53e4242eaee52db0404, and its MD5 is be196f6e52f2d34cfe1c91d01d1b2db5. 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 OverlayCat_1.1.0_windows_x64-setup.exe?
This report reflects the scan on Sep 7, 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.
