Verdict Suspicious
Is ep_ setup. exe safe? Treat it as suspicious.
Unsigned installer for a Windows shell-modification tool, flagged by 4 of the 69 antivirus engines that checked it, mainly as riskware, that restarts Explorer and places a DLL in…

Why Suspicious? 4 antivirus engines flag it; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
If it came from a link, an attachment or a stranger, delete it.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't install it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
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
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.
Not sure what to do?

Why we think so
3 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
GData labels it riskware for the ExplorerPatcher product, and the other three use generic labels. In the sandbox it closed Explorer, set up a background service and copied a DLL into the Windows folder. That fits a taskbar customisation tool, but the file carries no signature.
Detections are few: GData is the only major antivirus engine, and it labels the file as a riskware product rather than a malware family. The remaining hits come from machine-learning engines with generic labels. The sandbox shows installer activity: it ended Explorer, stopped and restarted its own service, registered a weather component and wrote files into a Program Files folder, plus a dxgi.dll into the Windows directory. No injection into other processes and no network contacts were recorded. The file has 136 distinct submitters since it was first seen on May 19, 2026, and no malware-database or rule hits. Because it is unsigned and deeply modifies the Windows shell, we treat it with caution rather than as clearly clean.
What We Detected
4 of the 69 antivirus engines that checked it flagged the file. GData labels it riskware for the ExplorerPatcher product, and DeepInstinct, APEX and Trapmine use generic machine-learning labels. Sixteen other major antivirus engines reported nothing. The file is unsigned.
Threat Behavior
In the combined sandbox summary, the installer ended Explorer and managed its own background service. It also registered a component DLL and wrote program files under Program Files, plus a dxgi.dll in the Windows folder, which is a shell-hooking technique such tools use. No injection into other processes, no persistence beyond its service and no network contacts were recorded. No complete host-reputation result is available.
What To Do Now
Only run it if you intentionally want this Explorer customisation tool and obtained it from the project's official release page. Expect some security products to flag it, and keep your antivirus enabled.
Where this verdict could be wrong1 caveat
- Only one major antivirus engine flagged the file, and its label is a riskware classification of the product itself. The installer behaviour fits a legitimate taskbar and Start-menu customisation tool.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 136 distinct sources have submitted the file.
- No malware family is named, and there are no malware-database or rule hits.
- Sandbox activity matches a shell customisation installer, with no injection into other processes.
- The installer carries no digital signature.
- One major antivirus engine labels it riskware, and three other engines flag it generically.
- It closes Explorer and places a DLL in the Windows system folder to alter the shell.

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.
Moderate concern: Hid files or windows on the test computer.
Note: Read the user name of the test computer.
Note: Listed the programs running on the test computer.
Note: Deleted files or logs during the test run (installers often clean up after themselves).
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
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 an event trigger; nothing confirms it.
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.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
