Is euphoria.exe safe?
Two tier-1 detections, unsigned packed code, and possible process injection warrant caution, although broad prevalence and a clean sandbox result limit certainty.
Two of 75 engines flagged this executable, including a key-generator label and a generic trojan label. Its unsigned, likely packed code and possible T1055 process injection are concerning, but the file is long-established, most engines did not detect it, and the completed sandbox did not issue a malware finding.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Two of 75 engines flagged this executable, including a key-generator label and a generic trojan label. Its unsigned, likely packed code and possible T1055 process injection are concerning, but the file is long-established, most engines did not detect it, and the completed sandbox did not issue a malware finding.
Symantec and TrendMicro-HouseCall flagged the file, but they did not agree on a specific malware family and the consensus was not strong. One sandbox run mapped activity to T1055 Process Injection, which is an offensive technique, while that same run did not produce a malware finding. The unsigned executable is marked as likely packed, increasing uncertainty about its concealed code. Conversely, it has circulated broadly since 2015 and 15 of 17 tier-1 engines did not flag it. Host-reputation coverage was incomplete because only seven contacts were inspected despite additional observed domains and IP addresses.
What We Detected
Two of 75 antivirus engines flagged the executable. Symantec identified PUA.Keygen, while TrendMicro-HouseCall used the generic TROJ_GEN.R002H05KR22 label; this is not strong agreement on a specific malware family.
Threat Behavior
One completed sandbox run mapped activity to T1055 Process Injection. The file is unsigned and likely packed, but the run did not produce a malware finding or record dropped file hashes. Network-reputation coverage was incomplete because seven contacts were inspected while the runtime record contains additional domains and IP addresses.
What To Do Now
Do not run the executable on a production or personal system unless its origin and purpose can be independently verified. Keep endpoint protection enabled, and obtain the software from an official source with a verifiable signature or checksum.
Where this verdict could be wrong4 caveats
- Fifteen of 17 tier-1 engines did not flag the sample, and the two detections do not establish strong family consensus.
- The completed sandbox recorded a clean verdict and droppedFileHashes is empty, although one run cannot exclude conditional behavior.
- Symantec's PUA.Keygen label indicates potentially unwanted key-generator software rather than a confirmed malware family.
- Community annotations are contaminated by instruction-like text and were excluded from the decision.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 2/75 engines detected the file
- 15/17 tier-1 engines did not flag it
- One completed sandbox issued no malware finding
- No dropped file hashes were recorded
- 3,100 sources submitted it 5,242 times since 2015
- Two independent tier-1 engine detections
- Possible T1055 Process Injection
- Unsigned Win32 executable
- Likely packed code
- Conflicting PUA and generic-trojan labels
- Incomplete contacted-host reputation coverage
Avoid executing this file unless its source and intended key-generator function are fully trusted and independently verified. Keep security protection enabled and prefer a signed copy from an official distribution channel.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Used an input-capture technique that can record credentials or keystrokes.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Moderate concern: Communicates over the network in a non-standard way.
Moderate concern: Checked the environment for virtualisation or analysis tools.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
Evidence"C:\Users\<USER>\AppData\Local\Temp\software.exe"Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.

Section entropy & packers
A known packer signature (UPX / Themida / VMProtect / etc.) matched this file. Packers aren't malicious on their own, but most malware uses them.
Packers compress or encrypt the executable and only unpack it at runtime. Legitimate commercial software uses them too — but if the file is also unsigned and rare, it's a strong malware signal.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
