Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.

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.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
High concern: Loaded code directly into memory instead of from a normal file.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Scans through your files and folders.
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.

Detection sources at a glance
Category: generic-trojan
Available reference checks returned no match, but at least one source was unavailable. This is not a clean result.
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.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.

Complete recovery guidance and answers for the next decision.
What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't use it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.
- Recovery step 03
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
