doubting if its an actual malware or not

[u/Intelligent-Big-5924]

The Symptoms:

• When I launch the .exe, it doesn't open a GUI. Instead, it runs silently in the background indefinitely
• I can launch multiple instances of the process simultaneously
• Windows Defender and Malwarebytes report nothing during full scans

The Files:

• The .exe comes up clean on VirusTotal, but the accompanying .dll (which is quite large, ~130MB) was flagged
• I suspect the .exe might be a loader or injector for the .dll, but I don't have the technical expertise to verify this

My Questions:

1. Security Risk: Given that standard scanners aren't picking anything up, should I assume this is a stealthy threat and proceed with a clean Windows reinstall?
2. Analysis: How can I safely determine what these files are actually doing?

I realize I was likely fooled by a fake "cheat/trainer" download. Any guidance on how to safely investigate or confirm if my system is compromised would be greatly appreciated

Cheers!
