I bought spartan gold last night and the scans are FUD but when i try to run my stub or just copy it on my VM it gets deleted instantly

where is the issue i dont understand

The AntiVirus on my VM is windows defender

It gets detected even if the scan results are clean

Maybe detected by Windows Defender Cloud. Crypters which have many customers would detected by cloudtime detection because many sample is analyzed by AV's cloud system.

Threre's no solution you can do on crypter. As I said cloud detection can happened on crypters with many customers. So there's 2 methods you can do.
1. Make your own crypter which is not detected.
2. Buy a private crypter.

I'm not sure but I think WD Cloud detections occurs when you download your exe from web. Archieve .exe on .ziip and downloading this would not detected by WD Cloud. But if you detected when copy & paste payload to VM it might be a static detect. If then, it's crypter developer's fault.

In fact, mass customer crypter can't make FUD one and very hard to make HQ one.

you can contact crypter owner/seller and he will help you out.
