Best way to hide a SPYWARE ?

Greetings,

I aim to deploy A SPYWARE on a Windows OS device through email or a Mega link. Acquiring the spyware, sourced from a GitHub project is easy. However, the payload consistently triggers detection, even from the basic windows security (no anti-virus)

Here are potential strategies I’m considering :

– Employ a software packer.
– Implement encryption.
– Modify the signature version.
– Utilize a dropper.
– Convert the file format from .exe to .lnk.

What do you think of this different method ? Which one did you try ? Which one is easy ? Which one work ?

Thanks in advance
