How can I make clean malware?

[Dfint01]

If I use remote access tools for example like : XWorm, VenomRAT ...etc.
How can I turn the trojan into Fully Undetectable Payload (FUD).

Depending on the trojan you may use an obfuscator, this may help.

if you need i have crypter + stub for .NET compiler like vb. net and c# using aes encryption & stub use runtime encryption techniques run all code on memory without on hard disks if you want contact me of course not for free
