How to Make Persistence Backdoor Windows 10 or 7 Av Bypass Like Kaspersky,Avast and Norton?
Well, if you don't want to raise any alarms, make the backdoor yourself using whatever programming language you find best. I recommend Python. Antiviruses will have a hard time detecting your backdoor that way. Due to the fact that you are hacking a machine running Windows, I suggest converting the .py file (assuming you are using Python) to a .exe file (using something like py2exe).
For persistence, you have a couple of options including placing it in the startup folder of the PC, using Task Scheduler to launch the backdoor, or adding the backdoor to the registry so it starts on boot.
