[HELP] Spreading Payload/Virus Through Wifi or by Just Inserting a USB Stick

Hello guys

I wanted to know if I can spread my payload/virus through wifi and running it on an another computer.

and Also, I wanted to know if I can run my payload or virus right after a USB stick is inserted, without using the autorun thingy..

if there are ways for these 2 things I asked for, can anyone please link a tutorial? or tell me here ?

Thanks in forward <3
