Code:

[enable]

Globalalloc(keybd_zw,50)
Label(keybd_zw_f)
CreateThread(keybd_zw)
RegisterSymbol(keybd_zw_f)

keybd_zw:

pushad
popfd

push 1
call sleep

push 0
push 0
push 11
push #87
call USER32.keybd_event
push 0
push 2
push 11
push #87
call USER32.keybd_event

popfd
popad

cmp byte ptr [keybd_zw_f],1
jne keybd_zw

ret

keybd_zw_f:
db 0

[disable]

keybd_zw_f:
db 1

Automatically press w repeatedly, but the program will crash when writing in this way, help me!

32 bi. When calling call, you need to bring ret. However, createthread also needs ret. Do the two conflict?

You're pushing general purpose registers and popping them into the EFLAGS register.

You don't need to push or pop any non-volatile registers. Get rid of the push/pop ad/fd instructions.
