*Is This Possible?*

[facun20]

Is there a way to know exactly each line of code a program is running? Let's say for example I wanted to know all the lines of code Norton Antivirus is running and what commands and functions it has, would I be able to do such thing?

If you do have both the code and a binary with debug symbols, then a debugger can link/show code as program executes.

If you don't ... you can disassemple binary into something, but ...

"very sleepy" don't show you exactly the code lines, buts the functions has been called!
