Decompiling EXE to ASM

antivirus, assembly, disassembly

Solution

You can install Cygwin and use objdump to decompile an exe into asm. Be sure you select the binutils when installing cygwin. After installing cygwin, you can run the following from a bash shell:

objdump -Slx yourpgm.exe

Problem

I want to make a basic antivirus for my free time. Basically I learned about the basic structure of the EXE(windows) file. How do I extract the ASM code from the file and the PE header?
