PEtite

Created the Sunday 19 June 2022. Updated 1 year, 1 month ago.

Petite is a free Win32 (Windows 95/98/2000/NT/XP/Vista/7/etc) executable (EXE/DLL/etc) compressor. The compressed executables decompress themselves at run time and can be used just like the original non-compressed versions.

Petite also adds virus detection to the compressed executables; they will check themselves for infection every time they are executed.
