Enigma Virtual Box vs Themida

Enigma Virtual Box packages an application's files and registry into one executable for Windows. It is intended for creating portable applications and supports x86 32-bit and x64 64-bit binaries, including EXE, DLL and OCX formats. It can virtualize DLLs, ActiveX/COM objects, media and text files. Virtualized file operations are emulated in process memory, so temporary files are not extracted to the hard drive; virtual files can also be compressed to reduce the application's total size. ActiveX/COM components can be registered without administrator privileges. The maker says packaging requires no source-code changes: select the main executable, add files or directories, then process them. The download page lists version 11.30 as freeware with a size of 7.5 Mb, and the product page lists Windows 2000 through Windows 11. The maker cautions that the utility does not provide sufficient protection for virtualized files and recommends Enigma Protector for that purpose. It is free, with no registration or payment required.

Themida is Windows software that protects applications against advanced reverse engineering and cracking. Its SecureEngine technology combines anti-debugger, anti-disassembly, anti-tracing, anti-breakpoint, and anti-memory-patching techniques. Code protection options include virtualization, encryption, mutation, metamorphic scrambling, and random garbage-code insertion. It protects native 32-bit and 64-bit EXE files and dynamic libraries in DLL, OCX, and BPL formats. XBundler can embed DLLs and data files, while custom DLL plugins can be embedded in the protected binary. Integration is available through SDK communication with the protection layer and command-line support. Developers can customize dialog text and icons shown by protected applications. A demo is available for evaluation, but demo versions cannot be registered and have reduced protections, including light virtualization, no string encryption, and a demo splash screen. Licenses are perpetual. Developer License costs €249 as a one-time purchase; Company License costs €499 as a one-time purchase. Renewal plans cost 79.00 EUR or €159 a year for existing customers.
