If you write software in VB, you can increase protection against decompilation. The decompiler contains an obfuscator that can delete the names of all functions, forms, modules and objects and all kinds of signatures from the EXE file. It will make analyzing the program with this decompiler difficult and other decompilers will refuse to decompile this file at all. To do it, you should open your program in the decompiler and select the Obfuscate project in the Tools menu. This procedure doesn't take much time that's why it is recommended to obfuscate programs before releasing them.
