About DLL

DLL, short for Dynamic-link library, is Microsoft’s implementation of the shared library concept in the Microsoft Windows. These libraries usually have the file extension DLL, OCX (for libraries containing ActiveX controls), or DRV (for legacy system drivers).

DLL is a kind of well compiled code. There is not big difference between DLL and other general procedures except that DLL cannot run independently. They need to be called by a procedure. The difference between DLL code and other programs is just a different interface and start-up mode. If you change its code entry, a DLL will be transferred into a separate program. Actually, there is no program logic in DLL files,. Here I am not saying a DLL is the same as an EXE. You can regard DLL as an EXE without the main entrance of EXE. The functions of DLL can be seen as several function modules of a program. To add some special code to a code with the function of the Trojan, you will get a DLL Trojan. This is what is called DLL Trojans.

Since DLLs are very essential, the choice of which to produce as part of the linking process is for clarity. It is not possible to execute a DLL directly, since it requires an EXE for the operating system to load it through an entry point, hence the existence of utilities like RUNDLL.EXE or RUNDLL32.EXE which provide the entry point and minimal framework for DLLs that contain enough functionality to execute without much support.

DLL missing can cause many problems

If you lose a DLL, these errors may keep your computer from working well.

1. You can’t open an online game
2. There is no sound on your computer
3. Blue screen
4. The desktop cannot be displayed
5. The home page is modified to site classification navigation
