Unregistering Malicious DLL Files
The DLL files
DLLs (Dynamically Linked Library files) contain a list of functions that are used by various programs. Usually DLLs carry the essential information which is needed for the system to function properly. If one or several DLL files are corrupt or missing it may stop your computer from working or might even cause a system crash.
Why malicious DLLs should be unregistered
Malicious programs may damage or replace the regular DLL files so that removing them would harm the computer. If a false DLL is used by a legitimate program and the file is removed by the user, the software might become unusable no matter whether the DLL was vital for the program or not. So it is very important to unregister DLL files before removing them. Deleting DLL files manually involves a high amount of risk therefore we strongly recommend using a legitimate system security software. However, if you want to remove the malicious files yourself you should follow the bellow instructions.
Unregistering malicious DLL files
Open Command Prompt window

Go to Start menu and select Run process. Type in cmd and click OK
Unregister malicious DLL
Type regsvr32 /u filename.dll (filename.dll should contain the name of the file you want to unregister) into the Comand Prompt window and press Enter.
