Anti-Virus/Anti-Spyware – Two types of software utilities that rid your computer, respectively, of viruses and spyware, both common causes of DLL errors.
Bridge DLL – Often associated with spyware and adware, this is a file extension for a parasitic program which attaches to other files making it quite difficult to remove and which can then be used to steal information from the infected PC.
Corrupt DLL – This is when a DLL file becomes damaged due either to:
• an incomplete or improper installation or uninstall of a particular application
• a faulty attempt to move, delete, fix, or otherwise alter a DLL file
• or the inadvertent and unwitting downloading of spyware, a virus, or other malware.
DLL (Dynamic Link Library) – A DLL file is a collection of instructions that an application can call upon for performing various routine procedures.
DLL Hell – This is a common colloquialism referring to almost any DLL problem, generally caused when:
• loading or closing one application causes another application to “break”
• newly installed DLL files aren’t backwards compatible
• DLL files are removed or unregistered following a program uninstall.
General Protection Fault (GPF) – This is when you are prompted to shut down an unresponsive application or your system shuts it down automatically, indicated by an error message that includes the following information: “PROGRAM NAME has performed an illegal operation and will be shut down”. It typically occurs because a particular DDL file no longer resides at the location in question, and is a failsafe measure that Windows takes to avoid a total system crash. You are then forced to shut down the application, or it will be automatically closed down.
Malware – Any malicious program that is installed on your PC unbeknownst to you, most often by way of being bundled with other software that you intentionally download. Many DLL errors are caused by malware infections on your PC. The most common and familiar forms of malware are spyware, adware, and viruses.
REGEDIT – This is the registry editor built into Microsoft Windows and can be used to manually fix a variety of computer errors, including DLL errors.
Registry Cleaner/Registry Repair Program – Numerous software applications exist that can both clean and repair your Windows Registry, thereby fixing and eliminating (among other errors) all DLL errors present at the time.
Rundll Error/Rundll32 Error – any of a vast number of errors that occur when trying to execute a particular application that requires calling up one or more DLL files using the Rundll.exe Windows system process. Whether you get a Rundll error or a Rundll32 error depends simply on what version of Windows your system has installed, but they mean the same thing.
