How Can You Tell if a Registry Entry is Legitimate?

The registry is a complex structure and that can be corrupted by malicious programs, which can modify key values and create new values. Malicious programs such as spyware can have its code operate automatically; therefore, it often has a negative effect on other legitimate software.

Safe registry entries are created by legitimate software applications and the Windows operating system. The Windows operating system is composed of a huge hierarchical database called a registry. The Windows Registry holds configuration settings and options for the operating system and installed programs, which is vital for the basic operation of a PC and should be handled with extreme care.

Registry entries are split into a number of different logical sections mostly dependent on the type of function it performs. Safe registry entries and malicious registry entries may look similar in some instances, which is why it is important to determine the difference using our registry database.

Some Windows system files and registry files should not be modified. However, some
registry keys, INI files and other type of files are regularly modified by legitimate programs. For example: the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run Registry key is a usually targeted by spyware authors, but Microsoft isn't able to block applications from modifying this registry key because some programs (e.g., anti-spyware programs) legitimately change the key. If you're not sure about the legitimacy of a registry key or entry, check for registry keys with an anti-spyware program.

The Effects of Malware on a Windows Registry

Malware registry entries are created to modify the behavior of an infected PC. Malware can make modifications to the Windows Registry to either delete, hide, or add registry entries in a system. Once a Windows Registry has been infected with malware, it can be manipulated to run malicious files every time a machine restarts and to perform other malicious functions such as changing settings on the Internet Explorer. Removal of malware registry entries is essential to rid a system of malware files or a malicious program.

The Windows Registry is a large hierarchical database full of instruction code that software applications rely on for successful operation and directions. When the registry becomes populated with malware registry entries, it could adversely affect system behavior, stability and possibly allow additional malware to be installed. Depending on the type of malware installed on an infected system, the number of malware registry entries populating the Windows registry may vary.
