Manual removal of malicious registry entries

The registry is one of the most vital components of the Microsoft Windows operating system. In simple phrase, it is a complex database containing virtually all system, software, hardware and user settings. Almost every piece of software keeps its data in the registry. It is so important, that Windows would not even start without it.

The major part of all dangerous parasites, especially browser hijackers, trojans, spyware and adware threats modify the Windows registry. Parasites add various registry entries, create new keys, change default values. This is made in attempt to register a pest in the system, alter essential settings of the Windows operating system and installed software. Most of such changes are made for malicious purpose.

On our site you can find parasite registry entries that need to be manually removed. However, editing the registry is a difficult task that only advanced users and professionals can accomplish safely. Most anti-spyware programs will remove malicious registry entries for you. However, even the most powerful spyware removers might be unable to get rid of certain threats. The reason is simple: security software vendors cannot examine each recent pest immediately after it goes wild, and new pests appear almost every day. Anti-spyware tools rely on spyware definition databases. A few advanced products can find unknown suspicious files, but unknown harmful registry entries often stay unrecognized. This is why you need to know how to manually edit the Windows registry. But you have to be extremely careful. One inappropriate value, mistyped registry key or other small mistake in the registry may damage installed software and even corrupt the entire system! Do not modify the registry if there is no real need for this!

The following guide thoroughly explains how to manually remove malicious registry entries.

Back up the Windows registry before editing it, so that you can quickly restore it later if something goes wrong. Please read the article Backing up and restoring the Windows registry to learn more. Remember, this step is very important!

Launch the Registry Editor. Press the Start button and then click Run. Type in regedit into the Open: field. Then click on the OK button.

    In my opinion it is an excellent set of instructions on how to use the Registry Editor. It however does NOT explain what the individual registry entries are, what they do, or what they should or should not look like.
