We had detailed posts on how to clean spywares and malwares from your PC. Here is another post on how to keep your registry clean and neat.
Why do you need Registry Cleaning software?
Registry Cleaners are designed to work on Windows operating Systems to detect any abnormalities in system registry and fix them safely. They quickly scan your system for unwanted or broken regsitry elements and report them via easy user interface. Based on the errors, they will either automatically clean them or ask your permission to do so. Sometimes there may be legitimate registry entries and are chances that they may be reported as broken. Luckily, all these software have Undo options. That is, they take automatic backup before deleting or cleaning registry entries and if you feel something is wrong after cleaning up the registry, you can always restore them. So, it is very important that you take backup before you do any tuning with the help of these tools.

Do Registry Cleaners always optimize the registry? Are they really needed?
Answer is yes. Whenever we install applications, they add too many registry entries and when we uninstall them not all of them are deleted. They keep hanging and slows down your PC performance. Even malwares are capable of leveling behind broken or suspicious registry elements. It is recommended that you run these tools once in a while.
