First there was antivirus software, and then came the wave of spyware and malware application all offering you protection from the dangers of the internet. All very necessary tools, as experts might add but what about registry cleaners?

A registry cleaner is a Windows software utility that removes configuration data from the Windows registry that are no longer in use.

When it comes to choosing Registry Cleaners, you can find authentic software (that is if you add and remove programs from your system often) however, there are several options that are associated with malware and scareware which warn you of ‘critical’ errors when there are none while some use website pop-ups to sell their product, appropriately known as rogue registry cleaners.

The latter has caused a lot of controversy and experts are skeptical not only of its requirement for optimum performance but also question the fact if authentic software is actually available or not. At the most, experts say that it frees up a few kilobytes of RAM, while on the other hand it can be dangerous in the hands of a computer novice causing system instability and loss of functionality as well.

So, in other words, there are more ‘cons’ than pros when it comes to the use of Registry Cleaners, and one should be extremely careful when choosing this kind of software for your computer. It is advisable that you take the recommendation of a computer technician before proceeding to purchase any Registry software from the internet, as some of them delete information that is still being used by the Windows operating systems.
