What is Registry Cleaner?

A registry cleaner is a piece of software that is specifically designed to clean up the Windows registry by deleting redundant, forgotten or useless data and files. However, these types of software can bring up a serious risk because they can allow harmful “malware” applications to easily access your registry, thus it make damaging changes. Both Registry Cleaner and Pcobserver registry cleaner are two names of a single rogue registry cleaning application that is malicious and can definitely infect the system with a screenlocker. Additionally, versions of Windows based on the NT build, which would  include XP, Vista, and Windows 7, are able to automate the upkeep of the registry and prevent it  from becoming bloated.
The rogue Registry Cleaner malware is promoted through the website registrycleaner.online./download-now though it can be distributed alongside freeware programs available on various freeware sharing websites as well. These fake antivirus programs  are basically programmed to deceive victims into convincing that their computers are heavily infected. What you should do is to ignore such warnings and  alerts of such programs and is basically applicable to Registry Cleaner malware.
The main concern to this issue is that it is powered to install a screenlocker. There exist different types of screenlocker which include the ransomware infections which encrypt or lock the files and ask for payment in return to gaining back their files unlocked or decrypted. Either aggressive infections or just screenlocker can do extensive damages and inconveniences.
Fortunately, malware researchers have come up with the code that will disable the screenlocker installed by the fake registry cleaner just by entering this code: 8716098676542789
There would be a prompt window pops up, and you should click OK to end the procedure of disabling the screenlocker, and by doing so, the infection is left  within the system but regain access to your folders and files, which is done because the explorer.exe process restarts.
Again, the Registry Cleaner can be bundled with free programs or from the third party programs, some of which may also need to be removed in order to ensure prevention of danger or possible threats. It is critically essential to check whether the program you are about to install is reliable, because you are at of risk being infected with malware programs such as screenlockers, Trojans, and other threats. The case with Registry Cleaner and the screenlocker discussed is not the most complicated, however, if you keep the system unprotected, your careless interaction with unreliable website may be the cause of further security issues which lead to extensive damage to your computer.
