What is the ‘CleanThis’ Rogue Security Application and How to Remove CleanThis

It is bad enough that the economic conditions around the world are not the best but somehow hackers want to keep people down by spreading illicit security programs such as the newly discovered ‘CleanThis’ application. CleanThis (Clean This) has been discovered by security researchers to be a fake anti-virus program that resembles the legitimate HijackThis program developed by security company TrendMicro.

Computer users who have encountered CleanThis have reported several instances where CleanThis has eliminated the ability for them to simply access their desktop. Additionally, CleanThis has been found to lead users to a purchase page that asks for credit card information to begin the process of buying a full version of the CleanThis program. It has been confirmed that a full version of CleanThis does no more than the free one that is usually installed through a Trojan horse download. CleanThis will pretend that it can detect and remove viruses and other malware on a PC but it will not even if you purchase a ‘full-version’.

How Can You Remove CleanThis?

CleanThis can be very difficult to manually remove if you are an inexperienced computer user. Not to mention, CleanThis has been known to populate the Windows Registry with many different entries and removing the wrong entries could render a PC damaged or useless.
