Do not be fooled! PC Cleaner is a fake security program, which is part of a well-known computer scam. Applications like PC Cleaner are known as rogues, rogue security application or rogue defragmenters. Basically, programs like PC Cleaner pretend to be legitimate security programs, while actually causing a large number of problems on the infected computer system. While they advertise that they clean, or speed up your computer, in reality they do the complete opposite of what they promise. Rather than cleaning your computer system, PC Cleaner is a malware infection that will almost certainly cause your computer system to become slower, more unstable, and infected with other malware threats. PC Cleaner has a browser hijacking component that will force the victim to visit the PC Cleaner website constantly. Because of these characteristics, ESG malware researchers consider PC Cleaner a malware infection that should be dealt with as soon as possible.

Removing a PC Cleaner Infection from Your Computer

PC Cleaner cannot be removed through normal means. While other programs have a convenient uninstall button or can be removed through the Control Panel, it is nearly impossible to remove PC Cleaner through normal means. To remove PC Cleaner, it is necessary to undo the harmful changes PC Cleaner makes to your system settings and to the Windows Registry. Since PC Cleaner cannot be removed through normal means, an actual anti-malware program will be necessary to remove PC Cleaner. However, it is important to first bypass PC Cleaner's self-defense features. PC Cleaner can block legitimate security applications from launching and can also block certain websites associated with security programs. To prevent PC Cleaner from doing so, ESG PC security analysts recommend starting up Windows in Safe Mode. Safe Mode prevents PC Cleaner from launching, starting and stopping processes in the background.

PC Cleaner Seldom Attacks Alone

It is important to take into account that a malware like PC Cleaner seldom attacks alone. The presence of PC Cleaner on your computer is a sure sign of other Trojan infections being present. One particularly worrying situation is the association of PC Cleaner with several dangerous rootkits. Rootkits associated with PC Cleaner include the ZeroAccess rootkits. In these cases, ESG PC security researchers recommend using a specialized anti-rootkit tool to remove any rootkit infections, before attempting the removal of PC Cleaner. It is often almost impossible to remove PC Cleaner, unless its associated rootkit is removed.
