What is Registry Cleaner?

As the name suggests, Registry Cleaner supposedly cleans and fixes the system registry. According to its developers, this program is also capable of boosting memory and cleaning junk files. Registry Cleaner may seem to be a legitimate program, however, it is malicious and a Trojan.Clicker used to perform 'click fraud'.

Registry Cleaner malware

Registry Cleaner is promoted by a dubious website that is made to seem legitimate and official. Once downloaded and installed, this registry cleaner/system optimizer runs the "EpizyCleanup" process in Task Manager, which is, in fact, the Trojan.Clicker process performing click fraud. This malicious program commits click fraud in an automated way. It can be used to click ads to generate revenue or drive up the costs of competitors' advertising campaigns. Making profits by fraudulently clicking ads in PPC (Pay-per-click) advertising or draining advertising budgets of competitors by increasing ad costs is illegal. Furthermore, publishers can use tools such as Trojan.Clicker to click website ads, thus making certain sites more attractive for others looking to place online ads. Click fraud is a big problem in PPC advertising business and tools such as Trojan.Clicker are used only for illegal purposes. Therefore, you should remove this malware, which is disguised as Registry Cleaner.

There are many other programs created to generate revenue by operating as Trojan.Clicker. These malicious programs are disguised as Registry Mechanic, Microsoft Cleaner, Registry Doctor, or other programs. People download and install them intentionally, expecting them to be system optimization programs, however, they do not fix any problems and provide users with fake lists of so-called 'detected issues'.

How did Registry Cleaner infiltrate my computer?

Cyber criminals proliferate malware in different ways - usually they employ spam campaigns, untrustworthy software download sources, trojans, software 'cracking' tools, and fake updaters/update tools. To proliferate malicious programs through spam campaigns, they send emails that contain malicious attachments. The purpose of spam campaigns is to trick people into opening these files, which then download and install other viruses. Attached files could be Microsoft Office documents (Word, Excel and others), executables (.exe files), archives (RAR, ZIP and similar), JavaScript files and so on. Another way to proliferate infections is through dubious software download sources such as Peer-to-Peer networks, freeware download websites, free file hosting websites and so on. Cyber criminals present their malicious executables as legitimate files. People who download and open them install malware. Trojans proliferate other viruses. If these programs are installed, they infect computers with other malicious programs. Software 'cracking' tools are used by people who do not want to pay for software, however, using these tools risks installation of malicious programs. Cyber criminals also use them to proliferate viruses. Fake software updaters usually infect systems by exploiting outdated software bugs/flaws or by downloading malware rather than the expected updates and fixes.

How to avoid installation of malware?

Avoid opening attachments or links that are presented in irrelevant emails sent from unknown/suspicious email addresses. Bear in mind that these emails are usually designed to appear official and important. Download software from official pages and using direct download links. All other, dubious sources might be used to promote unwanted or malicious programs. Update software with tools or implemented functions that are provided by official software developers. Activate all software properly, without using third party ('cracking') tools. These are illegal and might cause serious damage (computer infections). Finally, have reputable anti-virus or anti-spyware software installed and keep it enabled at all times. This prevents viruses from causing damage to computer systems. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
