PC Regcleaners Virus

Also Known As: PC Regcleaners Trojan.Clicker
Type: Trojan
Damage level: Severe

What is PC Regcleaners?

PC Regcleaners (other known variants are named Regcleanerz and Regcleaners) is promoted as a system/computer optimization program that supposedly cleans computers and enables them to start faster.

According to the developers, it includes tools such as a registry cleaner, memory booster, and junk cleaner. In fact, after installation, it runs as a Trojan.Clicker, a tool used to engage in 'click fraud'.

PC Regcleaners malware

Like other programs of this type, PC Regcleaners is presented as a legitimate program which can be downloaded from a supposedly official website. Once downloaded and installed, it starts running the Trojan.Clicker, which is disguised as the "EpizyCleanup" process in Task Manager (see screenshot above). This is a malicious program used to perform click fraud.

Click fraud is illegal. Its purpose is to click Pay-per-click (PPC) advertisements to generate revenue or drain advertisers' budgets. It can be performed manually or automatically (in this case, the latter). People use the Trojan.Clicker malicious program to click their own ads or those of competitors. They use it to earn revenue or to cause increased cost of advertising for their competitors.

For example, if a competitor has a limited budget, funds might run out quickly and thus will stop receiving clicks on ads. Another way to generate revenue from click fraud is to click ads displayed on an owned website, thereby making it more attractive for other advertisers.

In any case, those who use programs such as Trojan.Clicker are performing illegal actions. For this reason, we recommend that you uninstall PC Regcleaners immediately.

PC Regcleaners is not the only program that is used to trick people into installing Trojan.Clicker. Other examples are Registry Cleaner, Registry Mechanic, and Microsoft Cleaner.

These programs are presented as system optimization tools, however, they can also provide fake results (detect non-existent problems) - they do not fix any issues and are designed only to generate revenue for the developers by performing illegal actions.

How did PC Regcleaners infiltrate my computer?

PC Regcleaners developers promote this app using a dubious website, however, there are other ways to distribute malicious programs. For example, using spam campaigns, trojans, other dubious software download sources, fake software updating and software 'cracking' tools.

To proliferate malware through spam campaigns, cyber criminals send emails that contain attachments such as Microsoft Office or PDF documents, archives (ZIP, RAR and other files), JavaScript, executable files, and so on. Their goal is to trick unsuspecting people into opening these attachments. If opened, they download and install malicious software.

Trojans are malicious programs that are used to cause chain infections. If installed, they cause download and installation of other malware. Various freeware download, free file hosting websites, Peer-to-Peer networks (torrent clients, eMule) are often used to present infected files as legitimate.

People who use these sources download various files and software risk installation of malicious programs. Fake software updating tools cause computer infections by downloading and installing malware rather than the promised updates, or by exploiting outdated software bugs/flaws.

Various software 'cracking' tools have similar behavior. They supposedly activate software (illegally), however, they simply infect computers with high-risk viruses.

How to avoid installation of malware?

To keep computers safe and prevent them from being infected with malicious programs, we recommend that you download, install, update software and browse the Internet with care. Do not use third party software downloaders (or installers), dubious sites, or other similar web pages. Download from official and trustworthy websites and using direct download links.

Update installed software (or operating systems) using implemented functions or tools provided by official software developers, and not unofficial tools. Do not open attachments that are presented in irrelevant emails received from unknown, suspicious addresses. The same applies to web links. Ignore these emails and leave their contents unopened.

Do not activate software using 'cracking' tools. Many cause download and installation of malware. Furthermore, it is illegal to use these programs to bypass software activation.

Have reputable anti-spyware or anti-virus software installed and enabled. These programs can protect computers from various threats. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. 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 Combo Cleaner Antivirus for Windows.
