What is Registry Mechanic?

The Registry Mechanic program supposedly allows computers to run faster and also cleans them. According to the developers, it can improve computer performance by removing junk files, fixing and cleaning the registry, and optimizing browsers. In fact, this is a malicious program known as Trojan.Clicker, a tool used for 'click fraud'. Registry Mechanic is simply a name used to disguise the real purpose of this program.

More about Registry Mechanic

This malicious program can be downloaded from a website that may seem legitimate and official, however, legitimate websites do not promote malware. When installed, Registry Mechanic starts a background process that can be identified as "EpizyCleanup" in Task Manger.

This process is a disguised Trojan.Clicker that performs click fraud, however, in some cases, this malicious program could be used to proliferate other computer infections. Click fraud is an illegal way to generate revenue on the Internet through PPC (Pay-per-click) advertising.

In summary, programs such as Trojan.Clicker imitate legitimate advertisement clicks and generate traffic to various sites. The more ads they click, the greater revenue they generate for hosts of websites on which these ads are displayed. They can drain an advertiser's budget by increasing the cost of advertising.

Therefore, an advertiser might use this technique to sabotage their competitors. Clicks generated by programs such as Trojan.Clicker are illegal and, therefore, should not be used. In many cases, people are unaware that they have such a program running on their systems and unintentionally help fraudsters to generate revenue.

In this case, people who have installed the Registry Mechanic program on their computers unintentionally help fraudsters.

Registry Mechanic is not the only program operates as Trojan.Clicker malware. A number of other examples are Microsoft Cleaner and Registry Doctor. Generally, these programs are promoted using deceptive methods - in this case, through a deceptive website that seems official.

We strongly advise that you ensure that all programs are legitimate before downloading and installing them.

How did Registry Mechanic infiltrate my computer?

In addition to unofficial pages, malicious programs can be proliferated using other dubious software download sources such as Peer-to-Peer networks (torrent clients, eMule etc), free file hosting or freeware download websites, third party downloaders and other similar channels.

Other deceptive ways to distribute malicious programs are spam campaigns, trojans, fake updating and software 'cracking' tools. Cyber criminals use spam campaigns to proliferate their viruses by sending emails with files attached to them.

These attachments are usually Microsoft Office documents, PDF docs, archives such as RAR, ZIP, executables (i.e., .exe files), JavaScript files, and so on. If opened, these files cause download and installation of high-risk malware. Trojans are malicious programs that proliferate other programs of this kind - they cause chain infections.

To do this, however, they must first be installed. Fake software updaters exploit outdated software flaws/bugs or download and install malicious programs rather than fixes or updates.

People who use software 'cracking' tools to avoid having to purchase installed software (pay for activation) often unintentionally allow these tools to download and install malware. Therefore, cyber criminals often employ them to proliferate viruses.

How to avoid installation of malware?

Browse the web, install, download and update software properly. Do not open attachments that are presented in irrelevant/dubious emails received from unknown email addresses. The same applies to web links presented in them.

Keep installed software updated, however, use implemented functions or tools provided by official developers, and not third party tools. All software should be downloaded from official websites and using direct links. None of the sources mentioned above can be trusted.

The same applies to software 'cracking' tools - using them is illegal and they are often used by cyber criminals who attempt to trick people into downloading/installing malware. Finally, have reputable anti-spyware or anti-virus software installed and to ensure that it is enabled.

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.

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.
