What is Registry Doctor?

Registry Doctor is a program which supposed to operate as a system optimization tool. It is promoted as a tool that removes junk files, fixes registry, optimizes browsers and improves overall computer's performance. However, it is also known as Trojan.Clicker, a malicious program which is designed to perform click fraud. Simply said, Trojan.Clicker is disguised as Registry Doctor, a supposedly legitimate and useful software.

Registry Doctor malware

Registry Doctor/Trojan.Clicker is promoted on some questionable website. Once downloaded and installed, it starts a malicious process in Task Manager called "EpizyCleanup". It might look like a legitimate process, however, by running in the system's background it performs the aforementioned click fraud. It connects to various websites and clicks links, and advertisements. Simply said, by clicking various ads it generates revenue for cyber criminals through the Pay-per-click (PPC) model. It is illegal to generate revenue in such ways (using the click fraud method). If there is any reason to believe that this Trojan.Clicker (disguised as Registry Doctor) malicious program is installed on the computer, it should be removed as soon as possible. Besides, it is very likely that the Registry Doctor is not an actual system optimization tool - it only detects issues (probably fake ones) but does not fix any of them. It is designed to give an impression that it is effective so that people would not uninstall it shortly after installation and would keep it installed for a long time. Keeping it installed keeps Trojan.Clicker installed as well, which allows cyber criminals to generate revenue as long as it is not uninstalled.

There are many various malicious programs that are disguised as legitimate and useful software. Some of them might be designed to cause computer infections, steal personal, confidential details, control computers remotely and so on. Typically, programs of this type get installed when people use carelessly browse, use questionable software or sources to download it.

How did Registry Doctor infiltrate my computer?

One way to download and install Registry Doctor/Trojan.Clicker is through some untrustworthy website. It is quite a common way to distribute malware. Some examples of other sources that can be used to achieve this are: Peer-to-Peer networks (eMule, torrent clients and so on), free file hosting and freeware download websites and other similar sources. Simply said, cyber criminals use them to present dubious files as harmless/legitimate. Other ways to proliferate malware are using spam email campaigns, fake software updaters, trojans and software 'cracking' tools. Spam campaigns are used to proliferate malware through email attachments. These attachments usually are Microsoft Office documents or PDF documents, archive files like ZIP, RAR, executables (.exe and other files), JavaScript files and so on. If opened, they cause installations of various malicious software. Fake software updaters might download/install unwanted software by exploiting bugs and flaws of already installed but outdated software, by downloading and installing malware instead of the updates. Trojans are designed to cause chain infections. Once (and if) downloaded and installed, they spread unwanted, malicious programs. One more way to infect computer with malware is by using software 'cracking' tools that supposed to bypass paid software activations. These programs are often designed to download various unwanted/malicious programs too.

How to avoid installation of malware?

Do not open attachments (or web links) presented in irrelevant emails without carefully analyzing them first. If such email is received from a suspicious, unknown email address, it is better to keep its contents unopened. Furthermore, it is important to download all software from official websites (or other trustworthy sources) only. Every download/installation should be handled properly, it means that any software's setups should be analyzed and their "Custom", "Advanced" settings, options should be checked. If there are any offers to download/install unwanted apps, they should be dismissed. One more crucial thing is to update installed software via implemented functions or tools that are provided by official software developers. Other tools might cause installations of malicious programs. And finally, we strongly recommend to have a reputable anti-virus or anti-spyware suite installed and always enabled. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
