Registry Doctor virus removal guide
What is Registry Doctor?
Registry Doctor is a program designed to operate as a system optimization tool. It supposedly removes junk files, fixes the registry, optimizes browsers, and improves overall computer performance, however, it is also known as Trojan.Clicker, a malicious program that performs 'click fraud'. In summary, Trojan.Clicker is disguised as Registry Doctor, supposedly legitimate and useful software.
Registry Doctor/Trojan.Clicker is promoted on a dubious website. Once downloaded and installed, it starts a malicious process in Task Manager called "EpizyCleanup". This may seem to be a legitimate process, however, when running in the system background, it performs click fraud - it connects to various websites and stealthily clicks links and advertisements. By clicking ads, this program generates revenue for cyber criminals through the Pay-per-click (PPC) model. Note that it is illegal to generate revenue 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 your computer, it should be removed immediately. Registry Doctor is unlikely to be a legitimate system optimization tool - it simply detects 'issues' (probably fake) and does not fix them. The program gives the impression that it is effective software so that people keep it installed on their systems. This, however, also keeps Trojan.Clicker installed, which in turn allows cyber criminals to generate revenue.

How to avoid installation of malware?
Do not open attachments (or web links) presented in irrelevant emails without carefully analyzing them first. If such an email is received from a suspicious, unknown email address, leave the contents unopened. Download all software from official websites (or other trustworthy sources) only. Each download/installation should be handled properly. Study software setups and check "Custom", "Advanced" settings and options. If there are any offers to download/install unwanted apps, they should be dismissed. Update installed software via implemented functions or tools provided by official software developers. Other tools might cause installation of malicious programs. Have a reputable anti-virus or anti-spyware suite installed and enabled. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check 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".
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.
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.
