Avoid installation of a click fraud tool disguised as Registry Doc

Also Known As: RegistryDoc unwanted application
Type: Trojan
Damage level: Medium

What is Registry Doc?

RegistryDoc (or Registry Doc) is software that supposedly improves computer performance, removes junk files, fixes the registry, optimizes browsers, and allows quicker access to files. In fact, this program is classified as a potentially unwanted application (PUA), since developers distribute it using deceptive methods.

Therefore, people usually install programs such as RegistryDoc unintentionally. Furthermore, RegistryDoc operates as a Trojan.Clicker, a malicious program that performs 'click fraud'.

Registry Doc malware

Typically, when programs that perform click fraud are installed, they connect to various websites and fraudulently enforce clicks on links and advertisements. Cyber criminals trick people into installing these programs so that they can use their computers to generate revenue through the PPC (pay-per-click) model.

Click fraud is illegal. To avoid being part of it, uninstall the Trojan.Clicker malicious program, which is disguised as RegistryDoc, immediately. As mentioned, RegistryDoc supposedly improves computer performance, fixes the registry, and so on, however, issues detected by this software are often fake (and thus it does not fix any issues).

The main goal of RegistryDoc developers is to trick people into having this program installed as long as possible so that they can generate more revenue from click fraud.

RegistryDoc is very similar to Registry Doctor. Both are disguised as legitimate and useful programs, however, programs that perform click fraud are illegal and should never be used. Therefore, Registry Doctor, RegistryDoc, and other programs that perform illegal actions, should be uninstalled immediately.

How did Registry Doc infiltrate my computer?

RegistryDoc is commonly advertised on a dubious, supposedly official website, however, it can also be downloaded via other channels such as Peer-to-Peer networks (torrent clients, eMule), freeware or free file hosting websites, and third party downloaders.

cyber criminals often use these sources to trick people into downloading and installing malicious software that is disguised as useful, harmless, legitimate, etc. Furthermore, programs of this kind can be distributed through emails. Cyber criminals often send emails that contain malicious attachments and attempt to trick people into opening them.

When opened, they install unwanted, malicious programs. Examples of files that they attach to their emails are Microsoft Office, PDF documents, JavaScript files, archive files such as ZIP, RAR, executable files such as .exe, and so on. Trojans are also used to distribute malicious software.

When installed, they usually download and install malware (thereby causing chain infections). Fake software update tools install malicious programs rather than updating installed software or exploit bugs/flaws of vulnerable, outdated software. Using unofficial software activation tools can also lead to installation of malware.

These tools supposedly bypass paid software activation, however, they often download and install malicious software.

How to avoid installation of malware?

Do not download programs or files from dubious sources. The safest way to download is using official websites and direct download links. Received emails that are irrelevant, contain attachments (or web links) or sent from suspicious, unknown addresses should not be trusted.

Do not open files attached to them. All software should be activated and updated properly through tools designed by official software developers. Do not use third party, unofficial tools. It is illegal to activate software using 'cracking' or other unofficial programs. If a download or installation setup contains offers to download or install additional software, dismiss them.

Typically, these offers can be found in setup options such as "Custom", "Advanced", and so on.

Finally, scan the operating system with reputable anti-virus or anti-spyware software and eliminate all detected threats immediately. 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.
