What is Webmoka PC Cleaner?

Webmoka PC Cleaner is advertised as system optimization software that improves computer performance, fixes the registry, removes junk files, optimizes browsers, and so on. This may seem to be a legitimate tool that contains useful features, however, Webmoka PC Cleaner is a Trojan.

Clicker, a malicious program that performs 'click fraud'. Tools of this type are illegal and, therefore, we strongly recommend that you uninstall Webmoka PC Cleaner immediately.

Webmoka PC Cleaner supposedly allows people to scan their systems for various errors, issues, and other problems. Once fixed/resolved, this apparently improves computer performance, however, it is likely that Webmoka PC Cleaner does not fix any issues and simply displays fake scan results.

The cyber criminals who distribute this program aim to make people believe that Webmoka PC Cleaner is a legitimate and useful tool. The longer it is installed, the more revenue they can generate. As mentioned, this tool stealthily performs illegal activity known as click fraud.

Cyber criminals generate revenue through Webmoka PC Cleaner (Trojan.Clicker) when it performs click fraud on users' computers: by forcibly clicking links and ads on various web pages. This software helps criminals to fraudulently generate revenue though the Pay-Per-Click (PPC) model.

Note, click fraud is illegal and, therefore, Webmoka PC Cleaner, and other click fraud tools, should be uninstalled immediately.

Webmoka PC Cleaner is similar to Registry Doctor and Registry Doc. No matter what differences these programs have, all are disguised as useful and legitimate software. In fact, they are malicious programs that function as click fraud tools. To prevent your computer from being used to perform this type of fraud, uninstall Webmoka PC Cleaner immediately.

How did Webmoka PC Cleaner infiltrate my computer?

Webmoka PC Cleaner is advertised and available on its download website, however, there are also other ways to distribute unwanted (and malicious) programs. For example, through spam campaigns, trojans, other untrustworthy software download sources, fake (unofficial) software updaters and 'cracking' tools.

To distribute malware or other unwanted software through spam campaigns, cyber criminals send emails that contain attachments. If opened, these download and install malicious software.

Some examples of files usually attached to emails of this type include MS Office documents, JavaScript files, PDF documents, archives such as ZIP, RAR, executable files such as .exe, etc. Trojans are malicious programs that cause chain infections. When a trojan is installed, additional malware is installed.

More examples of untrustworthy software download channels are free file hosting sites, Peer-to-Peer networks such as eMule, torrent clients, third party downloaders, and so on. Cyber criminals use these channels to trick people into downloading and installing malicious software by presenting infected files as legitimate, useful, etc.

Fake software updaters cause damage by exploiting bugs/flaws of outdated software that is installed on the system, or by downloading and installing malware rather than updates. Software 'cracking' tools have similar behavior: they supposedly allow users to activate programs free of charge (illegally), however, they often download and install malicious programs.

How to avoid installation of malware?

Do not open emails that contain attachments or are received from unknown, suspicious addresses (at least not without inspecting them first). Software should not be downloaded or installed using third party downloaders, installers, unofficial websites, or the other sources mentioned above.

The safest way to download is using official web pages and direct download links. Additionally, software should updated properly using tools provided by official software developers, and NOT third party updaters. Use of various software 'cracking' tools is a cyber crime and can cause computer infections.

Finally, have reputable anti-virus or anti-spyware software installed and scan the operating system with it regularly. 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.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically.

To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

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.
