Cheetah keystroke logger removal guide
What is Cheetah keylogger?
Cheetah is a keylogger (keystroke logger), which is sold for $30/month, $65/three months, and $110/year. Software of this type records keys pressed on the keyboard (keyboard input). Typically, cyber criminals attempt to trick people installing keyloggers on their computers so that they can steal their personal, sensitive information, which is then used to generate revenue in various ways. If you believe that Cheetah (or another program of this type) is installed on the operating system, remove it immediately.
There are many keyloggers (including legitimate programs) on the internet, however, this software is often misused by cyber criminals to steal personal, sensitive information. For example, login credentials, passwords and other confidential details. Cyber criminals commonly target cryptocurrency wallets, banking, email, social media and other accounts, clipboard data, and so on. Stolen information can be misused to make fraudulent purchases and transactions, hijack accounts to proliferate other malware (e.g., Trojans, ransomware), trick other people into transferring money, and so on. A keylogger such as Cheetah is a serious threat to victims' personal data and can cause problems such as identity theft, monetary loss, serious privacy issues, and other issues. Unfortunately, victims are often unaware that they have a keylogger installed on the operating system and that their actions are being monitored. Therefore, to prevent installation of software such as Cheetah, it is important to take certain precautions. If you suspect that this, or other, similar software is already installed on your computer, eliminate it immediately.

How to avoid installation of malware
Do not open attachments or web links that are included in irrelevant emails, especially if they are sent from unknown, suspicious addresses. These emails should be carefully studied. If there is reason to believe that an email might be sent by criminals, ignore it and leave it (and attachments) unopened. All files and programs should be downloaded from official and trustworthy websites. Unofficial websites, various third party downloaders, installers and other channels (mentioned above) should not be used. Software must be updated and activated via implemented functions and tools designed by official developers. Third party tools can infect computers with malware. Note that it is illegal to activate software with unofficial tools. Keep your computer safe by regularly scanning for threats with reputable antivirus or anti-spyware software and remove 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.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "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 Combo Cleaner Antivirus for Windows.
