Gh0st virus removal guide
What is Gh0st?
Gh0st is remote access/administration tool (RAT) used to control infected Windows computers remotely. Gh0st is installed on computers through other malware that opens a 'backdoor'. This allows cyber criminals to control the infected computers. RATs can be used for a number of purposes, however, when misused by criminals, many cause serious problems relating to privacy, finances, etc.
RATs are sometimes used to access the victim's microphone and webcam, and to log keystrokes. Some variants of Gh0st can be used to install cryptocurrency miners and/or various trojan-type programs. The keystroke logging feature helps cyber criminals to log keystrokes. I.e., record keys pressed on the keyboard. Using this data, cyber criminals can steal credentials such as logins and passwords of various accounts. They might gain access to banking or email accounts, Facebook, Telegram, and so on. Stolen accounts can be used to make fraudulent transactions, purchases, extort money from other people, send scam/spam campaigns, etc. Furthermore, Gh0st might be used to install a cryptocurrency miner on infected systems and use computer hardware to mine a cryptocurrency (by solving mathematical problems). Typically, these programs cause high CPU and/or GPU usage, which leads to higher electricity consumption use and diminished computer performance. People who have cryptocurrency miners installed on their computers receive higher electricity bills, experience unexpected shutdowns, hardware overheating, and other issues. Cyber criminals can use Gh0st to infect computers with various Trojans. Examples of trojan-type programs are Nymeria, Retefe, Vigorf, and so on. They might be designed to distribute other malware such as information stealers, ransomware, and other, high-risk viruses. To avoid potential damage that can be caused by Gh0st, we recommend that you uninstall it immediately.

There are many RATs on the internet. Some examples are Quasar, CyberGate, and Sakula. Generally, cyber criminals seek to infect systems with these programs so that they can control the victim's computer remotely and perform actions that might help them to generate revenue in various ways. If there is any reason to believe that your computer is infected with RAT, remove it immediately.

How to avoid installation of malware
Files that are attached to irrelevant emails should not be opened. Typically, these emails are sent from unknown addresses and disguised as important, official, and so on. Installed programs must be updated using tools or functions that are designed by official developers. If activation of installed software is not free, it should be performed correctly. Various 'cracking' tools should not be used, since they are often used to proliferate malware. It is also illegal to activate licensed programs with cracks. All programs and files should be downloaded from official websites and via direct download links. Other channels often contain malicious files and are used to distribute malicious software. Diminish the risk of system infection by regularly scanning your computer with a reputable anti-virus or anti-spyware suite (software of this type should be kept up-to-date). If you believe that your computer is already infected, we recommend running a scan with Malwarebytes 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 Malwarebytes for Windows.
