Conhost.exe virus removal guide
What is Conhost.exe?
Conhost.exe (Console Window Host) is the process of a program (cryptominer) that is designed to mine Monero cryptocurrency. Generally, cyber criminals trick people into downloading and installing this program to generate revenue. In summary, the program uses computer resources to mine cryptocurrency when a user logs into the Windows Operating System. Note that the presence of this malware significantly diminishes computer performance.
The cryptocurrency mining process involves solving complicated mathematical problems. To achieve this, the installed cryptominer uses the CPU (Central Processing Unit). People are often unaware that there is a cryptomining process running in the background on their systems. Typically, programs of this type cause high CPU usage, which results in diminished computer performance and increased use of electricity. This can also cause hardware to overheat. Increased use of electricity/higher energy consumption leads to higher electricity bills. Furthermore, users with computers infiltrated by cryptominers receive nothing in return - only the cyber criminals who trick them into installing these programs benefit from the mined cryptocurrency. If a computer is slower, and there is significant CPU usage, this is likely to be caused by an installed cryptominer. Note that conhost.exe (and its associated process ["Console Windows Host"]) is a legitimate windows process, however, cyber criminals disguise a cryptominer behind this name in an attempt to give the impression of legitimacy and to make detection/removal difficult. Fortunately, most anti-virus/anti-spyware suites are capable of detecting and eliminating this malware. Therefore, if you see a Console Windows Host process, which is using many computer resources, immediately scan the system with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

There are many other programs that are designed to mine cryptocurrency including, for example, XMR Miner, BitCoinMiner, and AV64N.exe. They could be used by anyone, however, people also download and install them inadvertently when cyber criminals trick them. It is unknown exactly how they proliferate this particular miner, however, there are a number of commonly-used methods to stealthily proliferate this software.

How to avoid installation of malware?
Do not open attachments (or web links) that are presented in irrelevant emails, especially if they are received from unknown, suspicious addresses. Installed programs/software should be updated using implemented tools or functions that are provided by official software developers. Download software using official and trustworthy websites or other official sources. Avoid third party software downloaders and other sources (mentioned above). Bear in mind that software cracking tools are illegal and are often used to proliferate computer infections. Another way to avoid computer infections is to have trustworthy, reputable anti-spyware/anti-virus software installed and to keep it 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.
