Neshta virus removal guide
What is Neshta?
Neshta is a malicious software that is designed to infect executable (.exe) system files and use them to collect system information. It might target removable storage devices and network shares too. Neshta sends collected information to a web server that is controlled by cyber criminals. Research shows that this malware was mainly used to attack companies that specialize in finances, consumer goods, energy. Also, it was used to attack manufacturing industry. Either way, Neshta should be removed from the operating systems as soon as possible.
As we mentioned in the introduction, Neshta infects Windows system executable files, it attaches a malicious code to them. Also, it names itself as "svchost.com", Neshta's victims can find this process running in Task Manager and its executable file in "C:\Windows\". This malware modifies Windows registry so this process would start running every time an infected executable (.exe) file is launched. In other words, Neshta creates a persistence mechanism. It is worth mentioning that it does not target .exe files that contain "%SystemRoot%", "%Temp%" or "\PROGRA~1\" in their path. Additionally, this malware drops two other files, "directx.sys" and "tmp5023.tmp", it puts the first one in "%SystemRoot%\" and the second one in "%Temp%\" directories. The "directx.sys" file is a text file which contains the path of the last infected file to launch. This text file gets updated each time an infected file is launched. Neshta uses infected files to collect various system information related to the operating system, hardware and installed software. Collected data is then sent to a remote server and crooks can easily use it to generate revenue in malicious ways, thereby causing a variety of privacy issues.

To eliminate Neshta virus our malware researchers recommend scanning your computer with Spyhunter.
Cyber criminals distribute this malware through other malware or infected files that people download from unreliable download sources. Examples of malicious programs that are designed to spread other software of this kind are Tortoiseshell, Torpig and Nymeria. Typically, people who have their computers infected with such programs are unaware of that.

How to avoid installation of malware?
It is not safe to open attachments or web links that are presented in various irrelevant emails, especially if they are sent from unknown, suspicious addresses. Such emails (and files in them) should not be trusted/opened. Furthermore, we advise to download all software using direct downloads links and trustworthy, official websites. All other tools (examples are mentioned in the paragraph above) should not be trusted. Also, it is important to update installed software (and operating system) using tools or implemented functions that are designed by official software developers. Other tools should not be used. The same applies to third party activation ('cracking') tools - it is not legal to use them and quite often they infect computers with malware. We also recommend to have a reputable antivirus or anti-spyware software installed and scan a computer with it regularly. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
Neshta edits Windows registry (edits "HKLM\SOFTWARE\Classes\exefile\shell\open\command" key by setting the value to "%SystemRoot%\svchost.com "%1" %*"):

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 Spyhunter for Windows.
