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.

Neshta malware

As we mentioned in the introduction, Neshta infects Windows system executable files, it attaches a malicious code to them. Also, it names itself as "", 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.

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 did Neshta infiltrate my computer?

Usually malware is being distributed through spam campaigns, Trojans, unofficial software updating, activation tools and unreliable software download channels. To proliferate malicious programs through spam campaigns, cyber criminals send people emails that contain malicious files/attachments (or web links that lead to them). Typically, these attachments are Microsoft Office documents, archive files (like RAR, ZIP), PDF documents, executable files (like .exe), JavaScript files, etc. If opened, those files install malware. Trojans are malicious programs that, if installed, cause chain infections - most of them are designed to spread other programs of this kind. However, it happens only when people have their computers infected with some Trojan. Fake software updating tools can be used to spread malicious software too. These tools do that by installing malicious programs instead of updates, fixes or by exploiting bugs, flaws of outdated software that is installed on user's operating system. Software 'cracking' tools are programs that supposed to bypass activation of some paid software. However, quite often these tools install malicious programs instead. One more commonly used way to spread malware are various unreliable download sources. For example, free file hosting, freeware download websites, Peer-to-Peer networks (like torrent clients, eMule, and so on), unofficial websites, etc. Typically, cyber criminals upload malicious files and disguise them as legitimate. People who open files downloaded from there often cause installation of some high-risk malware.

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.

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 Spyhunter for Windows.
