What is ServHelper?
ServHelper is a malicious backdoor program. Malware of this type is designed to open a "backdoor" for other malicious software. These programs can be used to infect systems with trojans, ransomware, cryptocurrency miners, and other malware. Therefore, the threats posed by ServHelper and programs akin to it - are extensive.
ServHelper malware overview
There are two variants of ServHelper. One is designed to cause chain infections, while the other has remote control features. The latter is capable of establishing remote desktop access, which can be used to control user accounts and browser profiles.
To elaborate on ServHelper's abilities of downloading/installing additional malware - such functions can be employed to infect devices with all sorts of malicious programs.
The term "trojan" encompasses programs with a wide variety of harmful functionalities, e.g., enabling remote access and control over machines (RATs - Remote Access Trojans); downloading files; extracting data from the system, installed browsers, and applications; spying - recording keystrokes, and audio/video via microphones and cameras, taking screenshots; and so on.
Ransomware is designed to encrypt data and/or lock the device's screen to demand ransoms for the decryption/ access recovery. Cryptominers abuse system resources (potentially to the point of complete system failure or permanent hardware damage) - to mine cryptocurrency.
To summarize, ServHelper may cause multiple system infections, hardware damage, permanent data loss, severe privacy issues, financial losses, and identity theft.

Backdoor malware examples
MosaicLoader, RustyBuer, Ostap, and Spectre are a few examples of malicious programs with backdoor functionalities. However, malware often has additional functionalities. Regardless of how this software operates, it endangers device and user safety. Therefore, it is crucial to use anti-virus software and immediately eliminate all detected threats.
How did ServHelper infiltrate my computer?
ServHelper has been observed being actively distributed via websites that promote illegal activation tools ("cracks"). "Cracking" tools can cause infections instead of activating licensed software.
In fact, malware is commonly spread through dubious download sources, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party downloaders. Fraudulent updates are used in distribution as well. These updaters infect systems by exploiting outdated program flaws and/or by installing malicious software.
How to avoid installation of malware?
Suspicious and irrelevant emails should not be opened, especially any attachments or links found in them - as they are sources of potential infections. It is recommended to only use official and verified download channels. Furthermore, all programs must be activated and updated with tools provided by legitimate developers.
It is crucial to have a reputable anti-virus installed and kept up-to-date. This software has to be used to perform regular system scans and to remove detected threats. 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.
