How to remove SystemBC malware from the operating system
Written by Tomas Meskauskas on (updated)
What kind of malware is SystemBC?
SystemBC is malicious software written in the C++ programming language. It sets up SOCKS5 proxies on computers so that cyber criminals can hide malicious traffic that is associated with other malicious programs.
In summary, cyber criminals proliferate SystemBC together with other malware and use the aforementioned SOCKS5 proxies to prevent other malware from being detected. SystemBC is used by a number of cyber criminals and can be purchased on hacker forums. To avoid possible damage, you are strongly advised to remove SystemBC from your system immediately.
More about SystemBC malware
Cyber criminals use SystemBC as a tool to prevent other malware (such as DanaBot, Amadey, and others) from detection by anti-virus software that is installed on the victim's computer.
As mentioned, to hide traffic and avoid detection, SystemBC creates a SOCKS5 proxy, which acts as a channel between the victim's computer and Command and Control (C&C) server controlled by cyber criminals.
In summary, created proxies allow cyber criminals to evade a direct connection between an infected computer and C&C server, and thus maintain undetectable malicious traffic. Software such as DanaBot and Amadey steals personal details (passwords, logins, and other credentials), logs keystrokes, causes installation of malicious software, and so on.
The installed malware can be used to steal details that could be used compromise various accounts, make fraudulent purchases and transactions, trick other people into sending money to cyber criminals, install high-risk malware including ransomware, and perform other actions that enable cyber criminals to generate revenue.
These infections communicate with C&C servers to receive commands and to send recorded data. Thus, hiding the traffic is important to cyber criminals.
In summary, SystemBC is essentially used to prevent other malware infections from being detected. The presence of these malicious applications can cause serious problems such as data/financial loss, privacy issues, and a number of other serious issues. To avoid this, remove SystemBC from the operating system immediately.

SystemBC malware in general
SystemBC acts as a conduit between victims and cyber criminals. It does not proliferate malware, but does hide malicious traffic. Therefore, SystemBC is a dangerous threat. Typically, people do not and install software such as SystemBC intentionally. Information about how cyber criminals proliferate this malicious software is provided below.
How did SystemBC infiltrate my computer?
Research shows that SystemBC infects systems through malware such as DanaBot, Amadey, and other software of this type that is already installed on the operating system, or through RIG and Fallout exploit kits. Exploit kits are programs that are used to initiate exploits against installed vulnerable software.
Typically, this happens when software is outdated, contains bugs/flaws, etc. To trick people into installing malware that can be used to proliferate tools such as SystemBC, cyber criminals employ spam campaigns, Trojans, dubious software download channels, fake updating and activation tools.
Spam campaigns cause computer infections through files that are attached to emails. These attachments are usually Microsoft Office of PDF documents, archive files such as ZIP, RAR, executable files such as .exe, JavaScript files, and so on. Once opened, they install various high-risk computer infections.
Trojans are malicious programs that proliferate other malware. When installed, they cause chain infections. Examples of dubious software download channels are Peer-to-peer networks (eMule, torrent clients, and so on), third party downloaders, freeware of free file hosting websites, etc.
They are used to disguise malicious files as legitimate. If downloaded and opened, however, they infect computers with malicious software. Fake/unofficial software updating tools exploit bugs/flaws of outdated software that is installed on the computer, or they download and install malware rather than updates.
Unofficial activation ('cracking') tools supposedly activate paid software free of charge, however, these programs often install malware and do not bypass any software activation.
How to avoid installation of malware
Do not open attachments or web links that are present in emails received from unknown or/and suspicious addresses. If an attachment or website link within an email is irrelevant, do not open it. Update software through implemented functions or tools that are provided by official developers.
Do not download software from untrustworthy/unofficial websites or using any other tools. The safest way is to use official, trustworthy websites and direct links. Unofficial software activation tools should not be used, since this is illegal and often leads to installation of malware.
Have reputable anti-spyware or anti-virus software installed and scan operating system with it regularly. These tools detect and remove threats before they can do any harm. 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.

How to remove malware manually?
Manual malware removal is a complicated task - it is usually best to allow antivirus or anti-malware programs to do this automatically.
To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button.
Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

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 Combo Cleaner Antivirus for Windows.
