How to remove the Conteban trojan from your system
Written by Tomas Meskauskas on (updated)
What kind of malware is Conteban?
Conteban is a Trojan, a malicious program also known as Trojan-Win32/Conteban. The exact purpose of this malware is unknown, however, most Trojans operate as 'backdoors'. I.e., cyber criminals use them to gain access to the victim's system and remotely control it.
Programs of this type are often used to infect computers with other malware, for example, ransomware. They can also be used to steal confidential, sensitive information relating to banking, and other personal accounts. Having a computer infected with a Trojan can cause serious problems and, for this reason, Conteban should be removed immediately.
More about Conteban malware
In most cases, cyber criminals proliferate Trojans to generate revenue in various fraudulent ways. Malware of this type often proliferates other malicious software, thereby causing chain infections. If Conteban is one of these Trojans, it might infect the system with high-risk malware such as ransomware.
Ransomware encrypts victims' data and blocks access to it unless ransoms are paid. In most cases, victims cannot access or use their files unless they are decrypted with a specific tool and/or key that can only be provided by the cyber criminals who designed the program.
To obtain the tools, victims are forced to pay ransoms. Note that ransomware is just one example of a program that can be installed on systems through a Trojan. Furthermore, Trojans can be designed to operate as information stealers. In most cases they target sensitive data such as banking information, credentials (logins, passwords) of various accounts, and so on.
Stolen details and accounts could be misused to make fraudulent purchases, transactions, proliferate malware, trick other people into sending money and/or infecting their systems with malware, and so on. These and other actions could be performed by a 'backdoor Trojan', which allows cyber criminals to control the infected system remotely.
They could run/execute various commands, take screenshots, log keystrokes, record clipboard data, restart/shutdown computers, and so on.
As mentioned, it is unknown which type of Trojan Conteban is, however, it must be removed from the infected operating system immediately. Note that some antivirus engines identify harmless files as malicious (these detections are called 'false positives') and there are cases where harmless files might be identified as Conteban.

Similarities with other Trojans
CryptBot, Socelars and CStealer are examples of some other malicious programs categorized as Trojans.
Most programs of this type cause further infections (install other malware), steal sensitive information, and so on. In many cases, people who have computers infected with Trojan-type software become victims of identity theft, experience financial/data loss, problems with browsing safety, privacy, and so on.
How did Conteban infiltrate my computer?
It is also possible to proliferate malicious programs through fake, unofficial software updaters. If used, these install malware rather than updates/fixes, or they exploit bugs/flaws of outdated software installed on the operating system.
Files and software downloaded using Peer-to-Peer networks (torrent clients, eMule), free file hosting websites, freeware download websites, third party downloaders or other similar channels, could lead to installation of malware.
Files or programs that are available for download on these channels might be disguised as legitimate, however, once downloaded and opened, they can infect systems with malicious software. Computer can be infected with malware through software 'cracking', unofficial activation tools.
Typically, people use them to bypass paid activation of licensed software, however, these tools are often designed to download and install malicious programs (including Trojans) instead.
How to avoid installation of malware
Do not to open attachments or web links included in irrelevant emails that are sent unknown/suspicious addresses. Use only official and trustworthy sources to download or install software. None of the sources mentioned above can be trusted. Software should be updated and activated through implemented functions and tools that are provided by the official software developers.
Various unofficial activation ('cracking') tools are illegal and can proliferate and install 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.
