Unix.trojan.coinminerUnix.trojan.coinminer uses victims' computer resources to generate money

The category of Trojans is very versatile – the function of these malicious programs can vary greatly – from encrypting personal files to mining cryptocurrency illegally. Unix.trojan.coinminer belongs to the latter category.

While the functions of this type of malware can vary, it is defined by its distribution method primarily. In other words, users typically install Trojans when they believe that the installer is something else – a pirated program, software crack, or an update. Regardless of this aspect, users who suffer from the infection would put their security and privacy at risk, hence getting rid of it in a timely manner is absolutely necessary.

Unix.trojan.coinminer's main goal is to mine crypto using CPU/GPU/RAM, it could also affect the machine in many other ways. Once on the system, the coin-mining malware imports its own malicious files and takes over the computer – it could grant access to cybercriminals, insert other modules that would steal data or proliferate other malware, and more.

If your anti-malware software has found this virus on your device, you should immediately take action. In this article, we will explain how to deal with the infection correctly and what to do if malware keeps returning after its termination.

Coinminers: still popular and profitable

Cryptocurrency mining has become popular since the first spike in its popularity and high value back in 2018. Users were buying expensive hardware to produce as much crypto as possible, which allowed them to acquire money passively directly from their homes. With the increased popularity, programs like XMRig were created – they helped people easily conduct cryptomining without any issues.

However, cybercriminals had a different idea when it came to these activities. They soon figured out that, by installing certain crypto applications or code into users' devices illegally, they could mine Bitcoin without restrictions and losses. Typically, the miming requires a lot of resources, hence crooks would be saving and receiving money for free.

With the rise of the global coronavirus pandemic, Bitcoin reached the highest value ever,[1] prompting even more mining activities to be undertaken. Since global tech companies are struggling with semiconductor production,[2] cryptomining has become more expensive, which prompted cybercriminals to create more crypto-malware.

Unix.trojan.coinminer removal explained

Crypto-mining is a process when computer hardware, such as the CPU, is used to solve very complicated mathematical problems, producing the currency in the process. This process consumes a lot of electricity in the process and takes a very long time, hence regular users rarely go for it without special equipment.

Crypto-mining malware can solve this problem for cybercriminals easily – they don't have to spend money on resources and instead use those of innocent users. While some older versions of similar malware would use most of the available PC resources for this process, Unix.trojan.coinminer might remain stealthy thanks to implemented caps on CPU usage, which does not lag or interfere with normal computer operation. Likewise, malware imports its own startup items that remain hidden, increasing persistence and stealthiness.

Unix.trojan.coinminer virusDo not ignore the presence of crypto-malware on your system

It goes without saying that the presence of the virus might cause serious issues to the infected users, thus you should not delay its elimination/ The removal of the Unix.trojan.coinminer virus requires your close attention – follow the instructions below to get rid of it for good.

1. Use anti-malware and repair damaged system files

If you already have anti-malware installed on your device and it has detected the virus, quarantine and delete it at once. In some cases, the infection might return – it results in users being spammed with notifications that something was detected again and again. If that is the case, you should proceed with the next step, as the infection might reside within browsers.

However, we recommend trying an alternative security solution, such as SpyHunter 5Combo Cleaner or Malwarebytes, to eliminate all the malicious content from your system. It can automatically find all the virus files and eliminate them at once. Additionally, Unix.trojan.coinminer might be used to insert data-stealing modules or other malicious software installation, so it is important to ensure that all of them are deleted from the system.

The malware drops a multitude of files on the system and changes its settings – these processes can sometimes damage OS files, which might later cause crashes, BSODs, system errors, and much more issues. In order to fix this damage, you don't have to reinstall Windows but instead use ReimageIntego repair and maintenance software which can automatically replace damaged files with brand new ones.

2. Clean browsers

Coinmining malware can often affect web browsers and perform operations through it. Therefore, if caches are not cleaned properly, the activities might continue, even after anti-malware deletes all the other malicious files. You can follow the instructions below.

Avoid malware infections in the future

As we already mentioned, Unix.trojan.coinminer is a Trojan, which means that its point of entry is typically initiated by users themselves. Its classification does not lie within its operation but rather distribution method. The installation of this malware occurs at some point when a malicious executable or script is launched on the machine, all while users believe that it is legitimate. In other words, a Trojan is usually disguised as a file that victims perceive as safe and legitimate. That being said, there could be many ways how the infection can occur.

  • Illegal installers. Users commonly get infected when they misleadingly believe that a software crack or a fake installer is being detected by security software mistakenly, and it is a false positive. However, considering how loose the security measures on these websites are, it makes it a perfect place for cybercriminals to place malware.
  • Fake Updates can be encountered on various websites after being redirected from somewhere. These redirects commonly occur on less secure websites, e.g., torrents, illegal video streaming, and similar. Never download and install anything from pages which claim your system is infected or that you need to update some software (especially Flash Player).
  • Spam emails. Fake phishing emails have been the most successful in infecting users with malware. Thankfully, the amount of malspam sent to users has significantly decreased over the years thanks to sophisticated scanners employed by most advanced tech companies. You should still be aware that emails with attachments, especially those that ask to enable macros, are dangerous and might contain malicious code.

While it is impossible to guarantee total immunity from malware, plenty of things can be done to reduce that probability significantly. Equip your computer with SpyHunter 5Combo Cleaner or another anti-malware and always watch out for malicious websites.

How to prevent from getting trojans

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
