Brocoiner – a Trojan horse which mines cryptocurrency by using the computer's resources

Brocoiner Trojan horse
Brocoiner is a trojan infection which secretly mines cryptocurrency on the infected computer system.

Brocoiner is a trojan infection which secretly uses the PC's resources to mine cryptocurrencies such as Bitcoin, Monero, Ethereum or DarkCoin. All this activity is done without asking for permission and the user usually does not even notice it. Brocoiner virus, also known as Trojan:HTML/Brocoiner, overuses the CPU's and GPU's power which can shorten their “lifetime”. Trojans are very notorious computer viruses which are often affecting numerous victims. Once you detect a Trojan horse[1] on your computer system, make sure you get rid of it as soon as possible. These cyber threats are created to gain income only for themselves and can cause a lot of damage to the computer system which we are going to discuss through out this article.

Name Brocoiner
Also known as Trojan:HTML/Brocoiner
Type Trojan horse
Sub-type Malware
Purpose To mine cryptocurrency on the infected computer system
Symptoms High CPU and GPU usage, slowly running software, computer sluggishness
Possible dangers Might open paths for other malware, can misuse personal information
Removal process Install Reimage to detect the damage

According to cybersecurity experts form Semvirus.pt[2], if your computer system is infected with a virus such as Brocoiner trojan, you might experience these symptoms:

  • CPU and GPU power has been overused recently;
  • Software is launching and running slower than before;
  • Windows struggle when minimizing/maximizing them;
  • You cannot perform computing work normally anymore.

Even though trojans often do not show any signs, they still can be recognized if you are an accurate person. Spotting the signals we have mentioned before, lets us speculate that the PC is infected with a Trojan horse. To figure that out, you can install a reputable anti-malware tool and scan the entire system to detect the virus. If the program finds that the symptoms were not false, remove Brocoiner virus ASAP.

You should carry out the Brocoiner removal as it performs illegal activity. The dangerous cyber threat mines cryptocurrencies without the user's notice to gain benefit for the cybercriminals who hide under this virus. We suggest using only reputable programs to complete the deletion process. Moreover, you can try Reimage which will help you detect all objects that might have been touched by the trojan.

Nevertheless, Trojan:HTML/Brocoiner might include other damaging features such as injecting other malware (e.g. ransomware) or even gathering personal details. If this virus exposes information which is related to your bank account, ID, etc., the data can be misused for illegitimate reasons (e.g. for taking a credit by your name). As you can see, it is very important to avoid Trojan horses and keep your computer safe from possible damage.

Trojan avoiding guide

There are some ways to prevent Trojan horses from entering your computer system. However, first you have to gain knowledge in trojan distribution techniques which are:

  • Spam messages[3] and their attachments. A trojan infection can be hidden in an attached file which you have received from a rogue sender;
  • Malicious websites. Virus-related content might be hidden in hyperlinks which once clicked launch the trojan and it gets secretly installed on the computer.

You can avoid trojans and similar virus by paying more attention to you received emails. If you have got a dubious-looking one which comes from a strange sender or contains lots of grammar mistakes, you should strongly consider eliminating the message permanently. Talking about websites, you should be careful while browsing the web and try not to stay long on pages which look odd to you. If you think you have entered a malicious one – eliminate it the same minute and never return. Additionally, scan your PC with antivirus software in case any hazardous components have slipped through.

Get rid of Brocoiner trojan

Keeping trojans in your system means high CPU[4] usage and crashing programs. To avoid this you should permanently remove Brocoiner virus from your computer system. We recommend using tools such as Reimage, Malwarebytes MalwarebytesCombo Cleaner, Plumbytes Anti-MalwareMalwarebytes Malwarebytes as they will detect all damaged objects that were touched by the virus. Note that the elimination might take a while, so please be patient.

After you perform the Brocoiner removal, make sure you refresh the entire computer system. Keep in mind all the precautionary measures that you have read about avoiding Trojan horses. According to cybersecurity experts from LesVirus.fr, if you know how to stay safe online and always pay attention to your computing work, you will increase your computer's safety level instantly.
