What is Brocoiner?

Brocoiner is the malware piece that relies on resources of the affected PC to run crypto

Brocoiner Trojan horseThe trojan infection 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. The 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 FortectIntego to detect the damage

According to cybersecurity experts from[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 the 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 FortectIntego 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.

The infection avoidance tips

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 that 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.

Remove the Brocoiner trojan and stop the unwanted behavior or even malicious processes

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 FortectIntego, SpyHunter 5Combo Cleaner, 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, 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.

How to prevent from getting trojans

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
