Fuerboos trojanFuerboos trojan is a heuristic detection used by Windows Defender to describe new, yet undiscovered malware samples

Fuerboos trojan is a generic name used by Windows Defender's machine learning technology to describe malware that has not been encountered before. The detection can indicate the infection of ransomware, a backdoor, botnet, banking trojan, or a crypto miner. Depending on the type of infection, these malicious programs might have different goals, including money extortion, sensitive information harvesting, spying, proliferating another malware, etc.

Nevertheless, because Trojan:Win32/Fuerboos is a heuristic detection, it can also indicate a false positive, as it happens with similar detections, such as Win32/Heri, IDP.Generic, and many others. Users said that legitimate tools like ArangoDB[1], WinZip, as well as Blizzard's video game Diablo II.[2]

While it is possible to be a false positive, it is necessary to find out whether or not the detection of Fuerboos trojan poses any threat to your computer first. The best way to do that is by scanning your device with another anti-malware tool and even confirming with the developers of the program in question. Nevertheless, if the infection is real, it is vital to remove Fuerboos virus as soon as possible.

Fuerboos false positive is detected due to the operation patterns of certain applications. For example, many newly-created apps establish a new Windows service that tracks the incoming requests in the combination of the rare binary – the trait of the newest releases.

If Fuerboos trojan infection is not a false positive, however, you might be facing serious consequences, as threat actors might:

  • steal money directly from your bank account by remotely controlling your computer;
  • execute arbitrary code and upload other malware on your device;
  • include you in a botnet operation;
  • lock up your files and demand ransom for the decryption tool;
  • steal your sensitive information and sell it on the Dark Web;
  • secretly mine cryptocurrency by abusing your system resources, increasing electricity bills, slowing down the operation of the PC and deteriorating the hardware, etc.

Unfortunately, but Trojan:Win32/Fuerboos symptoms are not consistent, as it depends on the infection type:[3]

Symptoms of infection vary from threat to threat. In general, threat activity can result in unusual system behaviors, including unexpected opening of windows, unusual network connections identified by your firewall, and decreased system performance.

Fuerboos removal should only be performed if you are sure that the detection is genuine. You can use Windows Defender or other security software to terminate the malicious activity on your machine. Once you delete the virus, you should scan your device with FortectIntego to restore all the affected system files for a swift recovery.

Avoid malware by being attentive online

There are many ways to get infected with malware while browsing the internet. While many methods include users initiating the infection themselves, some, more sophisticated malware distribution methods require no user interaction at all. For example, drive-by downloads, exploit kits, software vulnerabilities, and other techniques can inject malicious code without users initiating it. However, in most cases, infections occur due to negligence from the user part.

To avoid malware infections, follow these tips from security experts:[4]

  • Install reputable anti-malware software with real-time scanning feature;
  • Make sure Windows and the installed apps are patched with the latest security updates;
  • Treat every email with attachments and/or hyperlinks as a potential threat – scan them with tools like Virus Total;
  • Do not download/execute cracks or pirated software;
  • Use ad-blockers on sites that are considered to be high-risk (porn, torrent, gambling, etc.);
  • Enable two-factor authentication for your important accounts and use password managers;
  • Backup your files on an external drive or a virtual storage.

Remove Fuerboos of if it is not a false positive

Before you remove Fuerboos virus from your computer, you need to make sure that it is not a false positive. The easiest way to do so is by downloading and installing alternative anti-malware software, such as SpyHunter 5Combo Cleaner or Malwarebytes. All you have to do is download the security application, install it, and run a full system scan. If any of the AV engines detect the infection as well, it is a high chance that it is not a false positive. If the virus is tampering with the anti-malware application, enter Safe Mode with Networking – we explain how below.

Nevertheless, because heuristic detection deals with brand new and never discovered threats, the best way to find out whether the program in question is malicious is by contacting its developers or flag it up on official anti-virus provider forums.

Once you are sure it is malware, you should proceed with Fuerboos removal as soon as possible to avoid such consequences as identity theft, money loss, or personal data leak.

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.
