Fuerboos Trojan

What is Trojan:Win32/Fuerboos?

Trojan:Win32/Fuerboos is the name of a threat detected by Windows Defender. Although the message states that Trojan:Win32/Fuerboos is presented as high-risk threat, this is often a "false positive". Therefore, the anti-virus suite detects a legitimate file as malicious and eliminates it.

These so-called "false positives" typically occur due to false entries in malware databases that contain misleading information. Therefore, anti-virus suites end up treating legitimate files as malicious. In this case, the false positive is detected by Windows Defender's artificial intelligence.

False positive detection may seem insignificant, however, detected data is removed (anti-virus suites permanently delete files). Therefore, false positives can lead to loss of important data. Fortunately, anti-virus developers update databases frequently and false positives typically do not last long.

If you encounter notifications about this threat, immediately update your anti-virus suite. In some cases, databases contain slightly misleading entries. For example, the list of malware files includes legitimate entries, thus resulting in false positive detection.

So, there is a small chance that the Trojan:Win32/Fuerboos virus is included. If you are notified of its presence, scan the system with several anti-virus suites to be sure. Remember, however, that only one anti-virus suite should be installed at once. These programs can interfere, resulting in inaccurate scan results.

There are many false positives similar to Trojan:Win32/Fuerboos. For example, Trojan.gen.npe.2, ERDNT.LOC, Trojan:O97M/DPLink.A, and many others.

In any case, the result is identical - deletion of useful data.

How did Trojan:Win32/Fuerboos infiltrate my computer?

There are hundreds of malware distribution methods, but the most popular five are: 1) chain infections [one virus proliferates another]; 2) spam email campaigns; 3) fake software updaters; 4) peer-to-peer [P2P] networks, and; 5) third party software download sources.

Spam campaigns proliferate malicious attachments [usually Microsoft Office documents] that, once opened, download and install malware. Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than promised updates.

P2P networks (torrents, eMule, etc.) and other unofficial download sources (free file hosting websites, freeware download websites, etc.) present malicious executables as legitimate software, thereby tricking users into downloading and installing viruses.

How to avoid installation of malware?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Carefully analyze each email attachment received.

If you believe that the file is irrelevant or has been sent by a suspicious/unrecognizable email address, do not open it. We advise you to download your programs from official sources only, using direct download links. Third party downloaders/installers often include rogue applications, and thus these tools should never be used.

Furthermore, keep installed applications up-to-date. To achieve this, however, use implemented features or tools provided by the official developers.

Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware .

If you checked the list of programs running on your computer, for example using task manager, and identified a program that looks suspicious, you should continue with these steps:

 Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

Restart your computer into Safe Mode:

Extract the downloaded archive and run the Autoruns.exe file.

In the Autoruns application, click "Options" at the top and uncheck the "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 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, 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.
