What is TR/AD.FireHooker.BU?

TR/AD.FireHooker.BU – Avira detection name for a potentially malicious program

TR/AD.FireHooker.BUTR/AD.FireHooker.BU is a detection name of a malicious adware program

TR/AD.FireHooker.BU is the name of an unidentified adware infection that might reside in various places on a Windows system, as well as the web browser. Users reported that they began seeing pop-up messages from Avira security software, which attempted to warn about a threat. In most cases, the security program flags that a suspicious executable, such as 105c6c37-ee2a-2a76-e42c-02506c4d1be0.exe, was detected inside a Windows temp folder.

While under normal circumstances, TR/AD.FireHooker.BU virus would be deleted straight away, users reported that it keeps coming back as soon as they reboot their computers. Other security applications detect the infection as FileRepMalware, W32.Adware.Gen, Riskware/WebCompanion, and others. If you want to find out how dangerous the malware is and how to delete TR/AD.FireHooker.BU for good, keep on reading.

Type Adware, Trojan

Therefore, the infected users should clean their browsers adequately, as explained below, and then scan the device with an alternative anti-malware
Further steps Malware or adware infections can diminish the performance of your computer or cause serious stability issues. Use FortectIntego to remediate your device and ensure that the virus damage is fixed

TR/AD.FireHooker.BU is a relatively generic detection name for a Trojan – a type of computer infection that gets installed on the system by pretending to be something else. Since Trojan's functionality is not defined by its category, it can represent various threats, such as ransomware, viruses, worms, RATs, adware, and much more. This particular threat has been linked to intrusive adware specializing in browser hijacking and delivery of intrusive advertisement campaigns.

Those who do not remove TR/AD.FireHooker.BU malware might suffer from various annoying and even dangerous consequences. Adware's main goal is to hijack users' traffic and deliver intrusive pop-ups, deals, offers, coupons, and other advertisements regardless of which websites are visited. While these ads can be stopped with an effective ad-blocker, the root cause of the infection should be found and eliminated.

Typically, the suspected malicious file can be spotted in the Windows temp folder (C:\Windows\temp). Users reported that once the malicious file is deleted, it always comes back. Since the location is a temp folder, there is a chance that the infection is recurring due to an online component. For example, Google account sync might store some cached[1] files on its database, resulting in repeated infection.

Since TR/AD.FireHooker.BU removal is not successful with Avira, security experts[2] recommend scanning the device with alternative anti-malware, such as SpyHunter 5Combo Cleaner or Malwarebytes. Since having two security applications simultaneously is not recommended, you should delete all the anti-malware tools first before performing a scan with a different AV.

If that is not successful and the TR/AD.FireHooker.BU virus keeps returning, you need to clean your web browser, as the infection can exist there. Below you will find the instructions on how to delete extensions and clear browsing data. If that also does not work, you should reset your web browser entirely.

As a final step, you should also run a scan with FortectIntego repair software – this application would ensure that all Windows components are repaired after a malware infection, and the machine is not crashing, returning errors, or suffering from other stability issues.

Trojans can be extremely dangerous: avoid them at all costs

As mentioned above, Trojans are defined by the way they are distributed. Typically, users open an executable or another file believing that it is harmless. Quite often, such files are distributed on fake software websites that imitate the original ones. Since the one of the TR/AD.FireHooker.BU samples was found on a fake Audacity audio app website, many German users infected with this malware, believing that the it is legitimate program installer. Thus, it is important to always check the URL of the address you are downloading software from (ensuring the connection is protected by SSL is also important, although it does not guarantee anything).

Other ways users manage to download Trojans is when they download programs from suspicious third-party websites, such as torrents. Security researchers recommend staying away from pirated software and cracks, as these files are often boobytrapped with malware.

Finally, fake updates, typically those of Flash Player, are also commonly used by cybercriminals to make users install malicious software on their system. Keep in mind that Flash is an outdated multimedia plugin that is no longer required and will be discontinued by the end of 2020.[3]

Delete TR/AD.FireHooker.BU from your system

As evident, you should not ignore any pop-ups and warnings from your security software. While there is a small chance that the detection is a false positive, and there is no need for TR/AD.FireHooker.BU removal. To be sure, you should uninstall your current security software and perform a full system scan with an alternative tool, such as SpyHunter 5Combo Cleaner or Malwarebytes. To fix Windows problems that could arise after the infection, we recommend using FortectIntego.

How to prevent from getting adware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
