FireHooker is a brand new Trojan-based infection that sneaks inside unprotected computers and exploits their vulnerabilities and resources. According to security researchers, FireHooker may be listed as a Trojan Horse and should be removed from the system.


The FireHooker Trojan can stealthily infiltrate your sysytem.

The Trojan Horse viruses are definitely one of the most popular and troublesome group of malware. What you particularly need to know about them, and specifically about new threats like FireHooker is that they are likely to be very advanced and very harmful.

In the following lines, you can read what you might expect of a virus like FireHooker, and, in the case that you have already been infected with a Trojan named this way, you will also get a comprehensive manual that will guide you through the steps of full and successful removal of FireHooker from your computer.

However, before you move to the guide, we suggest that you take a few more minutes to read the rest of the article in order to understand more about the basic features of the virus. Not only can this allow you to remove it but also learn how to protect your computer from similar pieces of malware in the future.


Viruses such as TR/AD.FireHooker.BU are very persistent and also have the potential to sneak inside the system without any evidence or red flags that can raise suspicious. Once inside the targeted computer, TR/AD.FireHooker.BU may obtain administrative rights and conduct all sorts of insidious malicious deeds without the victims having any clue what is going on in the background of their OS.

Unfortunately, in certain situations, the Trojan has already completed its malicious agenda by the time the victim realizes there has been an infection and nothing could be done to undo what the malware has done. That’s why it is so important to have a reliable antivirus program in place in order to be able to identify threats like FireHooker quickly and protect your computer from potentially irreparable harm.

And since we mentioned protection, we also would like to stress on the importance of having good online habits. If you apply few simple online safety rules, you will greatly reduce the chances of meeting Trojans, Ransomware, Spyware and other nasty viruses across the web. For instance, you should try to keep away from spam e-mail messages, sketchy web links, random pop-ups, and different web attachments, pirated copies of software and low-quality websites since these are the ideal transmitters of various security hazards.

Things could quickly get really bad if you accidentally land on FireHooker or some similar malware while you surf the web carelessly because, most Trojans could harm the computer they  get to compromise in a number of ways. Hackers may code them and re-program them to perform multiple malicious tasks one after the other. A Trojan can spy on its victims, or infect the compromised computer with other viruses. The notorious ransomware viruses are sometimes inserted onto users’ machines with the aid of a Trojan.

The conclusion that can be drawn from this paragraph is that Trojans are usually incredibly harmful and must be removed from the compromised machines ASAP. If not, a number of problems may occur as a consequence of their malicious background activities.
