Fileless Malware Trojan Removal

This page will help you with the removal of Fileless Malware. The Fileless Malware is a new breed of a Trojan horse computer virus.

In the article below you will find all the information about the infection with Fileless Malware (a version of a Trojan horse), as well as some details about this virus’ characteristic features. We are also going to suggest a way to remove such a contamination. 

Trojans: not myths, but real cyber nightmares

These cyber threats have been named after the mythological Trojan horse that won the victory for Greece in the Trojan war. However, they are truly dangerous, not just subjects of stories. If you are wondering why these viruses have received that common name, the reason is that they act just like the horse from the myth – they use a weakness in your system to get inside. Once there they wait until the circumstances are perfect and they attack what they have been programmed to attack on your PC. Then you end up infected and probably experiencing terrible consequences and you have no idea how that contamination had occurred. Trojans are probably the favorite tools of hackers all around the world, because they can be used for a variety of different purposes and with many various intentions. These viruses are really capable of performing anything once incorporated into your computer. That is why we are describing them in general here, not just Fileless in particular. They could indeed be responsible for the following negative consequences and many more:

  • An infection with a Trojan might cause corruption or destruction of files. This kind of malware is often exploited by hackers just to have fun. What we mean by this statement is that cyber criminals are delighted when they delete files, corrupt data or destroy an entire system. For that purpose, they most usually use Trojans. This is kind of like a hobby for them. That’s why you shouldn’t be surprised if as a result of the infection with Fileless, some of your files are lost or your whole OS gets destroyed.
  • Your PC might be turned into a bot and its resources might get exploited. One of the most likely usages of Trojans is for draining your computer resources for the purpose of distributing spam or mining cryptocurrencies. This means that your computer could be used as a bot as a result of the contamination with a Trojan.
  • The hackers might be after your identity or your money. Sometimes cyber criminals exploit Trojans with the desire to steal some money from innocent users. The virus is perfectly capable of remembering your key strokes, bank account credentials and other personal information that could later help the hackers drain your accounts and steal all your funds. Also, your identity might be in danger because the hackers harassing you might alter all the information about you online and might even commit some crimes on your behalf, which is more than scary.
  • The hackers may just want to spy on you. Some cyber criminals show signs of physically abusive or stalking-oriented behavior. They might spy on you using such a virus to control your machine remotely, turn on your microphone or camera and watch you 24/7. What’s really bothering is that such criminals might later become physical ones. And to top it all off, they will have all your private details such as address, occupation, appearance, etc.
  • The virus might be looking for classified information from the company you work for. Sometimes the criminals behind the virus are really interested in finding out some company’s classified data and they might use an employee’s PC to hack the professional network. They may have nothing to do with you personally.

Where can Fileless be found?

Fileless, just like most of the other Trojans, can most often be found together with a Ransomware variant as a component of a spam email or attachment (image, archive, .exe file) or as a drive-by download from following a malicious pop-up ad. Of course, there could be other various sources of these viruses like shareware, bundles, torrents and webpages, infected with them. It is very important that you stay as far away as possible from Fileless’s potential sources mentioned above. What else you need to do is to install the most powerful anti-malware tool available. Purchasing a top-quality anti-virus program will help you a lot against all kinds of threats. Just keep it up-to-date and use it regularly for scanning for malware. As for removing Fileless, we suggest that you implement all the instructions in our Removal Guide. Hopefully, you will get the chance to solve your issue and save your system from further damage.
