JS/Redirector Trojan – Infection Methods

In order to cause an effective infection, the JS/Redirector malware may infect your computer, using various different types of websites and URLs. The way it is done is that the cyber-criminals compromise various websites that you may visit and embeds JavaScript code in them, resulting in causing the infection by simply visiting those websites. This method of infection is known as file less as there are no files that are dropped on your computer upon infection initiation. All you have to do is visit the suspicious web page.

The other scenario of potential infection is if you have a previous infection with a Trojan horse on your computer, which may come from:

  • Malicious spam attachments sent via e-mail.
  • Messages on the e-mail of the victim, containing malicious web links.
  • Files, pretending to be legitimate software setups.
  • Fake software license activators.
  • Fake key generators.

JS/Redirector Trojan – Malicious Activity

Once an infection with JS/Redirector takes place on your computer, it’s primary goal is to attack your web browser. The JS/Redirector Trojan aims to redirect you to web pages with random domain names and suffixes, reported by Francis Allan Tan Sang to be the following:

mcfnmhumpnf.com
fgytogmtwe.com
chrisbecfiis.com

These are only a small percentage of the web pages to which you may receive browser redirects without your consent. The web browser redirects may also lead you to various other URL’s and some of them may even cause an endless loop of constant redirects. This is often done in order to generate hoax traffic to particular websites. Most cyber-criminals do it in order to boost a rank of a website and then put it up for sale online, claiming it is a successful one or simply to make money by generating visits to a particular URL via pay-per-click schemes.

The worst case scenarios is if JS/Redirector is used in schemes as an intermediary infection file that can infect your computer with other malware, such as:

  • Cryptocurrency miner malware.
  • Other Trojan Horse infections.
  • File-encryption Ransomware.
  • Lockscreen Ransomware.
  • HDD-encryption ransomware.
  • Botnet infections.
  • Worm infection.

Furthermore, since it’s a Trojan Horse, JS/Redirector may begin to perform other activities on your computer system, such as:

  • Collect the keystrokes you type.
  • Obtain your browser history.
  • Obtain your online search history.
  • Steal information directly from your browser, like passwords, etc.
  • Steal financial information.

In addition to this, the malware may also update itself in order to further obfuscate itself and avoid detection on your computer. Whatever the case may be, security experts recommend that you must immediately check your computer for malware after removing JS/Redirector from your PC and change all your passwords as well as enable two-factor-authentication where possible.

How to Remove JS/Redirector Trojan from Your Computer

In order to fully erase this malware from your computer, we strongly advise you to focus on following the steps from the removal manual below. It is divided in manual removal instructions and automatic removal ones. If you have experience in malware removal, you can go ahead and check out the manual removal, but security experts often outline that your best bet is to automatically scan for malicious objects on your computer, associated with JS/Redirector Trojan and secure it completely, using an advanced anti-malware software. This will not only secure your computer and browsers, but will also help you to stay protected against future infections as well.

Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:


1. Hold the Windows Logo Button and "R" on your keyboard. A Pop-up window will appear.

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by JS/Redirector there. This can happen by following the steps underneath:

1. Open the Run Window again, type "regedit" and click OK.


2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.


3. You can remove the value of the virus by right-clicking on it and removing it.
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
