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.

Preparation before removing JS/Redirector.
Before starting the actual removal process, we recommend that you do the following preparation steps.
- Make sure you have these instructions always open and in front of your eyes.
- Do a backup of all of your files, even if they could be damaged. You should back up your data with a cloud backup solution and insure your files against any type of loss, even from the most severe threats.
- Be patient as this could take a while.
- Scan for Malware
- Fix Registries
- Remove Virus Files
Step 1: Scan for JS/Redirector with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by JS/Redirector on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- 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:
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.Step 3: Find virus files created by JS/Redirector on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
