→Windows 2000, Windows 7, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows Server 2008, Windows Vista, Windows XP
JS.Fakeransom and JS Trojans Technical Description
Our team has already analyzed one ransomware that uses JavaScript to prevent the user from closing the page – the so-called MoneyPak Virus. The phishing site that initiated the attack presented a JavaScript loop that was set to lock the browser to the page.
For instance, when trying to visit a particular page after the suspicious site has been loaded, a warning is likely to show up. Such warning messages typically act as scareware and aim at frightening you. Such a message may contain information about an illegal action that you have recently performed online (such as visiting adult content pages), or installing pirated software. Interestingly enough, porn websites and pirated software are typically at fault for ‘infections’ of that type.
Using compromised websites to spread malicious code is neither new nor innovative. But it is definitely an effective technique in the realm of malware distribution.
JS.Fakeransom and similar threats may attempt to redirect the browser to another page. Some JS Trojans may employ websites compromised via SQL injection attacks or by using Blackhat SEO. Another way for such a threat to ‘infect’ the browser is if the page containing the malicious script is stored in the browser’s cache.
JS.Fakeransom Removal Methods
Pay attention to the following tips to improve your PC’s security:
- Make sure to use additional firewall protection. Downloading a second firewall (like ZoneAlarm, for example) is an excellent solution for any potential intrusions.
- Make sure that your programs have less administrative power over what they read and write on your computer. Make them prompt you admin access before starting.
- Use stronger passwords. Stronger passwords (preferably ones that are not words) are harder to crack by several methods, including brute forcing since it includes pass lists with relevant words.
- Turn off AutoPlay. This protects your computer from malicious executable files on USB sticks or other external memory carriers that are immediately inserted into it.
- Disable File Sharing – it is recommended if you need file sharing between your computer to password protect it to restrict the threat only to yourself if infected.
- Switch off any remote services – this can be devastating for business networks since it can cause a lot of damage on a massive scale.
- Make sure always to update the critical security patches for your software and OS.
- Employ a virus-scanning extension in your browser that will scan all the downloaded files on your computer.
- Turn off any non-needed wireless services, like Infrared ports or Bluetooth – hackers love to use them to exploit devices. In case you use Bluetooth, make sure that you monitor all of the unauthorized devices that prompt you to pair with them and decline and investigate any suspicious ones.
- Employ a powerful anti-malware solution to protect yourself from any future threats automatically.

Step 2: Uninstall JS.Fakeransom and related malware from Windows
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:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by JS.Fakeransom 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.Fakeransom 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.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove JS.Fakeransom
Step 5: Try to Restore Files Encrypted by JS.Fakeransom.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and JS.Fakeransom aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
