Remove Fluorosulfonic.exe Virus

If you have a Windows virus, continue with the guide below.

If you have a Mac virus, please use our How to remove Ads on Mac guide.

The first thing that we suggest you do if you want to quickly remove Fluorosulfonic.exe from your computer is to try the following:

  1. From the Start menu of your computer, open the Control Panel.
  2. In the Control Panel, navigate to Programs and Features and select Uninstall a Program.
  3. You should see a list of all the programs that are installed on your system. Carefully search for Fluorosulfonic.exe and other questionable-looking programs that you can’t remember installing, are outdated, or you rarely use.
  4. Uninstall Fluorosulfonic.exe and anything else that looks suspicious. If a warning message like the one below appears on your screen when you click Uninstall, select NO and complete the uninstallation process:

After you do that, the major portion of the threat should be gone. However, please note that Fluorosulfonic.exe might have placed other malicious components in different locations of your system. Therefore, it is a good idea to follow the detailed steps below and delete all traces of the Trojan from your PC.


During the steps that you are about to complete below, you will need to restart the computer. For this reason, we recommend you to click the bookmark icon in your browser and save the link to this Fluorosulfonic.exe removal guide, so you can easily load it and continue from where you left. Or, for your convenience, you can open the guide on another device and follow the steps from there.

Also, before you proceed to the instructions that follow, we recommend you to reboot the compromised computer in Safe Mode. This will eventually make it easier to spot Fluorosulfonic.exe and its malicious processes and remove them.



In Windows, the Task Manager is the place where you get to see all processes that are presently running on the computer. That’s why, in this step, you need to use the CTRL + SHIFT + ESC key combination and start the Manager. Then, click on the Processes tab and carefully look at each process listed there in a search for something suspicious.

In many cases, the malicious processes related to Fluorosulfonic.exe may not have the same name. Therefore, you should look for signs of maliciousness, such as strange characters and misplaced letters in the name of a seemingly legitimate process. Also, you have to pay attention to the CPU and Memory consumption because, sometimes, a sign of a malicious activity is the usage of a lot of system resources without any actual activity from your side.

A quick way to check if a suspicious process is dangerous is to select it, right-click on it and then select the Open File Location option from the pop-up menu that appears on the screen:


You will see the files, related to that process, in a folder. To check them for malware, simply use the drag and drop function and scan them with the free online virus scanner available below:Shortcode

A danger even in one of the scanned files should be enough for you to end the entire process. You can do that by going back to Task Manager>>>Processes, select the questionable process, right-click on it and choose the End Process option. Once you do that, you should also delete its related files from their File Location folder.

Note: If you find more than one suspicious-looking process in your Task Manager, please use the scanner above to check everything. Make sure that before you move to the next step, you have only legitimate processes running on your computer.


In case your computer is compromised with Fluorosulfonic.exe, another very important thing that you should do is to check what programs and processes are set to start with the start of your system. Sometimes, Trojan threats tend to add malicious startup items to the computer that start operating as soon as the user switches it on.

To do that, click on the Start menu button and type msconfig in the search field. Then, press enter, and you should see the following window:


From the tabs that are available, click on Startup and search for Startup items that look suspicious, have “Unknown” Manufacturer or an odd name. If you believe that something from the list could be related to Fluorosulfonic.exe, uncheck its checkmark and click OK to save your changes.


In case you have a suspicious that another big threat, (like ransomware) is operating on your PC, or the system is hacked, make sure that you check the Hosts file of your computer for changes.

To open the Hosts file, copy the following:

notepad %windir%/system32/Drivers/etc/hosts

Then, paste it in the Start menu search bar and press Enter.

If you are hacked, you may see malicious IP addresses under the Localhost section of the text, just like on the image below: 

hosts_opt (1)

The last system location where you need to seek Trojan-related traces is the registry. Threats like Fluorosulfonic.exe may add some helper components and files there in order to gain persistence and remain on the computer for as long as possible. Therefore, you need to carefully search the registry for any malicious files related to the threat and delete them without deleting anything else.

Typically, this is a task for professionals because regular users may easily mistake the legitimate files of their system for malware and delete them, in this way causing more harm than good.

If you know what you are doing and want to use the manual removal method instead of using a professional removal tool to deal with Fluorosulfonic.exe, here is what needs to be done:

  • Start the Registry Editor by typing Regedit in the search field of the Start menu.
  • Then, press Enter.
  • When the Registry Editor opens, press CTRL and F from the keyboard in a combination.
  • Write the name of the Trojan in the Find box and click Find Next.
  • Delete any entries that are found by right-clicking on them.

In case that the Find function cannot find anything mathing the Trojan’s name in the registry, manually navigate to each of these directories by using the left panel of the Editor:

  • HKEY_CURRENT_USER—-Software—–Random Directory. 
  • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
  • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Carefully search for randomly named files and folders that have been added recently and if you believe they are part of the infection, delete them.

If nothing helps, and Fluorosulfonic.exe cannot be removed manually no matter how carefully you repeat the steps from this guide, you should better download the anti-virus program we recommend and run a full scan of your system. Sometimes, sophisticated threats like this one tend to use a combination of tricks to remain on the computer and their removal without the help of a professional antimalware software may not be successful.
