Fluorosulfonic.exe – Overview

Fluorosulfonic.exe can invade Windows operating systems in a stealthy manner, via fake applications and infected sites. This type of malware can seriously damage an infected computer, as it may steal sensitive information and open a backdoor to more threats.

Other distribution tactics that the malware operators may use include fake software updates, malicious spam emails, and trojanized applications.

Shortly said, Fluorosulfonic.exe’s access to a computer enables it to create several malicious files that may compromise both the system and the network. Since such malware usually wants to remain undetected, you may spot it after it has successfully corrupted your operating system. One way to catch this threat is to notice that some of your installed programs do not run correctly.

The trojan may also aid the installation of additional malware on the system as it could open a backdoor. Since the added malware can be of any kind, your device may be hit by ransomware, spyware, another Trojan, adware, etc.

However, the main goal of the malware at the moment is data theft. Hackers can steal sensitive login credentials for various accounts, perform fraudulent transactions, get access to your email accounts to send spam, and many more. We recommend using an advanced security tool for its complete removal. Otherwise, some elements installed by the infostealer may remain on your computer, leaving it vulnerable to future infections.

In a nutshell, these are the most common methods used by cybercriminals to spread trojans such as Fluorosulfonic.exe:

  • Exploit kits;
  • Phishing emails;
  • Bundled freeware installers;
  • Fake updates and infected pages.

Due to its malicious nature that endangers your various accounts, we advise you to scan your system to make sure that it is safe.
