Are you experiencing issues related to a Windows process called Werfault.exe? The very first thing to mention is that, by design, Werfault.exe is not a malicious process. In fact, it is a legitimate Windows 10 / Windows 11 process used for sending error reports to Microsoft. Thanks to Werfault.exe and Windows Error Reporting, Microsoft developers can fix Windows app-related issues users experience. However, trojans and cryptocurrency miners are known to take advantage of legitimate Windows processes in order to use the compromised machine’s CPU resources, steal information from it or install a backdoor for further malware distribution. If you believe that the nature of the Werfault.exe process is compromised, it is advisable to check your system for malware.
How to check whether Werfault.exe is safe or not?
One way to perform such a check is by verifying the publisher of the file. You can do that by right-clicking the file and checking its properties for a legitimate publisher (in this case, Microsoft). If the file is signed by Microsoft, then it is most likely safe to use and you can leave the process running. However, if Werfault.exe is not signed, then you should be alarmed that your system could be compromised. In any case, if you find yourself reading this article, then it is safe to assume that you have your doubts concerning Werfault.exe’s safety and origin. The best thing to do is making sure your Windows system is malware-free.
N.B. The article below will help you only in case Werfault.exe is a malicious process.

Werfault.exe – Overview
A malicious Werfault.exe variant 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, Werfault.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.
In most cases of trojan infections, the main goal 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 Werfault.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.
