Dllhost.exe file is an important Windows operating system file, which is also known as COM Surrogate. This process is responsible for showing thumbnails, helping File Explorer to function, and so on. If you open the Task Manager, you always see this process running in the background. Generally speaking, all executable (.exe) files are necessary for each software application because they include instructions how the computer has to carry out particular functions. When you click on this file, the computer reads the command created by the software developers and runs it. Without this kind of files computers and applications won’t work. However, seeing Dllhost.exe Application Error when launching computer or running some programs is a sign that something is wrong with your computer. Uninstalled Windows updates may cause this error, as well as invalid registry entries, damaged, corrupted or deleted Dllhost.exe files or other files related to it. However, often this error is caused because by the malware attack.

Malware and viruses can use the name of Dllhost.exe to bypass computer’s security and infiltrate the system. Often malware is spread in the insidious .exe file via malicious SPAM emails, infected websites or malware-laden ads. Therefore, after getting inside the computer, malware can corrupt, replace or damage .exe files and Dllhost.exe might be one of them. Hence, you receive either Dllhost.exe Application error or one of these warnings:

  • “Dllhost.exe Application Error.”
  • “Cannot find dllhost.exe.”
  • “Dllhost.exe not found.”
  • “Dllhost.exe is not a valid Win32 application.”
  • “Dllhost.exe has encountered a problem and needs to close. We are sorry for the inconvenience.”
  • “Dllhost.exe failed.”
  • “Dllhost.exe is not running.”
  • “Faulting Application Path: dllhost.exe.”
  • “Error starting program: dllhost.exe.”

For this reason, you have to scan your computer with strong and reputable malware removal tools and make sure that your computer is not infected. We recommend performing full system scan with Reimage.
