The ctfmon.exe process is a Windows-based process file and runs after using many Microsoft Office products (Word, Excel, PowerPoint, Access, and others). Even after closing or canceling a Microsoft Office application, the process may continue running in the background. In many cases, this is not cause for alarm. However, if it uses an increasingly large amount of system resources, it may be a malicious file.

Should I stop the Ctfmon.exe task or process within the Task Manager?Unless you have experience managing the processes and tasks on your machine, it is best to allow a system scanner or registry scanner to handle those tasks. Many of the tasks are required for performing specific operations on your machine and removing them may cause your program or entire computer to malfunction or reboot.
Should I download a new copy of the Ctfmon.exe file?The only time you should ever download a new version of a system file is when it comes through an application update or from the publisher directly. Be very cautious when downloading system files from third-party websites as they may contain additional software that you would install without knowing. This could cause an even larger issue than the error you are getting from this file!

More information about Ctfmon.exe
In rare instances, this file will use a large portion of system memory. When this happens, the risks of the process or file itself are highly elevated. In normal cases, the process should be using less than 1,000 K of memory. If you view your Task Manager and notice memory usage far beyond that, you either require a system restart to refresh your memory allocation, or your system may be infected with a malicious version of the file.
Malicious infections could impact more than just one file on your system as well. Another file that may be impacted is the hkcmd.exe process. If you experience errors with either of these processes, it is imperative to scan your entire machine to be sure to remove any possible threats from your computer.
