What’s cmd.exe (Windows Command Processor)? Is it safe or a virus?

If you ever use the Windows Command Prompt then you're using cmd.exe (Windows Command Processor). This is a safe .exe you might have noticed in your Windows Task Manager, as long as it's signed by Microsoft.

Windows Command Prompt allows you to execute commands and scripts directly through a textual interface. You can access and control various system functions, such as file management, networking, and troubleshooting, by typing in specific commands. Cmd.exe also provides access to the Windows Management Instrumentation Command-line (WMIC) for system administration and scripting.

If you are a fan of our SpyShelter Antispyware software, you can go to our top right settings, then turn on "command line access" to use all our SpyShelter features directly from the Windows Command Prompt. Neat, isn't it?

As mentioned previously, as long as cmd.exe is signed by Microsoft, and as long as you're the one who executed it, then it should be safe to have on your PC.

However, if you're not sure why it's running then it might be a good idea to do a full Free antivirus scan with Windows Security, or run our SpyShelter Antispyware app and see what exactly launched cmd.exe and when.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
