What is [email protected] doing on my computer?

[email protected] is a unique screensaver offered by the SETI program which allows home and office users to contribute to SETI by offering CPU processing time when the computer is idle. This is a non-essential process. Disabling or enabling it is down to user preference.
Non-system processes like [email protected] originate from software you installed on your system. Since most applications store data on your hard disk and in your system's registry, it is likely that your computer has suffered fragmentation and accumulated invalid entries which can affect your PC's performance.

In Windows Task Manager, you can see what CPU, memory, disk and network utilization is causing the SETI@home (win32 client) process. To access the Task Manager, hold down the Ctrl + Shift + Esc keys at the same time. These three buttons are located on the far left of your keyboard.


The [email protected] is an executable file on your computer's hard drive. This file contains machine code. If you start the software SETI@home (win32 client) on your PC, the commands contained in [email protected] will be executed on your PC. For this purpose, the file is loaded into the main memory (RAM) and runs there as a SETI@home (win32 client) process (also called a task).


Is [email protected] harmful?

This process is considered safe. It is unlikely to pose any harm to your system.

[email protected] is a safe process

Can I stop or remove [email protected]?

Many non-system processes that are running can be stopped because they are not involved in running your operating system. [email protected] is used by 'SETI@home (win32 client)'. This is an application created by 'SETI@home'.

If you no longer use SETI@home (win32 client), you can permanently remove this software and thus [email protected] from your PC. To do this, press the Windows key + R at the same time and then type 'appwiz.cpl'. Then find SETI@home (win32 client) in the list of installed programs and uninstall this application.


Is [email protected] CPU intensive?

This process is not considered CPU intensive. However, running too many processes on your system may affect your PC’s performance. To reduce system overload, you can use the Microsoft System Configuration Utility (MSConfig) or the Windows Task Manager to manually find and disable processes that launch upon start-up.

Use the Windows Resource Monitor to find out which processes and applications write/read the most on the hard drive, send the most data to the Internet, or use the most memory. To access the Resource Monitor, press the key combination Windows key + R and then enter 'resmon'.
