File: System.exe

A background system process that runs the Windows kernel, this process is often associated with a variety of viruses and trojans. While necessary to run the Windows User Interface, multiple instances are generally shown in the Windows Task Manager. As a result, malicious programmers routinely name their malware after the process due to the fact that it is not out of the ordinary for many system.exe processes to be running. Recent versions of Windows have renamed the file in order to prevent confusion. If you feel that you are or may be a victim of a system.exe virus, you should scan your system with a reputable antivirus and antimalware tool.http://www.neuber.com/taskmanager/process/system.exe.html 
If you want a detailed security rating about your System.exe (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!

its not a virus, though it could be used as a trojan. It is a network program we use at school to mess with other kids, it allows you to connect to other computers and view what they are doing and even take over their computer. its not exactly 100% dangerous, but if you notice strange mouse movements check your computer for VNC. this program is similar to LogMeIn (www.logmein.com)  See also: Link Tw34k

Windows SYSTEM ffile, not dangerous at all, just search for system.exe if you believe it is a virus. John
I found this file in my Internet Explorer Favourites folder. It was resident in memory, and had another file which it updated (op.sys) with keylogger information, what URL you last visited and what the password was. Stefan
It's loaded event window xp boot in safe mode, lock window registry, user can not open registry,hide taskbar, prevent user install anti-virus application Chinh
keep your "cpu usage" at 100% constantly, even if no programs running. for "j.", "System" is belonged to Windows System, otherwise any files that named "system ..." with exe extension, and running at other than system or well-known user, that must be a malicious programs. so remove it from your computer. emboss

System.exe comes with many installers. Once installs in installs itself onto system volume, then any pendrive you plug in it copys itself to that and the pendrive shows up as a folder. Use Kaspersky to remove it. This is very contageous and it sent over EMAIL and goes from COmputer to computer via USB STICk or FLASH DRIVE/Pendrive. Download Kaspersky to remove it. This is very dangerous and connects to the internet to steal passwords. Bryce

A process simply called System is fine in most cases, but when you see System.exe, it is definitely malware.
I'm thinking that it's Updates exe file, becose i haven't it trough until i installed WinXp and started to update it. Still here are some precents that it is a virus or something like that. DaHous3
We have this file now for two years on our pc, and im thinking it might be a virus. Hope anyone knows if this can POSSIBLY be a windows native process. Kees
I'm thinking that it's Updates exe file, because i haven't it trough until i installed WinXp and started to update it. Still here are some precents that it is a virus or something like that. DaHous3
Its a virus comes from cracked softwares that altered the installer. Minigun
Eats up over 100k of memory when avg is installed. If theres only one system exe on your task manager list and everything is working fine, then it's not a virus. If you want your memory back, uninstall avg. Shana
causes blue screen, allows others acces to your computer, steals all information, searches your ip address and WILL return if not properly blocked. remove it immediatly jake
It looks like this came from something that I've donloaded called "auto_clicker." it came in a zipped file. I'm not totally sure if it is or not though... still running scans to find the stupid virus that this process implies is there. Grant

It could be quite dangerous if its using 100% of memory and/or trying to connect to the internet. Gruntkiller4000
If it is System.exe it is a virus. If it is just System it should be fine
I was downloading ProRAT for pentesting but the official link was down so I got a different one, it basically melted my screen when I ran it and I had to reboot. At first it had the same effect as a batch virus, just flooded my desktop but now all the time I get "system.exe has stopped working," and in my D: drive there is a hidden folder named "downloads" with only one file, system.exe. I can't delete it either, even with force delete from the command line. It hasn't done anything too harmful yet. Alfie
it is system file I got it in my windows8 as normal process Bob
The bot replaces the native windows system.exe file. AVG found it, but couldn't remove it because the original had already been replaced. I completely restored hard drive with image created 2 months earlier using Macrium Reflect. AOK now. BACK UP everything, including the system, folks. This is the only way you really know the virus isn't lurking somewhere... Stephen Smith
System.exe is a trojan. It acts as a server which sends usage information to a remote client and can allow them to take control of your computer. There are no cases where System.exe is a windows process on any version of windows ever. System without the .exe extension (shown in taskmgr) is a windows process, however. Bernard
It's the windows core file that boots on startup. As long as you don't click or install anything that's marked system.exe (that's probably a worm), you don't need to worry about it. Interwebz
