After when I downloaded a program, I found random adverts popping up and when I scan with MalwareBytes, I found system.exe to be a trojan.agent.stm
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.
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...

it is system file I got it in my windows8 as normal process
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.
If it is System.exe it is a virus. If it is just System it should be fine
It could be quite dangerous if its using 100% of memory and/or trying to connect to the internet.

Best practices for resolving system issues

A clean and tidy computer is the key requirement for avoiding problems with system. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the system.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
