When s24evmon runs, cmd.exe runs ipconfig.exe (every few seconds)

Well!It is part of interl wifi binary files! I bblocked it by firewall and nothing happened! Firewall reported me that this file is about to changing registery!
its the intel proset/wireless service. It has a major memory leak. Just close it wireless will be fine it just wont connect the same you must do it manualy
S24EvMon.exe is linked to the wifi profile when it dies it drops all information about the connection
It is harmless. If you suspect it, please check all the other processes running first and just go by process of elimination.

It is indeed causing memory leakage. To clean the situation, you just have to kill the process (from task manager), then restart the service "Intel PROSet/Wireless Service" from the Services application - this will give you a clean new version of s24evmon.
Just noticed this, but looks harmless. Does not take up any CPU and it has a fairly small memory footprint 700k

Wireless device activation monitor in Intel Based Laptops. Monitors for wireless network connections. If you turn this off.... 1. You will need to manually connect wireless, or specify particular network in the settings. 2. You will not be notified when new or open wireless networks are available. 3. the pop-up warning window that wireless networking is activated will not appear. THIS IS A NEEDED PROCESS. ........

Best practices for resolving S24EvMon issues

A clean and tidy computer is the key requirement for avoiding problems with S24EvMon. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the S24EvMon.exe process on your computer, the following programs have proven to be helpful: Security 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.
