Most antivirus programs identify m.exe as malware—for example Symantec identifies it as Trojan Horse, and TrendMicro identifies it as TROJ_AGENT.AYGZ.
The m.exe file is a software component of Virus/Malware.
"m.exe" is an executable file that is located in Windows operating systems for a malware infection by an unknown developer. It is a Win32 (PE32) console executable for the MS Windows (GUI) Intel 80386 32-bit Mono/.Net assembly. The file is part of a USB insertion setup for various devices in which the AutoRun file is edited with the "m.exe" command. It then begins to inject the infection into the system that redirects malware prevention/antivirus websites and also stops or prevents antivirus/malware programs from running or launching. Because the file has a generic name, it can also be part of other programs not related to malware, such as games like Warfare Incorporated. However, it is usually a virus infection most of the time.

A clean and tidy computer is the key requirement for avoiding PC trouble. 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.
