Not Dangerous. MS Security Essentials is a top rated anti-virus. And it's FREE with daily updates. Leave it installed. Take out Norton or any other AV software that conflicts.

It is a Windows Microsoft Security Essential gui but if it is located not on C:\Program Files\ Then its a virus
Downloaded MSSecurityEssentials Last Night, msseces appeared this morning
It's Microsoft Security Essentials safe free antivirus software
if the .exe includes the switches -hide and -runkey, then Hijack This identifies it as MaCatte Antivirus 2009, rogue security software - not recommended
If it it is C:\Program Files\ and/or has -hide and -runkey in command at startup, then IT is a VIRUS!
Does a poor job on both virus and malware/spyware. Use something else.
This sat as "NonCritical_msseces.exe_f0afc3829daab2ad55ae454cdeede98423ad_17fb0b84" in C:\Users\MyUser\AppDat\Local\Microsoft\Windows\WER\ installed itself on the date of a major malware infestation -- a client was fooled by a fake Java update message that didn't even remotely look like a genuine Windows message. Id' guess some of the malware depended it, so I removed it after getting rid of the malware. Should there be a problem with Windows or any program I'll report it here.

Best practices for resolving msseces issues

A clean and tidy computer is the key requirement for avoiding problems with msseces. 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.
