Windows Live Messenger/MSN Messenger is a Microsoft software, so DUH, it isn't bad at all.
I Do NOT Use MSN Messenger At All, I Don't Even Have An Account & This File Keeps Popping Up Trying To Get Me To Install It. It's Most Likely A Virus, Since Everytime I Close It, It Comes Right Back.
can be dangerous if installing random plugins and file transfer
shows on computor as system error

task mgr showed it as a component of auridrion (malware)
If you are sensible and do not click on suspicious links on chat while using this program, you'll be fine. However it's really not that hard for hackers to wreak havoc.
This is the process of Microsoft Windows Messenger

Best practices for resolving MsnMsgr issues

A clean and tidy computer is the key requirement for avoiding problems with MsnMsgr. 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 MsnMsgr.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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
