though can be dangerous if you don't understand what you are doing.
p2p file sharing. Careful what you download. mp3 have not had any problems. Wouldn't download any programs. wma, wmv, mov files (usually fake, adsponsered)
Runs fine for me, no problems. Stays as a system process after program is shut down, but can be manually shutdown from task manager.

LimeWire is a peer to peer filesharing program. Be very careful when using it is a gateway to viruses and hackers! Can be dangerous when downloading programs via LimeWire! Harmless if used to get free Music, Videos, and Pictures.

Best practices for resolving LimeWire issues

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