No no!!!  Be very wary of limewire...at least wear a condom.  It is so riddled with worms, viruses, spyware, adware, STDs.  It's a nightmare.  Download what you want there if you must, but uninstall it as fast as you can after that.  However, even uninstalling won't get rid of all the cooties and skidmarks it leaves behind.  Also go into your registry and delete these: 
Go to the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. If you find the value HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run\limeshop, delete it and reboot the machine immediately. 
  
Remove these registry items (if present) with RegEdit: 
HKEY_CURRENT_USER\software\microsoft\internet explorer\menuext\limeshop preferences

Sorry for the lengthy post, but limewire is poison.
