Links from search engine being redirected along with a few more things.

Either way, I still wouldn't use Limewire, and wouldn't advise you to use it neither.

Now open a new notepad file.
Input this into the notepad file:

@echo off
dir "C:\Windows\system32\drivers\etc" >> log.txt
start notepad log.txt
del look.bat
exit

Save this as look.bat, save it to your desktop.
Double click look.bat and the black cmd window will open and close, this is normal.

This is the text that this file exerted:

Volume in drive C has no label.
Volume Serial Number is 487F-6AC0
Directory of C:\Windows\system32\drivers\etc
