HELP! (Security Warning window)
 

Can someone help me??? I am trying to download limewire, but everytime i get this window that says:

Security Warning

Windows has found a problem with this file.

__________________________________________________ _________________
Name: LimeWireWin.exe

Publisher: Unknown Publisher

(Then you can click OK under those two options)

at the bottom of the window it says:

This file was blocked because it does not have a valid signature that verifies its publisher.

Thanks.
