What are you referring to when you say "it"?
If this is what I think it is, it's just a Windows security notification that pops up because LCPD:FR is made by someone it has never heard of and could potentially contain malware. This is to prevent you from downloading what you may think is something like a Java Update when it's really just a fake trying to look like the official thing. There is usually an option along the lines of "download anyways" or something similar to get past the notification.
Again, I don't really know what the problem is (perhaps post a picture?), so this may not be accurate at all, but this is what it appears to be.
