For all its presumed benefit, Gator is a nasty (IMHO) little spyware program. You can read about it at:

Since it's monitoring all your passwords and DOES 'call home' from time to time, your private info is potentially at risk (again, IMHO).

It can be very annoying, and hard to remove once you're fed up with it.
