Gator also can load a spyware program called trickler which tries to connect to the net when you are on line and down load yet another spyware program.
If you are VERY careful and are happy with modifying the registry. from the start button click on Run and enter Regedit.
From the folder tree browse to
My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Run
This will list all the programs that run when you start windows.
If you see fsg.exe this is the trickler program. delete the whole entry for that line.
BE CAREFUL and don't go killing every program just because you dont know what it does. Most well behaved programs will uninstall themselves from here. It is just the #$@@ programs that hide away that you need to kill.
Do a Google search on Gator
