After installing drivers for Linksys USB wireless "G" adapter, I get a log-in and password prompt when I reboot my machine. I went to control panel to change the way I log on and it says I have the welcome sreen disabled due to a recent file installed named GTGina.dll. I system restored to an earlier date and it went away. When I reinstalled it came back. 3 times. I am running Win XP Home.
