We're running Windows XP. We have 4 different user accounts; mine, which is set as administrator, two for the kids, set on limited, and my husband's, set as administrator. Within the past week or so, when at least one of the kids' accounts and my husband's account starts up, the regular display screen will appear momentarily, but the screen will then go black and the message "! have noth!na say bam st!ll ZaCker!" appears in red print. Does anybody have any idea where this came from and how to get rid of it? The screen is completely frozen- not even the bottom task bar with the start button appears- and you have to use the task manager to end the task. The only task it says it is running is explore.exe. I would appreciate your help!!!! Thanks
