Big problem! I installed and ran Norton Antivirus 2006 on my home computer. Now I get the welcome screen with all the users but then I get a message when I try to log on as any user: "Explorer exe. unable to locate component. This application failed to start because WININET.dll was not found. Re-installing the application may fix this problem." Someone said it's the Windows Initiation file. I can get to task manager, but can't bring the computer up in safe mode. Any ideas?
