On my PC running Win2K, a new Administrator account, with new desktop and program group, showed up spontaneously. The computer is named "Alda". The new account showed up being named "Adminstrator.ALDA". This is in addition to the original Administrator account. When the machine boots, it boots to this new desktop. BUT, when I go to "User Accounts" on the control panel, this new account is not listed, nor can it be logged off of. I'm wondering what made this account and its desktop appear, and what can I do to get rid of it.
FYI: The computer is running Norton Antivirus and Norton Ghost at startup.
