Ok maybe someone can tell me what's going on here. I went to change the password on my one and only user account on this comp (outside the main admin account which is only available via safemode and doesn't appear under the user account list) to discover there was another account listed under the user accounts area. This new account doesn't appear on the welcome screen, is a limited account and is password protected. I've ruled out the possibility that it could have been created by someone else as no one else has used my computer since I reformatted it, and I've ruled out any known viruses as nothing came up on a system scan. The name of the account is ASP.NET MACHINE A... if it helps. Thnx for any help on this.
