I have three users defined on my computer. Each has a user name and password for access. The windows guest account has been deactivated. About two weeks ago I noticed when starting Windows XP there is a new user account appearing. It is called "Internet Guest Account". I can delete this account and its files but when I shut down the computer and restart it appears again. I am concerned that this may be spyware that was installed without my knowledge.
I would appreciate any suggestions and help.
