It is good to know that the Guest account has been disabled and/or a
password has been set on it. I am actually more inclined to think that this
may be a programming error but not necessarily a dire security threat. If
you want to verify further that your settings have not been modified, try
downloading and running HijackThis :
http://www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis . I
installed it on my own machine this evening in order to try it out and after
reading your posts. You may want to review all application programs that are
installed and that run at startup automatically. By the way, do you have a
local network set up?
Have you ever run the Belarc Advisor to inventory/audit your computer ? Try
this link : http://www.belarc.com/free_download.html . Install the Advisor
and review the output, printed out if desired.
