Dealing with Problems
(Summary)
Others (continued)
Only Windows Update programs with a high level of priority will be automatically down-
loaded (or installed).
Update programs with a comparatively low level of importance will not be downloaded (or
installed) automatically. Check regularly whether new update programs have become available.
The Security Center warning function will not operate if you are using a network domain,
for example at a company.
In Windows XP, security functions have been strengthened with regard to Web contents.
One of these is the “Pop-up Blocker,” which may prevent some Web pages from being
displayed.
If you have any problems with Web page displays (e.g., if a page cannot be displayed
correctly on Internet Explorer), check the contents of the message window displayed be-
low the address bar (called the “Information Bar”). The Information Bar shows the infor-
mation that has been suppressed by Internet Explorer.
• If the message “Pop-up blocked” is displayed:
Select the message, and select “Temporarily Allow Pop-ups.”
The blocked Popup will be displayed temporarily.
• If the message “This site might require the following ActiveX control...” is displayed:
1
Select the message, and select “Install ActiveX Control.”
2
Check “Name” and “Publisher” on the [Security Warning] screen, and execute the
installation.
• If you cannot find the Information Bar:
If you need to display the page, select the Web page link while pressing
Ctrl
. The
pop-up blocker function will be temporarily disabled.
In Windows XP, there is a function that blocks image displays in HTML e-mail messages.
To display images in HTML e-mail messages, it is necessary to access the sender’s server,
and this may cause problems in the computer.
Preventing these images from appearing can decrease the risk of attack from viruses etc.
If you need to display images, select the segment where the message “Some pictures have
been blocked?” is displayed. The images can be displayed temporarily.
If a message received in Outlook Express has contained an attachment file with an extension
such as “.exe” or “.scr” (potentially unsafe files), Windows XP blocks those files.
If you need to read the files, select [Tools] - [Options] - [Security] and remove the check mark
from [Do not allow attachments to be saved or opened that could potentially be a virus].
This message is displayed by the “Security Center” function in Windows XP.
The “Security Center” is a function that monitors the level of safety in Windows security
settings in order to operate the computer safely, for example, with regard to antivirus measures.
It checks the following three items regularly, and displays messages until the settings are
made at an appropriate level of safety.
• Firewall: Is the Windows Firewall enabled?
• Automatic Updates: Is the automatic Windows Update function enabled?
• Virus Protection: Has antivirus software been installed, has the latest version of the
antivirus software been installed, and is the real-time search function enabled (ON)?
The message “Your computer might be at risk” is displayed by the “Security Center”
function, and does not indicate an error or malfunction. The "Security Center" function
checks the above three items to ensure that your computer can be used safely, and notifies
the user if the settings are not at an appropriate level of safety.
You can continue to use the computer even if these messages continue to be displayed, but
we recommend that you follow the procedures below to minimize damage from viruses.
1
Read the message.
2
Select
(red icon) on the taskbar.
3
The [Windows Security Center] screen will be displayed.
Select [Recommendations] in [Firewall] or [Virus Protection], or select [Turn on Auto-
matic Updates] in [Automatic Updates].
If measures are not required, [Recommendations] or [Turn on Automatic Updates] will
not be displayed.
4
Execute the appropriate measures, following the instructions in the [Recommendation] screen.
When “Automatic Updates”
is enabled, will all updates
be downloaded (or in-
stalled)?
