Untrusted Publishers
When you choose to download software from the Internet to your computer
with Internet Explorer, Microsoft Authenticode technology is used to
help verify the identity of the software's publisher. Authenticode
technology checks the software for a valid certificate or signature
(that the identity of the software publisher matches the signature and
that the signature is still valid). Note that this does not prevent a
poorly written program from being downloaded or run on your computer.
Internet Explorer's Untrusted Publishers feature allows you to block the
installation of software from publishers you do not trust. When signed
software (such as an ActiveX control) is about to be installed from a
website, Internet Explorer's Authenticode dialog will ask you whether
you want to install the software. You may choose to:
• Install the software, or
• Trust all content from that software publisher so that it will be
installed in the future without asking you, or
• Block signed software from that publisher.
When you indicate software should be blocked, the certificate used to
sign the software is placed on a block list. Any software signed with a
blocked certificate will not be installed. Some publishers use different
certificates to sign their software so you may be asked multiple times
whether you wish to block software from a given publisher. The block
list applies to all users of your computer and can only be modified by a
user who is an administrator.
