Use this update to protect against viruses spread via attachments in e-mail. Once you install this update, you will not be able to access attachments with file types that could run executable code or change settings on a computer--actions that could allow a virus to spread.
This update contains a number of security upgrades: e-mail attachment security prevents users from accessing several file types when sent as email attachments, Object Model Guard prompts users with a dialog box when an external program attempts to access their Outlook Address Book or send e-mail on their behalf, which is how insidious viruses such as I Love You spread, Heightened Outlook default security settings increase the default Internet security zone setting within Outlook from 'Internet' to 'restricted sites'. In addition, active scripting within restricted sites is disabled by default
Note: To use the Outlook 2000 SR-1 Email Security Update, you must have 'Office 2000 Service Release 1a (SR-1a)' installed, which will require access to your Office 2000 disks.
