Anti-Virus Tools for Outlook

Last reviewed on January 20, 2014

Best practice for preventing virus infection is to never open an attachment from someone you don’t know. It’s a good idea to scan attachments even from known senders, especially if it’s not a file you asked to receive or the cover note is suspicious.

These tools are specifically designed to examine incoming e-mail for viruses.

The Attachment Security update prevents Outlook users from launching files directly from e-mail messages. Outlook 98 and 2000 users should make sure that they have the latest updates affecting HTML mail.

Additional tools can be found on the following pages:

Anti-virus Tools for Attachment Security – tools specific to attachments, including easy access to the blocked attachment settings.

Anti-virus Tools for Exchange server – tools for use at the server level, for Exchange and other email servers.

For information on specific viruses, see Viruses Affecting Microsoft Outlook.
