Yahoo! Business Email automatically scans all incoming and outgoing attachments for viruses using Norton AntiVirus, and alerts you to any known viruses it detects. Because all attachments are automatically scanned, there is no need for a specific "scan" option.

If a known virus is detected, Yahoo! will attempt to clean the file. You will not be able to download the file until it has been cleaned and is free of any known viruses.

Note: The virus scanner may not be able to detect or repair all viruses and variants. Please be aware that there is a risk involved whenever downloading email attachments to your computer or sending email attachments to others, and that, as provided in the Terms of Service, neither Yahoo! nor its licensors are responsible for any damages caused by your decision to do so. Yahoo! Business Email recommends that you never download attachments from an unknown source.
