About the types of Auto-Protect
Auto-Protect scans files as well as certain types of email and email attachments.
By default, all types of Auto-Protect are enabled. If your client computers run other email security products, such as Symantec Mail Security, you might not need to enable Auto-Protect for email.
Mac clients do not support Auto-Protect scans of email.

Table: Types of Auto-Protect
Type of Auto-Protect
Continuously scans files as they are read from or written to the client computer.
Auto-Protect is enabled by default for the file system. It loads at computer startup. It inspects all files for viruses and security risks, and blocks the security risks from being installed. It can optionally scan files by file extension, scan files on remote computers, and scan floppies for boot viruses. It can optionally back up files before it attempts to repair the files, and terminate processes and stop services.
You can configure Auto-Protect to scan only selected file extensions. When Auto-Protect scans the selected extensions, it can also determine a file's type even if a virus changes the file's extension.
For Mac clients or Windows clients that do not run email Auto-Protect, your client computers are still protected when Auto-Protect is enabled. Most email applications save attachments to a temporary folder when users launch email attachments. Auto-Protect scans the file as it is written to the temporary folder and detects any virus or security risk. Auto-Protect also detects the virus if the user tries to save an infected attachment to a local drive or network drive.
Internet Email Auto-Protect
Scans Internet email (POP3 or SMTP) and attachments for viruses and security risks; also performs outbound email heuristics scanning.
By default, Internet Email Auto-Protect supports encrypted passwords and email over POP3 and SMTP connections. If you use POP3 or SMTP with Secure Sockets Layer (SSL), then the client detects secure connections but does not scan encrypted messages.
For performance reasons, Internet Email Auto-Protect for POP3 is not supported on server operating systems.
Email scanning does not support IMAP, AOL, or HTTP-based email such as Hotmail or Yahoo! Mail.
Microsoft Outlook Auto-Protect
Scans Microsoft Outlook email (MAPI and Internet) and attachments for viruses and security risks.
Supported for Microsoft Outlook 98/2000/2002/2003/2007/2010/2013 (MAPI and Internet).
If Microsoft Outlook is already installed on the computer when you perform a client software installation, the client software detects the email application. The client automatically installs Microsoft Outlook Auto-Protect.
If you use Microsoft Outlook over MAPI or Microsoft Exchange client and you have Auto-Protect enabled for email, attachments are scanned when the user opens the attachment. If a user downloads a large attachment over a slow connection, mail performance is affected. You may want to disable this feature for users who regularly receive large attachments.
On a Microsoft Exchange Server, you should not install Microsoft Outlook Auto-Protect. Instead you should install Symantec Mail Security for Microsoft Exchange.
Lotus Notes Auto-Protect
Scans Lotus Notes email and attachments for viruses and security risks.
Supported for Lotus Notes 7.x or later.
If Lotus Notes is already installed on the computer when you perform a client software installation, the client software detects the email application. The client automatically installs Lotus Notes Auto-Protect.
