About Auto-Protect and email scanning

To supplement Auto-Protect, Symantec AntiVirus detects at installation
whether you use a supported groupware email client and adds Auto-Protect for
email. Protection is provided for the following email clients:
Lotus Notes 4.5x, 4.6, 5.0, and 6.x
■
Microsoft Outlook 98/2000/2002/2003 (MAPI and Internet)
■
Microsoft Exchange client 5.0 and 5.5
■
Note: E-mail Auto-Protect works on your supported email client only. It does not
protect email servers.
Symantec AntiVirus also includes Auto-Protect scanning for additional Internet
email programs by monitoring all traffic that uses the POP3 or SMTP
communications protocols. You can configure Symantec AntiVirus to scan
incoming messages for threats and security risks, as well as outgoing messages
for known heuristics by using Bloodhound™ Virus Detection. Scanning outgoing
email helps to prevent the spread of threats such as worms that can use email
clients to replicate and distribute themselves across a network.
Note: Internet email scanning is not supported for 64-bit computers.
For Lotus Notes and Microsoft Exchange email scanning, Symantec AntiVirus
scans only the attachments that are associated with email. For Internet email
scanning of messages that use the POP3 or SMTP protocols, Symantec AntiVirus
scans both the body of the message and any attachments that are included.
When Auto-Protect is enabled for a supported email client and you open a
message with an attachment, the attachment is immediately downloaded to
your computer and scanned. Over a slow connection, downloading messages
with large attachments affects mail performance. You may want to disable this
feature if you regularly receive large attachments.
There are times, such as during the installation of new software, that you must
temporarily disable Auto-Protect.
See "Enabling and disabling Auto-Protect"
Note: If a virus is detected as you open email, your email may take several
seconds to open while Symantec AntiVirus completes its scan.
