As mentioned in the section on attachments, one way that computer viruses spread is through email. You should purchase and use an antivirus program to scan and check not only email attachments, but other documents that you share (for instance, via a floppy disk). Another downside to email is the amount of electronic junk mail (called spam) that you receive. You can easily get unwanted messages from people and companies. To handle this type of mail, you can block senders and use an antispam program. Blocking SendersOutlook Express enables you to block mail from certain senders. If you receive an email message from someone on your blocked list, it is placed in the Deleted Items folder. The message is in boldface type so that you can find and review the message. If it's not spam, you can undelete it. (Sometimes, messages get tagged as junk mail by accident.) To block a sender, follow these steps:
If you want to unblock a sender, you can remove him or her from your Blocked Senders List. Click Tools, Message Rules, Blocked Senders List. Select the sender and then click Remove. Click OK to close the dialog box. Using an Antispam ProgramOutlook Express's spam features are not that extensive, so you may want to use a special program for handling junk mail. Many antivirus programs or Internet security suites include features for dealing with junk mail. For instance, if you have Norton Internet Security, you can use Norton AntiSpam to handle junk mail. This program adds an icon to your mail program, and you can use this program to flag certain messages as junk mail. note
When it receives messages it thinks are junk mail or that have been flagged as junk mail, Norton AntiSpam places them in a special junk mail folder. You can open this folder and review and delete messages as needed. If you have an antispam program, follow the specific instructions for turning on and configuring that program. Figure 7.16, for instance, shows the options for turning on Norton AntiSpam. You also can create a blocked sender list (like in Outlook Express), and you can create rules that will find and flag certain messages as spam. To do so, create mail rules from the Spam Rules tab. Figure 7.17 shows the first step in creating a spam mail rule. You enter the text to match and in the subsequent steps select what to search (entire email, sender's name, subject line, recipient, and/or body text) and how to classify the message (as spam or not spam).
