Empty your Inbox regularly. Your email box is just like your regular mailbox. You can miss
important messages by leaving your inbox so full that you miss important incoming mail.
Organize your messages. Create folders for important subjects or people. Manually transfer
incoming mail into the appropriate folder.
Use 'plain text' for writing your messages.
Be careful with attachments. NEVER open an email attachment that you are not expecting.
Email attachments are the most common form of infecting a computer with a virus.
Check the 'reply to' address. In addition to 'From", "To", and "Subject", there is a header
called "Reply To", this specifies the address to which a message should be replied to. If it is
blank, replies are automatically sent to the "From" header.
Don't check your incoming email too often. Once every 10 minutes is a good interval.
If you are mailing to a number of addresses, use the BCC (blind carbon copy) feature
provided in most major email programs. That way your recipients won't have to read everyone
else's address before reaching the body of the message.
Never assume your email messages are private nor that they can be read by only yourself or
the recipient. Never send something that you would not mind seeing on the evening news.
To avoid having your mail messages look untidy and fragmented, try using a hard carriage
return at the end of each line. Formatting problems occur when your recipient has a mail
program that doesn't automatically wrap sentences. Without hard carriage returns, your
message is seen as one looooooooong sentence.
Viruses can get into your computer's hard drive in two ways:
• E-mail - The only way an e-mail message can infect your computer is if
1) the message contains an attachment
2) the attachment is infected by a virus and
3) you open the infected attachment.
When you open the attachment, it launches an application which becomes infected.
So don't open any email attachment unless you are positive that it is reliable.
• Downloads - If you download shareware or other files that are infected with a virus,
the virus will spread to your computer hard drive. Most anti virus software can be set
to scan files that you download. If you only download from reliable sources, you
shouldn't get a virus.
Computer viruses are categorized into four main types:
1. Boot sector viruses are usually transmitted when an infected floppy disk is left in the
drive and the system is rebooted. The virus is read from the infected floppy disk and
written to the master boot record of the computer's hard drive. The master boot
record is the first thing the system reads when you boot up your computer. Therefore,
whenever the computer is booted up, the virus will be loaded into the system's
2. File or program viruses are pieces of code that attach themselves to executable
programs. Once the infected program is run, the virus is transferred to your system's
memory and may replicate itself further.
