What are hackers?
• Hackers are people who try to gain unauthorised access to your computer. This is normally done through the use of a ‘backdoor’ program installed on your machine. You can protect yourself from these by using a firewall and a good up-to-date anti-virus program. You would normally get such a backdoor program by opening an E-mail attachment containing the backdoor program. It is normal for such a backdoor program to send out more copies of itself to everyone in your address book, so it is possible for someone you know to unintentionally send you a malicious program. A few backdoor programs can work with any e-mail program by sitting in memory and watching for a connection to a mail server, rather than actually running from within a specific mail program. These programs automatically attach themselves to any e-mail you send, causing you to unintentionally send out malicious programs to your friends and associates.
