Trojan viruses Trojan viruses pretend to be other software, the name therefore taken from the Trojan Horse in Greek mythology. Trojan viruses pretend to be a legitimate piece of software, but in reality can attack your hard drives, deleting files and re- writing system files. They cause your computer to become unstable, particularly when operating system files are deleted.

E-mail Viruses Email is probably the most common method for spreading viruses. Plain text email messages don't normally spread viruses. Most email viruses are spread via attachments to email messages, or in email messages containing embedded executable code.
For example, your computer would need to open an attachment or open an html link embedded in the message. To protect yourself against email viruses it is important that you do not open attachments from senders whom you don't know, or which come from a free email source such as hotmail or yahoo. If you use an email client to check your email, avoid clients that automatically open attachments (like Outlook Express).
