Top 10 Trojans

A Trojan horse is a program that allows a hacker to make changes to your computer. Typically, a Trojan will install itself on your computer without prior knowledge or consent. Unlike viruses, a Trojan does not replicate itself. A Trojan usually disguises itself as a harmless software program and is acquired by clicking on Internet pop-ups, downloading software, or by opening an e-mail attachment. Once installed on your computer, Trojans have the ability to create, delete, rename, view, or transfer files to and from your computer. Trojans may use a program manager that allows a hacker to install, execute, open, or close software programs. The hacker may have the ability to open and close your CD-ROM drive, gain control of your cursor and keyboard, and even send spam by sending mass e-mails from your infected computer. A Trojan typically runs in the background, hiding its presence.

Worst case scenario: A third party may gain access to your computer and steal your identity or download so much spyware that it renders the computer useless
