What is a Computer Virus?
A computer virus is a program that can modify programs and data files. It is designed to replicate and infect as many files as possible. Viruses can be extremely destructive to your data and hardware. A virus is also known as malware, malicious software. Other examples of malware are worms and Trojans.
Worms copy themselves from system to system rather than infiltrating files. Email worms send copies of themselves to users listed on the infected machine's address book.
Trojans are associated with remote access programs that perform illegal operations such as stealing passwords or allowing compromised machines to be used for targeted denial of service attacks. A denial of service (DoS) attack involves flooding a target system with so much data, traffic or commands that it cannot perform its core functions.
