What is a Virus?

A computer virus is a program of executable code that has the ability to replicate.
Like biological viruses, computer viruses can spread quickly and are often difficult
to eradicate. They can attach themselves to just about any type of file and are
spread as files that are copied and sent from individual to individual. Some computer viruses can also destroy files, reformat your hard drive, or cause other damage. If the virus does not contain a damage routine, it can cause trouble by consuming storage space and memory, and degrading the overall performance and resources of yourcomputer. Several years ago most viruses spread primarily via floppy disk, but the Internet has introduced new virus distribution mechanisms. With email now used as anessential business communication tool, viruses are spreading faster than ever. Viruses attached to email messages can infect an network or your computer in minutes, costing companies millions of dollars annually in lost productivity and virus extraction expenses.


What is a Wabbit?

Wabbit's are rare. Oddly enough they don't do much unless it's on your computer. They don't try to spread to other computers, but they can be devastating to your computer.

What is a Backdoor?

Backdoors are a lot like Trojans and worms, except they open a backdoor to your
computer allowing hackers into your computer to load viruses or to send spam through your computer.
