Because viruses don't exhib all the signs that indicate life. You might know this as MRS GREN: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretement, and Nutrition. Viruses don't respire, excrete or require nutrition, like living things do, but exhibit enough of the life signs to cause debate about where they stand.

What is a Polymorphic virus?
A polymorphic virus is an advanced type of computer virus. It is similar to an encrypted virus in that it consists of an encrypted copy of the virus and a small decrypting module but every time a polymorphic virus infects a file it encrypts itself differently and rewrites the decrypting module. A well written polymorphic virus therefore has no parts that remain the same between infections making it hard for anti-virus software to detect using virus signatures.
Is Ebola a bacteria fungus or bacteriaor virus?
It is not. HIV is a virus. It has a completely different make-up from a bacteria. The most important difference between a bacteria and a virus is that a virus does not have the ability to replicate on its own. It needs a host, another cell, to reproduce, unlike bacteria which can reproduce on their own.

Why should viresus be alive?
It's a good question. Some people argue that viruses AREN'T really alive in the usual sense but occupy a zone between life and nonlife. The tobacco mosaic virus, for instance, can sort of "dry up" into a crystal which shows no signs of life but these crystals, injected into a tobacco plant, can produce more viruses, and reproduction is a sign of living things. It might interest you to know that "virus" is from the Latin word for "slime," so people didn't think of them so much as "things" but more as "stuff."
