Viruses, Worms, and Trojan Horses

Beside human and animals viruses, computer, email and phone cell also have a viruses that attack them and make a damage and even removing the software of those application or make stop work or just make can’t work properly.

The name of the viruses also similar with the animals and other egregious or flagitious animals or creature like Trojan horses, worm and others.

Worm viruses work to copy itself for example from hard disk drive C then copy to another, using email to transport to other PC like winds. Worm viruses can make damage of computer security; sometime this viruses come together with joke or software program that can download freely.

Even though software and viruses are in similar base language but viruses work infect another program, boot sector, partition sector or document that support macros, by attaching itself or inserting itself to the part of application program.

Trojan horse viruses causes damage or compromises the security of computer. The typical work of this virus is transported by individual emails. This viruses also come from joke program software.

Virology

Virology is a knowledge that study of viruses and virus-like agent or viruses history. This material include of viruses structure, viruses classification and evolution, the way of viruses to infect other creature and then exploit host cell that use for virus reproduction. Virology also study of the diseases that causes, the technique to isolate and culture them, and their use in research and therapy.

Because of the large discussion of viruses, this material often discuses on other subject and often become a parts of microbiology and pathology. The structure of viruses can be changed depend to the host of cell they infect, like animal viruses, plant viruses, fungal viruses and bacteriophages (viruses infecting bacteria, which include the most complex viruses).

If bacteria size still using of micron, viruses have size in smaller range about 30 nm to about 450 nm, this is a very very small size range. Micro size is one per million meter, and nano meter is one per thousand million meters. So a creature with thousandth time of bacteria can infect them. If infect human then this will very very small compare to human cells.

If viruses infect to human cell then virus will become of part of cells, some time unite with human DNA, this is a part of human cell. DNA can change the base structure of human DNA and a bad effect of this DNA character can derivate to the next human.

Because of nano size the technology to kill this viruses should use nano technology, many expert have use other viruses to kill viruses, of build body immune to kill this viruses. Virology that using of nano technology always develop and may on the next generation will available of nano medication to kill this infected viruses.
