напишите развернутую аннотацию к тексту, About 16.000 viruses have been encountered by various antivirus research labs, and that number is expected to continue growing rapidly. Though it is difficult to predict what the next major class of viruses will be or when it will hit, the place it hits is likely to be the Internet. Viruses are spread due to human contacts, such as exchanging disks or posting an infected file on a server. But they move from system to system also by themselves actively seeking out new computers to infect. IBM researchers have proposed an automated system that can identify new viruses as well as develop and disseminate the antidotes. The software will be able to identify a previously unknown virus by either analyzing changes to a file or studying the characteristics of a file for code common to viruses. When a potential virus is identified, the infected file will be sent to the virus-lab computer. If the virus is known but not recognized by the user's system because of out-of-date software, updated antivirus data will be sent back to the user. If the virus is truly unknown, the virus-lab computers will let it spread within a secure environment and then study the way the virus behaves, extracting its signature based on the common characteristics of the infected files. The signature will be tested to ensure it didn't misidentify clean files as infected. If the signature passes, it would be sent back to the machine on which the virus was originally identified and the virus will be removed. IBM estimates that the entire process should take only about 3 minutes. Within a day, the updated virus signature will be sent out to all computers running IBM's software, protecting them from possible infection. This automated system will be faster than the manual process used in today's antivirus software, which typically takes several weeks to a few months to send new virus signatures to all subscribers. Other disaster faces the antivirus community in the coming years. As computer prices continue to drop and more users get connected, the general level of user sophistication goes down. As a result, hoaxes have begun to spread around the Internet like wildfire. They are so prevalent that most users are more likely to be bothered by hoaxes than by actual viruses. A hoax typically takes the form of an e-mail message: it warns the user of a virus spreading as part of another e-mail message that will cause damage to the user's computer. The message urges users to send the warning to all their colleagues. In fact there is no virus, but the hoaxer's message can take on viruslike characteristics as it replicates from system to system via e-mail. Although it is possible for a virus to spread via e-mail, such a virus has yet to be seen and studied. Most users do not understand the difference between viruses and other malicious threats. Because of this, anti-virus vendors will have to continue extending their products to address more types of security problems, as well as to better detect the rapidly increasing number of viruses.

Outward appearance
In the books, Hermione is described as having "bushy brown hair"and brown eyes. Her front buck teeth, already very large, grow uncontrollably in Goblet of Fire after she is affected by a spell cast by Draco Malfoy. Madam Pomfrey attends to her in the hospital wing and, at her request, shrinks the teeth down to a normal size that matches her mouth. In the films, her hair is less bushy and she always has regular teeth.
There is controversy over whether Hermione's skin color was ever categorically established in the books. Some take as proof a line from Prisoner of Azkaban: "Hermione's white face was sticking out from behind a tree." They interpret this to be a direct description of her skin color. Others interpret it as a description relative to her usual complexion, arising due to fright and anxiety as she watches Harry Potter's attempt to save the hippogriff Buckbeak from execution. J.K. Rowling herself states that Hermione "turned white" in that she "lost colour from her face after a shock."
Conversely, another description from early in Prisoner of Azkaban can also be cited: "They were there, both of them, sitting outside Florean Fortescue's Ice-Cream Parlour, Ron looking incredibly freckly, Hermione very brown, both waving frantically at him."Some claim that this is a direct description of her skin color, while others claim that it's a relative description of the results of a tan acquired over the summer break.
Personality
Hermione's most prominent features include her prodigious intellect and cleverness. She is levelheaded, book-smart, and always very logical. Throughout the series, Hermione uses the skills of a librarian and teacher to gather the information necessary to defeat Voldemort, the "Dark Lord". When in doubt, it is to the school library that Hermione always turns to. She is often bossy yet unfailingly dutiful and loyal to her friends—a person who can always be counted on. J.K. Rowling stated that Hermione is a person that, "never strays off the path; she always keeps her attention focused on the job that must be done." Despite Hermione's intelligence and bossy attitude, Rowling says that Hermione has "quite a lot of vulnerability in her personality," as well as a "sense of insecurity underneath," feels, "utterly inadequate... and to compensate, she tries and strives to be the best at everything at school, projecting a confidence that irritates people." During her Defence Against the Dark Arts exam at the end of Harry Potter and the Prisoner of Azkaban, Hermione reveals that her biggest fear is failure after a Boggart takes the form of Professor McGonagall and tells her that she has failed all her exams.
Hermione is extremely compassionate and is very quick to help others, especially those who are defenceless, such as Neville Longbottom, first-years, House-Elves, fellow Muggle-borns, half-giants like Hagrid, and werewolves like Lupin. It was revealed by J.K. Rowling after the publication of the final book that Hermione's career in the Ministry was to fight for the rights of the oppressed and disenfranchised (such as House-elves or Muggle-borns). Hermione is also very protective of her friends and values them so much that Rowling has suggested that, if Hermione had looked in the Mirror of Erised, she would have seen Harry, Ron, and herself "alive and unscathed, and Voldemort finished." Hermione has also learned to ignore what bullies such as Draco Malfoy say to her, often preventing Harry and Ron from retaliating and thinking of some way to outsmart him. She accepts her status as a Muggle-born witch, and states in Deathly Hallows that she is "a Mudblood and proud of it"
