1. Virus "very funny" or "I love you" - Do you rush to colic or penetrated deep into the heart? This is a secret, about this anyone!
This virus appeared on the Internet in 2000 and hit graphic and sound files in user systems. It could be calculated on the phrase "very funny joke" or "I love you" contained in the theme of an email. Thus, the virus was placed everywhere, the new malicious version was erased by important files required to start a computer. These are messages like "Happy Mother's Day" or Lithuanian way to get acquainted - some emails came from the mark "Let's meet for a cup of coffee", in Lithuanian, of course. When developing more complex versions of the virus, the creators took into account the unsuccessful experience of predecessors who instilled fear into users, and issued themselves to representatives of antivirus providers. They asked users to start the attached file to destroy all viruses on the computer!
2. CHLS Virus (HPS) - Heck! But Saturday was a favorite day of the week!
The first version of this virus was created for the Windows 98 operating system. The virus named its name in honor of the fatal disease transmitting rats. Huntavirus pulmonary syndrome striking the upper respiratory tract of a person, but the digital disease of the syndrome was far from being so dangerous. When in your system, the HPS virus came into action on Saturdays and turned uncompressed bitmaps of graphic objects. Simply put, he created a mirror image of your screen. Interesting fact: the virus began to distribute in the network in early 1998, long before the Windows 98 operating system was on sale.
3. Virus under the kayf, or marijuana virus - So that's why are you against drugs?
Virus from the stone century computer era. It hit the early version of the DOS system through a drive drive. For the first time, the virus was seen in New Zealand in 1988. The original version did not cause it much harm, the message simply appeared on the screen: "Your computer under the buzz. Legalize marijuana. " However, version 90s. Virus under the buzz (applied under the names Donald Duck, Hawaii, Rostov, Smithsonian, stone carrotation, etc.) caused a significant damage to the main boot record and the file posting table on your hard disk.
4. Polyposter virus (Polyposter) - Where were the laws on the inviolability of personal life when you needed them?
Remember how the talking parrot could put you in an awkward position, breaking your secrets? Actually, this virus picked up the activities of the parrot and continued his work. Known as Macrovirus, the polyposter not only hit your MS Word files, but also published them in thematic conferences on the network without your knowledge under the mysterious name "Important information about Monica Levinsky". The virus wishes in computers of all those who read these documents, which explains the connection with Levinsky - the creator of the virus, obviously, hoped to benefit from Clinton-Levinsky's scandal, which bypassed all the headlines in 1998. Among the popular thematic groups that have invited readers to familiarize themselves with your secret and personal documents (thanks to the polyposter virus), were alt.sex.stories, alt.hacker, alt.binaries.pictures.erotica, alt.fan.hanson, alt.windows95 and Alt.skinheads.
5. Chervy Karik-A - Caricature? Comic? No, Clinton.
Former US President Bill Clinton provided a bunch of information for eating a feather's greedy shark during their stay at the White House, which has proven this famous worm in 2002. The malicious program, also known as the worm of Bill Clinton and MyLife-B, activated after opening the attachment in an email message and was a caricature on Bill Clinton, playing on the saxophone, which blew the bra. The creators of this worm tried to look solid: at the end of the letter it was reported that the McAfee antivirus supplier allegedly confirms the lack of viruses in the message.
6. Worm Wurmark. - Hidden threat under the mask of fun
Appearing on the Internet in 2005, Wurmark-F worm was hidden in the image of a funny little man. If you get into your computer, the worm installed Troyan, which in turn allowed remote hackers to take possession of your infected system. Your computer had a six and was used to distribute the worm on the network. The worm also randomly deleted the files from your system and sent himself to all your contacts by mail via Outlook under your login.
7. Virus Mind (Brain) - Behind all this is the mind
The intention of the two Pakistani brothers in 1986 was originally not in creating a virus as such. The brothers created him with the intention to protect their medical programs from pirates. As a result, it led to the emergence of the first virus, threatening the security of the computer. This pretty large virus, known under different names, such as Lahore, Pakistani, Pakistani Brain, Brain-A, UIUC, Ashar and Pakistani Flu, damaged the start sector, changed the disk label to © Brain and displayed the following text:
Welcome to the Dungeon © 1986 Brain & Amjads (PVT) Ltd Virus_Shoe Record V9.0 Dedicated to the Dynamic Memories of Millions of Viruses Who Are No Longer With US Today - Thanks Goodness !! Beware of the Er..Virus: This Program Is Catching Program Fallows After These Messages .... $ # @% [Email Protected]!!
In the damaged start sectors. He also occupied 7 KB in memory and slowed down the work of the drive drive. Perhaps the brothers really did not want to harm, since another similar message issued their names, address and phone numbers with a request to contact them in order to obtain a vaccine:
Welcome to the Dungeon © 1986 Basit * Amjad (Pvt) Ltd. Brain Computer Services 730 Nizam Block Alla Iqbal Town Lahore-Pakistan Phone: 430791,443248,280530. BEWARE OF THIS VIRUS .... CONTACT US FOR VACCINATION ...
Due to the influx of angry calls from the United States and other Western countries, they had to escape and urgently change the number!
8. Trojan horse - skull - Is your phone in security?
The lightning development of mobile technologies meant that the developers of malicious programs are already somewhere nearby. In 2004, a Trojan horse appeared, he wandered freely on Nokia smartphones, which was hit by the Symbian operating system. Users whose phones struck the skulls and could see on the screen the formidable skulls and crossed bones instead of the usual icons, and the device itself worked as a simple phone. It was possible only to call and receive calls, and the functions of the smartphone were completely atrophied. Skulls and skulls and spawned a mass of alphabetic versions of type B, C and L, each of which struck the phone in its own way. The version in did the phone is useless for use, as well as, but the skulls were not displayed. Version with tried to block the action of the F-Secure anti-virus program. L was perhaps the most malicious version - she gave themselves to the antivirus program for F-Secure mobile phones. All versions of Trojan installed the Cabir worm in the phone system. This experimental malware program for mobile phones was transmitted via a Bluetooth connection and discharged the battery of the device by constantly searching other phones with the Bluetooth function to infect.
9. Trojan horse - Komar - We argue that you did not know - the bites of ordinary mosquito harmful than the bites of the malarious.
The Symbian operating system was the target for another virus in 2004 - this time the Trojan mosquito. This program designed to combat piracy hit the phones when trying to download the unlicensed version of the mosquito, games for smartphones. As soon as the virus fell into the phone, he began to send SMS messages at an excessive price for the Luxury Rooms of Great Britain, Germany, the Netherlands and Switzerland without the knowledge of the owners. It was easy to get rid of this virus - it was necessary to remove the game from the device, which would certainly have been done immediately after receiving kilometer bills for the phone.
10. Cutebot-K worm - Windows open windows - signal to the invasion of hackers?
Microsoft and disagreements - it seems that the concept of one character. The software leader has been tight criticized for creating the Windows Genuine Advantage anti-piracy program (WGA). Users complained that by not only there was a form of espionage, but it also opened the access of malicious programs to a computer via the Internet. The company has released an update to satisfy the requests of angry users, which only added Microsoft problems, since the creators of viruses took advantage of this and developed the Cuebot-K worm. The program published in 2006 was distributed over the Internet, issuing himself for the update mentioned and settled in the mailboxes from allegedly known AOL contacts. He started working at the start of the system and - oh, horror! - A message appeared that the elimination or stop of this service will lead to unstable operation of the system. Hiding under the name "Notification of Windows Genuine Advantage Check", the worm opens a secret door to access hackers who are trying to take possession of the user system.
Conclusion:
To date, do not pose a danger. Hackers are engaged in this from revenge - they want more money than glory. Much stands on the horse, so it should be sure to protect your computer from countless threats that wandered on the net days. However, it is not enough to install the best antivirus program and constantly update the package of security - be extremely careful, do not give in to the tricks of those viruses that are trying to penetrate your system, despite protective programs. As can be seen from the list, there are no absolutely safe investments in emails, and the following links are always risky on the links specified in messages. Do not lose vigilance, be always careful and intelligent in those situations when you need to protect your computer from threats.
There is an opinion that animals, plants and people are dominated by the Earth's planet. But it is not really wrong. In the world there are countless microorganisms (microbes). And viruses are among the most dangerous. They can cause various human and animal diseases. Below is a list of ten most dangerous biological viruses for a person.
Huntavirus - the genus of viruses, transmitted by man when contacting rodents or products of their livelihoods. Huntavirus cause various diseases related to such groups of diseases as "hemorrhagic fever with renal syndrome" (mortality average 12%) and "Huntavirus cardiopulmonal syndrome" (mortality up to 36%). The first major outbreak of the disease caused by Huntavirus and known as the "Korean hemorrhagic fever" occurred during the Korean War (1950-1953). Then more than 3,000 American and Korean soldiers felt the impact of the virus unknown at that time caused inner bleeding and violation of kidney functions. Interestingly, this virus is considered the likely cause of the epidemic in the XVI century, which destroyed the nationality of Aztecs.
The influenza virus is a virus that causes a person an acute infectious disease of the respiratory tract. Currently, there are more than 2 thousand of its variants, classifying according to three serotypes A, B, C. A group of virus from serotype A separated by strains (H1N1, H2N2, H3N2, etc.) is the most dangerous for a person and can lead to epidemic and pandemics. Every year in the world from seasonal flu epidemics dies from 250 to 500 thousand people (most of them are children under 2 years old and older people over 65).
The Marburg virus is a dangerous person's dangerous virus, first described in 1967 during small outbreaks in the German cities of Marburg and Frankfurt. In humans, it causes a hemorrhagic fever of Marburg (mortality of 23-50%), which is transmitted through blood, calus, saliva and vomit. Natural reservoir for this virus serve sick people are probably rodents and some types of monkeys. Symptoms in the early stages include fever, headache and muscle pain. In late - jaundice, pancreatitis, weight loss, delirium and neuropsychiatric symptoms, bleeding, hypovolemic shock and multiple bodies of organs, most often liver. The fever Marburg is among the top ten deaths transmitted from animals.
The sixth place in the list of the most dangerous human viruses is Rotavirus - a group of viruses, which are the most common cause of acute diarrhea among babies and young children. Transferred to fecal-oral way. This disease is usually easily treated, but more than 450,000 children under five years old are dying in the world, most of which live in underdeveloped countries.
Ebola virus - the genus of viruses, causing hemorrhagic ebol fever. It was first discovered in 1976 during the outbreak of the disease in the Ebola River basin (hence the name of the virus) in Zaire, DR Congo. It is transmitted with direct contact with blood, discharge, other liquids and organs of an infected person. For Ebola fever, a sudden increase in body temperature, pronounced general weakness, muscle and headaches, as well as throat pain. It is often accompanied by vomiting, diarrhea, rash, impaired kidney and liver functions, and in some cases internal and external bleeding. According to the US Disease Control Center, for 2015, 30,939 people were infected for Ebola fever, from which 12 910 (42%).
Denge virus is one of the most dangerous biological viruses for a person, causing a dengue fever, in severe cases that mortality is about 50%. The disease is characterized by fever, intoxication, myalgia, arthralgia, rash and an increase in lymph nodes. It is found mainly in the countries of South and Southeast Asia, Africa, Oceania and the Caribbean, where about 50 million people are infected annually. Virus pedestals is a sick person, monkey, mosquitoes and bats.
PCOS virus is a complex virus, a pathogen of a highly disintended disease that affects only a person. This is one of the most ancient diseases whose symptoms are chills, a pain in the field of a sacrum and a lower back, a rapid increase in body temperature, dizziness, headache, vomiting. On the second day, rashes appear, which over time turns into purulent bubbles. In the XX century, this virus was covered by 300-500 million people. At 1967 to 1979, about $ 298 million and 1979 were spent from 1967 to 1979 (in 2010, equivalent 1.2 billion dollars). Fortunately, the last famous case of infection was registered on October 26, 1977 in the Somali city of Mark.
The rabies virus is a dangerous virus, causing rabies in humans and warm-blooded animals, in which the specific lesion of the central nervous system occurs. This disease is transmitted with saliva in the bite of an infected animal. Accompanied by an increase in temperature to 37.2-37.3, poor sleep, patients become aggressive, violent, hallucinations appear, nonsense, feeling of fear, soon the paralysis of the eye muscles, lower extremities, paralytic respiratory disorders and death occurs. The first signs of the disease occur late when devastating processes (edema, hemorrhage, degradation of nerve cells) have already occurred in the brain, which makes treatment almost impossible. Today, only three cases of human recovery without the use of vaccination are recorded, everyone else ended with death.
Lasse virus - a deadly virus, which is the pathogen of the fever of Lasa in humans and primates. The disease was first discovered in 1969 in the Nigerian city of Lass. It is characterized by severe flow, damage to the respiratory, kidney, central nervous system, myocarditis and hemorrhagic syndrome. It is found mainly in West African countries, especially in Sierra Leone, the Republic of Guinea, Nigeria and Liberia, where the annual incidence is from 300,000 to 500,000 cases, of which 5 thousand leads to the patient's death. The natural reservoir of the fever of the Lassa is multi-seasy rats.
Human immunodeficiency virus (HIV) is the most dangerous human virus, a HIV-infection / AIDS causative agent, which is transmitted through direct contact of the mucous membranes or blood with a liquid of bodily origin of the patient. During HIV infection, the same person forms all new strains (varieties) of the virus, which are mutants, completely different reproduction speeds that can initiate and kill those or other cell types. Without medical intervention, the average life expectancy of a person infected by the immunodeficiency virus is 9-11 years. According to the data for 2011, 60 million people in the world in the world for all time, from them: 25 million died, and 35 million continues to live with a virus.
Computer viruses were no more than a myth of several decades ago, but over the years the situation has changed radically. In modern days, malicious programs have become a very significant threat to governments and major international corporations, for small businesses and individual computers users. All over the world there is no man who would not risen to undergo a cyber attack, regardless of how powerful antivirus software is on his computer.
1. Creeper Virus
The most first computer virus was Creeper Virus, which was found in the ARPANET network, the Internet predecessor, in the early 1970s. It was an experimental self-reproducing program written by Bob Thomas from BBN Technologies in 1971.
2. Viruses, Worms and Trojans
Currently, there are three main categories of malware-threats: viruses, worms and trojans. While their purpose and what exactly they are damaged, differ, all viruses are built on the same principles.
3. Melissa.
Melissa virus (March 1999) was so powerful that he forced Microsoft and many other major companies turn off their email systems. Mail servers of corporations did not work until the virus was completely removed.
4. Dawn of the era of personal computers
Before computer networks have gained widespread, most viruses spread through portable media, in particular through floppy disks. At the dawn of the era of personal computers, most users regularly exchanged information and programs on diskettes.
5. Viruses outlaw
Nevertheless, the creation of a computer virus today is not considered an unlawful act in the United States. Some other countries are implementing laws on computer crime that are much more stricter than in the United States. For example, in Germany, it is forbidden to exchange computer viruses, regardless of the cause, and in Finland illegal is even writing a computer virus.
6. Cybercrime
Due to the ever-growing number of computer viruses and hackers, new types of computer crimes arise. Nowadays, the so-called cybercrime covers a wide range of classes, such as cyber terrorism, cyber extortion and cyberwoman.
7. Losses - $ 38 billion
The most expensive computer virus of all time was the worm of MyDoom, which was launched in January 2004. He led to losses in the amount of $ 38 billion. According to preliminary estimates, this virus has infected 25% of all email letters.
8. Anonymous.
In fact, it is very easy to become a member of Anonymous - the most famous international network of hackers. But only a few members of this organization are elite hackers who can use the shortcomings of security in computer systems and write viruses.
9. Activation through the link
It is impossible to infect the computer virus, simply reading email. The virus is activated only by clicking on the link or when opening an infected attachment.
10. Frightening speaker
By 1990, there were only about 50 well-known computer viruses. In the late 1990s, the number of viruses increased sharply to more than 48,000. Today, about 6,000 new viruses appear every month.
11. Caution, children!
Some viruses are children who create viruses to simply test their programming skills. About 32% of all computers in the world (that is, almost every third computer) infected with any malicious program.
12. Antiviruses are not comprehensive
Despite the maximum efforts of researchers and developers in the field of computer security, no one of the existing varieties of anti-virus software is not able to determine all computer viruses.
13. VBA Microsoft Office
Created by the Philippine programmers Rionel Ramones and Onelem de Gruzen in 2000, a computer worm known as Iloveyou or a "letter of happiness" became one of the most dangerous computer viruses in history. The virus infected about 10% in the world connected to the Internet computers at that time. Losses of PC users worldwide amounted to more than $ 10 billion.
The computer was today an integral part of a person's life. And scientists work on improving supercomputers and dream that they will find answers to.
Surely, each of you came across viruses on computers. Now, of course, they divorced a huge amount. And once it was in the wonder. Consider some interesting facts about computer viruses that you did not know.
1. The world's first virus was presented on November 10 in 1983 by Fred Coen at a computer security seminar. And today it is already known about more than a few thousand types of viruses, daily affecting electronic devices.
2. According to statistics, every third computer is subjected to viral attacks at least once within the year.
3. According to the research, the specialist was found out that antiviruses are observed in 1-2 days. Due to this, 15% of viruses can safely penetrate into a computer despite anti-virus protection. After all, daily hackers come up with increasingly sophisticated ways to infect equipment.
4. Every year, computer viruses make a global economy financial damage in the amount of $ 1.5 trillion.
5. The most destructive in history virus had the romantic name "I Love You", also known as Loveletter. Letters with this inscription began to be sent from the Philippines on the night of May 4 to May 5, 2000 users of the whole world. Nothing suspected users opened a letter in which a cunning virus was hidden.
When opening an attachment, the virus immediately created a copy of himself and sent to all user contacts. So the computer virus "I Love You" was able to damage the global economy in the amount of 10-15 billion dollars, hitting more than 3 million computers. Becoming the most expensive ever-existing virus in the world, Loveletter entered the Guinness Book of Records as the most destructive virus in the world.
6. But the most secure virus is considered a virus called "Blaster" also known as Lovsan, Lovesan or MSBLAST. The worm epidemic was observed in August 2003. The story began with the fact that the XFocus team found a vulnerability in Windows operating systems associated with buffer overflow. Due to this vulnerability, viral programs appeared, the most famous of which was the blaster worm. The worm falling into the computer began to generate random IP addresses and after that I was looking for vulnerability in the victim's system, and finding the electronics infected and the cycle was repeated repeated many times.
Due to this spread, 300 thousand computers suffered, 30 of which in Russia. For users, the virus was safe, except because of the virus accounted for all the time to restart the computer. The goal of Blaster was the attack of Microsoft servers. However, the company was able to reduce the damage from worm to a minimum, thanks to the temporary closing of the servers. The idea of \u200b\u200bthe virus was that the worm contained a hidden message in the code, addressed to Bill Gates: "Billy Gates Why Do You Make This Possible? STOP MAKING MONEY AND FIX YOUR SOFTWARE !! » ("Billy Gates, why do you make it possible? Enough to make money, correct your software!").
The creator of the virus was the American schoolboy Jefffy Lee Parson, who was put on a year and a half to prison and commissioned 225 hours of public works.
7. The fastest virus in the world - SLAMMER, is translated as a prison. In minutes, the computer worm was able to infect more than 75 thousand computers.
8. The famous Programmer Peter Norton in 1988 made an interesting statement. He believed that viruses do not exist at all and compared computer malicious programs with the myths about crocodiles living in New York sewers. However, this did not prevent Peter to start his own anti-virus project called Norton Antivirus.
9. The first large-scale viral attack on the network occurred in 1988. She was called "Chervie Morris." The virus infected more than 6 thousand computer systems in the United States (including the NASA Research Center), paralyzing their work. So "worm of Morris" brought financial damage in the amount of $ 96 million.
10. Computer viruses except destruction, gave the life of the new sector of the economy - annually antivirus companies earn up to 2 billion dollars at the production of anti-virus software.
Top 10 Interesting Facts Pro Computer Viruses 
Good all the time of day, my dear friends. With you as usual Dmitry Kostin and today on the calendar we have Monday. So it's time for us to relax a little before the long working week. I thought for a long time, on what topic today to write an article, and I remembered how not so long ago it was discovered. So I decided today to write about the most interesting facts about computer viruses. I hope you will enjoy.
- In essence, there are three types of computer threats: Trojans, worms and virts. Each of these species is designed to perform different tasks. But despite this, in the conversational speech, they are called viruses.
- The first viruses were harmless. All their harmfulness was that the inscription was shielded on the computer, which did not carry any consequences. One of these VIPYS was a popular Creeper, appeared in the 70s. When he fell to the car through a modem, "I" M Mo Creener ... Catch Me If You Can "appeared, that is," I am a cryper ... Catch me if you can. "
- The first virus that has become infected personal computers has become ELK Cloner. This event occurred in 1981. This virus could have blinking the text on the screen and could turn the images. At that time, no one suspected about such malicious codes, so such a move caused panic. Some even assumed that this is the intelligence intelligence.
- But despite the fact that the Virus themselves appeared earlier, this term was officially introduced in 1983 and meant "self-magazing computer programs". A little later, Frank Cohen made a more scientific justification for this term, that this is an application that can inflict other applications using their modification for subsequent distribution.
- Despite the fact that today there is a huge number of good and even cool antiviruses, anyway, many viruses penetrate them bypass. This happens as a consequence that the antivirus base exists almost the next day, since every day more and more new types of infection appear.
- In 1988, the famous programmer Peter Norton (by Norton Commander, Norton Utilites, Norton AntiVirus) with foam at the mouth argued that computer viruses are a myth, akin to the myth that crocodiles are found in New York sewages, and they are simply not exists. But despite his statement, his own company, after a period of time, produces his own antivirus.
- Evgeny Kaspersky first met the viruses in 1989, when the famous Cascade virus appeared on his work computer. It was after that he decided what will be carried out in the future, namely to develop antivirus software. Later, as far as you already understood, he founded the famous "Kaspersky Lab".
- The famous PC Today magazine made it toward each disk edition. But in 1990 an incredible case occurred. It turned out that the floppers that came with a specific issue of the magazine contained VPYC. A total of 50,000 issues of this room were sold.
- Previously, to update Kaspersky Anti-virus bases, it was necessary to upload a large file containing all old and new threat signatures. And it was necessary to do constantly, which was a rather heavy process. But since 1992, this task was much simplified. From now on, it was not necessary to overwrite the base file. It was only necessary to download a tiny addition, which contained protection from the newest viruses.
- According to statistics, the site that was mostly subjected to viral attacks, which is known to all amazon.com.
- Russia is in second place on registered computer attacks immediately after the United States.
- Do not be afraid to open suspicious letters in email. The letters themselves cannot be infected. But the opening of attachments or the transition by reference inside the letter may be dangerous, so do not lose vigilance.
- New vips are written simply with an incredible speed. Imagine, by 1990 there were only about 50 viruses, and by the end of the 90s their number increased almost to 50,000.
- To detect weak points and vulnerabilities in your system, Facebook pays $ 500 to someone who can hack it.
- There is no antivirus program that can cope with all viruses.
- The most famous virus is still known to many I Love You, which was created in 2000. Then he was able to infect more than 3 million computers worldwide.
Sincerely, Dmitry Kostin.
