At 20, the virus will be like?

However, no one is happy about this event, because they understand that maybe tomorrow they will continue to receive warnings about a new virus. What a headache, if only 20 years ago an "accident" did not happen .

4 virus periods

In 1986, a Pakistani software company wrote a program to protect the software they just launched. But in stark contrast to the original intent, this program devastated the data of all computers that installed it.

This program sits on a floppy disk, copies itself, spreads through a computer, and destroys data. Then from the computer, it returns to other floppy disks when inserted into the machine. This "devastating program" is called Brain computer virus. This is the world's first wild-type computer virus (existing outside the laboratory), then another name "Pakistani flu".

Due to living on a "vector" as a floppy disk, the Brain virus has gradually become extinct when floppy disks are increasingly used less. Inheriting the strain of Brain virus is a super-viral strain, reigning from 1995-1999. If the Brain Virus strain can only be spread from one computer to another thanks to a virus-infected floppy disk, then the super virus is hidden in Word documents and similar forms. When sending a virus-infected document to another computer, it will immediately become infected with the virus. However, the time for the virus to spread is very long, several weeks or months.

By 1999, when the Internet really flourished worldwide, the first email worm was born called Love Bugs. "Evolution" is more than the super virus, the Love Bugs worm only takes a few hours to spread and wreak havoc on the server. The development of the Internet plus the creation of small internal networks has created fertile ground for virus development. In 2001, the first network worm named Blaster was born. It automatically invades any Windows-based computer that is not equipped with a full protection system.

Today, making the online world consume a lot of gray matter and money is trojans. Do not stop at breaking the data on the server, trojan is also designed to invade computers to steal information and personal data such as account numbers . Moreover computers are trojan trojan Enter will be under full control of the hacker!

Increasingly dangerous

Around the world, there are about 150,000 viruses, worms and Trojans at risk of devastating computers. Despite being warned a lot and anti-virus software is constantly updated, the damage that computer viruses cause is huge.

The FBI has just released data that last year, 84% of US companies were attacked by viruses. The total losses of companies are $ 67.2 billion, not including home personal computers. According to statistics in China, up to 80% of computers in the country are infected with viruses. In the UK, it is estimated that it costs about £ 3 billion a year to cure personal computers that run out of viruses. In 2006, according to forecasts, the number of hacked computers will increase compared to the previous year.

Looking back at the development of computer viruses can see that the purpose of writing viruses has changed significantly. "The most important thing in the evolution of computer viruses is the purpose of writing it. At first it was a pastime," said Mikko Hypponen, head of research at Finnish antivirus company F-Secure. Today is a benefit. "

Through Hypponen's words, it can be seen that the virus will become more and more dangerous in the future and will not stop at the computer field alone. It is possible that in the future, mobile phones are equally fertile!
