Chapter 2282: Virus and anti-virus

The computer startup is a complicated process. This is not an ordinary electrical appliance. It can be used after turning it on. After turning on the computer, the first step is to power on and self-check to check whether the components are in good condition. Then, transfer data from the boot area of ​​the hard disk. Load the memory, etc., before the computer's operating system is started, a boot system must be started. This system is encapsulated in the computer's BIOS chip.
Essentially, it flashed the BIOS program, which is still a software virus, but it makes the entire computer hardware unable to work. This is not to say that reinstalling the system can be solved, but the entire computer cannot be used. I can only go to the hardware repair department to remove the BIOS chip and replace it with a new one. Because this virus is so powerful that some motherboard manufacturers have invented dual BIOS motherboards. Once one of them is broken, you can Change to another, a small virus, which makes people smell bad.
The virus named CIH was only created by a college student on Treasure Island. It is usually hidden in the hard disk until the 26th of each month. It comes out to cause damage, using the Internet and pirated CDs, etc. , Quickly spread out, and in a short time, it became the most famous virus in the world.
The influence of this guy is quite huge.
Even after it arrives, the BIOS exits history and is upgraded to UEFI, and there are still viruses against it.
"Yes, computer viruses have become the worst enemy of our computer systems." At this moment, someone below said.
Qiu Xiaojun, now Qiu Xiaojun, is already a leader in the software company affiliated to Hanxin Technology Co., Ltd. He is responsible for the projects he is responsible for, and there is nothing that can't be done. The operating system they jointly developed is also well received.
Generally speaking, computer systems are constantly evolving, hardware is evolving, and software is also evolving. Therefore, it took one minute to boot up ten years ago, and one minute later, because computer systems are becoming larger and larger.
Just look at the size of the software. Win98 only has one or two hundred megabytes. When it comes to winxp, there are five or six hundred megabytes. When it comes to win7, it is a few Gs. The system interface is getting more and more fancy, and the things inside are more and more More and more, bigger and bigger.
However, the domestically produced operating system is not the case. While the computer hardware is developing rapidly, the software is not getting bloated. On the one hand, it does not pursue the bells and whistles of the interface. The interface is still minimalist, the same as it was a few years ago. Of course, with the development of the system, the picture must be more and more detailed, but what special skin, None of these.
At the same time, the kernel of the system is also constantly improving. It is not a simple piling up and simply adding in new things that come out, but a perfect integration and constant modification of the code, thus realizing the increase of functions. At the same time, the system It is still very smooth.
As one of the designers of the system, he of course also knows that the system still has many vulnerabilities. These are inevitable. Then, as long as the vulnerabilities are found, they may be infected with viruses, be invaded, etc. It is a war without gunpowder and a war that will never stop.
"Our system has built-in anti-virus software, but everyone knows that once the anti-virus software runs, it will seriously slow down the speed of the system." Qiu Xiaojun continued: "Moreover, anti-virus software has a lag. Generally speaking, , There is a virus first, and then there is a way to deal with it."
The system does not have anti-virus software, and the operation is quite smooth. After the anti-virus software is turned on, those with low configuration can almost not run. The reason is simple, because the anti-virus software needs to monitor all the actions of the system, which is like an additional increase A system is normal, which will seriously hinder the operation of the system.
"Yes, this is a problem, so I have a suggestion." Qin Guan said: "When we are studying anti-virus software, we also study various viruses, which can be specially organized within our company. A virus offensive and defensive laboratory is researching viruses and cracking viruses at the same time. It is like our military. The red and blue sides use exercises to find each other's shortcomings, and then make progress together."
There is a famous saying in later generations that the biggest virus maker is the anti-virus software company, and the anti-virus software company constantly exiles viruses in the market. In this way, users want to protect the security of their computers and have to upgrade them constantly. Anti-virus software, constantly buying the latest anti-virus software.
Qin Guan doesn't know whether this statement is correct, but now, Qin Guan has a very bold idea in his mind. Since the air defense system of the silly Damu was poisoned because of the purchase of a printer from the country, the system was paralyzed, then, When the time comes, can you reverse this scene and let Silly Damu fight back with a clean and neat little counterattack?
Of course, even if there is no such idea, the attack and defense of the virus must be studied. If you only engage in anti-virus software and don't know how to make the virus, you can't face each other.
"Xiaomin, you are specifically responsible for the anti-virus software, so let you study the various aspects of virus manufacturing," Qiu Xiaojun said.
In the past few years, Qin Guan did not pay too much attention to the development of his own institutions, especially Hanxin Technology. When handed over to Zhang Gong and the others, Qin Guan was relieved, and did not know that in just a few years , Qiu Xiaojun has grown up, and he can be regarded as a person in charge of the project.
The person called Xiaomin immediately nodded in agreement. When the person’s mental point was scanned, the name floating on it made Qin Guan relax immediately. Xiaomin, a famous virus expert, that Xiaomin Technology, It's specialized in anti-virus software, and if you leave it to him, you can't rest assured.
"Also, these are the company's internal secrets. Please pay attention to the company's confidentiality procedures." Qin Guan said: "Especially the virus we researched by ourselves, once it spreads, it will bring an irretrievable ending. Then, The company will deal with it in accordance with the law."
This must not go wrong, otherwise, it may cause chaos in the society, they all know that they know their own system, for tat, when it is written, it is also very lethal.
Moreover, this kind of thing, spreading out, will also bring about reputational impact. In fact, Qin Guan is even more looking forward to the emergence of specialized units of this kind in the military. The offensive and defensive warfare of cyber experts is also an ability that the military must possess. Of course, as long as the country needs it, he can send this department in the company anytime. For the troops.
