Chapter 205: Pili Beibei

But it was a bit strange. At night, Han Chu suddenly came.

Fan Wubing is still quite interested in this college classmate who is often pulled by Fan Ting to deal with his mother Zhang Mei. On the one hand, he is considering how to solve his mother's troubles once and for all. On the other hand, he is also examining all aspects of Han Chu to see if he can stand alone and be competent as a qualified department head?

"Brother Han, are you here again today?" Fan Wubing welcomed Han Chu in with a smile.

Because of the different roles, Han Chu enjoys high-quality treatment at home, and ordinary company boss-level figures cannot be treated as grandly as him.

"Xiao Han is here-" Zhang Mei has been busy recently, but when she saw Han Chu coming, she came over enthusiastically and greeted her, and then told Fan Wubing and Fan Ting to treat her well and get some fruit plates and drinks.

"Okay, okay. Very good-" Seeing his two big bosses busy making food and drink for him, and being sent to him by Zhang Mei like a gray grandson, Han Chu suddenly felt a very strange feeling, as if he was put on the stove and barbecued.

I guess the only one in the Fan Investment Group who can enjoy this kind of treatment is himself? No wonder everyone wants to make a big fortune by making a name for themselves. Seeing the two giants in the entire group serving themselves, the feeling is certainly unique. Han Chu shook his head and took a lot of effort to drive away his chaotic thoughts.

Even as their brother Fan Kang, he is still a material for work when he returns home. How could he sit on the sofa and cross his legs, waiting for Fan Ting and Fan Wubing to serve tea and water?

"What's Xiao Han doing recently? I haven't seen you come here for several days?" Zhang Mei asked very enthusiastically. She was quite satisfied with Han Chu. At least she was not ostentatious, she was more down-to-earth, had practical abilities, and had good academic qualifications. Although she started her business with Fan Ting after graduating from undergraduate studies, she later studied for a master's degree and is still continuing to study.

Zhang Mei was born in the education industry and is now in charge of basic education across the country. Naturally, she is more happy with good students. In addition, Han Chu appeared in front of her before. Now after many years, she still looks like a kind person who is not surprised by praise or disgrace, so she naturally attracts her attention.

"I'm still working on computer virus prevention and control recently. Now there are new progress and I'm preparing to report to Mr. Fan." Han Chu could not resist Zhang Mei's enthusiasm, so he hurriedly took out a backpack from behind and took out a laptop.

"Did you really bring your job?" Zhang Mei frowned immediately when she saw Han Chu take out all her laptop, and was a little dissatisfied.

What she is most concerned about now is how to solve Fan Ting's lifelong affairs. She has no interest in any computer virus. Even if the computer virus is harmful, it is not her turn to care about it, the director of the Basic Education Department. This thing seems to be something that the Ministry of Science and Technology should pay attention to.

However, after Han Chu said this, Fan Ting immediately had the opportunity to avoid her mother Zhang Mei for preaching. She immediately said to Han Chu in a formal manner, "Well, okay, let's go upstairs to have a closer talk."

"Okay." Han Chu nodded and agreed.

Zhang Mei thought to herself, it would be good. If the two of them often talk about work at home, the personal emotional problem can be solved at the same time. It can be said that it will kill two birds with one stone, which is still good.

However, Fan Ting and Han Chu had just reached two levels and said to Fan Wubing, "Wubing is here too."

"What are you doing in the past without illness?" Zhang Mei immediately objected. She thought to herself that the two of them would have to bring a light bulb if they were in love?

Han Chu explained, "Dr. Fan is a theoretical expert in virus prevention and control. Every set of our products needs to be tested and confirmed by him before they can be finalized."

Zhang Mei looked at Fan Wubing with suspicion, "No, why do you understand everything?"

Fan Wubing shrugged his shoulders and made no sound.

After the three of them went upstairs and closed the door, Fan Ting grabbed her hair a little crazy and asked, "Why is my mother getting more and more terrifying? I have to move to the company!"

Han Chu also said a little nervously, "I am also afraid of seeing Director Zhang. If this continues, I can't stand it anymore. I strongly request a replacement!"

Fan Wubing turned on Han Chu's laptop, then inserted the CD, and watched the antivirus software and instructions made by Han Chu and the others from above. After hearing the conversation between the two people, he interrupted, "Mom is not that easy to fool. Do you think she is just kept in the dark? She just doesn't want to tell this, which makes you all embarrassed. He is like this now, but I just hope you can do a real show and finally get together. But to be honest, you might as well make a few more friends. Where is such a perfect love in the world?"

"How can we get together?!" The two of them immediately spoke out at the same time and opposed.

Fan Wubing smiled and shrugged his shoulders, "Look, your reactions are the same after hearing my words. Forget it, I won't say much, you can experience it yourself."

Fan Ting and Han Chu both looked a little staring at each other. It was even more embarrassing to be preached by a guy like Fan Wubing, who had just left the category of minors, than being preached by Zhang Mei.

Fan Wubing was too lazy to pay attention to them anymore and looked at the antivirus software that Han Chu took seriously.

In the mid-1980s, computer viruses had just begun to become popular. There were not many types, but they had great harm. Often a simple virus could spread all over the world in a short period of time. After computer anti-virus workers realized the harm of the virus, they compiled a batch of early anti-virus programs in a very short period of time.

Early antivirus methods were mainly to eliminate viruses on disk. Generally, virus transmission was by adding illegal programs and data to legal files, that is, using viruses to invade certain parts of legal programs or files. Antivirus programs found these virus codes, cleared them out, and restored the original state of the file. This is the original form of antivirus software.

The antivirus program of this period was one-to-one, which means that one program can only know one virus. But soon after, the number of computer viruses expanded sharply, and it was obvious that this one-to-one antivirus method could not meet people's needs. Therefore, antivirus workers imagined whether they could develop a new antivirus product that could not only fight against new viruses but not be afraid of virus infection.

Later, this anti-virus product was designed, which was an anti-virus card, which prevents itself from being infected through hardware solidification programs. However, anti-virus card has great limitations in performance, such as the inability to remove viruses on disk.

From the late 1980s to the early 1990s, antivirus software and antivirus cards were basically used in the antivirus industry.

In recent years, the number and technology of viruses have been increasing, and antivirus and antivirus products have their own functions no longer meet the needs of users. Therefore, antivirus companies are developing three-in-one integrated antivirus products for detection, killing and prevention, organically combining various antivirus technologies to jointly fight computer viruses.

Han Chu and others have been studying virus programs for a long time, but the methods in the past were relatively single, and they were nothing more than passively searching for virus signature codes and then killing viruses.

"When we learned antivirus technology, the earliest computer viruses and marijuana appeared in China. At that time, there was no antivirus software in China. At this time, we used Microsoft's software defect debugging program debug to track and remove viruses, which became the earliest and most primitive manual antivirus technology." Han Chu knew that Fan Wubing and Fan Ting did not know about specific technical issues, so he briefly introduced his antivirus process to them. "Debug tracks the running process of the program and finds a breakthrough for the virus, and then

It is cleared through compilation functions. Debug played a major role in the early anti-virus work. However, because using debug requires proficiency in assembly language and some hard disk underlying technologies, not many people are able to use debug to kill viruses. Programmers who often used debug to track and crack viruses in the early days accumulated experience and virus samples in the long-term anti-virus work. Most of them became the backbone technical force of the computer anti-virus industry later. There are many such programmers in our anti-virus department."

Fan Wubing nodded repeatedly when he heard this. He had learned this thing before, but it was used in a shallow way. After all, when he was learning computers, the dos operating system was no longer popular. He only knew a little about debugging, and it could not reach the level of practical application.

It is said that Wang Jiangmin, the founder of the kv antivirus software, used debugging to prevent viruses at that time, and then wrote a program. When 100 viruses were killed, they were gathered together, called kv100, and all the way to the popular kv300 in the country. In this way, ordinary computer users do not need to master debugging, they can only use kv to prevent viruses.

However, with the development of operating systems and virus technology, dos virus is gradually withdrawing from the stage of history. Nowadays, anti-virus engineers rarely use debug to crack viruses, but generally use various ready-made decompilation programs.

"How effective is our product in antivirus?" Fan Wubing is most concerned about this practical issue, rather than how excellent the antivirus software in the publicity is.

Han Chu replied proudly, "We used a new antivirus engine. By constantly updating the virus signature code, we can kill various new viruses, and software upgrades are also very convenient. If the domestic Internet network is built, users can directly upgrade the virus database at home, and keep their antivirus software up-to-date at any time."

"Okay--" Fan Wubing knew that Han Chu was a real person and would never exaggerate the facts at will, so he nodded with satisfaction.

"However, we haven't given this antivirus software a name." Han Chu said again.
