Han Feng stood in front of the touch screen to check the computer, looking at the hexadecimal data flowing in front of him without blinking. It seemed that there was only the computer in front of him, and everything around him disappeared.

Then he started a hexadecimal conversion program in the super system, converting these seemingly meaningless data into information that the brain can understand.

After watching with all concentration for a while, the data flow in front of Han Feng slowly began to disappear, replaced by a graphical interface, which is the query interface of the Shuimu Library website. What is constantly flashing is the dynamic GIF picture on the homepage showing the Shuimu scenery.

Except for Han Feng, no one knows that this computer is actually operating normally, it is just a problem with the video output. Only Han Feng, a pervert in his brain with a binary-based operating system, can successfully convert these seemingly meaningless data streams into an image interface.

Han Feng smiled on his face, he already knew exactly what was going on.

He reached behind the computer, pressed the restart key, and then when the system was about to enter the boot interface, he quickly pressed a key on the micro keyboard to enter the EFI setting interface.

Today's computers, the software that is responsible for communicating with hardware, is no longer the kind of terrifyingly complex and old-fashioned traditional BIOS, but a graphical platform called EFI.

EFI, full name Extensible Firmware Interface, is an upgrade solution launched by Intel to completely replace traditional BIOS. Compared with traditional BIOS, EFI has many amazing advantages, such as supporting more processor architectures, faster computer startup, fully graphical interface settings, etc. Strictly speaking, EFI is actually a Unix-like embedded operating system with very powerful functions. With it, you can directly connect to the Internet without installing the operating system and surf on the network at will.

Nowadays, there are almost no traditional BIOS on computers, all of which are EFI.

Han Feng enters EFI and calls out the command console it comes with. This contains a built-in program similar to the Debug compiler. You can directly program the graphics card using assembly.

Han Feng can control the only four of his thumb and index fingers now. So when he typing on the keyboard there, he always stretched out his two index fingers and ordered clumsyly. To outsiders, he was just a guy who was more frivolous than a rookie and was messing around there. Fortunately, this was a computer for others to check at will. Otherwise, someone would definitely go up and ask him to stand aside and not break the computer.

When Du Shaofeng was fully deciding to the virus, the little lizi glanced at Han Feng by chance and saw him standing there and clicking. I don’t know what he was busy with. Although she was a little strange, she didn’t think much about it, and then she was soon attracted by Du Shaofeng’s wonderful performance.

"Enter finally finished."

Han Feng moved his sore wrists for a while. This not-so-long code took him a lot of effort. After checking it, he found no errors. He typed the Enter key.

I saw a character flashing in the console, and finally it showed: "ProgramprocessedOK! (The program was successfully executed)"

This means that the small piece of destructive code that was forcibly implanted in the system has been successfully cleared by Han Feng.

Then, Han Feng restarted the computer again.

This time, the system did not enter the previous data flow interface, but the familiar blue sky and white clouds appeared. It was not Windows XP, but Microsoft's new architecture Windows 2010 operating system. This is an operating system with Windows 7 as the core, which is much better than Vista.

Han Feng had not had much contact with computers before and was not very familiar with the Windows 2010 operating system. After all, over the years, his main energy has not been on computers, but has been busy with his body.

However, there is also a commendable tradition in the field of computers - backward compatibility.

Since the era of IBM's personal PCs, all software and hardware related to computers have maintained the "backward compatibility" principle well, that is, the software and hardware that appear later will be as compatible with the software and hardware that appear before. For example, programs written before can run well on the newly launched operating systems later.

Therefore, Han Feng can still use the previous commands. The ultimate goal of the operating system is to be simple and easy to use, so that people can get started quickly. As a top figure in this field, Han Feng is naturally no problem. He almost found what he was looking for - the command line console at the first time.

Faced with the cool interface, he still has a special liking for the console. After all, he doesn't want to spend time familiarizing himself with those graphical operations now.

After checking, there was no suspicious process in the computer, Han Feng did not check it out. He then directly called out the system log records to see what happened inside the computer during that period just now.

As Han Feng expected, there are indeed more interesting records in the system log. He found traces of the invasion of this system in dense logs.

The reason why he ran here and tried hard to fix the computer was because Han Feng had just seen many suspicious points from Du Shaofeng's movements. Many of the guy's operations were meaningless. It seemed that he was simply using some complicated and remote instructions to deceive people, blatantly bullying others to not understand his operations. Unfortunately, he encountered Han Feng.

Moreover, if this so-called "new virus" is really a virus, from its destructive power and principle, it should not be only infected by these computers. Once it spreads, the working computers over there who are responsible for applying for bank cards will definitely not be spared.

In order to confirm his suspicion, Han Feng decided to check the system log of this computer, but he actually found clues.

Han Feng followed the invaded IP all the way...

※※※

There are indeed many good things in Du Shaofeng's USB drive. Liu Yueshuang knows several of them, all of which are hacking software that he has only heard of but has never seen before. Seeing him skillfully using these software and focusing on analyzing data, Liu Yueshuang looked at him with some admiration.

Time passed by minute by minute, and so many people were waiting for Du Shaofeng to perform alone. At the beginning, Du Shaofeng's face was quite calm and composed. However, after he restarted the system several times, but the problem was still not solved, his forehead began to sweat coldly.

After watching for a long time, Liu Yueshuang saw that he was always repeating the same operation, and her confidence in him was a little shaken. She asked, "Du Shaofeng, how about it, can it be done?"

The principal was waiting anxiously, and at this time he also asked: "Student Du Shaofeng, how long will the computer be able to return to normal?"

"No...no problem, there's still one last step." Du Shaofeng simply took off his glasses, wiped them with a glasses cloth, and after putting them on again, he suddenly stood up and said a little embarrassedly, "Principal, I'll go to the bathroom first and come back soon."

On the way to the bathroom, I was about to pass by Han Feng. When Du Shaofeng saw Han Feng clicking the keyboard randomly like a local bun, he couldn't help but feel a great sense of superiority and satisfaction in his heart.

"From your virtue, you will know that you are a rookie, haha."

After mocking in his heart, Du Shaofeng turned a corner, then took the cell phone in his exit bag and dialed a number.

"Hey, master, I'm Adu..."

...

Five minutes later, Du Shaofeng returned to the registration office. At this time, he looked confident and smiled. Careful people could also find that he had carefully combed his somewhat messy hair with water.

After returning to his seat, Du Shaofeng did not talk nonsense, and directly restarted the computer, entered the DOS environment again, ran the software just now, searched for several special fields, and deleted them separately, restarted the computer.

"Ah, I've entered the system!" Liu Yueshuang said in surprise.

The principal laughed loudly: "Okay, Du Shaofeng, you did a good job! Thanks to you this time!..."

The principal praised Du Shaofeng very much, and the parents and classmates who were queuing up also began to discuss it, and the topic was about how powerful Du Shaofeng was.

Du Shaofeng followed the method just now and quickly repaired the computers responsible for registration, and the registration work that had been interrupted for a long time also returned to normal.

At this time, Teacher Lu Shen happened to come in a hurry. After understanding the situation, he also praised Du Shaofeng, saying that the problems encountered this time were very rare and he was not sure that he could solve them in a short period of time. Thanks to Du Shaofeng, otherwise today's registration work would have been delayed.

Liu Yueshuang remembered that Han Feng was still waiting for her, and saw that there was basically no problem here, so she said, "Du Shaofeng, you are so awesome! The touch screens inquiry computers over there were also infected, so I'll ask you all, I'll treat you to dinner another day."

Du Shaofeng's face suddenly showed joy and nodded without hesitation, "No problem, then just say it, Yueshuang, this time you said it yourself, don't let me go as you did last time."

"..." Liu Yueshuang was really talking casually, but she didn't expect that he would answer so quickly. Seeing that he said this, it was hard to deny it. She didn't say anything else and hurried to find Han Feng.

Du Shaofeng began to repair the library's query computer, but encountered something that was very surprised: "Huh? Why is this one not broken?" He was surprised to see that one of them had no abnormalities and was operating normally.

"Impossible." He murmured in a low voice, checking the hardware and software configuration of the computer in a comprehensive manner, and not finding anything special.

Xiao Lizi was also very strange about this situation. She said, "No, I just saw that this computer was also infected." She had checked one by one just now, and she absolutely believed that she was not dazzled just now. At this moment, Xiao Lizi suddenly remembered that she had just seen the boy who was called "little madman" by the boss. After standing here for a while, it seemed that it was this computer.

"Did he do it?" A thought flashed through Xiaolizi's mind, but she quickly denied the speculation. After all, judging from the boy's actions, he was clearly a computer novices who knew nothing. Moreover, if he really knew how to fix it, why didn't the boss Liu Yueshuang ask him for help?
