Han Feng stood in front of the touch screen query computer, looking at the hexadecimal data flowing in front of him without blinking, between heaven and earth, it seemed that only the computer in front of him was left, and everything around him was gone.

Then, he started a hexadecimal conversion program in the super system, which converted the seemingly meaningless data into information that the brain could understand.

After watching it intently for a while, the data stream in front of Han Feng's eyes slowly began to disappear, replaced by a graphical interface, and this graphical interface was the query interface of the Mizuki Library website. What keeps flashing is the dynamic GIF image on the front page that shows the scenery of Mizuki.

Except for Han Feng, no one knows that this computer is actually still functioning normally, but there is a problem with the video output, and only Han Feng, a pervert with a binary-based operating system in his brain, can successfully convert these seemingly meaningless data streams into image interfaces.

A smile appeared on Han Feng's face, he already knew exactly what was going on.

He reached behind the computer, pressed the restart button, and then just as the system was about to enter the boot screen, he quickly pressed a key on the micro keyboard to enter the EFI settings screen.

Today's computers, the underlying software responsible for hardware communication, are no longer the deadly complex and old-fashioned traditional BIOS, but a graphical platform called EFI.

EFI, or Extensible Firmware Interface, is an upgrade solution launched by Intel Corporation to completely replace the traditional BIOS. EFI has many impressive advantages over traditional BIOS, such as support for more processor architectures, faster PC boot, and full graphical interface setup...... And so on and so forth. Strictly speaking, EFI is a Unix-like embedded operating system with very powerful features. With it, you can connect directly to the Internet without installing an operating system and surf the web as you like.

Nowadays, there is almost no traditional BIOS on the computer, and it is all EFI.

Han Feng enters EFI and brings up its built-in command console, which has a built-in program similar to the Debug compiler, which can directly program the graphics card with assembly.

Han Feng can now flexibly control, only his thumb and index finger four, so when he taps on the keyboard over there, he stretches out his two index fingers and clicks awkwardly, in the eyes of outsiders, it is completely a guy who is more vegetable than a rookie messing around over there, fortunately, this is a computer for others to query at will, otherwise, someone will definitely go up and let him stand aside, don't break the computer.

When Du Shaofeng was doing his best to kill the virus, that little pear accidentally glanced at Han Feng's side, and happened to see him standing there and ordering, I don't know what he was busy with, although she was a little strange, but she didn't think much about it, and then she was quickly attracted by Du Shaofeng's wonderful performance.

"Finally finished. ”

Han Feng moved his sore wrists, such a not very long code, it took him a lot of effort, checked it, found no error, he hit the enter key.

I saw a character flash in the console, and finally it said: "ProgramprocessedOK!"

This also means that the small piece of corrupted code that was forcibly implanted in the system has been successfully removed 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, not WindowsXP, but Microsoft's new architecture of Windows2010 operating system, which is based on Windows7 as the core operating system, much better than Vista.

Han Feng didn't have much contact with computers before, and he was not very familiar with the Windows 2010 operating system, after all, over the years, his main focus has not been on the computer, but has been busy with his body.

However, there is also a commendable tradition in the computer world – backward compatibility.

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

Therefore, those previous orders, Han Feng can still be used. The ultimate goal of the operating system is to be simple and easy to use, so that people can get started quickly, and Han Feng, as a top figure in this area, is naturally not a problem. He found what he was looking for almost immediately—a command-line console.

In the face of a cool interface, he still has a soft spot for consoles, after all, he doesn't want to spend time getting familiar with those graphical operations now.

After checking it, there were no suspicious processes in the computer, so Han Feng didn't check it anymore. He then pulled up the system's log records to see what had happened inside the computer during that period of time.

And in fact, as Han Feng expected, there was indeed a more interesting record in the system log, and he found traces of the system being invaded in the dense log.

The reason why I ran here and worked hard to fix this computer was because Han Feng had just seen a lot of doubts from Du Shaofeng's actions, and many of that guy's operations were meaningless at all, as if he was purely fooling people with some complex and remote instructions, blatantly bullying others who couldn't understand his operation, but unfortunately, he ran into Han Feng.

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

In order to confirm his suspicions, Han Feng decided to check the system log of this computer, and who knew that he had really found clues.

Han Feng traced the past along the intrusion IP......

※※※

Du Shaofeng's USB flash drive, there are indeed a lot of good things, Liu Yueshuang knows several of them, all of which are hacker software that he has only heard of but has never seen before, watching him skillfully use these software and analyze the data with full attention, Liu Yueshuang is a little impressed by him.

Time passed minute by minute, so many people were waiting for Du Shaofeng to perform alone, at the beginning, Du Shaofeng still had a bit of flattery on his face, calm and calm, but he restarted the system several times, and after the problem was still not solved, his head began to break out in a cold sweat.

Liu Yueshuang watched for a long time, and saw that he was always repeating the same operation, and her confidence in him was also a little shaken, and asked, "Du Shaofeng, how is it, can you handle it?"

The principal was also waiting anxiously, and then he also asked, "Student Du Shaofeng, how long will it take for the computer to return to normal?"

"No... No problem, there's still one last step left. Du Shaofeng simply took off his glasses, then wiped them with a glasses cloth, and after putting them back on, 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, he happened to pass by Han Feng, and Du Shaofeng saw Han Feng clicking the keyboard there like a dirt bun, and he couldn't help but feel a great sense of superiority and satisfaction in his heart.

"Look at that virtue, you know it's a rookie, hehe. ”

Laughing in his heart, Du Shaofeng turned a corner, then took out the mobile phone in his pocket and dialed a number.

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

……

Five minutes later, Du Shaofeng returned to the registration office, at this time, with a confident face and a smile, careful people can also find that he also carefully combed the somewhat messy hair just now with water.

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

"Ah, it's in the system!" Liu Yueshuang said in surprise.

The principal let out a hearty laugh: "Okay, Du Shaofeng, you did a good job! This time it's thanks to you......"

The principal praised Du Shaofeng, and the parents and students who were queuing up also began to talk about how powerful Du Shaofeng was.

Du Shaofeng concocted the same method as he had just done, and quickly repaired the computers responsible for registration, and the long-interrupted registration work also returned to normal.

At this time, Mr. Lu Shen also happened to come in a hurry, and 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 time, thanks to Du Shaofeng, otherwise today's registration work would definitely be delayed.

Liu Yueshuang remembered that Han Feng was still waiting for her over there, and saw that there was basically no problem here, so she said: "Du Shaofeng, you are so powerful! Those touch screen query computers over there are also infected, so I will ask you all for dinner, I will invite you to dinner another day." ”

Du Shaofeng's face suddenly showed joy, and he nodded without hesitation: "No problem, then it's a word, Yueshuang, this time you said it yourself, don't let me go like last time." ”

"......" Liu Yueshuang really said it casually, but she didn't expect him to pick up his words so quickly, seeing him say this, it was hard to deny it, she didn't say anything more, and hurriedly went to find Han Feng.

Du Shaofeng began to repair the library's query computer, but encountered something that surprised him very much: "Huh, why is this one not broken?" He was very surprised to see that one of them was not abnormal and was working normally.

"Impossible. He muttered quietly, and after a thorough examination of the computer's hardware and software configuration, he found nothing out of the ordinary.

Xiao Lizi was also very strange about this situation, she said: "No, I saw that this computer was also infected just now." "She had just checked them one by one, and she was absolutely convinced that she had just been dazzled. At this time, Xiao Lizi suddenly remembered that she had just seen the boy who was called "Little Maniac" by the boss, standing here for a while, operating as if it was this computer.

"Could it be that he made it?" Xiao Lizi flashed such a thought in her mind, but she quickly denied the speculation, after all, judging from the boy's actions, he was clearly a computer rookie who didn't know anything, and if he really knew how to fix it, why didn't the boss Liu Yueshuang ask him for help?

Thinking of this, Xiao Lizi quickly put this idea behind her, and watched with admiration as Vice President Du Shaofeng continued to repair another query computer.
