"Xiao Yuan, what are you going to do?" Tang Xinyu was taken aback by Xiao Yuan's sudden move, and hurriedly asked.

Xia Jiuying's eyes widened, her mouth opened slightly, and she looked at Xiao Yuan with a shocked expression, because Xiao Yuan sat in front of the teacher's computer and casually inserted the floppy disk into the floppy drive.

...... uproar, there was an uproar in the computer room, not only Xia Jiuying and Tang Xinyu, but also other students were also shocked by Xiao Yuan's behavior, and they all stood together from their seats and looked at Xiao Yuan's side, and a few of them were bold, leaving their seats and walking over to Xiao Yuan's side, wanting to take a look.

"Xiao Yuan, you're too disagreeable." Tang Xinyu ran over and said loudly angrily.

"Teacher, my floppy disk is virus-free, I'll prove it to you now." Xiao Yuan looked indifferently at Tang Xinyu, who had already left his anger, and said with a slight smile.

Chi Xiang also came over, with a little disdain on his face, he wanted to see how Xiao Yuan proved his innocence.

"Quiet!" Tang Xinyu stopped the noise of the students behind him, his face sank like water, and he said with a little helplessness, "Xiao Yuan, you must know that if you can't get evidence that your floppy disk does not have a virus, you will be punished very severely, and you may even be expelled." ”

"I understand." Xiao Yuan's eyes have turned to the computer screen, his hand did not touch the mouse on the side, as a senior hacker, he has been used to using various shortcut keys to operate the computer, the mouse for him, will only reduce his efficiency, so, sitting next to the computer again, he subconsciously did so, the ten fingers of both hands brought up a few afterimages, crackling sound, he called out the command line window, and quickly made it full screen.

But he didn't expect that his actions would shock the people next to him, because his hand speed was so fast, and before everyone could come to their senses, the screen had gone black, leaving only the DOS command line prompt and the cursor that kept flashing behind it.

Seeing Xiao Yuan's computer operation so skillfully, a trace of surprise flashed in Chi Xiang's eyes, and he secretly had a bad feeling in his heart.

"The CIH virus only infects the executable files of the system, that is, those files with the suffix exe or or, teacher, you should understand this, right?" Xiao Yuan snapped and quickly typed the order while talking to Tang Xinyu.

"Hmm." Tang Xinyu was sweating in his heart, he didn't know much about the CIH virus, so he didn't know much about what Xiao Yuan said, but as a teacher, he was naturally embarrassed to say that he didn't understand, so he could only respond vaguely.

"Teacher, this floppy disk of mine is a learning software, and there is only one executable file in it, which is this." Xiao Yuan switched the current directory of the dos to the floppy disk, and then typed in a dir command, and a list of files on the floppy disk was displayed, and only one executable file run.exe it.

"Hmm." Tang Xinyu nodded, he was also familiar with the orders that Xiao Yuan typed in, so he understood that Xiao Yuan was not lying.

At this time, all the onlookers had already quieted down, quietly watching Xiao Yuan's communication with the teacher, their eyes widened one by one, and their faces were surprised, the original nerd suddenly became a computer master, which made it difficult for them to accept it for a while.

Xia Jiuying couldn't help but come over curiously, and saw Xiao Yuan flying his fingers on the keyboard, his eyes shining, and he pursed his lips lightly, thoughtfully.

"The executable file infected by the CIH virus is easy to identify, teacher, you see, this is the hexadecimal representation of the run.exe just now, if it is infected, it will find the unique feature code of the CIH virus in its hexadecimal......" Xiao Yuan typed in a command, and a bunch of hexadecimal data appeared on the screen, and then searched for the feature code of CIH, but did not search in this file.

“…… Teacher, there is no signature code found in this file, so it can be proved that there is no virus on my floppy disk, and the virus in the computer room was not brought in by me. In the end, Xiao Yuan came to a conclusion, and at the same time, there was another crackling keystroke, and the system was quickly restored to its previous window state, and the floppy disk was also taken out of the floppy drive by him and put it in his pocket.

Tang Xinyu frowned, his expression was a little gloomy, at this time, he already believed that the virus was not brought by Xiao Yuan, but he had to face another problem, if the virus was not brought by Xiao Yuan, then who brought the virus into the computer room, if this person can't find it, he, the computer teacher, will bear all the losses in the computer room now.

"Who else brought floppy disks into the computer room?" Tang Xinyu glanced at the other students in the computer room and asked in a deep voice.

These students looked at each other, all of them looked innocent, even Chi Xiang, who had been against Xiao Yuan, did not speak, but quietly returned to his seat, and the other students also returned to their seats under their leadership, Xiao Yuan also got up and returned to his seat.

"Hey, I didn't expect you to have such a high level of computer skills." Xia Jiuying said softly, looking at Xiao Yuan's eyes brightly.

"Actually, it's nothing, these are skilled jobs, and they don't have much technical content." Xiao Yuan said modestly, being stared at by a beautiful woman was something he had never experienced before, so Xia Jiuying's crystal clear gaze made him feel that his heartbeat was a little faster.

"To be too modest is to be proud." Xia Jiuying pursed her lips lightly and said with a slight smile.

"By the way, thank you just now for helping me speak." Xiao Yuan diverted the topic.

"It's okay." Xia Jiuying said with a slight smile.

"Humph!" Chi Xiang, who returned to his position, looked at Xiao Yuan and Xia Jiu Yingyan and smiled, his face was gloomy, and he couldn't help but snort coldly.

"Why, no one dares to stand up and admit it?" At this time, Tang Xinyu saw that no one answered, his face became even more gloomy, and he asked again.

For a long time, none of the students in the computer room took the initiative to show their admitted, Tang Xinyu didn't feel a little frustrated, so he rubbed his temples, waved his hand and said, "Let's do this first, Xiao Yuan, you stay, and everyone else goes." ”

When the other students heard Tang Xinyu say this, they all stood up and left quickly.

Soon only Xiao Yuan and Tang Xinyu were left in the computer room, Tang Xinyu motioned for Xiao Yuan to sit beside him, and then asked, "Xiao Yuan, where did you learn computer technology?" ”

"My dad is an engineer in a radio factory, and he usually likes to buy some computer books at home, and I read them by myself, and I have a computer at home, so I usually practice on it."

Xiao Yuan has realized that this is not a paradise at all, but for some reason, he has returned to his high school days, just like described in some novels, he was reborn, and now the time should be just after the summer vacation of ninety-eight, a few days after the start of school, although this is a bit unbelievable, but he still quickly accepted this reality, of course, rebirth is too unbelievable, he can't tell the teacher, so, for the teacher's problem, he can only make up a reason to prevaricate in the past.

"Oh, I see, you can have such a level just by self-study, you are amazing." Tang Xinyu nodded knowingly, and then praised it sincerely.

"Teacher Tang, you didn't just want to ask this question when you left me here, did you?" Xiao Yuan asked rhetorically.

"No, I want to tell you something else." Tang Xinyu only paused, and then said slightly apologetically, "Although you proved that you didn't bring the virus, it is a fact that you violated the management regulations of the computer room and brought floppy disks into the computer room without permission. ”

"So, what do I have to do so that I'm okay?" Xiao Yuan was stunned for a moment, but immediately returned to normal and asked lightly.

"First, you can find the real culprit, and second, you can fix all the computers that are poisoned, so that the school will naturally not hold you accountable." Tang Xinyu lowered his head, because he felt guilty, he didn't dare to look at Xiao Yuan's eyes that seemed to be able to see through people's hearts.

"Hmm." Xiao Yuan frowned and said, "I'm afraid the culprit is not easy to find, but I can still fix the computer." ”

"What, can you fix a computer that was damaged by a CIH virus?" Tang Xinyu raised his head violently and asked in disbelief.
