"Yes, I can fix it." Xiao Yuan nodded in confirmation.

Tang Xinyu felt a little incredible, stared into Xiao Yuan's eyes, and was silent for a long time, he tried to find a trace of a lie in the eyes of this student, but in the end he had to give up.

"Teacher, I can help you fix your computer, but I also want to ask for an explanation." Xiao Yuan saw Tang Xinyu look away, and said lightly again.

"What's that?" Tang Xinyu asked, at this moment, he didn't realize that the initiative of the words had been unconsciously transferred to Xiao Yuan's hands.

"If someone asks about today's incident, you have to help me prove that I didn't spread the computer virus in the computer room." Xiao Yuan said indifferently, he is a hacker, not a hacker who destroys everywhere, which he cares about very much, and the crime that changed his fate in his previous life is no longer willing to bear in this life.

"That's no problem, as long as you can fix the computer, I'll say I asked you to bring in the floppy disk." Tang Xinyu was undoubtedly affected by Xiao Yuan's calm emotions, and began to believe that he could fix the computer, so he agreed without hesitation, after the computer was repaired, the school would definitely not pursue anything more, and he was no longer responsible, so naturally he would not ask any more CIH questions.

"Alright then, let's get started." Xiao Yuan has always been a man of action, no longer talking nonsense, stood up, sat down in front of the previous teacher's machine, and said, "I want to write a few tools first, teacher, you wait a minute." ”

"What language do you use, do you want me to prepare a programming tool for you?" Tang Xinyu asked, you know, in the school's programming class only taught a simple basic language, using basic to write a scanner to find CIH viruses, obviously unrealistic.

"Compilation." Xiao Yuan spit out two words, and quickly called up the command line window again, and switched to full-screen mode, he had some preference for this kind of all-black screen, because he felt that this environment could allow him to calm down quickly.

Xiao Yuan typed in the debug command behind the command line, which is an artifact-level tool that allows you to directly operate on the hardware, and of course, you can also write assemblers directly in it.

Tang Xinyu was even more surprised when he saw Xiao Yuanyun's fingers flying, and the lines of assembly code were knocked onto the computer screen, this student gave himself too many surprises today, so that he couldn't think of what to say, but he was thinking in his heart, there will be such a big cow in the class in the future, will it be too stressful to teach them by himself?

"Teacher, don't be stunned, unplug all the network cables of all the computers in the computer room, and remove the hard disks of the poisoned computers." In order to speed up, Xiao Yuan commanded.

"Oh." Tang Xinyu responded, this kind of simple work is pediatrics for him, and turned around and went busy according to Xiao Yuan's instructions.

Xiao Yuan first gave the teacher an immune patch to prevent the machine from being infected by the CIH virus, and then wrote two gadgets, one of which is used to kill the CIH virus on the hard disk, and clean the junk data written by the CIH virus on the hard disk, and the other tool is the BIOS recovery program, because the CIH virus is bad, mainly because it can destroy the BIOS chip on the motherboard, and those machines that can't be started are actually the reason why the BIOS is destroyed.

Since he hadn't written these tools for a long time, Xiao Yuan only had some principles left in his mind, so he spent a certain amount of time debugging both tools, and when he withdrew his gaze from the computer screen, Tang Xinyu had already completed the work Xiao Yuan had explained, standing aside and waiting for him.

After the tool was written, Xiao Yuan freed his hand, and naturally it was not good to tell Tang Xinyu to do it again, so he turned off the teacher, picked up a screwdriver, opened the case of the teacher's machine, picked up a hard disk infected with a virus next to it and connected it to the case, and then turned it on again.

"Xiao Yuan, if you do this, will you also infect the teacher's machine?" Tang Xinyu asked worriedly.

"No, it won't." Xiao Yuan said very firmly, but did not explain the reason.

"Why?" Tang Xinyu was very curious, and asked like a primary school student, at this time, the roles of the two teachers and students had naturally changed.

"I've patched the teacher's machine, and the CIH virus won't infect the machine again until a new variant appears." Xiao Yuan explained.

"Immunity patch?" Xiao Yuan's explanation made Tang Xinyu even more curious.

"Yes,......" Xiao Yuan waited for the computer to boot up, and briefly explained the principle of CIH infection to Tang Xinyu.

"What you learned from your dad?" Tang Xinyu was shocked in his heart, and became strongly curious about the source of Xiao Yuan's knowledge, so he asked, at the same time, the image of Xiao Yuan's father has risen to the height of a master in his heart, just imagine, if his son can have such good computer technology, then his father is not even more powerful, but he can't imagine that although Xiao Yuan's father is a radio engineer, his understanding of computers is only at a rudimentary level, and he is not a master at all.

"Yes." Xiao Yuan replied casually, but he couldn't imagine what kind of trouble he would find in the future with the excuses he made at will.

Soon, the computer was started, Xiao Yuan called up the gadget he wrote again, and scanned the poisoned hard disk again, the computer hard disk in the school computer room was very small, and there was not much software installed in it, plus when Xiao Yuan wrote this tool, the scanning algorithm used was very exquisite, so, the scanning speed was very fast, in less than ten minutes, the entire hard disk was scanned, and the anti-virus work was also over.

The next work is purely repetitive work, this work, Xiao Yuan handed over to Tang Xinyu to do, and he himself has more important work to do, that is, to repair the BIOS that were damaged by the CIH virus.

Tang Xinyu followed Xiao Yuan's instructions, repairing the poisoned hard disk while observing Xiao Yuan's next moves.

Xiao Yuan found a student machine that was not infected, copied the BIOS repair tool he had written before, and extracted the BIOS program of the intact student machine after running, and then pried off the BIOS chip on the motherboard without shutting down.

Tang Xinyu, who has been observing carefully, suddenly raised his throat, Xiao Yuan's move in his opinion, can be described as extremely dangerous, you know, before the USB interface standard came out, all computer textbooks were written with such a serious warning: it is strictly forbidden to hot-swap computer hardware.

"Xiao Yuan, what are you going to do?" Tang Xinyu exclaimed.

"Repair the BIOS of the poisoned machine, rest assured, if you are careful, the chip will not burn." Xiao Yuan knew what Tang Xinyu was worried about, so he explained that since all the student models were exactly the same, he could do this, otherwise, he would have to find another way.

Xiao Yuan put the chip on the computer desk, found a damaged student machine, pried off the BIOS chip on the motherboard that was damaged by the CIH virus, plugged it into the open computer motherboard just now, and then used the tool he had just written to flash the previously extracted BIOS program into the damaged chip.

After brushing, Xiao Yuan unplugged the chip again, plugged it back into the previous computer, and then took a disinfected hard disk and installed it, turned on the power, turned on the machine, and with a bang, the machine was powered on smoothly, and the blue sky and white clouds of windows98 appeared on the screen.

Tang Xinyu breathed a sigh of relief, and secretly wiped the cold sweat on his head, Xiao Yuan's hot plugging and repairing BIOS just now made him feel frightened, and it was only then that he put his mind at ease.

"You're amazing." Tang Xinyu praised it from the bottom of his heart.

Xiao Yuan smiled slightly, didn't say anything, and didn't show joy because of Tang Xinyu's praise, but continued to work on his computer repair.

Seeing Xiao Yuan's praise of himself unmoved, his face was calm, Tang Xinyu felt speechless for a while, and said in his heart This guy is really a freak, but people with skills are weird, and it is normal, it seems that he will have more contact with him in the future, and he can learn a trick and a half, and he will not always be despised by his sister, and now, he has completely lost the consciousness of a teacher, and in fact, he has just graduated from junior college, not a few years older than Xiao Yuan and them.

There are a total of eight machines in the computer room that were damaged by the CIH virus, Xiao Yuan acted quickly, and it didn't take much effort to repair all the chips, Tang Xinyu also repaired all the hard disks, and the two of them worked together to install all the machines and boot them up, no problem, so far, all the computers damaged by the CIH virus have been repaired, and Xiao Yuan has been hit with the CIH virus immune patch.

"Xiao Yuan, I'll invite you to dinner at noon today, let's have a good chat." Tang Xinyu looked at his watch, it was almost noon, so he took the initiative to invite him, since he had the idea of learning from Xiao Yuan, he put down the teacher's shelf and called Xiao Yuan a brother.

"No, I have something to do when I get home at noon." Where would Xiao Yuan be in the mood to eat with Tang Xinyu, he was now full of thoughts about his rebirth, so he refused Tang Xinyu's invitation without hesitation.

"Okay then." Tang Xinyu saw Xiao Yuan's refusal, and he didn't insist.

"Teacher, it's not too early, I'll go first." Xiao Yuan put away his things, put them in his bag, and said.

"Okay, let's go out together." Tang Xinyu said.

After the two walked out of the computer room, they separated, and at this time they had not yet finished school, because the school was completely closed, Xiao Yuan couldn't get out of the school gate if he wanted to go home, so he had to go back to the classroom first.

"That's, reborn, I'm not dreaming, hehe." Walking in the familiar and unfamiliar campus, Xiao Yuan smiled bitterly, with some emotion in his heart, and some trance, as if he was in a dream.
