Xia Chen saw that the family was well guarded by Huzi, so he didn't stay long, and was ready to go back, after all, his parents were not at ease in the hospital, Huzi asked some uncle's condition, and also wanted to see his uncle, but Xia Chen's family went, and there was no one to take care of it at home, so he could only help Xia Chen take care of the family, Xia Chen promised Huzi that he would take Huzi to pick up when his uncle was discharged from the hospital.

When Xia Chen and the others returned to the city, it was already more than nine o'clock, and the mother was still in the hospital to accompany the wife, because she promised Meng Jia to help solve the system problem, Xia Chen and his parents said that they would come back later, and when the parents heard that Xia Chen helped Meng Jia deal with things, the two elders directly drove Xia Chen out of the ward, and said, solve it well, let Xia Chen rest assured at night, Xia Chen wanted Xiaomei to accompany her parents in the hospital, but Xiaomei said that she wanted to learn hacking skills, and pestered Xia Chen to take herself with her.

Xia Chen couldn't stand his sister's soft grinding and hard bubbles, so he had to take Xiaomei and Meng Jia to Meng Jia's company, Meng Jia's company in Shuipan City Square, a modern office building, about half an hour's drive from the hospital, when Xia Chen and others drove to the company, there were only a few sporadic room lights in the whole building still on. Meng Jia led Xia Chen to take the elevator to the eleventh floor, Xiaomei seemed familiar with the road, Meng Jia took out the key to open the company's glass door, and several people walked to the general manager's office, after Meng Jia turned on the light, Xia Chen found that this office was decorated in a modern style, with large floor-to-ceiling windows and shutters hanging on a glass wall in the office area. The whole space seems calm and has a hint of youthful vitality, and occasionally a few small objects embellish the vitality of the owner of the room.

Meng Jia sat down at the desk, opened the laptop on the table, and said to Xia Chen: "My computer is connected to the host of the monitoring room, do you watch it on this computer or go to the monitoring room to watch."

"I'll take a look at your system Trojan on the computer first, you can show me the system with the virus first," said Meng Jia's position, Meng Jia got up and walked to the position of the safe, opened the safe and took out a mobile hard disk from it, Xia Chen walked directly to Meng Jia's position and sat down, Xiaomei also came over curiously. Xia Chen took the hard disk that Meng Jia took and plugged it into the computer, and did not turn on the hard disk immediately, but popped up a text box on the computer, and Xia Chen crackled on the keyboard towards the text. Lines of fast code scrolled up, fingers flew, Meng Jia and Xiaomei on the side opened their mouths in surprise, Meng Jia thought that the computer level was okay, and the speed of writing code was quite fast, but compared to Xia Chenlai, it was simply a primary school level.

Before Meng Jia and Xiaomei came out of their surprise, Xia Chen made a car enter, stopped the code input, and a red box popped up on the computer flashing, which said big OK, Xia Chen exited the code input and clicked to view the hard disk information, when the hard disk was opened, the rows of codes were scrolling rapidly, and finally a piece of code showed an alarm sign that kept flashing, Xia Chen was busy with the computer for a while, knowing that the word OK was displayed again, Xia Chen exited the program.

Xia Chen picked up a bottle of water on the table and unscrewed it and took a few sips, and said to Meng Jia, "The system Trojan has been cleared, and I can be sure that the Trojan horse was implanted through your company's internal network, and at this time, the implanted Trojan computer IP and the implantation time," Xia Chen pointed to a line of IP and said to Meng Jia. "Now you just need to find this computer to know who planted the Trojan."

Meng Jia hasn't come over from the shock yet, the Trojan horse that the company has worked hard for several months has not been cleared, and it was done in less than half an hour, Nima, did I meet a fake programmer. Meng Jia was no longer interested in who planted the Trojan horse, and was curious about how Xia Chen used to remove the Trojan horse.

"How did you do it, you have to know that just for this Trojan horse, the company has been busy up and down for several months and has not been able to solve it, and you have solved it so easily, I have begun to doubt my life," Meng Jia said with a feeling of being hit hard, I am also a top student of a prestigious school, and this kind of blow is a procedure for suspecting whether I am a diploma leave.

"This kind of Trojan horse is actually the most powerful part of it is transplanting and copying, haven't you noticed, I didn't go in and crack it immediately at the beginning, but first set up a firewall on your computer to prevent the Trojan from entering your computer, to put it bluntly, this kind of Trojan will be copied to your computer when you crack it, when you don't set up the firewall of the computer itself, the Trojan horse will copy back and forth between your computer and the implanted system, so only blocking the retreat of the Trojan horse is eradicated at one time," Xia Chen explained.

"Old driver, please bring" Meng Jia said naughtily.

Xia Chen smiled slightly, "Do the right thing, now find this computer first, find the video evidence, who implanted it, and do you have a computer registration manual in your company?"

"No, there have been no accidents since the company was established, and I didn't expect this to happen, so I didn't register the computer. Meng Jia stuck out her tongue and said.

"Then let's do it, I'll now remotely open the computer with the Trojan horse from your computer through IP to see which one, but don't move and we'll check the surveillance video after turning it on," Xia Chen operated on the computer again, and in less than two minutes, a string of numbers and letters jumped on the computer screen.

"What's going on, brother," Xiaomei asked curiously.

"At this time, the other party's computer has set up a boot anti-theft password, and I am cracking it," as a string of letters and numbers hovered over the computer desktop, Xia Chen said: "Okay, now I'll go and see which location the computer is." Speaking of getting up and walking towards the office area, but the three of them turned around and didn't find another computer turned on, Xia Chen asked, "Does the company have any other computers besides the office area?"

"There are three other places, one is the deputy general office, the other is the finance department, and the other is the monitoring room," Meng Jia said.

"Then let's go to these places now," Xia Chen said.

Meng Jia took Xia Chen and Xiaomei to the deputy general office, the door was locked, Xia Chen saw the black inside through the glass wall, turned around and walked to the financial room, the financial room was separated by a physical wall, and there was no window on one side of the office area, Xia Chen asked Meng Jia if he had a spare key, Meng Jia said yes, but he couldn't find it, and he didn't know where to put it, Xia Chen shook his head helplessly, saying that he was used to this person who was lost and grinned. Xia Chen found a paper clip on a desk in the office, straightened it with his hand and stuffed it into the keyhole of the financial room, and the door of the financial room was opened in three clicks and two clicks.
