As soon as Liu Xiao heard this, she knew that something was wrong, and sure enough, Zhang Xiaohua was furious, and after that, she would make a phone call every ten minutes or so, called to report the situation, but in fact, it was to vent her dissatisfaction. made Liu Xiao very depressed, he couldn't do anything, analyzed the information, and just looked at the beginning, the phone rang, and he couldn't answer it.

In the end, Liu Xiao completely collapsed, "Grandma, please, it will work if you stop!"

"Am I helping you work, okay?" Zhang Xiaohua played a scoundrel.

Liu Xiao couldn't help it, gritted his teeth, "Okay, okay, you can come, but just watch, don't harass me to work." ”

Liu Xiao didn't finish speaking, Zhang Xiaohua had already called over there and hung up the phone, but in half an hour, Zhang Xiaohua hugged her laptop computer and killed Liu Xiao's room.

Liu Xiao helped her set up the computer and connected the network cable, "Okay, you are guarding the forum, I will analyze the data, remember not to harass me, otherwise I will kick you out." ”

"Anla, An!" Zhang Xiaohua waved her hand and pulled out a book from her bag, "I've been prepared for a long time, I'll read my book, and I won't disturb you!"

Liu Xiao took a look, a little surprised, this girl didn't know which tendon was wrong, she actually took a copy of "Computer Network Technology", and when she looked at the page, she knew that she had borrowed it from the school library. Liu Xiao's second monk was puzzled, wondering if this girl was stupid, how to look at this kind of book, Liu Xiao sat back in front of his computer with a puzzled face, glanced at it from time to time, and found that Zhang Xiaohua read it quite seriously, and made a note from time to time.

"Hallucination, it must be an illusion!" Liu Xiao secretly reminded himself in his heart, took a few deep breaths, and then shifted his mind to analyzing the data.

For two or three days in a row, Zhang Xiaohua came to Liu Xiao's room with a computer in the morning, and went home with the computer in the evening. Zhang Chunsheng was not at ease, and asked the waiter of the hotel to go to the "surprise inspection" under various guises, and the result was still the same.

Zhang Chunsheng was completely confused at this time, I don't know what tricks these two are doing, it seems unrealistic to say that there is nothing between them, the two stay in the same room all day and don't come out, who can guarantee that something will not happen? But if there is something between them, it seems that they are also chasing after the wind and shadows, and they have not found anything, so why did they stay in the same room all day and why?

Zhang Chunsheng thought about it, he didn't understand, he didn't feel at ease sitting in the office, he was just this daughter, and he was raised by himself, this was his hope, he regarded Zhang Xiaohua as more important than everything, he didn't care if he thought too much, anyway, he didn't want to see anything bad about his daughter.

"No! I have to take care of it!" Zhang Chunsheng stood up, ready to go to Liu Xiao's room in person to remind the young couple.

He has a lot of good feelings for Liu Xiao, but if he wants Zhang Xiaohua and Liu Xiao to develop, he is still a little dissatisfied, at least he thinks that Liu Xiao is not good enough, except for the computer level, Liu Xiao has too much gap with his daughter in any other aspect, in his heart, his daughter is the best girl in the world. She really wants to develop the object, she must be strict with the checks, thousands of choices, and must choose one who is the best in all aspects.

Zhang Chunsheng hadn't left the office door yet, and Zhang Xiaohua came in angrily, "Dad, have you made enough trouble!"

"What am I messing with?" Zhang Chunsheng pretended not to know and played a scoundrel, "Why are you talking to me like that!"

"You let Secretary Xiao Li and the waiter run into our room endlessly, and you still don't let us do things?" Zhang Xiaohua's face turned red with anger.

"No!" Zhang Chunsheng continued to deny, "Secretary Xiao Li and waiter, that's all needed for work!", Zhang Chunsheng finished speaking, and sat back in his chair, "Besides, what can you do? Don't stay in Liu Xiao's room if you have nothing to do in the future, you will affect his work!"

"Who said I can't do things?" Zhang Xiaohua patted Zhang Chunsheng's table, "You are prejudiced against me!"

"It's my bias, it's my bias. Zhang Chunsheng walked out of the desk and sat down on the sofa with a smile, "My daughter is the most capable, right?"

"Then you still do this?" Zhang Xiaohua was still very angry.

"Don't be angry, am I wrong?" Zhang Chunsheng still smiled, "But I'm also for your good! Think about it, the dignified daughter of the head of the Zhang family, if she has nothing to do, she will go to a man's room and stay for a day, how bad the impact is, and now the people in the whole hotel are chewing their tongues, if this is spread outside, how bad it will be for your reputation!"

"Whoever likes to chew it, chew it!" Zhang Xiaohua said hatefully, "It's better to chew their tongues out!"

"I can't say anything, what's the name of that word......" Zhang Chunsheng searched his intestines and thought for a long time, "Yes, everyone is golden, it's that person's words are terrifying, you have to pay attention to the influence!"

"I think you're suspicious!" Zhang Xiaohua glared at her father with wide eyes.

"I have absolutely no doubts!" Zhang Chunsheng patted his chest, "You are also older, what kind of person you make is your freedom." But, as a father, I think I still have an obligation to protect you. You tell me the truth, do you have that meaning with Liu Xiao?"

"Which meaning, which meaning?" Zhang Xiaohua immediately jumped up, "Why are you all so vulgar, is it interesting for the two of you to be together?"

"Bastard!" Zhang Chunsheng also jumped, his face flushed with anger. Secretary Xiao Li at the door was also extremely embarrassed, sitting there stupidly, at a loss, and didn't know what to do.

Zhang's father and daughter didn't let anyone, they were staring at each other with big eyes, Liu Xiao suddenly ran in, very excited, and said: "Xiaohua, go and see, I found it, that guy was finally caught by my tail!"

After speaking, Liu Xiao realized that the atmosphere was a little wrong, and then looked at Secretary Xiao Li's helpless appearance, he realized that he seemed to have come at the wrong time, and scratched his head, "That...... , then I'll go back first. ”

"I'll go too!" Zhang Xiaohua followed and walked to the door.

"Don't be in a hurry, you talk about things first!" Liu Xiao hurriedly waved his hand.

"Let you go, what nonsense!" Zhang Xiaohua squirted at Liu Xiao and pushed him out.

Liu Xiao asked the masters of the anti-virus forum to help him capture the kind of Trojan horse used by Wu Yue Overlord, and many people have caught it in the past two days, Liu Xiao identified them one by one, all of them belonged to Wu Yue Overlord. But just when Zhang Xiaohua went out, someone released another one on the forum, which was just captured, Liu Xiao identified it and found that the address of this Trojan backlink was a completely different new domain name, that is to say, this Trojan horse is very likely to be used by Wu Yue's accomplices. Liu Xiaoxing rushed to call Zhang Xiaohua, but he didn't expect to encounter such an embarrassing situation.

After listening to what Liu Xiao said, Zhang Xiaohua couldn't help nodding, and she didn't know if she understood, but just asked, "Then what are you going to do next?"

"Anti-surveillance, completely control this guy, and see if he is an accomplice of Wu Yue Overlord. If so, we will collect information on his machine to confirm his location, and we must thoroughly check his information during the period. Including his upper three generations and the next three generations, I have to find out. Liu Xiao said cruelly, "In addition, we must continue to capture this Trojan horse and strive to dig out all his accomplices." ”

Zhang Xiaohua let out an "oh", a little excited, "Then do you want to continue to guard the forum?"

"Hold on first! Wait for me to confirm the identity of this guy, if it is really an accomplice of Wu Yue Overlord, then the forum can be withdrawn. Liu Xiao didn't notice that Zhang Xiaohua's mood was a little low.

Zhang Xiaohua returned to her computer, sat in a daze for a while, and suddenly stood up, "I'm in a bad mood today, go back first, and the computer will put you here first." ”

"What's wrong?" Liu Xiao realized that something was wrong with Zhang Xiaohua at this time, and hurriedly asked, "Is something wrong?"

"It's okay, it's just a bad mood!" Zhang Xiaohua said and was about to leave.

"Are you really okay?" Liu Xiao hurriedly got up and chased after him, "If you have something, just say it, it's better to say it, and I can help you!"

"It's all right!" Zhang Xiaohua was very impatient, and as soon as she went out, she "snapped" the door shut, and Liu Xiao in the back was fortunate to be quick to stop, otherwise he would have been clamped. When he chased him out again, Zhang Xiaohua had already entered the elevator and went downstairs.

"What's the matter?" Liu Xiao touched his chin, "It seems that I didn't offend her today, right?" Shaking his head, Liu Xiao hurriedly returned to the room, now that there are some clues, you have to hurry up.

Liu Xiao modified the Trojan of Wu Yue Overlord and changed the address of the backlink to the new domain name captured today, but it turned out that it was also not linked, and the IP address to which the domain name was turned was not online, and Liu Xiao's excitement was immediately reduced by more than half. This IP is also from Sanyang City, it seems to have something to do with Wu Yue Overlord, and he is not online at the moment, is this guy also escaping, or is he just not online for the time being?

Liu Xiao waited for a while, but the Trojan still couldn't be linked, Liu Xiao had to give up waiting, and went to the anti-virus forum to look, no new Trojan was released, Liu Xiao flipped down again, and saw the post that asked him to help analyze the virus sample.

"Oh my God, how did I forget this!" Liu Xiao patted his head, others were busy with their own affairs for a few days, but they forgot all about other people's affairs, Liu Xiao really felt a little sorry for others.

Quickly turned out the virus sample downloaded last time, Liu Xiao put it into the virtual system to run, recorded all the actions after the virus was run, and then sent the record to his real system and began to analyze.

After roughly browsing the records, Liu Xiao knew that the power of this virus was not very powerful, but it was only for the destruction of software and data, and there was no harm to the hardware. The first is that the virus will modify the system file association to ensure that it runs at all times, and it will generate a large number of daemons, so that you can't terminate the operation of the virus, and the biggest destructive force is that the virus will be bundled and merged with all the executable programs in the system, that is, how many executable programs in the system will have as many viruses as there are, which increases the difficulty for users to remove the virus.

However, there are not a few such viruses, not unusual, Liu Xiao analyzed the records of the virus operation again, and found no new discoveries, the virus does not have any backdoor, and there is no way to spread, it seems that this is just a prototype sample of the virus, unless someone deliberately planted it on your machine, otherwise there is no power at all.

Liu Xiao dragged out a file that had been bundled and merged by the virus from the virtual system, and then decompiled the file. Looking at the decompiled code, Liu Xiao was a little puzzled, the code of this virus is very different, it is like water and oil, the user's own program is water, the virus is oil, and the oil is poured into the water, it will be clear up and down;

In such an obvious situation, it is very easy to get rid of the virus. The person who asked Liu Xiao for help on the forum was also an anti-virus master, how could it be such a simple virus and couldn't figure it out, Liu Xiao really couldn't figure it out.

"Could it be that the virus is encrypted?" Liu Xiao hurriedly went to see his decompilation tool, which was made by himself and would automatically decrypt and unshell.

At a glance, Liu Xiao was extremely surprised, the encryption method of this virus turned out to be the encryption method of the Trojan horse of Wufeifan back then, Liu Xiao went to open the Trojan of Wu Yue Overlord again, and found that the Trojan horse was also encrypted, all of which were the same encryption method. It's just that Liu Xiao's tool automatically completed the decryption work, so Liu Xiao didn't notice this problem before.

"No, could it be that this virus is also the work of wufeifan?" Liu Xiao hurriedly looked for the word "wufeifan" in the code of the virus.

Sure enough, the tool pops up a prompt, "Found!", and then automatically locates to the location where Wufeifan was found.

PS：

File association: As a simple example, many people like to watch movies, and you may have noticed that there are many formats of movies, RM format movies should be watched with RealonePlay player, and WMA format should be watched with MediaPlay. If you have a player installed on your machine, when you click on a movie in a certain format, you will find that the system will automatically launch the player that matches it, which is called file association, which is used to associate the file with the program that opened the file. If a file is associated with a virus program, then you run the file at the same time as you run the virus.

You may also have found that after the machine was poisoned, the virus was cleared with antivirus software, but there were many programs and files that could not be opened, this is because although the virus was cleared, the file association was modified by the virus and was not recovered.
