"What should I do then?" Boss Xiong was still calm and looked at Liu Xiao, "Since you can analyze the reason, you should have a way to separate the data!"

Liu Xiao frowned and said, "There is a way! It's just that I have never encountered this situation before, and I haven't tried it, so I ......."

"It's okay! Anyway, the data is already bad, it's still a bad thing, you just go ahead and try." Boss Xiong expressed his attitude, now there is no way for experts at home and abroad, anyway, they are all dead, it is better to let Liu Xiao give it a try.

"Okay, I'll try my best!" Liu Xiao nodded and turned back to the man, "You just said that the database files infected by the virus are not backed up, right?"

"Yes. The man also had a headache, "Otherwise, he wouldn't be so passive!"

"Did the virus only infect this database file?" Liu Xiao continued to ask.

"No, the files on the server are infected!"

Liu Xiao asked, "What about the other documents? Have you also done the work of removing the virus?"

"No, I changed to a new server, so the rest of the files are still there!"

"That's good!" Liu Xiao finally took a breath, "You guys immediately go to that server to get a file, if you want to be infected by a virus, you can have any file!"

"Okay, good!" the man nodded hurriedly, "I'll do it!"

"Don't worry!" Liu Xiao called out to the man, "And the expert you eliminated the virus before is still there, I need to know how he eliminated the virus, and I must know the specific algorithm." ”

"Okay, I'll call that expert too!" After the man finished speaking, seeing that Liu Xiao had no more instructions, he hurried to make arrangements.

Liu Xiao looked back at Boss Xiong, "Boss Xiong, I have to trouble your car to send me on another trip, I have to go home, there is a relatively comprehensive virus database on the computer at home, I need this virus database to make a judgment." ”

"Then let's go!" Boss Xiong didn't say a word, and took the lead in saying: "I'll accompany you personally!"

Liu Xiao got into the car and said a place, and the driver started the car.

"Liu Xiao, you've already seen the damaged file, how likely are you to recover it?" asked Boss Xiong.

"It's more difficult to repair this kind of damaged file, anyway, I'll do my best!" Liu Xiao sighed, "It's like a building, you tear it down and build another one as it is, it's very simple." But if the keel of the building is suddenly removed, it will be very difficult to maintain the building in its original state, and it will cost more than building ten of them. ”

"I understand this!" Boss Xiong became even more worried, and said, "Even if it costs a hundred buildings, this file must be restored, do you understand?

The files to be repaired must be valuable, but Liu Xiao can't think of any file that can be worth a hundred buildings, but he still said: "Mr. Xiong, you don't have to worry too much, according to my experience, as long as the method is right, it shouldn't be a problem to recover data." ”

Boss Xiong was a little relieved, closed his eyes and lay on the backrest, no longer speaking.

Liu Xiao went home to get his computer, and returned to the white courtyard with Boss Xiong again, the person was already waiting there, and there was an extra person in his thirties in the room.

Seeing Liu Xiao coming in with the computer on his back, the man hurriedly stepped forward to take the computer and said, "We have taken everything you want, this is the expert who was responsible for removing the virus before." ”

The man in his thirties stepped forward and nodded slightly, "Wei Gang!"

Liu Xiao hesitated, this name was very familiar to him. Wei Gang, a master among the masters in the anti-virus world, is nicknamed "Feng Qingyang", everyone says that Wei Gang is proficient in the anti-virus "Dugu Nine Swords", and any virus in his hands is considered to be at the end, and he can easily uproot the virus. Liu Xiao hurriedly stretched out his hand, "Senior Wei, I have admired the name for a long time!"

Wei Gang smiled indifferently, "Seniors don't dare to be, I just entered the industry a few days earlier than you, our industry relies on strength, technology, and qualifications." Hehe, no, I stabbed Lou Zi and you have to clean it up today. ”

"It's my honor! I'll do my best!" Liu Xiao gritted his teeth, "I see it as a challenge." ”

Wei Gang heard the meaning of Liu Xiao's words, and patted Liu Xiao's shoulder with a smile, "Okay! He dragged Liu Xiao to the computer and took out a USB flash drive, "This is my research and analysis of this virus, as well as the algorithm and tools I used to remove the virus last time, if you still have anything unclear, just ask me." ”

"Thank you, senior!" Liu Xiao took the USB flash drive, turned to the man and asked for his computer to open it, "What about the virus-infected files you picked up?"

The man also hurriedly handed over another USB flash drive, "Here." ”

Liu Xiao first copied the virus-infected files to his computer, but as soon as he copied it, the alarm on his computer began to ring, prompting that a virus had been found!

"Huh?" Liu Xiao was a little surprised, the virus turned out to be already in his own virus database, so this virus should not be unusual, why did Wei Gang carelessly eliminate it.

Wei Gang also saw the alarm, surrounded him, and said, "What's wrong?"

Liu Xiao clicked on the report of the alarm, glanced at it, looked back at Wei Gang, and frowned: "I have seen this virus before!"

"Seen?" Wei Gang was surprised, "When have you seen it?" It's really strange why I don't have a virus in my database. Wei Gang was shocked, in terms of the capacity of the virus database, he is definitely the most complete in China, why did he just miss this virus.

Liu Xiao nodded, "I did see it, but ......"

"But what?" Wei Gang hurriedly asked.

"I mean, the current virus is a little different from what I've seen before, it should be a variant!" Liu Xiao's brows furrowed together, he also couldn't understand that this virus was obviously thrown to Liao's by himself, and he also took precautions, why could it be infected outside of Liao's?

Liu Xiao hurriedly used the tool to open the virus-infected file, he had to confirm it, although the alarm showed that this was a modified Wufeifan virus, and there were traces of his own modification, but he felt that this would definitely not be the variant he modified.

Wei Gang next to him was a little anxious, "Then where did you see this virus last time?"

"Have you heard of the Terminator Forum?" asked Liu Xiao. The Terminator forum he is talking about is the forum of folk anti-virus enthusiasts that he often goes to.

Wei Gang nodded, "Of course I know this, but I haven't been there for a long time, and several masters there in the past were recruited by major companies later, and now there are no masters there." ”

"More than a month ago, the original sample of the virus was published on the Terminator forum, and some people announced the method of eradication, and issued an early warning that the variant of the virus would soon hit the network. When Liu Xiao said this, he was a little proud in his heart, everything was expected by him.

Wei Gang was stunned for a moment, and then sighed, "It seems that the anti-virus industry is full of talents, and the rising stars really can't be ignored, if I can be a little more modest and cautious, I won't plant this heel." After speaking, he looked at Liu Xiao, "Then you should know the way to get rid of this virus, right?"

Liu Xiao nodded: "I know, I know, but I have to analyze it again, now this is a variant of the virus, and the method of deletion will definitely change slightly." Liu Xiao paused after speaking, and glanced at Wei Gang with slanted eyes, "I heard that the shell of this virus is difficult to take off, it took someone more than a month to successfully take off its shell before, and Senior Wei can do it in such a short time, you deserve the words "superb technology." ”

"Where, where!" Wei Gang waved his hand and said, "I'm not afraid of your jokes, I encountered the shell of this virus two years ago, and it was used on a Trojan horse program at that time." At that time, after I caught the Trojan horse, I couldn't get rid of the shell, and then I went to the Terminator forum to post for help, but unfortunately there was no follow-up, and it took me two months to take off the shell. I remember very well that the author of that Trojan at that time was called wufeifan. ”

Liu Xiao's eyes straightened, the world is so small, who would have thought that a master like Wei Gang would wear a vest to the forum to ask for help, and the object of help would be himself, who was still very vegetable at the time, and what Liu Xiao didn't expect was that he would be able to see the owner of the vest two years later. If Wei Gang knew about these things, it is estimated that he would have broken his glasses, but Wei Gang was able to say this calmly, which made Liu Xiao admire, which was much greater than the courage of Long Izumo and Evil Sword that he had seen. Liu Xiao didn't make this matter clear, and asked, "Does Senior Wei know who this wufeifan is?"

Wei Gang shook his head, "I've also been tracking for two years, but I haven't gotten any information about this wufeifan." ”

Liu Xiao let out an "oh", lay down in front of the computer, and concentrated on studying the file.

The variant of this virus is indeed the one modified by Liu Xiao, and its transmission method in the LAN is unique, which is the method that Liu Xiao improved from stepping on the snow without a trace. But this variant has obviously been modified, and someone has added a way to spread it outside of Liao's, allowing it to escape from Liao's, greatly increasing the concealment of the virus, and most importantly, adding new features. Liu Xiao ran it in a virtual system, and found that the virus opened a backdoor in the machine, and the virus constantly listened to this backdoor, waiting for its master's command to arrive, and once the command arrived, the virus would instantly turn a good computer into a broiler.

"Someone is using this virus to cultivate a botnet!" Wei Gang reminded from the side.

Liu Xiao nodded, of course he knew that if the virus was infected unlimitedly, there would be many computers that would be tricked, if the virus didn't attack, these computers would look the same as normal computers on the surface, but once the owner of the virus issued an order, all the computers that were tricked would be controlled and used in an instant, this is the so-called "botnet".

Liu Xiao doesn't care about the purpose of the owner of the virus, what he cares about is who modified this variant, it stands to reason that only the evil sword can access this virus, but the evil sword has no reason or motive to cultivate a botnet; and the name of the author in the virus variant has not been modified, it is still wufeifan, if this is modified by wufeifan, the motive is there, but how did he know that this virus broke out in Liao's corporate network?

"Could it be ......" Liu Xiao had a bold idea in his heart, if the evil sword = wufeifan......

"Have you thought of a way to get rid of the virus?" Wei Gang asked out loud when he saw Liu Xiao standing there for a long time without any reaction.

"Oh?" Liu Xiao came back to his senses, was stunned for a moment, and said, "You can get rid of it, I'll try it!" After Liu Xiao finished speaking, he rummaged through his computer and found a tool, which was the virus cleaning tool he had prepared for Liao's before, he originally planned to be embarrassed by the evil sword, so he put this tool on Liao's, but what he didn't expect was that he was quickly driven out of Zhang's by Zhang Chunsheng, and when he arrived in Haicheng, he forgot about it.

At that moment, Liu Xiao ran this removal tool to remove the virus code from the virus-infected file.

"Senior Wei, take a look!" Liu Xiao pointed to the repaired file, "You check and check to see if it has been eliminated?"

Wei Gang stepped forward and just glanced at it slightly, and said, "It's completely fixed!", but he was suspicious in his heart, this Liu Xiao just said that the method of elimination would be different, and now he directly pulled out the tool to remove the virus, could he still be unpredictable, and the tool was prepared before coming?

Liu Xiao didn't notice his negligence just now, and said with a smile: "That's good, it seems that there is great hope for data recovery!"

When Mr. Xiong behind him heard this, he suddenly relaxed a lot, and his locked brows couldn't help but stretch, waiting excitedly for Liu Xiao's next move.

Liu Xiao made a backup of the damaged data, one of which he wanted to copy to his machine, which was more secure, but as soon as he copied it, he was prompted that he had no permission.

The man stepped forward and said, "I'm sorry, but these data are important and can't be passed on, so ......"

Liu Xiao expressed his understanding, put the backup away, and then copied his own elimination tool to remove the residual virus code in the database, and then he opened the database and looked at it, and said happily: "Success!"

After saying that, he directly took action, separated the records of the last day in the database, made a database file, and then said to the man: "Okay, you take this file, and then merge it with your previous database backup, there should be no problem." ”

The man was very excited, quickly copied it, took it away and tried it, and turned around to thank Liu Xiao again and again.

"I have a question!" Wei Gang interrupted everyone and said coldly: "I want to know, what is the reason for my previous culling failure, and please give me advice!" Although Wei Gang asked why he failed, what he wanted to know was why Liu Xiao was able to eliminate the virus so easily, and even Liu Xiao didn't even glance at his previous culling algorithm.

This had to make Wei Gang suspicious, and he couldn't explain why Liu Xiao would prepare a special killing tool to remove the virus in advance.
