It may be that Liu Xiao's encryption algorithm really stumped ufeifan, or ufeifan knew that the general trend was gone and decided to stop, anyway, he never released a new virus.

Two hours later, the servers of the antivirus software vendor were restored to normal, and the update function of the virus database was also returned to normal.

At this point, the virus crisis created by ufeifan has been completely controlled.

"Damn!"

When Liu Xiao logged in to the Terminator forum again, he couldn't help but curse, almost everyone on the forum was talking about the collective action of the antivirus software vendors, with mixed reviews, but there were obviously more praises than criticisms, but what made Liu Xiao depressed was that no one noticed the virus protection software he designed. Liu Xiao wondered, the two software were downloaded at the same time, and he also put the "Kuaiyun Studio" in an obvious position in the software, how could these people not even ask, didn't they see it?

"Grandma's!" Liu Xiao hated in his heart, it seemed that his plan to take the opportunity to enhance the reputation of the studio had failed again, this was the second time, it was not as good as the first time, at least last time, someone jumped out and scolded himself for dragging the dragon's tail to ascend to heaven, this time people didn't even have the interest in scolding.

Liu Xiao looked at the new version of the protection software that he had just worked on for several hours, and he didn't know whether he should continue to put this software on the forum for a while.

After thinking about it, Liu Xiao finally decided to release it, but he had to change the form of release, Liu Xiao sat in front of the computer and crackled for a long time, sorting out the causes and consequences of this virus incident, the ins and outs of the virus incident into a document, and finally he read it himself, and couldn't help but admire himself a little, "Nervous! Wonderful!

Liu Xiao looked at his work with satisfaction, he was going to send this out, first, it can attract everyone's attention, everyone knows about the virus crisis, but what they know is only some superficial fragmented things, and they must not know the wonderful stories inside; second, Liu Xiao wants to make everyone face up to the importance of defending against unknown viruses through this incident; third, Liu Xiao can take advantage of the situation to release his new version of the protection software, so that no one will say that he is dragging the dragon's tail to the sky.

After checking, there were indeed no mistakes, Liu Xiao put the article out, and at the end he didn't forget to write the words "produced by Kuaiyun Studio" at the end of the article.

"Ahhh!!h

When he came back to the computer again, he almost didn't startle him, and the post he had just made was instantly topped to more than twenty pages, which had never happened in the Terminator forum.

"It's not going to scold me again!" Liu Xiao suddenly felt in his heart, took a deep breath, he clicked on his post, and at the top of the top were those antivirus software people, now they have set up a special area in the Terminator Forum, no way, the influence of the Terminator Forum is not what it used to be, some small security companies and foreign antivirus software have set up a special area here, if they don't set it up, it will be equivalent to giving this position to others, they will not be so stupid.

"Whew~" Liu Xiao let out a sigh of relief, fortunately, he didn't scold himself. How much effort Liu Xiao made in this reversal, those antivirus software vendors knew best, so as soon as Liu Xiao posted, they quickly pushed it up to show their support.

Liu Xiao looked down again, and his heart became happy, it seemed that he really used this trick correctly, and the emotions of these people in the forum were hung up by his own posts.

The power of truth is so strong, everyone knows that the virus is spreading, but they don't know who made the virus, why he made it, how the virus spreads, how much damage it can cause? Why all the antivirus software fails in the face of the virus, what measures do the antivirus software vendors take, and how do they finally reverse it and eliminate the virus?

Liu Xiao's post completely solved all the doubts in everyone's hearts, the forum was lively for a while, all talking about this matter, if everyone was just surprised that the antivirus software would be killed by the virus, then now it is shocking. No one would have thought that there would be such a powerful virus group on the Internet, they have achieved collectivization from creating viruses to spreading viruses, and once they launch an attack, they will be in step with each other, with clear goals, and can output the maximum attack capability in an instant, so that antivirus software vendors are helpless.

Everyone almost unanimously agreed with Liu Xiao's point of view, antivirus software must be able to predict and plan unknown viruses, otherwise such incidents will happen again.

Liu Xiao was very excited, and pinched his fingers loudly, he didn't expect his post to cause such a big response, it seems that it is time to release the protection software.

After walking around the room twice, Liu Xiao temporarily changed his attention, and he decided to write another article, not because he was addicted to writing, but because he was too excited now, and the support of many people on the forum made him feel that he had to express something. So he decided to write another article to introduce his ideas and principles for designing virus protection software, and then take the source code of this protection software to the Terminator forum to make it public, so that all peers can participate, develop and improve together. In this article, Liu Xiao put forward an anti-virus concept for the first time: active defense.

Just like Torvalds made the Linux operating system, he just put the core source code of the Linux system he designed on the Internet, and then under the collective creation of so many people, Linux was born.

"Alas......" Liu Xiao sighed and laughed at himself: "Torvalds released the source code, and the name was used to name the asteroid, and he will publish the source code now, I don't know if there will be this treatment!"

After Liu Xiao finished laughing, he posted the post. Wait for a few minutes,Liu Xiao refreshed,There are still so many people who pay attention this time,But there are obviously fewer people who like the post,The current Terminator Forum is dominated by people who watch the excitement,There are only a few experts who can understand technical information,But these insiders have affirmed Liu Xiao's spirit of sharing,And said that this software will continue to improve。

Seeing this, the administrator of the Terminator forum set aside a special area for these technical experts to continue to develop this set of virus protection software.

Liu Xiao flipped through the post, and didn't see the names of those antivirus software vendors, Liu Xiao smiled helplessly, it's strange to have it, if this protection software of his own is really improved by all the masters, then these antivirus software vendors don't have to do business, they are smashing other people's jobs, how can people support it.

It's all done, Liu Xiao is really a little unable to hold on at this time, he is going to take a break, anyway, even if ufeifan releases the virus again, he is not afraid, his own protection is specially made for him, now it is not only to prevent ufeifan's new virus, it can also kill all the viruses before ufeifan, even other viruses, Liu Xiao's protection software also has a good ability to prevent and kill.

"Take a look at it one last time, and go to sleep if it's okay!" Liu Xiao refreshed the forum again with this mentality, and found that a new post appeared on it, the title of the post: "Questioning the feasibility of active defensive antivirus software!", and the ID of the person who posted it is the "future terminator" that Liu Xiao is no longer familiar with!

"Damn!" Liu Xiao suddenly fell asleep, "Ufeifan seems to want to continue playing!"

Clicking on the post, Liu Xiao quickly browsed it, ufeifan did not refute the details of Liu Xiao's design ideas in the article, but reminded Liu Xiao, "You remember all the characteristics of the virus, infectiousness, illegality, concealment, latent and destructive, you judge whether a program is a virus based on these characteristics, but you just forget the last characteristic of the virus, that is, unpredictability!"

ufeifan's meaning is very clear, it is precisely because of the unpredictability of the virus, it will bring many new characteristics to the virus, if you just use the characteristics of these viruses defined in the textbook to design software to defend against unknown viruses, it is equivalent to a tree seeking fish, and in the end it can only be a fool's dream.

At the end of the post, Ufeifan challenged again, "I will use facts to prove that my opinion is correct, and I will also use facts to tell you: you are too naïve!"

"Cut!" Liu Xiao raised his middle finger at the computer, "Come if you want to come, Lao Tzu won't be afraid of you!" Liu Xiao didn't take this challenge of ufeifan in his eyes at all, if you can prove your point of view with facts, then I can also use your failure to prove my point of view!

"Let's see!" Liu Xiao snorted, got up and turned off the computer, and fell down on the bed to rest.

I don't know how long I slept, anyway, Liu Xiao felt that he had just closed his eyes, and he was just a little confused, so the phone called, Liu Xiao really didn't want to get up, turned over and continued to sleep, but the phone kept ringing!

"Oh my God!" Liu Xiao screamed in extreme pain, stretched out a hand and touched the bed, and finally found the phone, and when he came to his eyes, he took a look, it was Wei Gang's! Liu Xiao then cheered up and sat up.

"Hey, Senior Wei, is there something wrong?" Liu Xiao asked, if Wei Gang said "It's okay", it is estimated that he would be able to lie down immediately and continue to sleep.

"Well, something's wrong!" Wei Gang didn't fulfill Liu Xiao's wish, but asked, "What are you doing, why don't you answer the phone for half a day!"

"Oh......" Liu Xiao was still confused, "What's the matter?"

"Ufeifan has released a new virus, this time specifically for you!" Wei Gang said.

"Huh?" Liu Xiao couldn't react a little, "When did it happen?"

"More than an hour ago!" Wei Gang laughed, "Thanks to your kid who instigated him on the forum and let him release this new virus, otherwise we really can't determine the source of that kid's virus! It's really amazing, I don't know how many years this kid has been in business, there will be such a huge virus spread channel, fortunately it was discovered early, if this kid is allowed to develop for another two years, it is estimated that it will become the first major harm on the Internet. ”

Liu Xiao finally came to his senses, but he was a little confused, he didn't seem to be instigating ufeifan, it was obviously ufeifan who was provoking himself, "Senior Wei, tell me in detail, what's going on!"

"Didn't you just make a post saying that you could block an unknown virus!" Wei Gang asked rhetorically, and then continued: "Then ufeifan was not convinced, and a new virus was released, which can completely escape all judgments about the characteristics of the virus, this kid wants to show off his skills, but he didn't expect to completely expose his old bottom." Wei Gang laughed again when he said this, "It's so interesting, this kid's virus is actually ingenious, has the function of blackmail, and has a special account to collect money, which makes the people of the Internet supervisor pull their tails, and now they are trying their best to track down the true identity of this kid." ”

"Tell me in detail!" Liu Xiao was a little anxious, "What kind of blackmail method is it!"

"I'll pass that virus to you right now!" Wei Gang still couldn't hold back his laughter, "You'll understand after reading it!" By the way, since it's against you this time, then you can clean up this matter, and you will be responsible for getting rid of this virus!"

It seems that Wei Gang is going to completely give up the competition with Liu Xiao, and it is not interesting to fight back and forth, if he really competes with ufeifan one-on-one, it is estimated that he and Liu Xiao are not his opponents, not to lose in technology, but ufeifan's ability to control the virus is really terrifying.

After hanging up the phone, Liu Xiao saw the time clearly, it turned out that he had been asleep for nearly six hours, Liu Xiao scratched his head, why did he feel like he hadn't slept yet.

After a few pats on his face, Liu Xiao got up and turned on the computer, opened the mailbox, and Wei Gang's letter had already been sent.

Liu Xiao put the virus in the attachment into the virtual system to run, according to the usual habits, a minute later, he took out the record report of the monitor from the virtual system, opened it and looked, Liu Xiao was stupid, there was no abnormal record.

Liu Xiao began to sweat, could it be that this kid ufeifan has really become a fairy, and there is no abnormal behavior after the virus runs, is this also called a virus?

Two minutes later, Liu Xiao took out the report again, and there was still no record of abnormal behavior. Three minutes later, no! Five minutes later, no! Ten minutes later, it's still blank!

"Damn!" Liu Xiao slapped the table, "Could it be that the monitor of this dog day is broken, or is there something wrong with your own virtual system?"

Liu Xiao restarted the virtual system, confirmed that the system was not abnormal, and he was about to run the virus again, only to find that there seemed to be an additional icon on the desktop of the virtual system.

"What is this?"

Liu Xiao clicked on the icon, and a window popped up: "Because you are using a pirated operating system, the system has now destroyed all your document files, report files and database files." If you want to recover such documents, please remit RMB 200 to the bank account xxxxxxxxxxxx, and then send the remittance serial number to the mobile phone 13923456789, you will get a genuine system activation code, please enter the obtained activation code into the activation box below the program, and your documents will be restored. Thank you for your cooperation, please support the genuine version!"

"Damn!" Liu Xiao was a little devastated, this ufeifan never forgot to use the virus to make money, and this time was no exception, this kind of trick was used.

Liu Xiao hurriedly flipped through the virtual system, and sure enough, several ORD files he had placed on it had disappeared, which was by no means as simple as setting hidden attributes, but it was really gone!

"Day!" Liu Xiao scratched his head, something fucking weird, how did this document disappear, why didn't the monitor react at all.

Liu Xiao turned on his monitor and re-set the monitor, this time he wanted to record all the actions of the virus, instead of only recording abnormal behaviors before. If there is no record this time, then Liu Xiao will really collapse.

After double-clicking and running the virus file again, Liu Xiao waited patiently for a long time before taking out the record report from the monitor. This time there is a record, but there is only one record, Liu Xiao looked, after the virus run, did not change any settings of the system, did not destroy any functions of the system, just issued an instruction with the user's identity: search all the document files, report files and database files on the hard disk.

Liu Xiao understood a little, it must be a virus that hid the searched files, and then used it to blackmail computer users, the so-called "because you used a pirated operating system", it is simply an excuse, this is playing psychological warfare with computer users.

There are no important files on Liu Xiao's virtual system, but this virus does not only infect Liu Xiao's computer, if the virus infects the computer of a company that stores important information, then let alone 200 yuan, it is 20,000 yuan, or even more, you have to pay obediently. This ufeifan is really making money!

But where exactly did the virus hide those files? There was no record on the monitor, because all the documents and files on Liu Xiao's virtual system had been hidden during the first run of the virus, and this time the virus did not search for the document files, so naturally there was no object to store.

Liu Xiao was so depressed that he had to create a new document file on the virtual system, with nothing in it, and then ran the virus again.

Wait for a while,Take out the report of the monitor and look at it,Liu Xiao quickly switched to a hidden directory on the virtual system,It turned out,All the lost files are here,It's just encrypted,It's already unrecognizable after opening,If you want to recover the original real data,You have to buy ufeifan's what"genuine system activation code"。
