The next day, in military theory class.

Don't Chang'an passed a note to Su Xiao.

It reads: "After school, come with me and study yesterday's events." ”

Su Xiao glanced at it, and then nodded lightly at Bie Chang'an.

Although he agreed, he still didn't agree with Chang'an's idea.

……

Looking at today's Internet market, how many companies are willing to pay for free killing?

Jinshan Ruixing?

The two major soft-killing giants in the industry do not have this kind of open and free boldness.

Gratis?

This is nothing short of a suicidal move!

Laborious and unflattering.

Costs aside, but you should at least make a profit, right?

Otherwise, what do you ask for?

What kind of medicine is sold in Don't Chang'an's gourd, he doesn't even have the courage to guess!

For the thrill?

For fun?

In Su Xiao's impression, Don't Chang'an don't look like that impetuous person.

But this time, why the impulsive?

……

Su Xiao's worries are not unreasonable.

Perhaps, in his opinion, there is no future and no development for free killing.

But he would not have thought that in the near future, it was this kind of suicidal marketing that allowed a killer software called 360 to enter thousands of households and become the leader of domestic antivirus software.

The current status quo of the Internet is turbid all over the world, and everyone is drunk.

The ever-changing market, not to mention Su Xiao, is unpredictable even for veterans of some large companies.

They were all "drunk".

But don't Chang'an is "awake".

……

After school, Don't Chang'an called the dog to follow Su Xiao, and the three of them went to the rented house together.

When debugging the computer, Su Xiao asked, "Third brother, how much did you spend on these two computers?"

Bei Changan replied while connecting the network cable to the computer: "It's all 15,000, and I bought some miscellaneous things, which cost about 20,000 yuan in total." ”

"Twenty thousand?"

Don't Changan nodded and asked, "Well, what's the matter?"

"It's not expensive, but ...... Where did you get all this money?"

After a while, Bei Changan picked up the milk on the table and said with a smile: "Earned." ”

Su Xiao let out an "oh" and stopped talking, he found that he couldn't see through Chang'an more and more.

……

After the preparations were completed, Su Xiao introduced the production principle of the "virus library" to Bei Chang'an.

"I know two ways. ”

Don't Chang'an drank the milk and motioned for him to continue.

"The first one, which is easier but time-consuming. To put it bluntly, it is to crack the common killing software on the market and completely copy their "virus database", saving time and effort, and there is no need to collect it yourself, but there are also disadvantages......"

At this point, he paused

Don't Chang'an looked at him, and then said: "Children can distinguish between right and wrong, and adults only look at the pros and cons." To put it bluntly, what are the drawbacks?"

"There are many disadvantages of this approach, and once you leave behind, there will definitely be hidden dangers, but the main thing is the issue of interests. Think about it, if you use other people's "virus databases" to grab other people's markets, and then pay them for free? Who would want to? In addition, direct replication will cause the "virus database" to be too bloated, and if there is a mistake in the engine, the anti-virus effect will be greatly reduced. But fortunately, the pre-production doesn't take much brains......"

Before he could finish speaking, Bei Changan waved his hand and interrupted him, "Say the second one." ”

An antivirus software, the production of a "virus database" is particularly crucial, and he doesn't really want to reproduce it.

It's not that I'm afraid of "leading the war" in the future, the most important thing is that it doesn't have its own characteristics, and it's not easy to gain public recognition.

Su Xiao looked at the computer screen and changed his words, "The second one is more troublesome." You have to collect everything yourself, which is time-consuming. Moreover, the feature code has to be done by yourself, and the requirements for the virtual machine are also very high. ”

"How long will it take?" asked Bei Changan.

Su Xiao held his chin, shook his head and said: "I can't guarantee it, this thing is not that simple, generally large companies have professional groups, as far as the three of us are concerned, the time is really hard to say." There are so many layers involved, such as programming, patch upgrades, serial number purchases, and then publicity and promotion, etc., which are very complicated. It's not virus-specific software, so it's really hard to say. ”

Don't Chang'an looked at the dog, then at Su Xiao, and said calmly: "In terms of production, there are only two of us, and the dog is just the commander-in-chief of the navy." ”

Su Xiao glanced at the dog.

The dog opened his mouth and asked, "What is the commander-in-chief of the navy?"

Don't Chang'an ignored him, and asked Su Xiao again: "Three months, are you confident?"

"I can only try, but I don't have much hope. ”

"Okay. ”

……

"Third brother, what should I do?" asked the dog, sitting on the bed.

Bei Changan turned on another computer and called him over: "What you have to do is very simple, what I taught you before, register social accounts, the more the better." Any BBS related to network maintenance is an area you want to get involved in. ”

"What is network maintenance?"

Don't Chang'an glanced at him, his heart was like ashes, and he listed several related forums for him.

During this period, Su Xiao interjected on the side: "Network maintenance is the person who cleans the network and computer, so that people who surf the Internet can surf better." ”

The dog nodded incomprehensibly.

……

After everything was ready, Su Xiao began his work.

Don't Changan watched from the sidelines, he found that Su Xiao's computer level had reached a certain depth, and the code was very smooth, but the speed was still very slow, and it was still incomparable to an old programmer like him.

When Su Xiao was typing the code, Bei Changan suddenly thought of something.

Once, when he was writing a program, he used antivirus software to kill a file that had been made by mistake.

The killing of soft uses the technology of the virus database, and there is often a phenomenon of "new viruses cannot be detected, and they are wronged if they are not viruses", for which the boss scolded him many times.

At that time, Bei Changan was thinking, why not use the technology of "cloud security", so that "cloud security" can monitor the abnormal behavior of software in the network through a large number of clients in the network, obtain the latest information of Trojans and malicious programs on the Internet, push it to the server for automatic analysis and processing, and then distribute the solution of viruses and Trojans to each client.

In this way, the entire Internet becomes a super big antivirus.

……

"Wait a minute. Don't Chang'an interrupted him.

Su Xiao asked, "What's wrong?"

Don't Changan thought for a while and said, "How often will the virus database be updated in the future?"

"It's usually a day, and some are measured in hours. ”

Bei Changan said again: "Can the database be automatically connected to the network?"

"No, it has to be updated manually. ”

Bei Changan nodded and motioned for him to continue.

……

The technique of identifying viruses through virus databases is far from perfect, and there is often a phenomenon of "new viruses cannot be detected, and they are wronged if they are not viruses".

Bei Changan decided to wait for the "virus bank" to be completed and then experiment with another method by himself.

If it is successful, then its own killing soft will definitely rise to a higher level and attract a huge customer base.

……

The three stayed in the rental house and didn't leave until 7 p.m.

During this period, Don't Chang'an was lying in bed, thinking about "cloud security".
