More than half of the prom.

The boys in 616 and the beauties in 602 have noticed one thing.

That is, when Ye Kai and Yu Ge were dancing, they always looked at each other like Haiti.

These two unkempt people suddenly became so gentle.

People don't get used to it.

Zhou Yang came over and asked Bei Chang'an: "Third brother, what's the situation?"

Don't Changan shook his head and said, "I don't know." ”

Chen Jiuqiang looked at the two and guessed: "Is there a play?"

Su Xiao kept nodding beside him.

The dog held his chin with his hand and said slowly: "I finally know why the boss didn't go back to the dormitory when I was eleven......

As soon as the words fell, everyone's eyes were on him.

……

On the way back to the dormitory, the boy from 616 mentioned the incident again.

Ye Kai couldn't stand Chen Jiuqiang's stalking, and finally admitted that he had officially started dating Yu Ge.

Zhou Yang asked him, "Where did Eleven go?"

Ye Kai only smiled and didn't speak.

The five were surprised.

Bei Chang'an was also surprised.

He thought of this result, but he didn't expect this kid to move so fast?

……

15 October, 2001.

Lao Tian sent this week's report to Bei Chang'an on QQ.

Don't Chang'an took a look, and the number of downloads has stabilized, breaking through the 1500 mark.

This is not a good grade, and it is not bad.

The reasons for this situation were analyzed by Don't Chang'an.

He thinks there are two.

First of all, the forum traffic of the "Network Management Home" has reached saturation.

The only people who come to the forum every day, no new members join, although he has put the post to the top, but the effect of promotion is not as good as before.

In order to change this situation, the forum must open up new means of publicity, otherwise over time, the sales of software will definitely be deadlocked.

Second, the thinking of Internet practitioners is too limited.

They have not yet taken into account the tremendous help that the management system can be for the operation of Internet cafes.

This has to be done slowly, due to the general environment of the times, it is useless to be in a hurry.

Don't Chang'an told Lao Tian his thoughts, and Lao Tian promised him to discuss with his partners in a few days to see if he could increase publicity and increase some exposure.

But Lao Tian felt that this idea was unrealistic, after all, the budget was limited.

Don't Chang'an let him try, if it doesn't work, forget it.

……

In addition to "Chang'an Network Management", Don't Chang'an put all other energy on WO268.

He's thinking about some other ways to promote it besides rogue bondage.

But after thinking about it for a long time, I didn't have a clue.

One day, when I was in C language, Professor Ma, who was the lecturer, put forward such a point.

"This code is something that a lot of antivirus software will use. For example, the familiar Jinshan drug bully, Ruixing ......"

Antivirus?

Don't Chang'an's heart moved, thinking that this was an opportunity.

……

The development of antivirus software in China can be divided into three processes.

The Charging Era.

Free Times.

Upside down era.

In 2001, the three types of soft killings in the world were basically charged.

Even later, Jinshan launched the "Blue Revolution" and lowered the price to a low price of 50 yuan, but it still couldn't avoid the fact that it asked for money.

Through the release of "Chang'an Network Management", Bei Chang'an has been deeply aware of the temptation of free software to the majority of netizens, especially to kill soft.

A free killer may not bring considerable economic benefits in a short period of time, but the traffic it generates is incomparably huge.

It's all money!

……

Right now, 360 hasn't yet!

Computer Butler, not yet!

Don't Chang'an remember, the killing of soft that really opened the free era was 360 in 09!

……

The most turning point of 360 was to bundle it with other software and advertise it on TV.

Due to its high quality and free cost, 360 Security Guard has suddenly gained a rapid demand from civilian users.

Later, what is even more incredible is that in just three months, the installation rate of 360 security guards reached 40%, and then in about two years, it increased to 60%.

Due to the pressure of 360, Ruixing and Jinshan have no market, and in 2010 and 2011 respectively, they all announced that they were free, and the domestic killing soft has since entered the free era.

Now, Beichang'an, who is in 01 years, is eight years earlier than them!

……

Looking forward to the development process of killing soft, Don't Chang'an kept sighing.

This is completely "poisonous" out of the rivers and lakes!

Kill the soft!

Why didn't you think of it?

In the case of the whole network charging, if you launch a free killing software, you can not only quickly occupy the market, but also get the opportunity to promote your own software for free.

Secondly, with the advent of the e-commerce era, you can also continue to operate by launching "claims insurance", and take the lead in leading the soft to enter the "inverted paste era"!

It's an opportunity, and it's hard to come by!

……

in the classroom.

Professor Ma's class, don't Chang'an have no intention of listening to it again.

He drank milk and collected his thoughts.

The most important thing to do is the "virus database"

Looking at the well-known domestic killer soft, which one does not have a million "virus pools" as support?

Because only in this way can you be authoritative and recognized, otherwise why should people use you?

"Virus reservoir"?

The first question stumped Bei Chang'an.

He's just a programmer, and he can make software and websites, but he doesn't have the concept of "virus database" at all.

Antivirus software is based on existing viruses, according to their coding rules to make boilerplate code, identify the virus, after identification, will use the built-in uninstaller to delete it.

Therefore, making an antivirus software requires a lot of engineering, and there are many programming languages used, such as: C, C++, E, VB, JAVA, assembly, etc.

But more importantly, the "virus database" and the "scan engine".

Not only that, but you'll also have to invent different solutions for each virus, which can lead to strict requirements for creating antivirus software.

With such a huge amount of work, it is not possible to do it alone.

……

The collection of "virus databases" and the research and development of "antivirus" methods are both very professional technologies.

In this field, Bei Chang'an only dabbled in it slightly, but he was not proficient in it.

He understands the general process, but he has no concept of the specific operation.

Thinking, at an impasse.

……

At the end of class, Don't Changan chatted with Lao Tian on QQ, and he didn't give any advice on construction.

However, he said that he could introduce some talents in this area to Bei Chang'an.

Don't Chang'an thanked him and got off the plane and went to bed.

Su Xiao was the only one in the dormitory, and everyone else went to the cafeteria to eat.

"Didn't you go to dinner?"

Su Xiao held a book in his hand and replied intently, "I've eaten it." ”

"And what are you looking at?"

Su Xiao showed the cover of the book to Bei Chang'an.

Kevin Mitnick

"Who is this man?"

Su Xiao lowered his eyes and said with a smile: "My idol, the number one hacker in the world." ”

"He wrote his own autobiography, huh?"

"No, it was written by the Chinese, and it should be pirated. ”

Bei Changan nodded, opened a bottle of milk, and asked, "Do you know how to make a 'virus bank'?"

"Virus reservoir?"

"That's right, it's a virus database that kills soft. ”

"Yes. ”

"Where's the scan engine?"

"I understand. ”

Su Xiao finally put down the book and asked rhetorically: "Third brother, why are you asking this?

"Interested?"

Su Xiao shook his head and quipped, "Don't be kidding......"

"Why do you say that?"

"You don't even have a computer, how can you do it? Go to an Internet café to do it? It's unrealistic......"

Don't Chang'an took a sip of milk, looked at the night and began to ponder.
