Reconnected to the No. 1 satellite, Zhang Yang opened the analysis server in the satellite, the whole satellite has a variety of functions, and its server has a specially equipped analysis function of the server component, its computing speed under the same conditions is at least 50% more than the ordinary server.

This kind of analysis of the law is the most suitable thing to do, how huge the data that military satellites need to analyze, although the two are not quite the same, but at least the efficiency of the server is several times higher than that of the public.

Import all the files into your own satellite-1, and Zhang Yang directly let the satellite start the analysis. Satellite analysis over there, Zhang Yang is not idle, this time the mutation of the assassin virus gave Zhang Yang a lot of inspiration, first of all, his firewall is not invincible, although it may maintain a fairly strong lead in the surname, but even so, although it can block some viruses, but it can't stop all viruses.

For example, if the author of this mutated version of the assassin virus changes the penetration surname of this virus a little more, even the flamboyant firewall will have great difficulty in defending against such a virus.

I can't help but think that whether it is all anti-virus in the past life or now, as well as the way to prevent viruses, all anti-virus methods need a huge database support, which is often referred to as a virus database, and people who are mediocre anti-virus software will find that when your anti-virus software is updated, most of the time it is not the function of the anti-virus software itself that is updated, but its virus database is being updated.

This sentence is used in the virus and security circles, no matter how the antivirus software develops, it will always be only a passive defense, and the development speed of computer viruses, almost every hour there are dozens of new ways of infection of the virus, although the major security companies have established their own virus warning center, but this virus warning center is only a reminder in advance, so as to enrich the company's virus database.

But there is a drawback to everything, that is, antivirus software is getting bigger and bigger, and it takes up more and more computer resources, so many individual users don't like to use antivirus software. Originally, the surname of the computer can be updated too quickly, and the surname of everyone who buys a computer is not enough, and almost one-fifth of the surname can be used to install an anti-virus software, who is willing?

For example, this time the assassin virus mutated virus, these security companies are helpless at all, and the network security of everyone in the world is under the threat of this virus, even if the other party is mainly aimed at China, some foreign computers are inevitably infected with this virus.

After thinking about it for a while, Zhang Yang didn't come up with a reason, opened QQ on the desktop, and Zhang Yang logged in to the QQ he commonly used.

As soon as "Di Di Di" logged in, the crisp message prompt sounded, and as soon as Zhang Yang saw the news, he quickly threw what he had just thought into his mind.

Li Keqing (782364**) 19:22:10 What are you doing?

Li Keqing (782364**) 19:32:53: Isn't it there?

With two messages in a row, Zhang Yang quickly returned: Here, I just forgot to be on QQ.

Li Keqing: Ah, hehe, today I sold six more computers, and I have more than 700 achievements alone.

Zhang Yang smiled slightly, found a cheering expression, and then typed again: Yes, hehe, it's still our family, come on.

The three words of our family are mysterious, generally speaking, as long as you don't hate MM, you say these three words, once or twice may mm will object, but after a long time, MM will not say anything, then you will continue to say these three words, MM will slowly have a special feeling for these three from the subconscious, hehe, that is fast from you to the girl.

Li Keqing: I hate it, who is from your family, don't talk nonsense.

Zhang Yang: Haha, the weather is good today, the wind is beautiful, you should be the last day to go to work tomorrow, and we will start school the day after tomorrow. Zhang Yang wisely changed the topic and took a preventive shot first.

Li Keqing: Well, yes, I probably did the math, I made a total of more than 4,000 yuan, by the way, do you know who paid the fine for you?

Looking at Li Keqing's question, Zhang Yang hesitated, he didn't know if he should tell Li Keqing, after thinking about it, Zhang Yang still decided to tell her that it was better to say this kind of problem directly, otherwise it would be too troublesome to explain it later, anyway, he didn't have any other thoughts about Tan Yudie.

Zhang Yang: Tan Yudie helped me pay it, and she wanted me to participate in the national computer competition on behalf of the school's computer club, so she helped me pay the fine.

Li Keqing: Oh, that's it, is Tan Yudie the number one on the school flower list? I've heard that the family is rich and beautiful, right?

Li Keqing's question made Zhang Yang's eyes light up, it seems that our work is not done in vain, at least Keqing already has him in his heart, otherwise, he would never ask this kind of question. Even if gossip is a woman's natural surname, no woman will gossip with a man about how beautiful another woman looks, unless, she cares about this man's opinion in her heart, so she wants to understand these issues from the side.

"Well, her mother is the chairman of Jinghai Group, and her family is quite rich, and in her opinion, the 50,000 yuan is no different from the five yuan in our eyes. looks very beautiful, otherwise how can I become the first on the school flower list. But....... Zhang Yang paused deliberately, he wanted to tease Li Keqing.

"But what?" Sure enough, Li Keqing quickly replied to the message.

"But it's not as beautiful as our home." Zhang Yang quickly made a drooling expression. Although he couldn't see Li Keqing's expression, Zhang Yang could imagine that her little face might look like a red apple again.

"I won't tell you this, but they rich people really don't treat money as money, when I was having dinner with Sister Zhao at noon today, a couple quarreled, ordered a table full of dishes, didn't eat a bite, and just packed it and threw it away." Li Keqing said quickly.

Zhang Yang was stunned for a moment, packed and threw it away? Pack it up and throw it away! A flash of light flashed in Zhang Yang's head almost instantly, and he quickly thought of a possibility! It may even be a rather bullish anti-virus method, Zhang Yang almost couldn't wait to leave a message to Li Keqing: "Keqing, tomorrow we will assemble our robot, you think about what shape to use first, I will now write the chip program of the robot." ”

"Ah, can you assemble it? Okay, then you go get busy. ”

Turning off the dialog box, Zhang Yang quickly opened his firewall, and Li Keqing's words just now directly lit up one of Zhang Yang's thoughts, pack it and throw it away! After being attacked, these two viruses will quickly launch a counterattack against the source of the attack, and directly follow the opponent's attack data flow to search for the opponent's real IP.

And the infected worm that Zhang Yang used to assist in the invasion was modified by him, and his infected worm virus can monitor the entire system, just now Li Keqing's words gave Zhang Yang a lot of inspiration, pack it and throw it away! It's like when we go to a restaurant to eat, now many restaurants have tablecloths on the tablecloths with the surname once, and when the guests finish eating, they just pack the tablecloth and throw it away, and the table is still clean.

If we compare viruses to leftovers on a dining table, and computer systems and files to a dining table, then if we build such a tablecloth in between, then all the problems will be solved. If you get the virus, as long as you throw away the tablecloth with the surname of the first time, along with the garbage, isn't the system still clean?

When the time comes, you just need to change the surname tablecloth to a new one, isn't it? Although this problem seems simple, it is not simple to do at all, for example, strictly speaking, this model is not new, the firewall is actually similar to this principle, all the data needs to be monitored by the firewall, as long as there is a virus, it will be found, and then alarm, in order to achieve the purpose of preventing the virus.

This mode is true, but all the firewalls on the market are not thorough, and its virus detection mode is still through the cooperation with the anti-virus software, by detecting the illegal behavior of the program, and then matching with the virus database of the anti-virus software to achieve the purpose of prevention.

Zhang Yang is naturally not doing this, his whole person's eyes are beginning to shine, this program does not need to be too big, just modify it directly on the basis of infected insects. Zhang Yang first quickly and completely modified the mode of infecting insects, completely removed its active infection and spread function, and at the same time removed the parts that affected the system files and opened the back door to the computer.

In this way, the infect becomes a piece of software, not a virus. What Zhang Yang needs is to make a fuss about the detection function of infected insects, first of all, Zhang Yang wants to put a protective film on the whole system, this protective film is just a name, it is an intangible thing, speaking of which, this thing has the same thing as the analog system, which is equivalent to wearing a layer of clothes for your original system, and this layer of clothing can be pulled off at any time.

It's just like our mobile phone film, but this protective film will not affect your use, you can still use the software in the system, as well as various functions, but once there is a virus intrusion, the computer virus will work illegally.

That's for sure, no matter what kind of computer virus it is, even if it's a, it will run autonomously if it wants to infect the system and achieve its purpose. This membrane will monitor the entire system, and any program that runs autonomously and illegally cannot escape its surveillance.

Whether it is modifying the system file, or other actions will directly hit the membrane, after detecting this behavior, the infected insect after the modification will directly copy a virus to modify the system file out, the computer virus is not a person, as long as this file is detected, it will automatically infect and mutate.

At that time, as long as the membrane is closed, then the virus is like a turtle in an urn, and you can't run away if you want to, just throw away the packaged membrane.
