Coquettish Rebirth

What is the best way to get it done once and for all?From a certain point of view, we should first create a "medical" theory, which is a bit like traditional Chinese medicine. Even if you use various weird theories or philosophies, as long as you establish a set of logic, you can combine the symptoms and treatment of the disease. This is a good theory.To put it simply, after the theory is established, when encountering a new thing, it may be possible to analyze the disease and there will be a corresponding treatment method, and at least it can be a palliative.

From this point of view, if a so-called intelligent anti-virus software is built, it will automatically analyze the harm caused by the virus, and then use the "medical" theory that comes with the system to deal with the virus, and finally download it through the Internet or other What is the way to complete the files deleted or modified by the virus, won't this prevent the virus database from proliferating in large numbers?

But the problem is that something similar to intelligence must have certain system resources to scan and monitor all the time - after all, it is necessary to monitor the actions of all software and then make judgments to know whether the virus is harming the computer. ah!And this would definitely slow down the computer, and no one else needed to talk about this kind of thing, as Jia Hongjian could figure it out on his own.Then obviously this method will not work.

So do you want a proactive defense method?When the system downloads or installs or adds something, it will automatically scan for new things?Active defense through this method?The problem is that this kind of scanning itself also needs a virus signature code to correspond to it!Otherwise, if a senior hacker with egg pain is full, he will create a brand new virus.If there is no characteristic of previous viruses, then this active defense system will not be able to detect it at all?

If you think about it this way, in fact, the current anti-virus measures are a bit like a Huaxia Hi-Tech Building-although there are people who work in it every day, because there are shops and other things, because there will be tourist groups coming every day in the future, So in fact, countless strangers will come in this building!Correspondingly, all kinds of software will be installed on the computers of every household!Then, how can the security guard prevent murderers from entering the building?You can only hold the portraits of the wanted criminals at the entrance and match them one by one!If the murderer had plastic surgery or had no criminal record at all, the security guard would definitely not be able to recognize him, right?After all, the security guards have no way to detect whether all the people who enter the building have the idea of ​​doing bad things in their minds.right?

If the murderer has never been caught.As an analogy, if computer viruses cannot be completely removed from the Internet, then in the end, there must be more and more arrest warrants in the hands of security guards, and the need to perform "face inspection" on people entering the building will also become more and more complicated. The longer - for example, if the security guard only has a wanted warrant in his hand.Of course, it will be ok for a second.But if the security guard has a thousand wanted warrants.Or even [-] wanted warrants?What to do?

In reality, it may be possible to purchase various computer systems, store wanted warrants through the computer system, and then compare each person's face with the face in the database according to the intelligent system.However, this kind of analysis and comparison also requires characteristic standards-generally speaking, the police field seems to be compared according to areas that are difficult to change, such as near the eyes.And on computer viruses.There is no such place that is particularly easy to be judged!How to do it?

If there is no such algorithm that relies on the features near the eyes to judge and analyze the face, it can be said that if you only rely on the photos on the wanted warrant to judge and analyze the face, you can definitely make all kinds of ridiculous jokes—absolutely full of all kinds of misjudgments , full of all kinds of mistakes!From this point of view, there is really no way to do it well, at least in a short period of time!Because like this kind of discovery of the unique characteristics of the virus and then various analysis and discovery, it will take about ten years for algorithm optimization alone?Even if it doesn't take so long, it won't be less than three to five years at the earliest, but Jia Hongjian and the others are in a hurry to use it now!

Otherwise, let's think of a way to ensure system security?In other words, it is to isolate the work area from the shop area first.For example, there is an electronic gate between the store area and the office area that appears every 5 floors. The electronic gate is the kind that requires a card or even a fingerprint to enter?Then there are cameras that keep shooting?In this way, even if the safety of the store area cannot be taken care of, at least the safety of the office area can be guaranteed, right?Even the elevators in the office area can use the high-tech elevators of later generations-the elevators must be swiped to start, and the floor buttons of the elevator can only be pressed according to the authority of the card after swiping the card!In this way, at least the safety of the office area is guaranteed, and we can slowly find a way to get the store area in the future, right?

So if this method corresponds to the anti-virus software...at least ensure that the virus will not damage the system?In other words, at most, it is the kind that destroys external software or keeps opening new windows, which slows down the computer, but cannot destroy the system kernel?

Good idea?It coincides with Jia Hongjian's idea of ​​the virtual system, doesn't it?Isn't the idea of ​​Jia Hongjian's virtual system itself to create a virtual environment so that viruses can't attack the security of the system itself?Don't you just want to enclose the virus in such a virtual system?Could it be said that...it would be a waste for Jia Hongjian to develop any anti-virus software?

Of course not!You must know that if the virtual system that Jia Hongjian and the others built contained system files, the size would be about 60m!If you add some anti-virus functions, how big is this?After adding the function of the firewall, the total size of this thing should not exceed 100m?If this is to be used by users with small USB drives, how should they be used?Therefore, Jia Hongjian's original plan was to launch virtual desktops first, or antivirus software that included virtual desktops. After occupying the market through the free model, we will try virtual systems step by step.Then when trying the virtual system, we can also use the signboard of windowspe, that is to say, it is a small software released for free to let everyone install better and faster!Then slowly add various mobile office functions - at that time, the encryption function and so on will be introduced, so as to avoid the loss of the USB disk and leak various secrets.Then integrate with the mobile phone system step by step to make a system that can span mobile phones and desktop computers!

This is Jia Hongjian's fundamental plan!So now, although the research is relatively late, if we want to launch the virtual desktop and free antivirus first, can we use the idea of ​​the virtual system in the previous part?For example, the software runs automatically after the computer is turned on, and although the software itself does not contain system files, it can create a virtual environment on the desktop.In this virtual environment, the destruction of the virus will not harm the machine?Then you can also set various virtual restore points. After being infected with various viruses that slow down the running speed, can you restore to the state before the virus with one click?

From this point of view, at least it has a certain protective effect, right?At that time, even if the update of the virus database is slow, there is nothing to be afraid of, right?After all, it is impossible to cause too much harm to the consumer's computer - there is really no way to deal with it. Once the consumer restores it, the virus will be the same as if it has never been downloaded. What kind of virus database update is needed?So in fact, as long as such an anti-virus software has a basic function, it can check and kill the system before the virtual system is installed, so as to avoid all kinds of viruses that have settled in the system in advance, then it will be fine!At most, we just add a firewall, and then control the data transmitted by the virtual system to the extranet, and do not allow unlicensed software to communicate with the outside world. Isn't that all right?Even add some anti-phishing website content to prevent consumers from being deceived by phishing websites and entering various passwords.Even adding some functions such as online shopping bodyguard... In this way, because there are not many virus databases, the advantage of startup speed will be greater compared with other anti-virus software, right?

Even after the hard disks get bigger and bigger in the future, we can create a function to restore other hard disks. When such a restore point is created, not only the system can be restored, but even all kinds of installed software can be restored. Can be restored!Even if it is possible to keep the current work progress or chat records... that would be perfect!

"Do you think it is reliable for us to do it this way?" Jia Hongjian expressed his thoughts to Osvaldo and his group.After he finished speaking, a group of anti-virus and protection experts suddenly stared at each other!Looking at this scene, Jia Hongjian felt a little bit heartbroken, okay?Can your sister do it?

As a result, tens of seconds later, the group of powerful people who were looking at each other turned their heads and looked at Jia Hongjian in surprise, "Sir... your idea... can't be said to be wrong... no! It should be said that it really triggered A new path leads to a new way of thinking! This is just like a virtual machine. If we let the virus have nothing to destroy, and we can destroy the virus-infected system at any time, we do not need to keep pace with the time. Advanced anti-virus capabilities!" Osvaldo said a little excitedly!

"That's right, if we build a shielding system like the blood-brain barrier of the human body, then the virus infected on the other side will not be transmitted! This can be said to be a brand new idea!" The other powerful people also agreed echoed, and while talking, they looked at Jia Hongjian.Their eyes were full of surprise and admiration. They really didn't expect Jia Hongjian to come up with such an unexpected way! (To be continued..)
