Stepping on the land of China again, Ye Hao's mentality was completely different. When he left three months ago, although he already had the system, his confused mentality has always been with him. Three months later, returning to the familiar country again, looking at the land that raised him, and breathing the air soaked in the sun, Ye Hao's whole person relaxed-this will be the world where he will show his strength, and this is the root of the Chinese nation!

Coming out of the terminal of the Capital International Airport, the first message Ye Hao received came from Yelena thousands of miles away: "Dear Ye, I know that you are not an ordinary person, and I can't be your fetters, but please believe that you will be the only one for the rest of my life, kiss you —— Yelena!"

After a moment of distraction, Ye Hao quickly cheered up, a husband can't be without power for a day! If you want to "get drunk and lie on the knees of a beauty", the premise is to "wake up and take charge of the world".

Ye Hao first found a hotel to live in, and then toured Yanjing with a relaxed mood. Although he has already traveled all over the streets of the capital during his four years of college, this visit to Yanjing with memories is unique.

Seven days later, Ye Hao, who was relaxed, began to implement his plan.

………………………………………………………………

Ye Hao is ready to start charging the antivirus software "Scavenger" that has already been launched first.

There is also a sensational incident ahead of the "scavengers".

Originally, after the "scavenger" was uploaded to the Internet, it was half dead, although it had anti-virus skills

It can be very tough, but it lacks the necessary publicity. Although users who have used it speak highly of him, the number of users has grown very slowly by word of mouth among users.

Of course, with its powerful anti-virus function, "Scavenger" will definitely occupy a place in the antivirus software market at some point in the future.

At this time, an unexpected thing happened.

One day after Elena was recalled to the White House by her father, Kopp, the White House's external propaganda page was hacked.

As a matter of fact, this external propaganda page of the White House only has a propaganda function, and is used to publicize some policies of the American government and other propaganda directions, and does not involve any secrets. As one of the most visited government websites in the world, the chances of being noticed by hackers are very high, so the team that maintains it behind the scenes is also quite professional and keeps all kinds of attacks from all over the world out of the website.

At 10 o'clock in the morning, all the normal content on the White House webpage disappeared, and a cartoon appeared on the page: Kopp, the commander of the United States, was lying on his back on the ground, and a big black foot was stepped on his fat belly;

The maintainers of the White House web page acted quickly, but to a disgrace: half an hour had passed, and the cartoon was still hanging high above the page.

Then something even worse happened, when they discovered that Wings of Doom had planted a Trojan horse on the White House website, a stealthy program that would be difficult for even professionals to detect, and its main working principle was to infect every computer that logged on to the White House website, and then sent the IP address of the other party back to the Wings of Doom's database.

Then the program will lurk in the opponent's computer, once the "Wings of Doom" sends a remote command through the IP address that has been obtained, the Trojan virus will automatically activate, and then frantically self-replicate, so that the opponent's computer will be overflowed because it occupies too much storage space, until the threshold is exceeded, and the computer's system will collapse.

In just half an hour, more than 10,000 computer terminals across the United States and Bluestar were infected with the virus and paralyzed in a short period of time.

System maintainers at the White House website are trying to take back control of the page while trying to write an antivirus program to get rid of the virus. However, the hacker was clearly a master, and neither of these things was done in a short period of time, while the number of infected computers continued to grow.

At this time, Yelena, who was in the White House, accidentally learned of the situation and remembered that Ye Hao had given her a USB flash drive, which contained an antivirus software called "Scavenger". Ye Hao asked Yelena to find an opportunity to help publicize it, but after separating from Ye Hao, her mood was not high, so she forgot about it.

Now knowing that the White House's website is being hacked and planted with a virus, Elena remembers about it. Since being rescued by Ye Hao from dozens of terrorists, Yelena has begun to have a bit of blind worship for Ye Hao.

So Elena took the USB stick with the "scavenger" to the White House cyber office and asked the technicians to install the antivirus.

The cybersecurity staff at the White House didn't agree at first, who knows where this antivirus software called "Scavenger" came from? But at Elena's insistence, they had no choice but to accept that the eldest lady was the daughter of their boss?

After the White House cybersecurity staff plugged the USB flash drive into the port, the "scavenger" began to install it on its own, and it took less than five minutes to install it. The technician waiting next to the server was surprised by the speed with which the "Scavenger" was installed, and by this time the "Scavenger" had already begun to work.

The virus is disguised as the system's graphics processor, and its activation command is "delete". The hacker who wrote this Trojan virus knows people's psychology very well, and when ordinary people find that there is such a program in their computer, the first thing they think of is to remove it, how can they get rid of it? The simplest, most direct and effective way is to delete it, so the hacker will take "delete" as the activation instruction of this Trojan virus. As soon as you click "Delete", the Trojan will explode instantly, and it will start to replicate itself rapidly until the system crashes.

Ye Hao's antivirus software for Yelena already has some characteristics of primary artificial intelligence, as the king of the network, even if it is the top master of human beings on the Internet, it is an ant when it comes to artificial intelligence. Just like an ant, no matter how powerful it is, it can't be a match for humans, even if this human is just a newborn baby.

The "scavenger" quickly found this virus program on the website of the White House, which is not very large, only about three trillion. The "scavenger" began to analyze how the program worked, and in less than a minute there were results, it turned out that the virus program was not complete, and if you wanted it to work, you had to enter the activation command. And this activation instruction is "Delete".

Of course, the "delete" instruction itself does not have this ability, because this is the function of the system itself, but there is one point that cannot be ignored, the operation of the system itself also needs to be processed by data. For example, when you want to delete a file from your computer, you will right-click to open a dialog box, and then use the left button to click on the "delete" command, and the computer will receive this instruction, and will calculate the result through the system internally, and then complete the instruction through the system program.

This is how the computer works, all the instructions are pre-designed, to execute a command, you have to choose the matching program from the pre-set data, and when you issue the command, the computer will come up with the corresponding result according to the pre-set calculation method.

This Trojan virus works according to this principle, it is associated with the "delete" instruction in the computer, once the data related to the "delete" instruction is run in the computer, it will treat this operation as an active instruction, and then the virus will also run.

Figuring out how the virus works, the "scavenger" quickly found a solution, first he used the virus as a blueprint and rewrote a number of programs in it, and through its rewriting, the virus became a diametrically opposed program.

To put it simply, the original virus has the ability to infect and self-replicate, and after the modification of the "scavenger", it has become a special program for this virus, any program that is more than 80% similar to it, it can be found in the computer, and then start the antivirus program - it will actively set up a folder, including itself and the target program, and when all this is done, it will execute the last instruction - "delete" the folder.

The virus replicates itself with only one purpose, which is to fill up the entire disk space and then "pop" the computer, because the virus cannot be deleted directly, and it is at the core of the system, so there is almost no way to solve it. However, the "scavengers" have found a very simple, but effective way to do this, and that is to load the virus into a new folder and delete it without going through itself.

In less than ten minutes, the "scavenger" finished its work, and the White House website was back to normal. Later, the network technicians of the White House website issued an announcement informing the public of the process of the cyber attack, and hung up a special anti-kill program written by the "scavengers" on the web page to facilitate the download and anti-virus of infected computers.

The crisis passed, and the "scavenger" became famous in one fell swoop!

In this incident, no one will doubt that the cybersecurity officers of the White House will finally win, but the "scavengers" who were able to defeat the provocations of hackers in a very short time are the great!

At the press conference that followed, the White House press secretary was full of praise for Yelena and the "scavenger." It was also the first time that Elena appeared in official American propaganda since the terrorist attacks, and it was a great help to her image and that of America's first family.

The White House's propaganda focus is on Yelena, while the media focus is on the antivirus software "Scavenger".

Through media publicity, "Scavenger" became an instant hit, and the number of downloads of major forums exceeded 10 million on the day of the press conference. With the extension of time, the number of users of "Scavenger" has increased by leaps and bounds, and it has exceeded 50 million before Ye Hao returned to China.
