Chen Hao's expression moved slightly, he pressed the mouse, clicked on the start button, then clicked run, entered a series of English characters and pressed Enter.
A black format box for DOS commands appeared on the screen. Chen Hao entered a line of commands and then pressed Enter.
Buzz... After the computer beeped slightly for a while, dozens of neat lines of code appeared below the command.
Chen Hao looked at it carefully, and then his eyes stopped on the "Private Sub Cfinite)" code in the middle layer.
"Full program?"
A strange look flashed in Chen Hao's eyes, he tapped the keyboard with both hands, entered another line of commands, and then pressed Enter.
The computer buzzed again, and dozens of lines of code appeared below the command.
The code is composed of English letters and symbols. It looks similar to the code of the previous command, but if you look closely, you will find that the two are completely different.
Chen Hao glanced around and found the same "Private Sub Cfinite)" code on the sixth line as the previous command.
Chen Hao continued to enter commands.
Codes appear one after another. Although they are different, they all have the short line of code "Private Sub Cfinite)".
The most peculiar thing is that in the code below the last command, this line of code is actually separated. The codes are separated by another code, but they are mutually consistent and seamless.
It's like adding another word next to each word in a sentence. The other words add up to one sentence. When mixed together, it becomes another sentence, and people can see the meaning of these three sentences at the same time.
"Wonderful."
Chen Hao looked at it and couldn't help but praise.
Although with his current computer knowledge, looking at these codes is like looking at a primary school student's arithmetic problems, but being able to type the code to this level is already a top skill.
Chen Hao entered the command again.
This time, no code appeared below the command, but a large garbled code appeared.
Immediately afterwards, these garbled codes began to copy themselves rapidly as if they were conscious, and the prompt box quickly extended downwards.
"It's interesting to be able to avoid system recognition..." Upon seeing this, Chen Hao's eyes suddenly became more interested.
He clicked the X in the DOS command format box, but there was no response.
The next moment, the format box suddenly flashed and turned into a huge black spider. It opened its mouth on the screen, exposed its fangs, and sneered.
"I'll go, what the hell!"
This black spider was different from the previous small spider virus. It was extremely ferocious. It suddenly appeared and shocked Yu Haibo and others who were watching.
"Hmph, you are a very small person, how dare you try to do the same thing?"
A sneer appeared at the corner of Chen Hao's mouth: "I can tell at a glance that you are not human! The mighty heavenly dragon! World Honored Ksitigarbha! Prajna Buddhas! Prajna Bama Kong!"
As he spoke, he typed quickly on the keyboard.
The computer buzzes.
Soon, the huge and ferocious black spider froze, then flickered and suddenly disappeared without a trace.
"Wow, Teacher Chen is so good at slaying demons and monsters, so powerful!"
Yu Haibo and others all smiled and praised.
"Concession, concession."
Chen Hao laughed, opened a txt notepad, and started writing code.
He had already tried it just now. Not only did the anti-virus software fail to kill the spider virus, but it was also infected by the spider virus itself.
The reason why the anti-virus software starts running after half a day after the virus is raging is because of the delay caused by the virus.
As for the anti-virus software prompting to isolate the virus and return to normal, it is just an illusion.
The virus has not been isolated, it has just been moved to the background and has no impact on the system or foreground programs for the time being.
In other words, the anti-virus software has been infected by the virus, and in turn becomes a virus disguise, paralyzing the user.
And not only anti-virus software, but other software on the computer, including the operating system, are all infected with viruses.
This virus is very cunning. It not only deeply hides files, but also has an advanced nested structure.
What does that mean?
That is, the virus can disguise itself as a normal line of code and hide it in the software code.
When the virus is latent, the software behaves normally, but once the virus attacks, the software will completely collapse.
So the surface inspection software can’t find anything.
Even if a computer expert checks the software code through the background, it is easy to overlook this normal and inconspicuous line of code.
The best thing is that this virus can also divide itself and hide in the correct code structure.
Just like what Chen Hao just saw in the background program of the last software.
Not to mention segmentation of normal code, even the capitalization of letters, spaces and symbols must not be wrong, otherwise it will lose its function and become useless code.
However, this virus can connect the divided parts through the special structure of the normal code, and under certain conditions, automatically reorganize and then activate.
Just like a wireless network, you can control different computers in different places.
Being able to do this means that there are complex algorithmic functions hidden in the virus, which are so much higher than ordinary Trojan viruses.
No wonder antivirus software doesn't work.
Speaking of which, although the structure of this virus is much simpler than that of anti-virus software, the technical content it contains far exceeds that of anti-virus software.
Under such circumstances, it was simply impossible for Chen Hao to use system programs to view the code structure of the virus.
He could only write his own code and compile an identification program with unique firewall properties.
"Why can't I understand what Teacher Chen is doing?"
"Isn't this nonsense? If you can understand, the person sitting here is not Teacher Chen, but you."
“Teacher Chen’s level of computer skills is more than enough to be a teacher at the Headquarters Computer College, right?”
"I see no problem."
...Yu Haibo and others watched Chen Hao's operations as if they were reading a book from heaven, and they were all amazed.
After a while, Chen Hao finished writing, closed Notepad, then changed the suffix name and double-clicked it to open it.
On the computer screen, the DOS command format box appears again.
Chen Hao pressed Enter.
Lines of code are automatically displayed in the format box.
This code looks like gibberish. In addition to the standard code letters and symbols, there are also Chinese characters.
Chen Hao was surprised.
This was the first time he saw a Chinese programming language, and it was in traditional Chinese characters.
The most peculiar thing is that a small number of traditional Chinese fonts are not fixed, but are constantly flashing.
Every time it flashes, it changes to another word.
The flashing time is very regular, about 0.5 seconds.
