The four of them came to the classroom after laughing for a while, and Ye Li also found that the classmates who recognized him on the road were pointing at him, and whenever he looked over, someone gave him a thumbs up, and Ye Li was extremely embarrassed.

The noon class started very quickly, and with Ye Li's talent and ability for computers, he had already learned all the things of this semester, and after the programming task was completed in this afternoon, Ye Li also began to study his own things.

After Ye Li came into contact with computers, he felt that he had an extremely high talent in this aspect, and this talent was not on the part of hackers, but on the side of hackers.

There are many types of hackers, but in general, the purpose of hackers is to steal or manipulate other people's computer information, while hackers are simply to destroy.

Ye Li's specially designed virus program has been perfected to a certain extent after a few years, although it has not been completely completed, and there are still a lot of weaknesses, but the virus designed by Ye Li can paralyze the entire computer, and it cannot be used, and the time for this virus outbreak is extremely short, so Ye Li's idea is that the opponent does not even have time to react.

Ye Li hid this virus in the computer in the academy's computer room, and every time he took a class in the computer room, Ye Li would take the time to perfect him.

The locations Ye Li chose were all in the far corner of this computer room, and even if the tutor checked it, it could be quickly covered up by Ye Li.

Ye Li has perfected a program for this virus today, but this is only a preliminary improvement, and Ye Li is not clear about any loopholes in it, so today Ye Li plans to go to an experiment.

When the class was almost over, Ye Li finally finished programming the virus, and then passed it into his mobile phone, this virus was programmed by himself, so Ye Li was not worried that his mobile phone program was attacked by the virus, and the virus was also set up as a latent program by himself.

When Ye Li left the computer room with this program, Ye Li was thinking about where to go for the experiment?

In the bedroom, only the fat man has a notebook, but this virus is not yet perfect, and if it is used to attack others, it will be discovered and chased by others, so Ye Li plans to go to the Internet café to experiment.

And after Ye Li walked out of the computer room, he also forgot that Cheng Yi said that he still had to stay in the class to select the list of contestants, but Ye Li ran to the Internet café alone to start his experiment.

Ye Li introduced the virus in the mobile phone into the computer of the Internet café, and the latent virus did not have any effect, but fortunately, Ye Li carried it out in the box, otherwise it was seen that a large amount of data kept appearing on the black screen on the computer, and the fool knew that Ye Li was wrong here.

And Ye Li began to find some computers with strong network defense through his own Jishu to conduct experiments, Ye Li did not dare to do anything about the network of the state department, and the virus in this experimental stage was probably easy to find, and Ye Li chose some large private companies.

These large private companies also have a very high degree of network security, but Ye Li is sure that he will not be able to find his location after they crack their own virus.

Ye Li selected Yunfeng Group after screening, Yunfeng Group is a large group that has just risen recently, and their network security is now in the upgrade stage, with this unstable and starting to become stronger network, it is just right for their own Shiyan virus.

When Ye Li mixed the virus into the other party's network through the other party's traffic, the virus's program was instantly discovered.

"There's an anomalous program intrusion, who's downloading something?"

Looking at this extremely simple program, the staff member in charge of Yunfeng Group's network security was about to clean it up, and looking at this thing, he also thought that it was a garbage plug-in sent by some employee playing games or downloading some movie at work.

However, according to the company's cyber security regulations, in addition to cleaning up these things, the employee must be arrested, and if such a staff member is found, half of their salary will be deducted, and these wages will be paid to the cyber security department.

And the abnormal program found this time happened to be Zhang Yu of the network security department of Yunfeng Group, Zhang Yu is a red guest, with her almost demon IQ, she is also an extremely top figure in the red guest alliance.

And Zhang Yu was also invited by Yan Qi at a great cost, but the reason why Zhang Yu came to Yunfeng Group is mainly because Yan Qi is her best friend who has been playing with her since she was a child, otherwise with the secrets on the Internet, Yan Qi would not know her name as an Internet celebrity.

And Zhang Yu, who is constantly upgrading network security, is also bored to death these days, and finds that some employees are lazy and he can get bonuses, Zhang Yu began to smile evilly to see who is lazy.

And Zhang Yu simply tapped the keyboard a few times, and all the computers in the group began to check themselves, even Yan Qi's computer.

After a few minutes, Zhang Yu's eyes widened, and the display in front of him didn't find anyone downloading games or movies or anything like that, they were all working honestly, so how did this abnormal program get in?

Zhang Yu immediately became alert, the plug-in that did not come in from the entertainment aspect was obviously very likely to be a virus put in by others, and at a glance just now, this program made the computer run slow at most, and I didn't see that it was a virus.

Zhang Yu was about to check the indented handler when he suddenly found that his computer was not responding.

"Didn't you hack me?"

Zhang Yu didn't have any reaction no matter how he typed on the keyboard, and immediately understood the horror of the seemingly simple abnormal program just now.

When Zhang Yu took out his laptop and connected to the company's network, he began to disinfect the company's network with the antivirus software in his notebook.

"Hmph, play with my red octopus, you're still tender, and you accidentally hacked in, let me get rid of you now."

Zhang Yu's notebook stores his own programmed antivirus software, although this software does not say that it can kill all viruses, but some conventional and known viruses have a great effect, even if they can't be cleaned up, they should still be able to clean up under their own deep cleaning, after all, the people who attacked Yunfeng Group can't be those big hackers, they haven't been bored to this extent.

When Zhang Yu's anti-virus software was running, the staff in the Yunfeng Group began to notice that the computer was running slowly, but it was immediately back to normal after a few minutes.
