After a week of hard study, Qi Yan finally ushered in a free and relaxed Sunday. Pen % fun % Pavilion www.biquge.info

rejected Guo Mingyu's invitation to go out to play together, Qi Yan got up early in the morning to run on the playground, and slowly shook the cafeteria to buy breakfast, and by the way, he brought one for Yan Yue, who was still sleeping.

Li Jing went home from school on Friday, Wang Jia also went back to her aunt's house, Yan Yue didn't come back because her parents had to work on the weekend, Qi Yan took a day of class yesterday, and she played with the computer in the dormitory for a day, which was simply refreshing.

After Qi Yan came back, he woke up Yan Yue, looked at the time and saw that it was half past seven, and after breakfast, Qi Yan turned on the computer and connected to the Internet but found that he couldn't access the Internet!

I unplugged the network cable, the computer restarted, and the result was still the same.

Hardware is definitely fine, software?

"Yan Yue, what were you doing on the Internet yesterday?"

"What's wrong?" Yan Yue replied in a daze.

"It's okay, just ask. What the hell are you doing?"

"I just went to QQ, played games, and, ah!"

Yan Yue started doing it as she spoke.

"What's wrong?" Qi Yan asked her puzzled.

"I, I, I just accidentally clicked into a website, looked, saw some, east, west...... Ahhhhhhh

Yan Yue stammered and covered her face with a pillow. Seeing this, Qi Yan also understood.

"Oh, then did you continue to watch it later?" Qi Yan continued to ask.

"Oh, no! I quit right away. Really!" Yan Yue said immediately.

"Oh, that's right. ”

"What's wrong?"

"It's okay, you can get up and have breakfast, it's eight o'clock. Qi Yan urged her.

"Oops, get up right away. As he spoke, he fell asleep again.

It's just that if you accidentally click in, it won't be fine, if there is something, there should be something wrong yesterday, but yesterday Qi Yan came back from class and the computer was still good, and in the end she turned it off, so what is the reason?

It was fine before the shutdown yesterday, but I can't even connect to the Internet when I turn it on today, yes! I got hit as soon as I turned on the Internet today! That should be a large area of network paralysis!

At this time, there should have been a lot of servers and personal computers, and the LAN was paralyzed, which should be a highly transmissible virus.

In 2003, there was indeed a more powerful computer virus - worms!

Qi Yan was a computer major at the beginning, so he still has some understanding of these viruses. Especially in the graduation season of her third year of graduate school, a B virus suddenly appeared in China, especially in various colleges and universities, and the computers of medical institutions were recruited, and Qi Yan's computer was not surprised, at that time her computer was locked, and the other party extorted 5,000 yuan, otherwise all the information in the computer would be emptied in three days!

Although Qi Yan studied computers, he did not have high hacking skills, so he immediately asked his classmates for help from his mentor.

In the end, it was not cracked within three days, and then several of their computers were emptied, which is a shame, the computer major of Huake University is the best in the country, I didn't expect such a thing to happen, and her graduation thesis can only be redone!

Later, they worked together with the computer teacher for more than a week to crack the virus, and then launched the cracking software.

Stimulated by this incident, Qi Yan later spent a lot of time studying the famous viruses and their variants in history.
