Chapter 43 Self-protection to ensure your safety (6)
"No." Song Luming thought about it carefully. Last week, he browsed the news page on the Internet, chatted with his friends for a while, and checked his mailbox.Could it be...

"Last week, there was an email of 'Xiao Lin Guang Ji Joke Collection' in my mailbox. I clicked on it, but it couldn't be opened, and then the computer screen was completely black..."

Song Luming opened his mailbox while speaking.Cousin took the mouse, clicked "View this email", and found an attachment named Laugh.hal inside.As soon as my cousin tried to execute it, the hard disk light flashed wildly.

"Not good!" said the cousin, while abandoning the mouse, attacking with both hands, and pressing the three buttons, the task list was presented in front of them.My cousin checked it carefully, and found no WScript process, which is common in mail viruses, but an unknown process of MSHTA.

"There must be a problem with this process!" My cousin said, and immediately killed it with the process manager in "Windows Optimization Master"-as expected, the hard disk stopped ringing.

The cousin opened the resource manager, pointed to the C drive and said to Song Luming: "Look, there is a hand holding the letter of the C drive—your C drive has been shared!" Song Luming was taken aback.

The cousin then checked and found that the size of Io.sys in the root directory of the C drive was wrong—from 219K to 3K, and it was corrupted by the virus again!

Song Luming was dumbfounded: "How could this happen?"

Cousin worked for a long time, then raised his head and said to Song Luming: "Everything is done! You can use it normally. But..." Cousin emphasized, "Recently, email viruses on the Internet are flying all over the sky, and most of them have unspecific themes. With various attached files, it lures people into being fooled. You have to be careful not to open emails from unknown sources.”

Song Luming nodded: "I remember it." Then he sighed: "My 'Statutory Internet Day' was ruined by the virus, a lesson learned a lot!"

Burglary sparked by video
On March 2005, 3, the father of Lou Wei in a village in Hubei Province took back the stolen cash from the county court. He said with emotion: "Although thieves are hateful, my son is also responsible for the theft of my home."

What's going on here?It turned out that just after the Spring Festival, Lou Wei, who was at home on vacation, went to an Internet cafe in the county town to video chat with his good friend Yuan Ping.Yuan Ping and Lou Wei were classmates from elementary school to junior high school, and Yuan Ping dropped out of school later.She defected to her older sister who was married to Yichang City, and worked as a network administrator in an Internet cafe run by her brother-in-law.

The two quickly chatted openly.While talking, Lou Wei couldn't restrain the joy in his heart, and told Yuan Ping that he just went to the bank to withdraw a large sum of money.Yuan Ping was full of suspicion: "How could your family have a lot of money? Besides, even if you have it, you can't get it!"

When Lou Wei saw that Yuan Ping didn't believe him, he was anxious to swear that everything he said was true.

Yuan Ping laughed at Lou Wei with a look of disdain: "Are you desperate? How about going to the bank to withdraw money in a dream? If it is true, you take out the money and I see it to prove that you are telling the truth, otherwise It's just bragging."

Lou Wei was hesitant, worried that Yuan Ping would laugh at him for bragging, and also afraid that others would see it.But Yuan Ping insisted on asking Lou Wei to take out the money.Unable to resist, Lou Wei took out a wad of cash on his body and showed it to Yuan Ping via video.

When Yuan Ping saw such a thick stack of banknotes, he made a wrong idea, so he found an excuse, went offline in a hurry, found his new friend Li Jun, and planned to steal money from Lou Wei's family.

Yuan Ping and Li Jun sneaked back to their hometown from Yichang.After the two met at Yuan Ping's house, they immediately went to Lou Wei's house to scout the situation.It just so happened that there was no one in Lou Wei's family that day.Yuan Ping and Li Jun broke open the door lock and stole 6800 yuan in cash from Lou Wei's house.

After the cash was stolen, Lou Wei's father was very sad: This is the tuition money saved for Lou Wei!Lou Wei was also very regretful.

Now that the tuition fee was lost and recovered, Lou Wei's father felt relieved and handed it over to the school directly.

The love that hurts "me"

Not long after school started, a certain district held a computer programming competition for primary and middle school students in the district.In this competition, the favorite to win the championship - Xia Guoxing, a key middle school student and computer expert, gave up the competition and left the field halfway.

When the news came out, everyone was quite surprised.Xia Guoxing is not only a man of the hour in their school, but also famous in the whole district.As long as there is a competition, no matter whether it is liberal arts or science, or district or city level, as long as Xia Guoxing participates, No. 1 will definitely be his.This little computer programming competition won't make Xia Guoxing a "deserter", right?

It was only later that everyone found out that the culprit behind Xia Guoxing's "fleeing battle" was the "computer"!
Since the winter vacation, Xia Guoxing has been on the Internet.Xia Guoxing has gained a lot from the Internet, but because of spending too much time online, his eyesight has dropped significantly.After the winter vacation, his original pair of glasses no longer worked, so he had to get a new pair of glasses. The thickness of the lenses was also increased, almost becoming a "bottom of a wine bottle".

After the school started, the school received the notice of the computer programming competition in the district, and directly gave one of the places to Xia Guoxing.The head teacher repeatedly told Xia Guoxing: Prepare well and strive to win another trophy for the school.Now Xia Guoxing became more "reasonable" when surfing the Internet. As soon as his mother advised him to rest for a while, he said, "The teacher asked him to prepare well."

Every day after school, Xia Guoxing got into his hut and lay motionless in front of the computer.Sometimes it is to prepare for the game, and more often it is to chat and browse information online.For several nights in a row, Xia Guoxing didn't go to bed until near dawn.The day before the competition, the teacher told Xia Guoxing that he must rest early today and never look at the computer again.But Xia Guoxing couldn't control himself, so he stayed up all night again!

Early the next morning, his mother called him to eat, only to find that Xia Guoxing had fallen asleep in front of the computer.Mother was angry and distressed.Xia Guoxing drank a few sips of milk before rushing to the competition venue.

The game was going on intensely, but Xia Guoxing had difficulty concentrating. He only felt dizzy, nauseated when he looked at the computer, and his eyes were blurred.So, he wanted to stand up and apply to the teacher to wash his face.But as soon as he got up, he fell to the ground.Xia Guoxing withdrew from the competition.

Xia Guoxing was sent to the hospital.

The doctor told Xia Guoxing's mother that the main reason for her fainting was that she worked too long in front of the computer and overused her eyes.Working in front of a computer screen for a long time will not only affect people's eyesight, but also change brain waves, which will have adverse effects on one's body.

Xia Guoxing asked, "Why?"

The doctor told him: If he spends too much time on the computer, the microwave radiation of the computer will form two kinds of harmful brain waves, one is sleep brain waves, and the other is rapid sawtooth brain waves, both of which will make people lose their ability to judge. , It is easy to make people suffer from dementia, and it is even more harmful to minors.

After being discharged from the hospital, Xia Guoxing moved the computer out of his cabin.He said he would never be online again, day and night, as he used to.
