Chapter 015: Anti-Virus (3rd Update)
Xia Jiuying's home is at No. 8 Hongqi Road, and the old Nanzhou people generally have three points of awe for this place, because this is where the leaders of the Nanzhou Municipal Government live, Xia Jiuying lives in Nanzhou with her mother, her mother's name is Zhang Chunli, the deputy mayor of Nanzhou City, and the first deputy mayor of Nanzhou City, so at the beginning of his tenure, he was divided into a house here.
These were introduced by Xia Jiuying on the road, because she is usually very low-key at school, except for a few very good classmates in the class, as well as the school leaders of the school, and the head teacher know her identity, other classmates, and even ordinary teachers don't know that this gentle girl, who is known as the first school flower of Nanzhou No. 1 High School, has such an amazing background, of course, these are not secrets to the reborn Xiao Yuan, but Xia Jiuying can say it in person, which makes him feel very comfortable.
Following Xia Jiuying into the house, Xiao Yuan looked around, he was a human being in his past and present lives, and he was the first time he came to the house of a high-ranking municipal official, so he was very curious.
Xia Jiuying's home is not big, the house type is a three-bedroom, about 8-90 square meters, the decoration of the house is not as luxurious as Xiao Yuan imagined, compared to his mother's villa in Jiangzhou, it can only be described as simple.
"Isn't it disappointing?" Xia Jiuying said with a smile when she saw Xiao Yuan looking around.
"It's very cozy, more comfortable than those big houses that are decorated." Xiao Yuan was heartfelt.
Xia Jiuying took Xiao Yuan to the bathroom to wash the sweat stains on his face, and after a short rest in the living room, he took him to the room where the computer was placed.
Xiao Yuan sat down next to the computer, and Xia Jiuying made a stool and sat down next to him.
A burst of girlish fragrance hit, Xiao Yuan's heartbeat couldn't help but speed up a little, and he couldn't help but turn his head to take a look.
"I'll help you turn it on." Xia Jiuying said, bending down to turn on the machine, and at this time, Xiao Yuan turned his head and was condescending, his eyes entered from Xia Jiuying's neckline, and he saw a touch of spring.
"Shhh Xiao Yuan gasped, and quickly turned his head, his heart was beating violently, and a tight glance at it made his mouth a little dry and his blood surged.
Di, after the computer self-check, the sound of normal boot summoned him back from the state of soul travel, Xia Jiuying's computer is not the latest, it is still running windows95, which makes Xiao Yuan a little surprised, in his mind, the computer of the deputy mayor's house should be very advanced.
"I usually use this computer to check some information, this computer is mainly used by my mother, the computer has a problem these days, and she is too busy to repair it, so I took the liberty to call you over." While waiting for the computer to start, Xia Jiuying explained, and at the same time turned on the cat used to connect to the Internet on the computer desk.
Soon the computer booted up, entered the desktop, a dial-up connection window popped up, and then the automatic dial-up, in the squeaky dialing sound of the kitten, connected to the network.
"Does your computer usually dial auto-dial?" Xiao Yuan asked.
"Yes, it's more convenient that way, once I accidentally disconnected the network once, and the computer froze, and from then on, I found out that there was something wrong with the computer." Xia Jiuying said.
"Well, I'll try, by the way, have you killed the poison?"
Xiao Yuan noticed that there was a popular antivirus software running on the computer, so he asked, and at the same time he decided to try what happened when Xia Jiuying said that the network was broken and crashed, and he clicked the mouse twice to disconnect the network.
"I did, but the antivirus didn't find any viruses." Xia Jiuying said.
"Hmm." Xiao Yuan nodded and didn't ask again, because at this time, the computer had a blue screen of death, and the prompt message given was that the computer had a fatal error, please restart the computer.
Xiao Yuan didn't get anything useful from the blue screen information, so he could only restart the computer and let the network connect automatically again, so as to ensure that the computer did not crash first.
He opened the task manager and looked at the processes running in it, the so-called process, is all the running programs in the computer, including the foreground program that can see the window, and there are more background programs that run quietly in the background without windows, if the computer is infected with viruses or Trojans, then it is likely to find their shadows in the list of processes in the task manager.
Carefully probing the list of task manager processes, Xiao Yuan soon found a very suspicious process in it, the name of this process is very similar to a certain system process, only one letter is missing, inexperienced people are afraid that it will be easy to be confused by the name of the process, of course, this simple trick can not escape Xiao Yuan's eyes, he wrote down the name of this process, and soon found the file that generated this process in the system folder.
"Xia Jiuying, now it's certain that your computer is poisoned, and this program is a virus." Xiao Yuan pointed to the file he found on the computer screen and said.
"But why can't the antivirus software find it?" Xia Jiuying asked puzzled.
"Today's antivirus software is not very smart, and if it doesn't have the signature code of the virus in its virus database, it will think that the computer does not have a virus." Xiao Yuan explained, at the same time, he ended the virus process in the task manager, changed the name of the virus file in the system folder, deleted the suffix exe, and then copied the file outside the system folder.
After doing this, Xiao Yuan disconnected from the network, and sure enough, he didn't crash again.
"Is that all right?" Xia Jiuying saw that the computer was no longer dead, and immediately asked happily.
"Can't be too early to rejoice, let's restart the computer and try." Xiao Yuan was not as optimistic as Xia Jiuying, he restarted the computer again, and soon the computer was started again, and the dial-up was connected to the network.
Xiao Yuan opened the task manager again, checked the process list, and sure enough, found the process he deleted just now.
"See, this process is not the root, there must be a deeper virus program hidden in the system, this program will automatically copy this process to the system folder, and then run it, just now we deleted one, it found it, so it copied in another oneγ Xiao Yuan patiently explained to Xia Jiuying that he was not a person who liked to talk too much, but in the face of Xia Jiuying, he couldn't help but want to say a few more words.
"This virus is so powerful!" Xia Jiuying screamed in surprise.
Xiao Yuan smiled slightly, for Xia Jiuying, this virus is very powerful, but for Xiao Yuan, this virus can only be regarded as a little trivial, there are many viruses and Trojans that are more powerful than this, he has seen too much, and now he is interested in what is the real purpose of this virus after it is stationed in this computer, he doesn't believe that the person who wrote this virus forced Xia Jiuying's computer to connect to the Internet, just for fun.
Of course, the first thing he has to do now is to find out the real root cause of this virus, and then talk to Xia Jiuying about the deeper things hidden behind this virus.
