After sighing, Zhang Lifei checked Sinan's computer, and sure enough, there was no response when he pressed the power supply, the monitor was fine, it seemed that the problem was on the host, he opened the side panel of the case, and couldn't help but shake his head and sigh: "It's too ruined machine." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info" Sinan stretched out his head to look in, only to see that the motherboard memory hard disk was covered with thick ash, he asked Sinan if there was a vacuum cleaner at home, Sinan said yes, took it out of the closet and connected the power supply, Zhang Lifei cleaned it, and plugged all the power plugs back and forth again, only then did he see clearly that the accessories inside were all high-end good brands, but unfortunately the owner didn't care enough for them.

After trimming, turn on the machine again, this time the machine reacted, Zhang Lifei knocked on the keyboard, the feeling was condensed, he turned the keyboard upside down and put it on the table, gently patted the bottom plate of the keyboard with his hand, and then took it away, Sinan blushed, the soot snack dregs that fell from the gap in the keyboard on this table were really embarrassing.

Zhang Lifei said with a little seriousness: "This is not a good habit, which affects the performance and service life of the machine. Sinan whispered yes, quickly took a rag and wiped the desktop clean, destroying the embarrassing scene.

When he entered the system, Zhang Lifei's ten fingers flew on the keyboard like a rain after a swarm of dragonflies dotted the water, and Si Nan, who saw it, also admired, there are masters in each line. Zhang Lifei entered the field he was good at, no longer a shy quail, his brows furrowed slightly, he was engrossed, exuding the confidence and authoritative aura of a professional powerhouse, and briefly explained to Sinan while tinkering: "There are too many junk files, you must clean them up regularly, otherwise the speed will be slow...... Don't use the default browser.,I'll install a professional browser for you.,Safe and stable, you can get over the wall and translate...... Hmm, you have to patch it in time, especially the system bug patch, otherwise the loss will be great...... This machine is all filled with family buckets, and I'm going to delete some ......."

Si Nan can understand it, but he only thinks that under Zhang Lifei's training, the computer is as well-behaved as a docile golden retriever. When the tinkering was almost done, Zhang Lifei turned his head and asked Sinan: "Shall I install a gadget developed by myself for you?" Remotely assisted. The client is here, and the connected server is on my own server, so that when the machine has a problem, if you can enter the interface after startup, you can restore the system here with one click; If the machine is broken enough to stay on the first screen of the boot, you can also find the operation button instructions at the bottom of the screen, or just click it. I made a system backup on your hard drive, and if you don't have an internet connection, you can restore it locally, but it may make some relatively new files disappear. ”

Sinan asked with a little suspicion: "Isn't that just a Trojan horse?" ”

Zhang Lifei smiled: "It's okay to explain it like this." But the initiation is yours, that is, if you don't initiate a request for help, my server will not be able to connect or get any messages from your machine. After all, it's not a program that runs actively or resides in the background, it's just a gadget. ”

After cleaning up, before Zhang Lifei got up to say goodbye, he said to Sinan: "I want to lead the team to participate in the competition during this time, if the phone is not connected, send me an email." ”

"What game? Coding Contest? ”

"It's not. It is the MS Corporation's World Safety Contest. See which team can find and fix the system vulnerabilities they have reserved the fastest. The world's top white hat contest has a small prize money, only 100,000 US dollars, but it is the Nobel Prize in the Internet security industry. Zhang Lifei's eyes shone with a fighting spirit that was determined to win.

"That...... What is White Hat? ”

"Well, it's good that you understand it as a righteous hacker. We mainly find vulnerabilities and inform enterprises in a timely manner, and remind everyone through the global white hat alliance to fix them as soon as possible to avoid greater losses, and I am also a special expert of the network information technology security team of the Ministry of Public Security - so I am a righteous man, and I will not do anything unsightly on your computer. ”
