After knowing what the virus was, Qi Yan began to think of a way to solve it. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

There were now three paths ahead of her.

For this type of memory virus, it can be destroyed immediately by unplugging the network cable, but it cannot prevent it from being infected by the virus again. Just now, Qi Yan unplugged the network cable and restarted the computer, but as soon as he turned on the network, he was immediately infected again, pass!

You can also unplug the network cable first, and then patch the system accordingly, so that viruses cannot enter the system.

Either that, it's blocked with a personal firewall. This approach requires an understanding of the vulnerabilities and ports used by the virus, and then setting security rules in the firewall so that the virus cannot spread through the vulnerability.

Qi Yan chose the latter of the two methods, although it was a bit time-consuming, but once and for all.

Unplugged the network cable, Qi Yan began to check the computer documents, modify the firewall, and was busy for an hour to get it right.

Plug in the network cable, connect to the Internet, open the web page, and it is ready to use. Log on to QQ, and you will find that there are four messages to add friends.

Qi Yan nodded over and agreed one by one, three of them were roommates, and the other was named Youyou, but he didn't know who it was.

Just when Qi Yan was about to enter the QD website to check the novel he had written, a pop-up box appeared.

"Qi Yan!?Are you online?" is Wang Ran, the first person to buy Qi Yan's website.

"Yes, it's just online, what's wrong?"

"You're using a computer right now?"

"Uh-huh!" Qi Yan typed out two words.

"Oh my God, where do you use your computer?"

"In the dormitory!"

“……”

"Which city?"

Qi Yan seemed to feel the other party's resentment, and hurriedly typed over, "In City B." ”

“！！！”

Three exclamation points came from the other party's message.

“？？？”

Qi Yan didn't know why.

"The network in City B can still be used?!! I just contacted a friend over there, and said that the network has been paralyzed!!"

Wang Ran looked at the message sent by Qi Yan in disbelief. Originally, he thought that Qi Yan was in a relatively remote place, and it was normal for the Internet to be used, but he didn't expect her to be in the capital, which was incomprehensible.

After all, an unknown virus broke out in various major cities in China early this morning, and it is extremely transmissible, and now their company's servers have been paralyzed, and personal computers are saying goodbye. He can only use his mobile phone to make calls or log on to QQ if he wants contacts.

"No, I couldn't access the Internet at first, but then I modified the firewall and it worked. ”

“！！！”

Wang Ran was shocked when he saw this, he knew that Qi Yan's computer skills were good, which could be seen from the website she made, but he didn't expect her to have this ability.

"At seven o'clock this morning, the network of well-known cities across the country was paralyzed, servers could not work, personal computers could not access the Internet, and even information on large websites was stolen, especially the networks of cities B, S, and G provinces have basically been recruited. ”

"Oh, it's so serious!"

Only then did Qi Yan realize the seriousness of the incident, if he didn't solve it quickly, he was afraid that he would suffer huge losses.

"Is there anything I can help me with?"

"Yes, our company is a network technology company, and we are the first to bear the brunt, and now the company's technical staff have joined forces with other companies to find a way, but there is no progress yet. Wang Ran hurriedly typed.

"I don't know the characteristics of your company's firewall, so I can't help you solve it directly, but I can tell you the characteristics of the virus that attacked the network this time. ”

"Yes, I will find someone to come and communicate with you, it's great, don't worry, our company will never let you help in vain!" Wang Ran finally did not forget to promise benefits.

"You're welcome!"
