Many people regard anti-virus technology as mysterious. In fact, no matter how the anti-virus software T is upgraded or the concept changes, the basic principle is the anti-virus engine plus virus signature matching. "Han Chu explained to Fan Ting while drinking tea, "Simply understand that the anti-virus engine is a gun, and the signature is a bullet. The more bullets, the more viruses it can kill. Many people use pirated anti-virus software. The reason for the poor effect is that pirated anti-virus software cannot upgrade the special database, and if the signature database cannot be upgraded, the new virus cannot be dealt with. "

Fan Ting finally figured out the working principle of anti-virus software. Although she and Han Chu are alumni, they are not in the same major. Therefore, the understanding of computers is mainly in terms of price and performance parameters. As for people use it in the end. What you do here is not very concerned.

But after Han Chu told her for a long time, she finally figured out one thing, that is, anti-virus software needs to be updated and upgraded regularly, otherwise it will not have a good effect on preventing viruses.

"So, is the focus of our work, guns or bullets?" Fan Ting asked.

"Of course it's a gun. The bullet is universal." Han Chu said with a smile.

The signature database of anti-virus software is composed of signature codes of virus samples collected by anti-virus manufacturers, and signature codes are the differences between virus analysis engineers and legitimate software found by virus analysis engineers, intercepting a program similar to searching for keywords Code.

Whenever the antivirus engine scans the hard disk or monitors the action of a file, it will read the file and match all the signatures in the signature database. If the program code of the current file is hit by a keyword, it will judge that file as a virus .

"In general, the work flow of anti-virus software is to collect virus samples through user reports or shared resources of manufacturers, then virus analysis engineers intercept the signatures, and then add the signatures to the signature database to allow users to upgrade the signature database." Han Chu said to Fan Ting, “In this process, the upgrade is too troublesome. Of course, we can let the branch offices take on the task of deploying the feature database, but this is time-consuming and labor-intensive, and the effect is not good. I have a The idea I want to propose to the company is to set up a large-scale anti-virus server everywhere to provide free virus checking and killing and virus signature database upgrade interfaces."

Signature database matching is a very effective technology for checking and killing known viruses, and it is also the basis for the work of antivirus engines. Numerous anti-virus efforts at home and abroad have made great efforts to intercept virus signatures. All signatures require strict testing and testing. Compare, otherwise it is easy to cause accidental injury.

Now that the window operating system is just right, viruses have also begun to evolve, showing a trend of diversification, such as polymorphic ghosts, generators, variant machines, network worms, etc., simply extracting signatures can no longer cope with There are many kinds of viruses, and a more complex broad-spectrum signature appears. In this case, the technology and experience of virus analysis engineers become the decisive factor for the performance of anti-virus software.

Domestic anti-virus software manufacturers are mainly those of the Ministry of Public Security and kV series software. These anti-virus software are small in scale and have fewer researchers. Many of them are developed by a few people. Naturally, they are unable to handle the increasingly complex computer virus environment.

Fan Wubing leads the thinking in the anti-virus software industry. It is to use the number of people and the advantages of advanced technology and equipment to make up for these shortcomings. Make a large and comprehensive anti-virus software. In order to expand their influence in the software industry. This opportunity. Enter other professional software markets.

And Han Chu also deeply understood Fan Wuyi's intentions. So I hope to win over more loyal users through this method. After all, the mainland network has not yet taken shape. It is still difficult to realize the idea of ​​using the Internet to update the virus database. I had no choice but to retreat. Use your local sales network to do this.

"This kind of thing. It's better for you to talk to Wuyi." Fan Ting knows about these things. The old brother Fan's opinion is much higher. I really can't grasp a clear direction. Naturally it will not be a big deal.

Two people only appeared at this time. Fan Wubing seems to have disappeared long ago. The two sat in the same room for more than half an hour.

Fan Ting scratched his head. Suddenly, it seemed that Han Chu was indeed quite good. At least I won't bore myself. It's hard to imagine that I have talked to him about boring technical issues for so long. It's really strange.

And Han Chu also had some feelings. It seems that Fan Ting has not changed much from when he was an alumnus before. Nor has he become his own boss because he is now. Controlling large companies worth billions to tens of billions is domineering. At least at home. She is still very gentle. and. She took the initiative to pour herself several cups of tea tonight!

The two people guessed at each other in a guilty way, and Fan Wuyao took a bottle of red wine and sat on the top of the building.

The air quality in Beijing is still very poor, probably because construction has been underway around the city.

Pollution dust obscures the sky, making it difficult to see the stars in the night sky, even if they are blurred.

Fan Wubing was lying on the recliner, looking at the sky, occasionally taking a sip of red wine, and being gently blown by the night wind, it was also very pleasant.

After a while, my mother Zhang Mei brought a tray to Fan Wuyao, and then said to him, "Don't just drink, eat some food."

Fan Wuyao jumped up, pulled out a chair for his mother, then put the dishes on the table, and said with a smile, "Drinking some red wine for beauty and beauty is good for the cardiovascular system. As long as you are not drunk, it is still very good. of."

Zhang Mei didn't refuse the red wine that her son poured out. She took a sip, then frowned worriedly and said, "Do you think there is a play between your sister and Han Chu?"

Fan Wubing smiled, stretched out his wrist, took a look at the time on the couple watch he bought with Shen Ying, and then said, "It's been an hour. I've been out of the room for an hour. Do you think, Will they have anything to do?"

Hearing this, Zhang Mei almost squirted out the drink he had just put in his mouth, knocked Fan Wuyao's head with chopsticks, and then laughed and cursed, "You kid, you're so speechless! What's in your mind? ?!"

"It's not fried noodles anyway, haha." Fan Wuyao smiled.

However, no matter what happened to the two people, starting from the next day, the relationship between the two people seemed to be a little different from usual. Fan Ting seemed to feel good on her face, and they were planning the launch of the new software together.

Before launching his new anti-virus software, Fan Wubing did a market survey, mainly for the old customers of the club. According to the service record, almost 90% of the customers have experienced being Viruses are raging. Many technical support staff are dealing with the after-effects of the virus when they are out of service.

In this case, it has caused a great waste of resources. The staff often need to waste their own technical resources to deal with some less professional problems, and there may be many more important technical problems to be solved elsewhere. Human resources Lack has caused many staff in the club to be busy. Although the company has given everyone good benefits, the rest time is consumed in large quantities, which is very detrimental to the physical health of the staff.

Therefore, when Han Chu and Fan Wubing proposed his new idea, Fan Wubing immediately decided and immediately added a large-scale virus signature database server, and launched the project in various branches across the country at the same time, in line with the upcoming construction in the capital cities of the country. Optical cable network, establish a dedicated anti-virus server network system.

In this way, qualified customers everywhere can enjoy the company’s anti-virus service for free. After the product’s service life expires, they can continue to spend a small price to enjoy long-term service. This service is guaranteed and safe. , Trustworthy.

After a few days, a large number of newly launched "Pili Beibei" anti-virus suits began to appear in Zhongguancun, Beijing. It was a very thick box with not only CDs and floppy disks, but also encryption programs, which ensured the anti-piracy work. The reliable progress.

In addition to the software, the company also provides customers with a tool disc containing many excellent foreign shareware. Moreover, each sales outlet sells a set of "Pili Beibei" anti-virus kits, there is a certain percentage Commission, which promotes their enthusiasm for work. Whenever they encounter installed customers, they strongly recommend this new anti-virus suit~www.wuxiaspot.com~ In the manual, the "Pili Beibei" antivirus is pointed out step by step with pictures and texts. The method of using the suit is basically according to the diagram. As long as you can turn on the computer, you can perform anti-virus operations according to the instructions, which is very convenient.

At the same time, the sales outlets also randomly presented Microsoft's version. This is the version used in Microsoft's internal testing. The official version has not yet appeared on the market. The new operating system has not been popular in China's 6 regions. When it arrives, it is also carved into a CD-ROM and presented as a random gift, which has brought good news to the majority of computer hobbyists.

How much should I buy for such an anti-virus suit? Fan Wubing gave a very fair price, fifty yuan.

Customers who can spend 10,000 yuan to buy a set of computers will not be stingy with fifty yuan to buy a set of anti-virus software packages that can ensure the safety of their software, and they can also enjoy the club’s latest virus database. The upgrade service is really worth it.

Under such circumstances, Fan Wuyao's anti-virus software has become popular throughout China and is selling well.
