Compared to making cakes together, although the benefits of turning over the table are great, the risks are also great. Moreover, there is also a table to turn over.

From the outbreak of the millennium to March of the millennium, the antivirus software market has almost equaled US$5 million per year from the end of the 20th century, and has suddenly changed several times, and is expected to reach US$200 million.

It was so rare before, because the network was relatively safe. Unless it was a user with special needs for security, the rest basically didn’t have to worry about being shot in their computers.

But since the millennium passed, the virus spreading on the Internet has suddenly become popular.

And don't think that a computer will survive if it is not connected to the network.

No, no.

Viruses can infect floppy disks, and even directly burn the virus onto the CD when burning the CD.

If you accidentally use floppy disks and CDs infected with the virus, even if a computer that is not connected to the network, it will be infected with the virus and various problems will occur.

The types of these viruses are mainly divided into several types, one is a worm virus that is almost purely for infecting my purpose.

This virus spreads very quickly, just like a computer's influenza.

Another type is the Trojan virus.

Although this virus has a slightly less destructive power, it is more hidden. Moreover, the purpose of its transmission is no longer simply destruction, but premeditated stealing of user information.

But no matter which virus is, it is very deadly for computer users.

In order to avoid being shot, you can only spend money to buy antivirus software.

Of course, although antivirus software is amazing, it cannot solve all problems in the first time.

As we all know, the so-called computer virus is also a program.

And as long as it is a program, it must have its own rules and characteristics.

The reason why antivirus software can be used to identify the feature code is to identify the pattern.

Once you confirm that a certain program has a pre-set feature code, then kill it.

However, technology always spirals up.

After the antivirus software comes out, those viruses will no longer sound? No, no.

The old viruses are constantly mutating, while new viruses are constantly emerging.

Whether it is a new virus or an old virus, its occultness is becoming stronger.

For example, a virus that could have been easily detected has now imitated a key process of a system that has been set to a whitelist.

The reason why it is set to a whitelist is that the system will crash as long as this process is deleted by mistake.

The virus disguised as this program, just like a fake and shoddy product with an inspection-free logo.

Faced with such a new situation, the antivirus software needs to update the virus database and formulate a new response strategy for this virus.

Most programmers in antivirus software companies face every day, which is to constantly analyze viruses, extract feature codes, and then update the virus database.

However, although this is a little troublesome, it still has many benefits for antivirus software companies.

What are the benefits?

It is that antivirus software can be sold continuously.

You should know that there is no limit on the usage period for software purchases nowadays.

In other words, after buying, you can use the activation code to activate it when you go back and use it all the time.

The same is true for antivirus software.

If this is the case, if there is antivirus software on every computer, there will be no business.

Therefore, antivirus software must be turned into a product with a deadline.

The constant emergence of viruses puts pressure on computer users.

Although the antivirus software can be used all the time after buying it once, the update time of the virus database is limited.

For example, when you first start buying antivirus software and sell the main body, you will "attach" a virus database annual fee activation card. In this way, the virus database can be used for one year.

After a year, the update of the virus database entered for the "attached" service will end. At this time, you have to spend about two-thirds of the original body to specifically purchase this annual card.

Of course, the antivirus software market has only been booming for a few months now.

However, these antivirus software companies have already thought of an excellent business model. This business model cannot be said to be invincible, but it is a good way to make money.

However, the free security software company founded by Tom, called Free Security Software, puts these companies under pressure.

First, because of this company, a large number of excellent programmers have left, but because if this software is really launched, it will be a great destruction to the payment standards that have been finally established.

However, it will take at least several months to become a finished product.

Therefore, in the past few months, paid security software companies have begun to launch public opinion wars, first making consumers think that even if there is free security software, it will not be easy to use.

They even deliberately supported a free security software company.

This company does not sell physical versions of antivirus software. Because it is free, it cannot make money in stores and channels. Of course, there will be no physical version.

It's a bit just a download version, and the average network speed in the United States at this time was only about half a megabyte.

The antivirus software and its supporting virus recognition library are at least about 100 megabytes. Therefore, it will take at least several hours to download this software.

Moreover, due to the download speed of a large number of users simultaneously, the download speed will also slow down.

Finally, even after going through a lot of hard work, the ability of this free antivirus software cannot even be described as unsatisfactory, but can only be said to be artificial intelligence retarded.

These companies' own free antivirus is also obvious.

They cannot escape from existing interests, so they must denigrate another new interest that threatens them.

But if you say something bad is not good, it is not good, and there will not be many people who believe it. However, seeing is true, but only after using it, it is within the scope of most people's understanding.

So they built a free antivirus software themselves, and then made the antivirus software very bad and vigorously promoted it.

In this way, people who have used this free security software will lose confidence in the free antivirus software.

The truth of "recognizing that there is no good thing for free, and only by spending real money to purchase services is the hard truth."

With mature antivirus software products, they naturally achieved twice the result with half the effort when they acted. They quickly made antivirus software, and also included related website homepages, and began to place targeted advertisements on search engines.
