Compared with making cakes together, although the benefits of flipping the table are great, the risks are also great. Moreover, you also need to have a table to lift it.

From the beginning of the millennium to the March of the millennium, the antivirus software market doubled from almost $5 million a year at the end of the twentieth century to $200 million.

Before, there were so few because the network was relatively secure, unless it was a user with special needs for security, the rest basically didn't have to worry about getting shot on their computer.

But since the turn of the millennium, the virus that has spread on the Internet has suddenly become popular.

And, don't assume that your computer won't survive without a network connection.

No, it won't.

Viruses can infect floppy disks and even burn them directly into the disc when it is burned.

If you accidentally use floppy disks and CDs that are infected with viruses, even if you don't have a computer connected to the Internet, you will be infected with viruses and various problems will occur.

There are several main types of these viruses, one is a worm that is almost purely for the purpose of infecting me.

The virus spreads so quickly that it's like a computer flu.

The other is a Trojan virus.

Although this virus is slightly less destructive, it is more hidden, and the purpose of its spread is no longer simple destruction, but premeditated theft of user information.

But no matter what kind of virus it is, it is very deadly for computer users.

In order to avoid getting shot yourself, you can only spend money on antivirus software.

Of course, antivirus software is very well eaten, but it doesn't solve all problems at the first time.

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

As long as it is a procedure, it must have its laws and characteristics.

The reason why antivirus software can kill viruses is that it uses a pattern that recognizes the signature code.

Once you've made sure that a certain program has a pre-set feature code, kill it.

Technology always spirals, though.

When the antivirus comes out, those viruses won't make a sound anymore? No, it won't.

Old viruses are mutating all the time, and new ones are emerging.

Whether it is a new virus or an old virus, it is becoming more insidious.

For example, a virus that could have been easily detected now mimics a key process of the system that has been set to be whitelisted.

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

And the virus disguises this program, just like a counterfeit product with an inspection-free mark.

In the face of such a new situation, antivirus software needs to update the virus database. Develop a new strategy for this virus.

Most programmers in antivirus software companies are constantly analyzing viruses, extracting signatures, and then updating the virus database.

However, although this is a bit more troublesome, it still has a lot of benefits for antivirus software companies.

What are the benefits?

That is, antivirus software can be sold sustainably.

You know, there is no expiration date for software purchases.

That is to say, after buying, go back and activate it with the activation code, and you can use it forever.

The same goes for antivirus software.

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

Therefore, it is necessary to make antivirus software a product with an expiration date.

And the constant emergence of viruses is a pressure on computer users.

Although you can use antivirus software once you buy it, you can only update a virus database for a limited time.

For example, when you first buy antivirus software and sell the ontology, you will be given an activation card for the annual fee of the virus database. In this way, the virus pool can be used for a year.

After a year, the virus database update entered into the "Included" service will end, and at this time, you will have to spend about two-thirds of the price of the body to buy this kind of annual pass.

Of course, the antivirus 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 is not invincible, but it is a good way to make money.

However, Tom's free security software company called Free Security Software has put pressure on these companies.

One is because of this company, a large number of excellent programmers have left, and because if this software is really launched, it will be a great damage to the payment standard that has been established with great difficulty.

However, it will take at least a few months for this thing to become a finished product.

Therefore, in the past few months, paid security software companies have begun to wage a public opinion war, first making consumers think that even free security software will not be easy to use.

They even went out of their way to prop up a free security software company.

This company doesn't sell a physical version of antivirus, because it's free, so stores and channels can't make money, and of course there won't be a physical version.

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

The minimum size of the antivirus software and its supporting virus identification database is about 100 megabytes. So, to download the software, it will take at least a few hours.

And, due to a large number of users downloading at the same time, it will also cause a slowdown in the download speed.

In the end, even after a lot of hard work, the capabilities of this free antivirus software can't even be described as unsatisfactory, it can only be described as artificial retardation.

The intention of these companies to engage in free anti-virus on their own is also obvious.

They cannot break away from existing interests, so they must denigrate a new kind of interest that threatens them.

But if one thing is not good, it is not good, and there will not be many people who believe it. But seeing is believing, and knowing only after using it is within the scope of most people's understanding.

So they made a free antivirus software on their own, and then they made it suck and promoted it vigorously.

As a result, people who have used this free security software will lose confidence in the free antivirus.

The truth of "recognizing that there is no good thing for free, and that only spending real money to buy a service is the last word".

With mature antivirus software products, they naturally get twice the result with half the effort, and quickly produce antivirus software, and also match it with relevant website homepages, and begin to target ads on search engines.

For example, when you search for keywords such as "virus" and "free antivirus", the official website of this antivirus software will appear at the top.
