Read the world's strongest soft engine QVM in one minute

Recently, the domestic security circle again came a good news: international authoritative evaluation agency AV-TEST published the latest anti-virus software rankings show, the qvm ai Anti-Virus engine independently developed by 360 companies in China ranks No. 1 in the world with a perfect score of 18. This is the first time that anti-virus software in Asia has obtained a full score in international evaluation. This means that China's independent innovation technology to kill soft is far ahead and has been widely recognized by the international community.

What is QVM? How powerful is it? What benefits can we bring to our lives? Let's take a look at the following articles.

I. What are the excellent anti-virus engine standards?

Before getting started, let's take a look at the criteria for measuring the merits of a antivirus engine:

(1) Trojan and virus detection rate and anti-virus capability. (First, it is "medicine", not "placebo ")

(2) false positive rate of "normal" files. (The side effects of "medicine" should be small, and the user will be less disturbed)

(3) engine performance-including speed, hardware consumption, and O & M costs. (No matter what hardware you want to purchase)

2. What is QVM?

The qvm ai engine is short for Qihoo Support Vector Machine (Qihoo Support Vector Machine. It is the third generation engine (an engine with proprietary intellectual property rights in China) fully independently developed by 360 ).

It uses artificial intelligence algorithms-support vector machines (SVM) and has the "self-learning and self-evolution" capabilities. It can be immune to more than 90% of Shell and variant viruses without frequently upgrading feature libraries, not only is detection and removal far ahead, but it has fundamentally overcome the technical difficulties of the previous two generations of anti-virus engines, "new viruses cannot be killed without upgrading the virus Database", and is the first in the world.

Iii. What is the principle of QVM?

In order to identify viruses, anti-virus techniques are constantly improved, from initial simple signatures to composite signatures, broad-spectrum signatures, to virtual inspiration, to behavior determination. Today, let's jump out of these constraints and fundamentally think about how to distinguish virus files from normal files?

I think there is only one essence of the answer: difference, that is, difference and difference. Virus files can be identified only by detecting the difference of virus files and normal files. On this basis, whether it is a signature, an inspiration, or an action, it is essentially identifying the difference: the difference in the behavior of virus files and normal files, and the difference in file code.

Since it is to identify the differences, can we use some intelligent algorithms widely used by search engines to achieve the goal? The tasks that search engines need to accomplish have many similarities with our anti-virus tasks: 1. Analysis of massive files; 2. Search for specific features.

This is the initial idea and basic principle of QVM. On this basis, QVM has created a unique algorithm similar to the yes' algorithm (an intelligent algorithm that can distinguish normal mail from spam mail, let the engine learn a large number of virus files and normal files on its own, and constantly sum up new data models (that is, MDF files distributed to the client ), finally, model data is used to identify new viruses.

4. What are the advantages of QVM compared with traditional kill software?

Today, 360 is not a traditional security company, and 360 is a security company in the Internet age. He is more Internet-oriented than any other company. QVM was born under such bold ideas. This anti-virus idea and method is definitely the first in the world. Compared with traditional anti-virus software, it has obvious advantages:

(1) strong prospective, high detection rate. The rule of viruses and Trojans can be quickly found, and the detection rate of new virus variants is high. For identified samples, the response cycle is actually "0" seconds (because of the time consumed by the network and hardware, it is generally referred to as "1 second "). In a real environment, the QVM cloud detection rate per second is over 95%. This effect has far exceeded that of other traditional engines and exceeded that of other cloud engines. Even if it is not updated for one month, the QVM detection rate will not decrease by more than 10%, with a six-month half-life. In this AV-TEST test, QVM in the security protection project is also a full score.

(2) Good immunity. It is a traditional method of Eliminating viruses and viruses. Traditional Features, md5, and md5 are matched, which can be quickly located, modified, and toolized. QVM relies on global operations on samples to determine the sample level, which is difficult to locate by virus Trojan authors.

(3) faster speed and smaller size. With such a response speed, real-time identification can be performed. In terms of volume, it can be controlled at around 20 mb now and can be stored locally.

(4) self-learning, low cost and fast response. QVM itself is a decision-making engine that can independently determine viruses without external means. QVM learning is automatic learning, and the cycle is hourly. The broad spectrum is very strong. Once learned, the trojan author enters the painful kill-free cycle. In addition, this engine is deployed on the cloud, allowing you to quickly learn, get online, and participate in detection and removal.

(5) low false positive rate. According to various data feedback, the false positive rate of QVM is much lower than that of other engines. The ratio of false positive to false positive is the highest score compared with other engines. In this AV-TEST evaluation, the false positive rate of QVM is zero.

Now let's go back to the standard of the excellent anti-virus engine we mentioned at the first point. We will know from a comparison that QVM is undoubtedly very good.

Conclusion:

We know that 360 is widely covered in China. According to the company's latest financial report of 360, 360 of the number of users on PC has reached 0.509 billion, and the coverage rate exceeds 96.1%. The QVM engine has completely covered 360 of all users. That is to say, almost every computer in China has benefited a lot from the qvm ai Antivirus Engine independently developed by 360.

This 360 self-developed QVM engine won the championship in the international evaluation, which means that QVM has stepped out of China and rushed to the world. The Anti-Virus engine, represented by 360, has the ability to compete with foreign anti-virus engines and lays the foundation for completely autonomous and controllable security software, the localization process of information security will be accelerated again.
