In general, domestic anti-virus software is very bad. Please read this article.

It is impossible to avoid being infected 100%. In addition to security software, security habits are also very important.

Want me to recommend? What I like may not be suitable for you.

Let me show you my articles and choose for yourself.

I have been in the Kafan forum for a while, and I think I know a lot about anti-software. According to my experience, antivirus software is not omnipotent and cannot detect all viruses. Killing software will not be the best. Many anti-virus software are very good. Each anti-software has its own characteristics, advantages and disadvantages, and advantages and disadvantages. In short, security awareness and computer knowledge are the most important, and to be safe, you should install anti-virus software, firewalls, HIPS (intelligent hips for newbies), and sandboxes. (It’s a bit much... In fact, if you have good safety habits, you don’t need to use so many, it’s too tiring.) In addition, hips actually save resources than using hoses. . . Of course, poison can overcome him. In addition, you can also try virtual machines, hard disk recovery cards, shadow systems, etc. However, there are also viruses that can pass through them, so security software is still necessary. Also, if you want to learn about anti-software, please go to the professional anti-software forum (the Kafan Forum is recommended). Many articles on the Internet are either wrong, inaccurate, or out of date. (For example, the misleading article by the 5 major engines states that antivirus engines are the core of antivirus software, so many antivirus software are their own engines! And many engines are very good!) Don’t believe the reviews and rankings of antivirus software on the Internet. . Even the evaluations of authoritative organizations such as VB, AV-c, and AV-test are only things in the laboratory, just for reference, and their testing methods are not without problems. And basically every test result ranking is different. That toptenreview is nothing more than a price/performance ranking (that is, the one with bitdefander first). Therefore, anti-software is not ranked at all! ! No one dares to line up and look for scolding. . .

Most people like anti-virus software with high detection rates (actually very boring). There are currently 6 of them:

1. Kabbah (Russian anti-software): Needless to say, Kabbah , super strong, the previous detection rate was super high, Dugu Qiubai! Now because there are more free kills against him, the detection rate is lower than before. Dr. Kaspersky and Dr. Solomon made significant contributions to early anti-software. The two anti-virus engines they made are highly praised. Kabbah's engine is used by many anti-virus software. Solomon was once the largest anti-virus company in Europe, and was later acquired by McCafé. Now McCafé uses soloman's engine. Back to Kabbah, KIS (Kaba's Internet security suite) has antivirus, firewall, hips, sandbox, etc., and they are all great and rare! Three-dimensional defense is great! Because you have hips, you don’t have to be too afraid even if there are many free-for-alls. However, the new version 2010 takes up a lot of resources, although there are actually several older versions that are quite small. . . Because there are many free kills, the detection rate can only be ranked lowest among these 6. . . The others are too strong. . . However, it is not easy to maintain a high level with so many free kills. . There are keys everywhere on the Internet, so it is no different from free anti-virus software.

2. Little Red Umbrella (avira antivir, German antivirus software): There is a free version, small resource usage, very low false alarms, not as high as anyone said, super high detection rate, and sensitive monitoring , The scanning speed is extremely fast, and the heuristic virus checking is very good! It is one of the best heuristics among anti-virus software. There are best static heuristics. It can detect unknown poisons very well. Of course, hips can also detect unknown poisons, which is even better. It's a pity that Red Umbrella doesn't have hips yet, but it is said that it will soon. Red Umbrella is only available in English. . . . But that bit of English is not difficult. And there is a Chinese version online. Xiaohongsan + comodo's firewall and hips is a very classic combination, known as the red bean combination, and it's completely free! But some people may not be used to comodo. You can also use other firewalls and HIPS. Many good firewalls and HIPS are free.

3. G data AVK (German anti-virus software): avast! , bitdefander dual engines, the natural detection rate is super high. In addition, avk2006 uses Kabbah and bitdefander engines, which is even better than the new version. . . Very popular.

4. Trustport (Czech anti-virus software): 10 engine monsters, 5 purchased, 5 own small engines. The natural detection rate is super high, but the resource usage is super large, and there seems to be some problems with the coordination between the 5 engines. . .

(Don’t be superstitious about multi-engines. The detection rate may not be higher than that of a single engine, and it takes up a lot of resources. However, there seem to be more and more multi-engine anti-virus software.)

5. Ikarus (Austrian anti-virus software) ): Slightly higher false positives, takes up a lot of resources, can only check virus signatures, has no heuristics, and is not good for new viruses. There are many shortcomings. . But - the detection rate is super high. . .

6. a-squared (Austria): OEM of Ikarus, plus its own engine. There is a free version, but the free version can only scan and has no monitoring. The anti-malware version also adds its own smart hips, mamutu. great! But beware of false positives.

Each has its own characteristics, choose for yourself, and the domestically produced Feltoost is also great. As for other anti-virus software, especially well-known foreign anti-virus software (such as Norton, nod32, AVG, avast, bitdefander, F-Secure), the detection rate is not much different from them. (By the way, F-Secure is also a multi-engine anti-virus software. It mainly uses the purchased engine, supplemented by a few small engines of your own or purchased. The detection rate is very good. I bought an old Kabbah engine before, (the latest The engine will not be sold), now it uses BitDefender because it can’t afford Kabbah. )

Let’s list some good anti-virus ones, that is, the real-time scanning detection rate is good and the monitoring is tight. , comprehensive, in place, and preferably with hips or custom rules. (Most of the software antivirus software is smart hips)

The big software antivirus companies and those who do enterprise antivirus are: Norton (the enterprise version is Symantec, and Norton is now taking up a lot of resources. It’s too low), McCafé (you can set your own rules like hips and you have hips), trend, CA, sophos, etc. In addition, the defense of home anti-virus tools such as Kabbah, panda, F-secure, etc. is also very good (and also very large companies).

In addition, the domestic Oriental Microdot is also very good, but I think it is not an anti-virus software, but is essentially a smart hip. The so-called active defense and behavior analysis are actually smart hips, which only alert the police for dangerous behaviors (sequentially calling certain dangerous kernel native APIs), rather than alerting the police if the hip calls dangerous APIs. (Because there are pre-written built-in rules) (hips can manually write rules, and once written, it can be very quiet and safe) (The active defense mentioned above is active defense in a narrow sense, which refers to behavioral analysis. In a broad sense, active defense refers to all types of Virus detection methods that rely on signatures to detect unknown viruses, such as broad-spectrum signatures, heuristic virus detection, and HIPS)

There are also many anti-virus software that are good, but do not have HIPS. In fact, many anti-virus software don't come with them, because hips and firewalls should be installed separately. You can install them yourself and anti-virus software doesn't care. In other words, generally anti-virus software or anti-virus software with a good detection rate is good, as long as its monitoring is strict and comprehensive. As for the hips, you can install professional hips. In addition, more and more anti-virus software are adding HIPS, which seems to be a general trend.

Also, although many software claims to have active defense, it is just a hype concept and not an intelligent HIPS. Although some anti-virus software has intelligent HIPS, its level is poor. Only a few anti-software HIPS can reach the level of professional HIPS.

Let’s list a few more that have official lifetime free versions (free anti-virus software is not bad! In other words, it will lack a few unimportant functions. Many good foreign anti-virus software have long been free for home users. version, and after Microsoft released free anti-virus software, other manufacturers were forced to make anti-software free and reduce prices. Free anti-software seems to be the general trend): avast, Xiaohongsan, avg, a-squard, mse (made by Microsoft, good ), 360 Antivirus, etc. (Amateurs who do antivirus software use bitdefander’s castrated engine and virus library, which is not very good and is not recommended)

Let’s list a few more resources that occupy less resources: avast, Xiaohong Umbrella, nod32 (previous version. The heuristic of nod32 is great! It is the best dynamic heuristic. But other aspects...), MSE, 360 anti-virus, etc.

Let’s list a few more domestic ones : Oriental Micropoint, Feltost Security. Ruixing, Jinshan and Jiangmin should forget it. . . . In addition, the trend is that a person from Taiwan built it in the United States, so it can be considered half domestic.

The trend now is towards large multinational companies, which is amazing and proud. However, I personally think that the anti-virus capabilities are quite average. . . . In addition, CA is very similar to Trend. It is also a large company and was founded by Chinese people in the United States.

Also, don’t worry that anti-virus software is not free. There are registration machines and keys online. . . .

But please protect your intellectual property rights and try to buy genuine copies! ! Research and development of anti-software is very tiring! It’s not easy to kill software companies! They have done a lot for us. . . .

Also, let me clarify some misconceptions:

1. It is rumored that Norton and McCafé have some Microsoft Windows source code. It is not known whether it is true or not, and this cannot be verified. But Microsoft didn't give the source code of Vista to anyone, that's for sure, and the same goes for Windows 7. So now it's the same for both anti-virus and software. In fact, mse definitely has source code. . . . . But having source code doesn't make a big difference. Good compatibility and stability of the system. By the way, whether there is source code has nothing to do with entering the system kernel. Many viruses can enter the system kernel, but they do not have source code.

2. Some anti-virus software is used by the military and the government, but this doesn’t mean anything. The military also has ordinary computers. . . But the computer where secrets are stored and the computer used for command are not PCs, not Windows systems, they are not connected to the Internet, and they do not require anti-virus software! ! What the military and government use to kill software is mostly due to political factors (domestic software must be used) and public relations. (That’s why China mostly uses Rising...Russia uses dr.web, and Kabbah also uses it) Will the computer be unsafe if it is so casual? It's okay. The military has always been very disciplined and doesn't surf the Internet casually. There are experts there, so you won't be afraid. Moreover, their security does not only rely on anti-software, which has limitations. They also use ips, IDS and the like, and have a complete set of defense systems.

Similarly, enterprise anti-virus software is not better than personal anti-virus software. The enterprise version needs to be manageable, well protected, stable, and cannot kill by mistake, so the detection rate is often not high. And it will not use new technologies rashly like the personal version. So many new technologies are not available. . . Of course, companies are not afraid of poisoning. Large companies have strict management and do not allow employees to mess with computers. In addition, they have professional network administrators, so they are not afraid. Similarly, their security does not only rely on anti-software. They also use ips, IDS and the like, and have a complete set of defense systems.

In addition, in fact, many institutions, including governments, use enterprise anti-virus software, at least the enterprise version and online version of anti-virus software, because their situations are very similar to those of enterprises.

3. DR.web (Big Spider) was either developed by the Russian National Academy of Sciences or made by an individual, Dr. Kaspersky’s friend--Igor Daneliov. It has also been commercialized and once accounted for 95% of the Russian market was later surpassed by Kappa. . . DR.web's technology is very good. Igor Daneliov is a well-known genius, but it is not as strong as it is boasted on the Internet. Its shelling function is only average and it can still not detect some strong poisons. Its virus database is a bit small, so the detection rate is not very high, but it is enough, but the scanning is too slow and unbearable. The Russian military can tolerate it and is not afraid of causing trouble? Having mentioned a lot of shortcomings, let’s talk about the advantages. Its recovery ability is very good. If it is poisoned, it can try its best to remove some of the poisons that can be removed, so that the files can be restored, and sometimes the system can be saved. Therefore, its free scanner Dr.web cureit! is highly recommended.

4. It is said that nod32 may have been used by Microsoft for 4 years, but it is only used in some places. Microsoft uses Norton and Coffee more (both are in the United States and have cooperation). Of course, the security of key departments depends on experts within Microsoft. As for the Pentagon using nod32, it is pure nonsense. The US military uses Slovakia to kill software? Crazy?

5. There is a so-called test for killing software monitoring on the Internet, which is to copy a piece of code into Notepad. That test only tests whether the monitoring is activated, and has nothing to do with whether it is good or bad. Some anti-virus software do not monitor Notepad. It is not a program, will not be executed, and will not spread viruses. There is no need to monitor it. So it’s normal not to report it.

6. Trojan horse is a kind of virus in the broad sense. It can be killed by anti-virus software. There is no need to install another Trojan horse killer.

7. Do viruses respect national boundaries? No distinction! Foreign anti-virus software can kill Chinese viruses very well. But each country does have its own special network environment, especially China. . . .

Therefore, it is impossible to kill all foreign anti-virus software. However, China’s anti-software technology is not good enough, and many viruses cannot be killed. Therefore, I still recommend using foreign anti-virus software, which can be equipped with some domestic security auxiliary tools or find domestic anti-virus software to assist in killing. (By the way, Kabbah is the best localized foreign anti-virus software and has fully entered the Chinese market. There is a virus center in China, which is no different from domestic anti-virus software, but it also has more anti-virus software...) (Also, it’s interesting. What's more, some foreign anti-virus software are not good at killing Chinese viruses. . Some foreign anti-virus software may falsely report or even kill certain domestic software because localization is not good and those domestic software are not added to the whitelist. But we can't blame them entirely, because some domestic software is very rogue, like Trojan horses or spyware. It eavesdrops on users, steals data, or sends random advertisements. It would be strange if they are not killed.

9. If you dare to run around naked, you will be infected in China’s computer environment within 3 days. Aren't you afraid of a full disk format or Ghost restore? Some viruses can enter the BIOS, CMOS or even more outrageous places, even if you check the disk 10 times, it will be useless! Ghosts can also be destroyed by poison. Be honest and install security software.

10. Firewalls are only used to prevent hacker network attacks, not anti-virus, and they do not scan network traffic for poisons (it does not have a virus database). Anti-virus and monitoring the content of network traffic are the tasks of anti-virus software.

In short, there is no best anti-virus software, only the one that suits you and your machine best. Security awareness and computer knowledge are the most important! When choosing anti-virus software, you must also comprehensively consider detection rate, defense, resource usage, compatibility, stability, speed, etc.

Also, it is best not to choose an anti-kill software that is too famous. There are many free-kills. Kabbah has a low detection rate because it has many free-kills. It is very important to avoid killing. Panda Burning Incense is caused by adding a shell to the Weijin virus (packing is one of the common methods to avoid killing), and many anti-virus software crashes. . . . Of course, the famous anti-virus software also has its strengths. . . Consider it all.

In addition, you can install 2 anti-virus software, but some anti-virus software conflict with each other, so don’t try randomly. It is not recommended to install two, as it may not be much safer, it also takes up resources, and may conflict. You can install a green version of anti-virus software without monitoring, there are people online who can do it. There are also some anti-virus software that have free pure scanners for people to use, such as a-squared’s free version, Big Spider’s dr.web cureit!, and McCafé also have them. Of course, you can also install multiple anti-virus software and turn off the monitoring of some of them

That’s all, choose yourself
