How do users choose anti-virus software after mistaken removal (five misunderstandings)

In the anti-virus software industry in China, after being "mistaken" by Norton and Kaspersky and the "verbal War" by antivirus software vendors at home and abroad, how to judge and choose anti-virus software makes users feel at a loss.

In view of Chinese users' questions about anti-virus software, after a series of practical comparison tests, we can find several misunderstandings about the selection of anti-virus software for users below, hoping to help readers.

Misunderstanding 1 whether it is genuine or pirated, no matter the charges are free, you can use any installation

At present, a considerable number of users download some so-called "cracked version" anti-virus software through forums and websites. After installing the software, they can still scan for viruses and upgrade the virus library. Many users download some free or trial anti-virus software from the website.

I would like to remind you that, unlike other software, the money spent on anti-virus software is not enough to minimize the risk of computer and data security.

Although the use of pirated anti-virus software is no different from that of genuine ones, in fact, most pirated anti-virus software damage some data during the cracking process, resulting in unavailability of some key functions, or the system is unstable.

Some of the better-intentioned hackers directly bind viruses, Trojans, or backdoor programs to the anti-virus software they have cracked. The anti-virus software itself has security risks. What about security protection?

Talking about free software, although there are a lot of free anti-virus software on the Internet, such as the famous McAfee, will also provide a free trial for a year, but there is no free lunch in the world. Most of these free anti-virus software is used for trial purposes to attract customers to purchase, making it difficult to provide continuous free services. Some of the detection and removal functions also delete free users. In addition, some manufacturers may bind rogue software to free software.

Buy genuine anti-virus software and buy security and services. Genuine anti-virus software can provide continuous upgrades, after-sales services and a variety of safeguards. using pirated or free anti-virus software seems to be cheap, but when the problem really happens, you will find that the actual gain is not worth the candle.

Misunderstanding 2 reinstall the system when there is a virus, so you don't have to spend money on anti-virus software.

Many computer players think that their computers have good knowledge and no important data. Even if they are infected with viruses, they can directly format and reinstall the system. Anti-Virus Software is never used. In the past, virus writers used programming techniques, which often caused a virus to have obvious attack characteristics. Nowadays, virus writers aim to obtain economic benefits, and the virus will run quietly in the background, hackers steal game players' account information, QQ passwords, and even bank card accounts, but do not show obvious Attack Characteristics on the surface. When a virus is detected, the user's account information is stolen.

Misunderstanding 3 it is best to use anti-virus software to scan and kill all viruses, with fast anti-virus and low memory usage.

This is the naive idea of computer users who are pursuing "perfectionist. It is impossible to require antivirus software to scan and kill all viruses. Anti-Virus Software Vendors must first intercept the virus, analyze and test the virus characteristics, and then upgrade the anti-virus software virus database so that the user's anti-virus software can be immune to the virus. Second, the speed of virus detection and removal is not an important criterion for judging the advantages and disadvantages. A good anti-virus software engine requires analysis, shelling, and even virtual execution of files, which takes some time. Some anti-virus software engines are relatively simple. They do not analyze files much and only perform Feature Matching. The virus detection speed may be very fast, but the virus may be missed. In addition, it is one-sided to simply check the memory usage of anti-virus software, without looking at the actual functions of anti-virus software, and then judge the resource usage of a software.

An excellent anti-virus software includes a registry, vulnerability attack, mail sending, receiving, webpage, boot area, memory, and other monitoring systems. With some file-only anti-virus software, the memory usage will certainly increase, but it provides more comprehensive security protection.

Misunderstanding 4: To ensure security, install more anti-virus software

Computer users with "security first" believe that in an environment with severe Network viruses, they must install more anti-virus software to ensure security, many users have installed Multiple antivirus software and virus firewalls on their computers. We would like to remind these users that anti-virus software works in the same way. After similar software is installed and enabled at the same time, various anti-effects may occur.

For example, conflicts between anti-virus software and scanning by competing for a file during real-time monitoring results in slow or unstable system operation. Excellent anti-virus software provides comprehensive monitoring, defense, and detection capabilities, so you do not have to install them repeatedly.

Misunderstanding 5 good anti-virus software abroad (or strong local anti-virus software)

The foreign anti-virus software technology is more powerful, and it is more secure to cope with global viruses. Many foreign manufacturers are paying more and more attention to the Chinese market.

Anti-Virus Software in China has local advantages. In addition to internationally popular viruses, it also gives priority to the development and removal of localized viruses, based on its local advantages, it gives Chinese users a higher priority and guarantee in upgrading and after-sales services.

Anti-Virus Software in China has a certain price advantage, and the technical level is also increasing. Users should not wear colored glasses to look at a product.
