Choosing the right anti-virus software for your own

Anti-virus software has received much attention because it is responsible for the security of the user's system. Without the protection of anti-virus software, it is vulnerable to virus attacks, resulting in the loss of valuable data and causing unnecessary losses to itself. In the dazzling array of anti-virus software brands, how to choose an anti-virus software suitable for your needs is a problem that every user wants to solve. The most important thing to choose an anti-virus software is to buy on demand, so that you can reduce the impact of anti-virus software on your computer's performance from a practical point of view while meeting your own needs.

1. Anti-virus ability

The quality of anti-virus software does not depend on the manufacturer's advertising, but needs to be certified by authoritative and scientific methods. What the hearsay can't be used as a criterion for judging the quality of an anti-virus software. When purchasing an anti-virus software, the first thing to look at is whether there is a computer security product sales license from the Ministry of Public Security. If the product passes the certification of an internationally recognized certification body, it means that its anti-virus capability is credible. . Of course, before buying, you can find out how the anti-virus software is in the user's reputation, how to upgrade the service, which plays a reference role before buying. However, it should be noted that many times the information that is inquired cannot really represent the actual performance of the software. If there are conditions, you can try it before purchasing to see if it can meet your own needs.

2. Stability

As a special kind of software, anti-virus software needs to be closely connected to the system. Reliability, stability, and compatibility are especially important. Don't pay attention to the amount of antivirus and ignore reliability, stability, and compatibility. Anti-virus software is generally started with Windows. If the stability of anti-virus software is not good, it is very likely to cause system instability. Similarly, if an anti-virus software does not have good compatibility, it will be compatible with other software on the computer. The phenomenon of crashes and frequent crashes occur frequently. How can this anti-virus software meet your needs?

3. Can support multi-user environment

With the widespread use of Windows 2000 and Windows XP, a computer can be used by multiple people at the same time without mutual influence, and the multi-user system has gradually entered people's daily use. Come in. Anti-virus software that supports multi-user environments enables real-time monitoring systems to work regardless of whether the operator has administrator privileges or non-administrator privileges. Anti-virus software that does not support multi-user environments, often has the problem of not being able to use anti-virus software monitoring systems in non-administrator users. The consequence of this is that non-administrator users cannot get protection from the real-time monitoring system, causing the computer to be infected by viruses and causing unnecessary losses. Therefore, it is necessary to choose an anti-virus software that can work in a multi-user environment.

4. Perfect real-time monitoring system

The channel of computer virus intrusion is nothing more than removable storage (such as floppy disk, CD-ROM, flash memory, etc.), network, and e-mail. The condition that the virus infects the computer is to enter the memory. run. If you have a complete real-time monitoring system, you can block it before you infect your computer to avoid infection. Nowadays, various emerging network switching methods are emerging one after another. The use of instant chat tools is more and more extensive, and the functions are becoming more and more powerful. Various Office macro viruses are also frequently appearing. In this case, anti-virus software with embedded anti-virus can check these emerging exchanges as quickly as possible to determine whether there is a virus. Therefore, using anti-virus software with real-time monitoring, you can build a dynamic, real-time anti-virus defense line for computing organizations, and reject viruses outside the computer system. However, the real-time monitoring system has a certain impact on the system performance. Selecting a real-time monitoring system with a small amount of anti-virus software will reduce the inconvenience to the user.

5. The ability to detect compressed files

The strength of anti-virus software for compressed file detection and the number of compressed file formats supported can be an important basis for our purchase. The various resources on the network are basically compressed. These compressed files may carry viruses and may pose a serious threat to our computer systems. In addition to the common ZIP format, RAR format, we can also encounter formats such as CAB, so anti-virus software is necessary for anti-virus detection capabilities of a variety of compressed file formats. At the same time, the detection method that can directly remove the virus in the compressed package without removing the virus after the user manually decompresses is also being adopted by more antivirus software vendors.

6. The speed of killing and killing

The capacity of the hard disk is getting bigger and bigger, and the data stored in the hard disk is also a lot. If there is no efficient efficiency of checking the virus, then for the data of dozens of GB, it is necessary to check all the data. The time required can be imagined. Moreover, there are already tens of thousands of known viruses, and most of them have been unable to infect files due to continuous computer replacement and improved operating systems, and have lost the ability to infect viruses. Under normal circumstances, we have encountered some popular viruses. If you can check your system against these more popular viruses, the scan time saved is quite a lot.

7. Emergency Recovery Function

Emergency Recovery is a must-have feature for excellent anti-virus software. In addition to being able to boot the computer, the emergency boot disk must be able to properly back up and restore the master boot record and boot sector to recover from a system crash due to virus intrusion. At the same time, the emergency boot disk with the NTFS file system killing function will also bring a lot of convenience to users who use the NTFS file system.

8. Network Firewall

Network Firewall is different from virus firewall and is mainly used for various attacks on the network. Using a network firewall allows your computer to be disconnected from the network and protected from hackers. Especially for users who use broadband networks, purchasing anti-virus software with a network firewall will enhance the protection of the system.

9. After-sales service

The after-sales service of anti-virus software is different from the general software. Due to the rapid development of viruses, new viruses are generated every day. Therefore, anti-virus software manufacturers are required to provide timely, fast and simple upgrade services. In addition to regular Internet updates, it is important to provide additional updates.

The speed of anti-virus software update is also a key point to consider when purchasing. The ability to update anti-virus software in a timely manner will determine our ability to withstand new viruses, especially when a major outbreak is discovered, and we need to be able to provide upgrades at the fastest speed. At present, most anti-virus software can be updated at least once a week, and some even update every day.

Finally, because anti-virus software is used by users with different proficiency in different computer environments, this requires anti-virus software vendors to provide different services for different users, such as answering users to install, uninstall, and use anti-virus software. Problems encountered in the process and handling of abnormalities in the user's computer. In addition to the general telephone support, the timely answer and online technical communication of Email must also be the target of the assessment.

10. Small functions included

As a computer security software, anti-virus software, like other computer security software, is a function to protect the security of users' computer devices. If it can provide some other small security for computer security. Software (such as killing, vulnerability detection, registry recovery modified by malicious code, etc.) will bring a lot of convenience to users. You should be aware of these small details when purchasing. From these small details, you can see how an anti-virus software vendor treats users.

It is not that an anti-virus software can fully meet all the above requirements. Installing two or more anti-virus software is a common phenomenon in daily use. However, it should be noted that if you run two or more anti-virus software at the same time, it is likely to cause problems in the system. Therefore, a better method is to open only one real-time monitoring of anti-virus software, and another anti-virus software is used for manual killing in general. This can not only meet the daily real-time monitoring needs, but also use two or more anti-virus software to check the system, which has the effect of cross-virus.
