BitDefender ranks first

Introduction: BitDefender antivirus software is an old-fashioned antivirus software from Romania, with a huge virus database of 240,000. It will provide maximum protection for your computer, with powerful anti-virus engine and internet filtering technology, and provide you with instant information protection function. Answer a few simple questions, you can easily install and support online upgrade. Include 1. Permanent antivirus protection; 2. Background scanning and network firewall; 3. Safety control; 4. Automatic rapid upgrade module; 5. Create a scheduled task; 6. Virus quarantine area.

Personal evaluation: BitDefender Pro version v9.0

The number one software turned out to be something I had never used before. Domestic forums and software sites have not given it a high evaluation. Since it is the first one, I will try anyway. It's very thoughtful to remove mcafee and install BD. BD mainly has three functions-anti-virus, anti-LJ and firewall (these three options are optional, I never install a firewall, so one IP strategy goes all over the world). Because it is still in trial, it is impossible to give a deeper evaluation.

Main features: 1. Setting options are easy to understand and use; 2. The virus database is frequently upgraded, and if the virus is popular again, it will be killed, killed and killed; 3. There is a registration machine that can be upgraded online (Khan! Does that count? Of course, poor people like us should also be "free".

Disadvantages: 1 There is no Chinese version. Although there is a Chinese version, I always feel that it is not as good as the Chinese version. 2. There are too many startup add-ins. A * * * has seven main processes, accounting for about 20M, and the others are 3-4M.

BitDefender antivirus version 10

ESET Nod32 ranked fifth.

Introduction: The authoritative evaluation of foreign anti-virus software gave NOD32 a high score, and won more than 40 awards around the world, including virus bulletin, PC magazine, ICSA, Checkmark certification, etc. It is the only anti-virus software in the world that has passed VB 100% test for 26 times, ranking first among all products! The product line is very long, from DOS, Windows 9x/Me, Windows NT/XP/2000 to Novell Netware Server, Linux, BSD and so on. It can monitor emails in real time, occupies less memory resources, and the speed and effect of virus removal are satisfactory.

Personal evaluation: NOD32 antivirus v2.5 1.22 Chinese version.

Microsoft's antivirus software, which has been used for four years, is naturally not bad, starts faster, takes up less resources and won many authoritative awards. I just tried it. As my classmates said, it takes up much less resources than the antivirus software I used before. After using it, I think the only drawback is that the upgrade is very slow and difficult. Basically, all the servers that can be upgraded are cracked servers in domestic universities, while the official servers are very slow to upgrade.

Main features: 1. Less resources; 2. Strong anti-virus ability; 3. You can detect whether you are infected with viruses (including files in rar and zip) during file downloading; 4. The scanning speed is super fast.

Disadvantages: 1 The virus database is updated too slowly, sometimes once every few days; 2. It seems that in order to fight against piracy, many anti-virus software kill the registration machine as a virus. Anyone who has used NOD knows that NOD will kill it without asking you what to do, and then give you a hint (are you taking credit or angry with me? ! ), so that several of my registrars were killed, and the next pirated software was opened with NOD. After decompression, only the installer is downloaded-the registrar is XX.

McAfee Virusscan ranks sixth.

Introduction: One of the best-selling anti-virus software in the world, McAfee anti-virus software, not only updated the operation interface, but also combined the company's WebScanX function and added many new functions! In addition to helping you detect and delete viruses, it also has a VShield automatic monitoring system, which will reside in the system tray. When you open a file from a disk, network or email folder, it automatically detects the security of the file. If the file contains a virus, it will immediately warn you and handle it appropriately. It also supports the right mouse button shortcut menu function, which can lock personal settings with a password so that others can't change your settings.

Personal evaluation: Mcafee 10.0.27 Chinese version

In fact, McAfee is not so powerful in killing viruses, and certainly not as savage as Kaspersky, but why does it also have a broad user base and a good reputation? Obviously, the monitoring of macfee is perfect, which can be said to be watertight. I think what are the disadvantages of monitoring such a good anti-virus ability?

Main features: 1. Strong anti-virus ability; 2. It's free. Just register an international email address, and you can enjoy the online upgrade service of this excellent antivirus software.

Disadvantages: 1 Configuration trouble, not recommended for beginners; 2. The virus database upgrade is slow, and it takes several days to upgrade; 3. The program is slow, and it takes several seconds to open the settings.

Norton ranks seventh in antivirus.

Introduction: Norton antivirus software is a powerful anti-virus software, which can help you detect thousands of known and unknown viruses. Whenever you turn on the computer, the automatic protection will remain in the system tray. When you open a file from a disk, network or email folder, it automatically detects the security of the file. If the file contains a virus, it will immediately issue a warning and handle it appropriately. In addition, it also comes with the "LiveUpdate" function, which can help you automatically connect to Symantec's FTP server to download the latest virus pattern, and then automatically complete the action of installing the update after downloading.

Personal evaluation: Norton antivirus 9.0 Chinese version

Everyone is familiar with Norton. To be honest, Norton's advertising campaign is really good, but please be careful, don't look at the advertisement, look at the effect! This is also a year to crack and upgrade the soft virus software that was popular a few years ago. Very powerful. Of course, Norton Enterprise Edition is more powerful than Personal Edition in antivirus. I suggest you use version 9.0. The latest version 10.0 takes up a little more resources and is not perfect. But if you use Norton's complete product, systemworks+ Security Police, you will find that it is slower than snail and slower to start (slower than Kaspersky). I really don't understand. What's the point of using an anti-virus software with CPU P4 1.8G and memory over 700m? So again, if you are willing to sacrifice performance for safety, you can use Kaspersky! Kaspersky is much better than Norton, because it also sacrifices performance!

Main features: Norton antivirus software enterprise edition and professional edition, standard edition can bring you lower system resource occupation and more reliable performance!

Disadvantages: 1 The rate of manslaughter and false alarm is high; 2. After the firewall finds the virus, the prompt message cannot be closed; 3. Slow upgrade.

Personal evaluation: eTrust EZ Antivirus 2005 v7.0 official simplified Chinese version

This compact and powerful anti-virus software produced by CA company is deeply loved by Chinese people through the free download activity jointly organized with Microsoft. Compared with the official Chinese version of Norton antivirus, Kaspersky and other big-name antivirus software, the only regret it has caused to Chinese people is probably the blunt English interface.
