Personal Summary of computer anti-virus knowledge

Common computers may have been infected with viruses. computer viruses are troublesome nowadays. This is not a computer problem, but a virus problem. The damage and attachment capabilities of the current virus are far better than those of the past. Anti-Virus is also a headache. Sometimes the computer is poisoned. We spent a few hours investigating and killing the virus, but we finally found that the exception caused by the virus still exists. That is to say, the virus was not successful, at this time, the confidence of many people has been greatly affected. If this step fails, the average person will first back up and re-install or restore the system, which is full of annoyance, there are also some experts who will kill again in the security mode. Maybe several of these people will succeed, but more people are still doing futile work, the last step is back to restoring or reinstalling the system after the backup. If it fails, people are very angry. At this time, they are very impulsive when restoring or reinstalling the system, most of the time, I regret deleting a file without a backup! Haha ...... If you are troubled once a month, the virus will drive you crazy.

In fact, poisoning is similar to catching a cold. You can avoid catching a cold at ordinary times. Of course, as long as we usually run the system in a safe environment, occasionally checking and upgrading this environment can also greatly reduce the probability of poisoning. Next I would like to talk about some of my suggestions on system security.

The first point is the system selection. Selecting a safe operating system is the first step in anti-virus. This is also a major reason for the popularity of Linux. However, the Linux Desktop function is not as good as that of windows, windows OS is commonly used. XP is another popular operating system after 95 and 2000. Currently, the most popular Operating System is used. Although Windows 7 has released the RC version, but the RTM version does not come out! Because of its compatibility, many software programs cannot perform well on Windows 7, the school's ruijie is a good example.

The second step is to give the computer a safe and stable virus filtering environment, that is, real-time monitoring of viruses, cut off the source of virus spreading to your PC, and avoid viruses thousands of miles away. Our computer is usually poisoned by browsing the webpage with viruses, downloading toxic files, using a toxic USB flash drive or mobile hard drive, and viewing the emails with viruses. Therefore, we should prevent these viruses first. Virus webpage transmission is a major way to spread viruses. Therefore, we must do a good job of anti-virus. Currently, the 360, Super Rabbit online genie, and rising card games we commonly use can be well prevented, here I recommend "Kingsoft Network Security", which occupies very few memory and CPU resources during operation, and features are very specific and free, and Web page monitoring work is well performed, with it, you can reject viruses from outside the browser! We certainly need an anti-virus software to monitor toxic files and USB viruses. The NOD32 in this school is very good, although it is a little slow at startup, however, it can be unambiguous in monitoring, and the resources used are also very small, and the reputation in the world is quite good! Therefore, the two software can provide good protection for virus monitoring. However, it is necessary to install a rising Kaka or 360, because many software comes with plug-ins or something, with these system tools, we can quickly optimize or clean up useless plug-ins, and they also have good real-time monitoring and system optimization capabilities! My computer monitors are provided by "Kingsoft network security (free and updated)", "NOD32 (free and updated on campus)", and "360 (free and updated) "responsible, hence closing the door to the virus!

The third step is to close the "backdoor" for the virus. Some Virus Variant monitoring software is difficult to monitor, or the virus library of the software is poisoned before it is updated, in this case, we need to close the backdoor for the virus so that our information will not be transferred by the virus. Therefore, it is necessary to install a firewall, once the virus has an impulse to connect to the Internet, we can find it and it should disappear! There are many types of firewalls on the Internet, some anti-virus software also comes with a firewall, but in order to close the door, I used a professional "Skynet firewall ", "Skynet firewall" can be easily downloaded to the cracked version on the Internet (we can only use this as a student )!

Fourth, we can also back up and restore the system, clean up junk, install patches, update software, and speed up system operation and stability! My system is XP. during normal operation, the memory usage is a little more than MB, and the CPU usage is rarely too hot. The security and stability of the system are also very satisfactory to me!

Here, if you say, "My computer has been poisoned, but I just don't know how to kill it. What should I do ?" I cannot do it either ...... You can reinstall the system or find a master to clean up the virus in your system. Then, wear the armor I mentioned above and check the software updates and monitoring logs in a timely manner, the probability of virus poisoning is not very high. However, if you don't catch a cold virus at all, no matter what prompts you just click "let go" or "allow", I will also be dizzy, don't say, this is what many of my classmates do. I don't know how to say it, especially some female students! Haha ......

Finally, I want to give a trick to my fellow male who are interested in computers and are enthusiastic about using a USB flash drive, there is a green and upgradeable anti-virus software (Jiangmin 2007) in it. Generally, the USB flash drive system downloaded from the internet has many common tools. if you add a antivirus tool, it is not more interesting, when it's okay, I can help my female to kill the virus ......

The above are my summary. If you have any mistakes, please correct them ...... Happy Dragon Boat Festival!
