With the development of the network, the dissemination of information more and more quickly, but also to the spread of the virus to facilitate, the popularity of the internet makes the virus in the overnight spread around the world possible. Now, almost every computer user has been infected with the virus experience. Experienced virus intrusion, file loss, system damage users, will be aware of the harm of viruses, but also have the awareness of the virus prevention, but how exactly how to prevent the virus? I find that there is a misunderstanding in this respect.

First of all, anti-virus software is not omnipotent. Many people think that as long as the anti-virus software installed, you can rest easy, in fact, this is wrong. Now the virus common use of system vulnerabilities to attack, through a wide range of network address scanning, will spread itself. So, how to effectively protect the system from virus infection? The key is to patch the system in time. The system's patch will block the virus using the backdoor, the virus will be rejected outside the system, an effective protection system. Set the computer password.

With a system patch and a secure password, such a system is basically secure, but not 100% secure. Antivirus software is still to be installed, it can help you prevent those emails and web pages of viruses, as well as you download from the Internet or with friends of the files of the virus. At the same time, antivirus software can also early detection of viruses, protect your files from virus infection.

To effectively protect against viruses, you need to do the following:

1, timely patch to the system, set a secure password.

2, install anti-virus software. If you don't have virus protection software installed on your machine, you'd better install one. If you are a home or personal user, downloading any one of the best ranked programs is fairly easy, and you can follow the Setup wizard. If you are in a network, first consult your network administrator.

3, regularly scan your system if you happen to be the first time you start antivirus software, it's best to let it scan your entire system. It's a good thing to start your computer with clean and virus-free problems. In general, antivirus threads can be set to scan the system every time the computer starts up or run on a regular schedule basis. Some programs can also scan the system in the background when you connect to the Internet. Regularly scan the system for infection with viruses, preferably become your habit.

4, update your antivirus software now that you have the virus protection software installed, you should make sure it is up to date. Some antivirus programs come with an automatic connection to the Internet, and as long as the software vendor discovers a new threat, it adds functionality to the new virus detection code. You can also find the latest security update files in this scan system.

5, do not click on the link and download software, especially those sites contain obvious errors of the page. If you need to download the software, please go to the formal official website.

6, do not visit anonymous and unfamiliar websites, to prevent malicious code attacks or malicious tampering with the registry and IE homepage.

7, do not strangers and unfamiliar users chat, especially those QQ virus carriers, because they automatically send messages, which is also the obvious characteristics of their poisoning.

8, close useless applications, because those programs will often constitute a threat to the system, but also occupy memory, reduce the speed of the system.

9, install the software, remember not to install its carry software, especially rogue software, once installed, want to delete all deleted, generally need to reinstall the system to clear.

10, do not easily implement the attachment in the EXE and COM and other executable programs these attachments are very likely to carry a computer virus or hacker programs, easy to run, it is likely to bring unpredictable results. Attachments to the electronic mail that can be sent to a known friend or stranger must be checked and determined to be used.

11, do not easily open the attachment of the document file sent to the other side of the e-mail and related accessories of the document, the first to save as a command (save As) saved to the local hard disk, to be used to check the computer virus software is non-toxic before you can open the use. If you use the mouse directly click on the two doc, XLS and other attachment documents, will automatically enable word or Excel, if there is a computer virus in the attachment will immediately infect; if there is a hint of whether to enable macros, it is absolutely not easy to open, otherwise very likely to infect the e-mail computer virus.

12, do not run the attachment directly to the file name extension is very strange attachment, or with a script file such as *. VBS, *. SHS and other accessories, do not directly open, you can generally delete the e-mail containing these attachments to ensure that the computer system is not affected by computer viruses.

13, mail settings if you use Outlook as the e-mail software, you should make some necessary settings. Select the Options command in the Tools menu, set the security for the attachment to be high in security, and press the Add-on Manager button in the other to press the Add-in option button without selecting the server script to run. Finally press the OK button to save the settings.

14. Use the preview function with caution if you are using Outlook Express as the e-mail software, you should also make some necessary settings. Select the Options command in the Tools menu to automatically display the news message in the Preview pane and automatically display the picture attachment in the news message. This prevents some e-mail viruses from using the default settings of Outlook Express to run automatically, destroying the system.

15. Uninstall scripting host for computers using the Windows 98 operating system, in the Add/Remove Programs in Control Panel, select Check to see if Windows Scripting Host is installed. If it is already installed, uninstall it, and check the Windows installation directory for Wscript.exe files and delete them if they exist. Because some e-mail viruses use Windows Scripting Host for destruction.

16, alert to send out of the mail for their own outward transmission of the attachment, also must be carefully checked to determine non-toxic, before you can send. Although the electronic computer virus is quite scary, as long as the protection is proper, or can avoid the infection of computer viruses, can still be assured to use. Through the above description of the worm virus and the symptoms of outbreaks, I believe that we have a deeper understanding of it. Because the worm is spread through the network, in today's highly developed network period, worm is impossible, we only build their own computer on the firewall and develop good surfing habits, to minimize the harm.

It is believed that when your computer has done the above protective measures, the virus will not harass you again.
