In the virus everywhere today, the network security is more and more attention by the enterprise. The prevention of virus intrusion is a shortcut to improve the security of enterprise network. According to the survey data show that nearly 80% of the network security accidents are caused by the virus, and nearly 50% of these viruses are transmitted by mail for the carrier, which shows the harmfulness of the Mail virus.

Relevant expert analysis pointed out that, when the e-mail gradually became the main communication mode of the daily office of many enterprises, the shadow of the virus began to surround around the e-mail, many enterprises are suffering from the mail virus. Especially for businesses that often need to send and receive mail, they are most worried about mail security issues.

As an enterprise network management, how to comprehensively prevent the mail virus erosion, to the day-to-day office of the enterprise to create a safe application environment? Consider a level of management experience, not only these problems. If the enterprise employees accidentally opened the message with the virus, found it too late, how should the network management? This is the critical moment of the Test level.

I think most of the first time network management must be the use of anti-virus software killing. Of course, there is a virus to kill, the idea is understandable, processing is also the simplest. However, you may overlook several very important steps. In this regard, China Connaught Network security experts to teach you how to safely quickly clear the virus mail.

First: Quickly disconnect the network. When you find yourself in a bad spot, the only thing that happens is to disconnect your network to avoid further spread of the virus.

Second: timely backup files. When you do the first step to disconnect the network, then is to delete the virus with the message, and then run anti-virus software to clean. However, in order to prevent the killing of antivirus software or to delete documents and important messages that you have not yet finished processing, China Connaught Network (www.nuo.cn) security experts recommend that the relevant important documents and data transfer backup to other mobile storage disk, such as USB disk, mobile hard disk, burning disk, etc., try not to use the local hard drive To ensure data security. However, let me remind you not to quit Windows, because once the virus attacks, you may not be able to enter Windows.

If you make a ghost backup in peacetime, use the image file to restore the system, so that even the potential Trojan is cleared, of course, this requires your ghost backup is safe without viruses.

Third, the use of anti-virus software. After you have done your preparation, you should shut down your computer and then start the machine, and then use a clean DOS boot disk to boot the system. In addition, due to poisoning, Windows has been damaged some of the key files, will frequently illegal operation, so Windows anti-virus software may not be able to run, so should prepare a DOS antivirus software just in case.

Even if you can run anti-virus software under Windows, try to use more than two tool software to cross clean. In most cases, Windows may have to be mounted because the virus destroys some of the files and slows the system down or makes frequent illegal operations. Because antivirus software in the development of different focus, the use of anti-virus engine, a variety of anti-virus software has its own strengths and weaknesses, cross-use effect is more ideal. Now the popular anti-virus software in the technology has improved, and can update the virus in a timely manner, so the general situation you encounter the virus should be in the range of antivirus software.

IV: Information security processing. After the anti-virus, in order to be safe, should promptly modify the relevant account information, including login network username, password, mailbox and QQ password, to prevent hackers have been in the process of the last time you know your password. In addition, since many worm outbreaks will send out random messages from you, it is necessary to make appropriate changes.

V: Choose a more secure and reliable mailbox service provider. At present, the market on the enterprise mailbox service providers have a lot, the quality of different mailbox products are uneven, but there is nothing wrong, that is the choice of high credibility of the mail service provider is right. As a global e-commerce expert, China Connaught Net (www.nuo.cn) is one of the few high-quality enterprise mailbox service providers.

In order to protect mailbox security, Connaught "corporate Global Mail" was the first to configure high-end intelligent Kbas Anti-Spam virus mail firewall, using heuristic algorithm, content analysis combined with behavioral analysis technology, every day can filter more than 350,000 messages from around the world, which can accurately identify about 95% of the spam message. At the same time, Connaught "corporate Global Mail" using the world's top automatic virus protection strategy, dedicated mail anti-virus engine, real-time capture of the latest virus, 24-hour uninterrupted monitoring of the global virus epidemic, spam interception rate to achieve relatively satisfactory results.

It is understood that Connaught "corporate global Mail" has repeatedly received "service star" "Trust brand" many awards.

Sixth: Prevention of mail viruses. As the saying goes, "take care of the boat", sailing so, use enterprise mailbox operation should also be so. In fact, the spread of the general mail virus is carried out through the attachment. And the Mail is "dead", usually entrainment in the mail virus is not active to live, if you do not go to the point of running it, it will not infect your system.

In this, China Connaught Network security experts remind, do not easily open the letter of strangers in the attachment file. When you receive an interesting email from a stranger who claims to be a must-see, do not open it without thinking. Especially for some executable files such as ". exe", be cautious.

For the more familiar friend sent the letter, if the attachment in his mail, but he did not mention in the mail or description, also do not run easily. Because some viruses are secretly attached to it may be his computer has been poisoned, but he did not know. such as "Happy99" is such a virus.

When sending a program file to someone or even an electronic greeting card, make sure you have no problems before sending it to avoid becoming a transmitter of the virus. In addition, should avoid blindly forwarding. Some friends, when they receive messages that they think are interesting, not too late to look at the open Address Book to each of their friends forward a copy, which is very likely to make the virus, the creator of the bad deeds, and your friend to your letter is no doubt that there will be no doubt, as a result, you inadvertently become the spread of the virus.

Some are hidden in a Word file in a macro virus, so be careful about attachments in the form of Word files. Another virus is transmitted using ActiveX. Because some email software such as Outlook can send HTML-formatted messages, and HTML files can contain ActiveX controls, and ActiveX can in some cases have access to your hard disk, HTML-formatted messages with viruses, Can be activated when you browse the contents of a message, but only in HTML-formatted messages.
