Network Management Tips: The intranet upgrade speed is greatly improved

For small and medium-sized enterprise network administrators, it is often necessary to ensure the smooth operation of the enterprise intranet, and the smooth operation of the Intranet is closely related to the security of employees' computers. I believe most enterprises have installed anti-virus software for employees' computers, however, even with anti-virus software, it is impossible for us to completely prevent viruses and hackers from attacking the enterprise's Intranet, because whether the virus database is updated on time plays a decisive role. However, during actual use and maintenance, many network administrators will find that the update speed of anti-virus software is very slow, which affects Enterprise Intranet security to a certain extent, today, I am going to show you how to skillfully set up the upgrade speed of the Intranet anti-virus software based on my own experience. I will take the most widely used Kav as an example.

I. Kaspersky's automatic upgrade speed is not ideal by default

The anti-virus software used by my company is Kaspersky. The anti-virus software is automatically upgraded at ordinary times. However, there are always employees who report that the upgrade speed is very slow, I also specifically checked that the problem with the upgrade speed of Kaspersky Anti-Virus Software on the computer exists. During the upgrade, the transmission speed is less than 1 kb per second. It takes several hours to update the software smoothly.

Ii. analyze the root causes of symptoms

Next I analyzed this problem, found that the problem of employee computer upgrade interface position is displayed as aspersky.com "> http://dnl-06.geo.kaspersky.com, and the display position is http://dnl-us.kaspersky.com. That is to say, the reason for the slow speed is that Kaspersky connected to the upgrading server of these addresses during upgrade, after comparing the employee's computer, it is found that all the upgrading servers that can be quickly upgraded Kaspersky accesses during the upgrade are similar to the http://dnl-cn.kaspersky.com address, which is obviously the upgrading server in China.

It seems that the slow upgrading speed and problematic employee computers are mainly caused by problems with the selected server address.

3. cleverly set and solve the problem of slow upgrade

Now that we know the problem, we will start from upgrading the server to solve the problem. In Kaspersky Anti-Virus Software, We can manually set the address for upgrading the server. The specific operation is to open the Kaspersky main interface, choose "Settings"> "service"> "Update"> "Custom" in the upper-right corner, and then select "add" in the upgrade server, then add an address similar to the http://dnl-cn.kaspersky.com in the upgrade server address so that you can effectively ensure that the virus library is automatically connected to the upgrade server faster.

4. Advanced Settings completely solve the problem of slow upgrade

However, there is also a problem with the previous method, that is, this method of manually adding addresses only applies to a server. If the network condition is poor or the server stops providing Update Services, our Kaspersky will never be able to use the updated component function. However, I have found a good solution, that is, to allow Kaspersky to find the best balance between automatic server selection and balanced speed by setting the country and region. The specific method is as follows.

Step 1: Open the main interface of Kaspersky and select "Settings" in the upper right corner ".

Step 2: Find "Update" under "service" on the left of the settings window, click "Custom" on the right, and select the "Update Server" tab.

Step 3: There is a drop-down menu under this label, which provides the area we selected. Of course, the previous employee computers were not updated slowly because they were not selected here, in this way, the Kaspersky Antivirus software will automatically scan all the update servers and select a relatively fast upgrade. the faulty computer may have problems connecting to the domestic server for some reason during the upgrade, the foreign server is selected, resulting in a slow upgrade speed. In the region drop-down list, we can forcibly specify the country and region where the current computer is located. This ensures that Kaspersky only connects to the upgrade server in China during the upgrade, to a certain extent, the upgrade speed is improved. Select "China" from the drop-down menu, and then check the check box before "confirm the best update region.

Tips

Another possibility is that the upgrade will become a foreign server, that is, the non-Chinese version of the kazki-kill software we use, but the English version. This will also lead to the first consideration of foreign servers during the upgrade.

Step 4: After cleverly setting and updating the region parameter, we have effectively solved the problem of the upgrade speed of Kaspersky Anti-Virus Software. We can clearly feel the difference in the speed when upgrading again, the transmission rate can reach more than 40 K per second.

V. Summary

The fault in this article is mainly caused by the automation function of Kaspersky Antivirus software. It is precisely because of this automatic configuration that the Kaspersky Antivirus software blindly accesses the foreign upgrade server to update the virus database, resulting in a slow upgrade speed failure, this problem is effectively solved when you access the Update Server in China in the selected region.
