How does the computer find out how to deal with ARP virus

ARP virus believes that everyone is somewhat aware of it, although many people do not know what kind of virus it is, but it is not a small hazard to us, mainly on the network. ARP virus is also called ARP address spoofing virus, which is a special type of virus. The virus is generally a Trojan virus. It does not have the characteristics of active transmission and does not self-replicate. However, it will send fake ARP packets to the whole network because of its attack, which seriously interferes with the normal operation of the whole network, and its harm is even worse than some worms. The virus is much more serious.

When the ARP virus attacks, the network usually drops, but the network connection is normal, some computers on the intranet cannot access the Internet, or all computers cannot access the Internet, cannot open the webpage or open the webpage slowly and the LAN connection is broken. The phenomenon of continuous and slow network speed seriously affects the normal operation of LANs such as enterprise networks, Internet cafes, and campus networks.

The following six steps can effectively prevent ARP virus:

1. Bind the IP-MAC address (ie, bind the IP address to the hardware identification address). Bind to the client, this is a good way to make the LAN immune to ARP virus intrusion.

2. All the computers on the whole network are patched with MS06-014 and MS07-017, which can immunize most webpage Trojans and prevent viruses from being infected when browsing the web.

3, disable the system's automatic playback function, to prevent viruses from entering the computer from U disk, mobile hard disk, MP3 and other mobile storage devices. To disable the autoplay feature of Windows systems: Enter gpedit.msc in the run and press Enter, open the Group Policy Editor, click: Computer Configuration -> Administrative Templates -> System -> Turn off AutoPlay -> Enabled -> All Drives -> OK.

4, when the network is normal, save the IP-MAC address comparison table of the whole network, which is very convenient when looking for ARP poisoning computer.

5. Deploy the network traffic detection device and monitor the ARP broadcast packets of the entire network to check whether the MAC address is correct.

6, install anti-virus software, timely upgrade the virus database, regular network-wide anti-virus.

For the virus on the network, we should pay more attention to it. Such a virus may cause no small damage and loss to your computer, but there are some ways to deal with it. As mentioned in the above tutorial, Everyone has nothing to do to prevent it.
