What is Kaspersky Anti-Virus NDIS Filter

Kaspersky Anti-Virus NDIS Filter is a network package interceptor.

The network package interception mechanism is based on the NDIS Intermediate Driver technology.

This embedding method is recommended by Microsoft, and is the only one ensuring maximum compatibility with different operating systems, and all kind of software and drivers.

Information Installing this NDIS Filter driver may interrupt established network connections. This occurs due to its embedding into protocol stack (network adapter <-> TCP/IP) by standard Windows means causing stack drivers to reinitialize and this leads to a connection loss.

After installing the application, Kaspersky Anti-Virus NDIS Filter driver appears in network connection properties:

If there are two or more network connections in the system, Kaspersky Anti-Virus NDIS Filter gets embedded into each one of them.

There is no way to reconfigure the driver.

Kaspersky Anti-Virus NDIS Filter gets installed on the following operating systems:

Condition 1. One of the following operating systems should be installed on the host:

  • Microsoft Windows 2000 Professional
  • Microsoft Windows XP Professional x32 and x64
  • Microsoft Windows Vista Business/Enterprise/Ultimate x32 and x64
  • Microsoft Windows 7 Professional/Enterprise/Ultimate x32 and x64 
Kaspersky Anti-Virus for Windows Workstations, version 6.0.4.x system requirements

Condition 2. At least one of the following application protection components get installed:

  • Mail Anti-Virus
  • Web Anti-Virus
  • Anti-Spy
  • Anti-Hacker
  • Anti-Spam
Information Kaspersky Anti-Virus NDIS Filter is not installed when installing Kaspersky Anti-Virus 6.0 for Windows Servers.

How the system reacts to uninstalling Kaspersky Anti-Virus NDIS Filter

It is possible to delete (uninstall) Kaspersky Anti-Virus NDIS Filter from the system, but this may have undesired consequence if done improperly.

To delete the driver properly, select Kaspersky Anti-Virus NDIS Filter in Local Area Connection properties and click the Uninstall button.

In the aftermath:
  • On Microsoft Windows XP Professional x32 and Microsoft Windows 2000 Professional operating systems, the network package interception would be carried out by the Kaspersky Anti-Virus 5.0 interceptor. The latter comes on the stage only after deinstalling Kaspersky Anti-Virus NDIS Filter.

  • On Microsoft Windows XP Professional x64, Microsoft Windows Vista (x32 and x64) and Microsoft Windows 7 (x32 and x64), the Anti-Hacker / Firewall modules would stop filtering packages and detect network attacks (no network package interception). All the other components would retain the functionality.

Warning It is not recommended to use Kaspersky Anti-Virus NDIS Filter by disabling the option in Local Area Connection. That would make NDIS Filter to switch into a specific mode which could destabilize the entire operating system (e.g. cause a BSOD).

Whenever there are two or more network connections in the system, Kaspersky Anti-Virus NDIS Filter uninstallation from one of them does not affect its performance in the other connections.

Kaspersky Anti-Virus NDIS Filter can be reinstalled after uninstalling.
