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
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.
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.

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.
