	Can Kaspersky Anti-Virus 6.0 for Windows Workstations use previous version of interception-driver?

Kaspersky Anti-Virus NDIS Filter is an interception-driver of network packets. Interception mechanism is implemented by the technology NDIS Intermediate Driver . This method of embedding into the system is recommended by the Microsoft Company as it provides maximum compatibility both with different OS’s versions and with other applications and drivers.

The established network connections might be broken during the application installation because of the new driver.
