I’ve encountered an issue where Winpkfilter & Kaspersky Internet Security being installed together will totally lock up a Windows Vista Home Premium installation.
This lock up can be reproduced using the following steps:
Install Vista Home Premium Service Pack 1
Turn on windows Firewall and Defender
Run windows update and install all updates
Install Kaspersky Internet Security 220.127.116.11 d.f
Activate the install with the licence Code (Note: this is important – and unactivated version of Kaspersky doesn’t cause the lock up)
Update Kaspersky to latest definitions
Install Winpkfilter 3.0.4 run-time libraries (Note: at this point the installation seems to work fine and I tested a couple of the sample apps which appeared to work fine)
Shortly after the machine has rebooted it will lock up totally. It will even lock up if you try to boot in safe mode. This will continue happening until you boot from the CD and restore the machine to before installing winpkfilter.
We have tested the suggested configuration with Kaspersky Internet Security 18.104.22.1685 (the latest one available from the official web site) and have not figured out any problems. May be the problem was specific to 22.214.171.124 and fixed in the current version.
Could you try to reproduce it after updating KIS to 126.96.36.1995?
We have received few complains on WinpkFilter conflict with KIS 2008/2009, however we were not able to reproduce (it looks it happens only on small amount of systems) and thus can’t understand and fix this problem so far.
It looks that the “lock up” you have expirienced depends from hardware configuration (installed hardware drivers) or some third software component in addition to KIS and WinpkFilter. Could you please post or e-mail to support(at)ntkernel.com the details of the software/hardware configuration?
