This document applies to LDMS 9.5 and 9.6

OS affected: Windows 8.1 x86 only

Issue

Kaspersky has notified us of a bluescreen issue seen on Windows 8.1 x86 with LDAV (Kaspersky) installed after applying KB3013769.

Kaspersky is working on this issue with Microsoft.  As we receive more information, details will be added.

Current Status

Workaround available:

Kaspersky has released a content update that changes their AV definitions for Windows 8.1 x86.  This update partly disables internal functionality.  It is possible that there will be a small decrease in detection rates.  On Monday December 15th, they expect to release updated definitions that restore full functionality.

After updating AV definitions KB3013769 can be applied.

Because the fix is in the definitions, BSOD can still occur when installing LDAV on Win 8.1 x86 systems if KB3013769 is installed.  In this scenario, uninstall KB3013769, install LDAV, update definitions, and then reapply KB3013769.

If you are currently experiencing a bluescreen issue on Windows 8.1 with LDAV installed, please contact our support center so we may provide any forthcoming fixes.
