Avast issued an emergency fix for its anti-virus software that fixes a bug that wreaked havoc on some Windows 10 Anniversary Update systems by blasting users with Blue Screens of Death (BSOD). The problem was caused by an unforeseen driver conflict related to the aswvmm.sys driver on systems with an Intel Skylake processor with Intel VT enabled in the BIOS.
Avast quality assurance director Petr Chytil says a driver configuration caused the unforeseen crash.

"While the majority of our users didn’t have a problem, certain HW configurations didn't mix well with the update," Chytil says.

"To be specific, when the Windows 10 Anniversary Update was combined with our aswvmm.sys driver on an Intel CPU from the Skylake family with Intel VT enabled in the BIOS, the update resulted in a blue screen of death.

"This occurred during upgrades to the Windows 10 Anniversary edition from previous versions of Windows, and during clean installations of Avast Antivirus on systems already running the Anniversary Update."
