driver pervac.sys

Hola
mi pc se reinicia y sale una pantalla azul donde indica
PAGE_FAULT_IN_NONPAGED_AREA y hace una mención a PERVAC.SYS
les agradeceria que me digan como solucionar este inconveniente.
He hecho un analisis con el windbg.exe del Debugging Tools for Windows y me
dice
ahi les mando los resultados del analisis del archivo Mini121305-03.dmp que
se crea luego de que se reinicia mi pc.
Gracias y que tenga buen dia.
