hi~everyone,i got some problems with avast.
My system is windows7 sp1 x64,when the avast update completed, i restarted my computer and the bad thing happened 
It was unable to enter the windows beacause of the damn bluescreen !!! so i deleted the aswsp.sys , it’s ok now.but it will lose the self-defense function.
