Windows 10 computer is frozen because it is loaded when you start the process watchdog avg (before Windows starts). As you explain in your web if I change the name of avg * .sys to avg * .old files in the Windows / System32 / Drivers folder using the bootable flash drive fails because it can not find the avgboota.sys file and I can not boot Windows in safe mode .
