SFC finding bluetooth driver.inf - the reason will shock you.

if you run cmd in windows, there is a command called , SFC /scannow , the command scans the computer

and finds if there are any corrupt drivers, and replaces them.

if you use the sfc /scannow command, sometimes you will find a driver that is btxxxxxx.inf , where the x symbols, are numbers.

that is the bluetooth driver itself.

how it happens.

some bluetooth devices have a problem where, if you turn them on, they make a hi pitched signal. a tiny iiiiiiii sound, that is

at around 4 or 6khz, the sound lasts around 2 to 3 seconds, and is very low in volume. sometimes you hear it also in chargers, or other devices,

that are infected, from some kind of bios corruption, and the moment they turn on, they make that hi pitched signal.

if, sfc /scannow finds the btxxxx.inf driver, it replaces it. if you run sfc again, after a clean boot etc, it will not find it.

if you turn on the bluetooth speaker or radio, that makes the signal, the signal will corrupt the bluetooth driver of the windows computer,

even with the computer being switched off. after you turn on the computer and run sfc, the bluetooth driver will appear again.

each time the bluetooth device is turned on, that makes the hi pitched signal.

there are users on the internet as well, who have that problem. where sfc finds the bluetooth driver.

it is the bluetooth devices that make the hi pitched signal apparently.

if you know anything about this problem, dont hesitate to report to your local police, government, or security agency.
