I am actually asking this on behalf of my brother who believes his computer is safe but I have doubtsand so does his lawyer. Unfortunately I do not know the answer to your question without asking him and he dosnt think he needs professional advice.
Can you answer my question in a general way? I know he has a state of the art PC Apple mac
There are keyloggers, and similar, software available that could be used to "spy" on his computer habits but it would take specific working knowledge of Macs in order to gain entry to and install 3rd party software.
Is a keylogger also a password XXXXX? And could ANY kind of access be gained IF the PC is logged off? he has set it so that if it is logged off then the password XXXXX to be typed to log on again.
His PC is more than year old i think - but is there any other way he could access this Firmware password? And what is the advantage of it regarding someone trying to guess his PW or use sofware to guess it?
