Can someone tell me what program they use to password protect their laptop?  I do not do this as i heard this process is not that simple.  I heard there is either veracrypt or bitlocker.  Are those the only 2 options or best 2 options?  If so, which do you choose and with it, does that mean a thief with access to your laptop cannot get into your laptop and store anything in it like trojan unless they have the password?  Because say someone installed a trojan in your laptop while you are not there for a bit... let say its just a friend who did it b/c they know you have crypto... that is dangerous.  Any advice here?
