Aaron: If neither your anti-virus or malwarebytes can detect the offending trojan, it most likely means that it has been removed or permanently quarantined. Both of which mean that the trojan will not affect your device. If you are still unsure, you could always bring it in to a repair shop and let them have a look too.
Of course. What do you think an anti-virus is for?
Your computer is safe if Malwarebytes did not detect anything.
