Hello Tenna, welcome to the forums !
Here is FYI on your issue:
lsass=Local Security Authority Sub System. This is a part of RPC=Remote Procedure Call. Simply, RPC is a protocol that some programs use to communicate with other programs / PC's on a network, without a hassle of knowing network details.
P.S., I've moved your thread here because its more of a security issue....
HTH
