Somehow I got infected by trojan.killerav and NOD32 didn't notice it. Ran the free version of Malwarebytes and it detected and removed without any problem. I never clicked on the actual: x.exe (Trojan.KillAV) so I assuming it must have piggy backed in with another piece of software. Just curious as to why NOD32 didn't catch this old variant of a threat? Thanks for any input.
