I understand that I am not an expert in this field, but decided to read through the 2 Farbar files to pass time. The FRST file flagged up with "ATTENTION (Rootkit)" on 3 specific files. Looking at these 3 files, they appear to have been remnants of an AVAST install, that had been un-installed. Re-starting my PC, and re-using Farbar how now produced a FRST files with no "ATTENTION" flags. However, there are still 2 flags in the Addition file, which appear to be linked to ASUS.
I thank any expert that can confirm my findings, or identify a legitimate Trojan if present.
Kind Regards.
