Please accept a slight interruption. If you have tried the logical, how about trying the radical. This is based on current folklore surrounding DNSChanger.Trojan.Agent (an infection removed by SAS).
This computer should be isolated from other computers on the local network (typically attached to a router).
Protect from contamination of unknown origin - if this is not practical, then proceed with scans.
Disconnect all computers from the router (local network). Power cycle the router (remove power, restore power). Connect only the infected computer to the router.
Your earlier logs show found and removed items.
Rerun both MBAM & SAS.
This effort is complete when logs report NO infections/threats, or reporting something it can not clean.
Restart the computer. Scan with HJT.
Posts logs. Report progress & what changes are observed.
