your log say " NO ACTION TAKEN " did you click the remove selected button after the scan ?
if not scan again and do, so the infection is quarantined…
have this solved your problem ?
Yes i didnt yet confirm the removal am aware to remove anything maybe if u can tell me which to delete or delete all that would be great
Thanks
let Malwarebytes quarantine everything.
it will stay in MBAM quarantine so you can restor if somethings goes wrong. Something that is very rare with MBAM
after 30 days you delete it from quarantine
OBS: there have been updates since you scanned so remeber to update before you scan again… 
Pretty Great … Lots of Thank
