Malwarebytes recently detected a PUM on my DEll 15 inspiron windows 10 64 bit laptop.I deleted it but on the next day it returned. I have now deleted it 4 times and its returned every time.Ran Rougekiller and it too deteted the PUM and removed it but it returned. Also an empty folder appeared on my desktop which said "this folder was put here to help you . Simply leave it here." I deleted it but now wonder if its involved with this PUM i can't get rid of. I would be very grateful for any help or advice as i am getting nowhere by myself. The PUM says ...optional\nodrives\policy software..The only thing I have downloaded lately is Cyberreason Ransomefree. Thanks Bob..
