The Avast picked them up…however, upon a restart and a second scan now it is coming up clean. I picked them up in Avast…the Mcaffee found nothing. I keep both as Avast routinely finds things that McAffee misses - for whatever reason. They were PID files. Not sure why this second scan is coming up clean. Do you recommend I rely just on MalwareBytes and MCAffee and delete the Avast?
