Try sophos home. It's free so if it doesn't make a difference, you haven't really lost anything.
Steve I downloaded this but it won't let me install it until I remove McAfee and I'm not doing that. Thank you though. @mort I will check out the one you posted. I nabbed the culprit. it was some analytics bs cte.exe something. I zapped it.
MalwareBytes and Windows seem to have fallen out, the "Protection Module" of MalwareBytes is clashing with the new fangled Windows Defender and causing system crashes. MalwareBytes can be run without enabling Live Protection but what's the point, it won't find anything until after the malware or whatever has invaded! MalwareBytes are working on a solution, Windows say "not our problem", charming.
