I have gone into this issue in detail in the thread
https://forum.diabetes.org.uk/boards...y-named.63763/, so I won't repeat the full debate here. However, in summary the thing is that PC Pitstop, who make an alleged anti-malware program called PC Matic, has recently started complaining that Malwarebytes, one of the market leaders in anti-malware software, is now deleting PC Matic as malware; and according to the above thread, and others I have found in a web search, this is because PC Matic
is malware.
