Thanks for the swift comment. Am I therefore safe in assuming that if such an "idle" threat were to be executed manually, then Malwarebytes would indeed detect it? Problem would surely arise though that without the "protection" of the upgraded version, this would still get onto the machine, where Malwarebytes would pick it up and correct it on the next scan. Is that correct? Sorry to be a bit obtuse about this but it seems to me that the AV would be useful to pick up a "possible" threat whereas Malwarebytes would eradicate an existing one. Is that it?

My AVG subscription is almost due and I have been recommended Malwarebytes. Naturally I have thus tried the free version in the first instance but have come across a situation which I am not happy about. AVG picks up a Trojan - Generic12 ASFU which has found its way into a folder called "resycled" (spelling correct!) and is a file called boot.com. An internet search on this item confirms it is indeed malware. However, running a quick and full scan with Malwarebytes fails to find this at all, which is clearly giving me concern. Reading previous posts you suggest that Malwarebytes will not necessarily pick up any "nasty" that is just sitting idle in a folder, as this appears to be doing. However, as the free version does not have "running protection" then surely this Trojan could be activated between scans - hardly a safeguard. It seems to me that malware, even sitting idle, should be detected and removed BEFORE it can possibly be activated. I cannot yet see why I should purchase Malwarebytes with the concern I have. At least AVG spots it and removes it pronto, even if it is lying "idle". Some observation on this apparent problem, and indeed if I am expecting too much from Malwarebytes, would be welcome before I consider upgrading to the commercial version.
