M - wrong, it means it was deleted - the file was deleted.
Otherwise, it would be "cleaned".
3 things can happen.....
Infected file - viral code removed, file remains
Trojan - there is no viral code because the infection IS the file and the file IS the infection, so the file is deleted - cleaned by deletion
or
Quarantined. It can't be cleaned, you didn't want it deleted so it was quarantined. Generally things like documents you want to quarantine, or file that may later be cleanable by later new defs you'd quarantine. There are times SAV or SEP know a file is naughty, but it is a very important document for the boss, so you don't want it deleted. Quarantine it in case later defs can clean it, and it happens.
Trojans have to be deleted - cleaned by deletion, or files that are corrupted or can't be cleaned.
GOOD files that have viral code inserted are cleaned.
Quarantined files - files that are infected but can't be cleaned now, but maybe can be cleaned and thus saved later.
(been doing this since about 1992 so trust me a bit, eh? LOL )
