agree with the most of review but cannot consider it a stand Alone AV anymore as it was dedicated for windows 7 environment which became non supported anymore (actually it became integrated in windows defender starting from windows 8 release and keep improving as it became great in windows 10 as AV test and our geeks here testing it and develop tools to make most out of it)
so to be fair the real one should be tested is windows defender not Microsoft essential as it suitable now for legacy OS (XP/windows 7 ) which also have better alternatives)
