Looks pretty but that's as far as it goes!
Over the years I've been forced to administer McAfee AV among other things.
I personally think McAfee's detection is crap! I've had so many conversations with senior tech and management within McAfee asking them how come free tools on the internet pick it up but you don't??
Each time there was a awkward silence and some bum shuffling followed by the same old "we'll look into this", it never happens. Malwarebytes is much better and cheaper!
My company are now with Sophos, slows the pc's down still but at least it picks stuff up!
