I use MBAE on all of my Windows installs, uses minimal resources & one can see it's active (even the Free version, which I use) by the pop-up when opening a browser. One can also right click onto the MBAE icon & then choose to show it, there's a little green area that says it's running.
Nice little app to have, giving protection at launch of browsers, as well as add-ons (extensions) of major ones, and of course Java if installed. For PDF readers, Media Players & MS Office protection, one has to pay for a Premium license after the 14 day Trial period. Those who uses these apps a lot and are concerned about enhanced protection may wish to consider purchasing the Premium license. One can catch the 3 PC/1 Year licenses at promo pricing on the Newegg site, if signed up for promos on their site, where I got all of my MBAM Pro Lifetime licenses at deep discounts (under $15 each).
My opinion, since it uses very little resources, and the large majority of us needs to use our browsers, MBAE is a great product to have installed to help prevent the type of attacks that quiteman7 listed above & is upgraded regularly. Basically an install and forget app until an updated version is released.
For more about MBAE with information, including a 14 day Free Trial, check out the link below. Though I recommend if purchasing, grab from Newegg when on promo, for those who doesn't want to deal with recurring subscriptions, an issue brought up over other security & software choices on this forum. Plus one can often get protection for 3 computers for the price of one listed on the MBAE site.
