Supposedly a new realtime detection engine. Much improved (and largely re-written) engine. New notification system is also in place I have been told. Vastly reduced CPU/Memory usage to go along with this. http://www.winpatrol.com The product (for the time being - maybe not for long) is still a lifetime license for a single PC, and a friends/family lifetime license is still available for all PC's you own, or claim to own. 50% coupon code is "friends", which makes the license $14 (lifetime) for 1 user. Or $24 lifetime for 'unlimited' users on PC's you claim to own.
