Hi all, I'm not the first to find out, but this malware is so mean it could even waste your Mac. Several websites suddenly tell you that your ADOBE Flash Player is obsolete and 'offer' a new one. DO NOT ACCEPT IT! The trick is that you must give your administrator password somewhere to install it. To avoid any problems: go to System Preferences, click the Flash Player icon below, choose the updates tab, check "Allow Adobe ..." (that's the real one), and to be sure, click "Check Now" to convince yourself that updates are unnecessary. Have a safe 2017. ;JOOP!
