Greetings folks, This thread is not a report of any of my PC's being infected by the current 0-day exploit/threat but more of some needed clarifications of suggested mitigation options. Reference: http://www.techspot.com/news/32823-zeroday-exploits-revealed-following-patch-tuesday.html Doing some quick research, it seems the best workaround (until MS provides a security update) is to enable DEP. However, if I remember right, DEP came as part of Xp's SP2 (and I'm assuming SP3) but it had four options: "OptIn" which I believe is the default setting "OptOut" "AlwaysOn" and "AlwaysOff" Just by the sound of it, "AlwaysOff" probably is not the option to choose as a workaround. That being said, of the remaining three which is the best to use while still having full functionality of a particular system and/or websurfing? Also, what exactly would that zero day exploit do if one were to be infected?
