I just went thru this on my Windows 8 laptop, with Avast.
what I did to fix
1-go to scan exclusions under settings of the scan page of Avast
add this to exclusions: C:\Program Files (x86)\Net-7\bin\LaunchNet7.exe
2- see quarantined list in Avast, restore LauncherNet7.exe and OK out of Avast
3-go to C:\Program Files (x86)\EA GAMES\Earth & Beyond\EBCONFIG, folder.
right-click on enbconfig.exe, run as admin.
***some of my guildies like and use Net7config.exe in same folder, doesn't work right for me***
Set resolution and run the test. OK out of config.
EnB/Launcher should run now
