Errors Launching Direwolf20 (v1.0.7)

[Secturis]

I'm running FTB on a brand new computer as a fresh install. I have the latest Java 64-bit installed to the default directory and am launching FTB from my primary hard drive with the path C:\Program Files (x86)\Feed The Beast

When I attempt initial launch of the newest Direwolf20 modpack, the console displays a lot of red text and eventually stops with an unhandled exception. Copy of console data linked here: http://pastebin.com/YAy8p8q4

I haven't tried launching any other modpacks at this time.

*Update*

I tried deleting the ftblauncher in %appdata/roaming and then relaunching fresh from a folder named "FTB" located on the desktop, and it successfully downloaded and installed the modpack and launched Minecraft. However, I now have the issue where as soon as it starts building terrain on a new map, it crashes, giving the following crash report:

Obviously any help would be appreciated.

*Second Update*

I decided to disable ChickenChunks, as it is mentioned specifically in the crash log for every world I try to create, and the game was able to create and load a new world with no issues. I don't know exactly what ChickenChunks does, but it seems like it must have some sort of issue.

Your av program is being overzealous and blocking parts of ftb. Add an exception to your av program for the ftb folder, include sub folders as well, listed above.
