Windows .exe FTB-Unleashed Error

[Steampunkperson]

So I download the unleashed mod-pack and when it gets to the FML bit, it works for a second and then says "There was a fatal error starting up minecraft and FML Minecraft cannot launch in it's current configuration Please consult the file C:\FTB\Unleashed\minecraft\ForgeModLoader-client-0.log" So i go to that file and it says:

This is usually caused by an over zealous antivirus program. Add the folder, 'C:\FTB\', to the exclusion list in your antivirus program. Be sure to check any box that says include sub-folders so it applies to all the packs not just the launcher.
