Remember to temporarily disable Defense + when copying the bases.cav. Easiest way to disable is by right clicking on the Comodo icon in the systray → Defense + Security Level → set to disabled. Don’t forget to change the D+ Security Level back to its old setting. Comodo will not warn after 15 minutes or so.
