Norton is evil! Uninstall it this instant, if you can. There are many free antivirus software programs available that in our opinion work better, besides being free. There are ways to tell Norton to ignore the folder you store the bot and the The Director in, adding exceptions to its database, but it is our opinion that Norton does a great job of slowing your computer down. Who wants a slow bot?

It's free, it does everything you need and you don't need to get the ones listed above.
