Query: Don't buy this product!

This product is terrible! I've never had a piece of software that not only refused to work out of the box, but actually caused more damage to my system than any virus! I was all excited to install this, due to Norton's reputation for making good products. This is a monsterously invasive program that will take over your computer. Good luck with uninstalling it without formatting your hard drive. I've nver seen such a bad product from what I thought was such a good company.
