Query: It's a pleasurable product

I installed without any problem because I delete all of programs and reinstall win XP in my harddisk before installing the product. It's compatible with WIN S Pack 2 indeed. I think the problem of Norton software always happen because it easilly cause software conflict. NAV is great. Pretty much better than Mcafee, Panda and so on. The scanning is fast and efficient. However, I do agree with you that the support and its troubleshooting is bad. Sometimes, it's useless
