Quite a lot of services by CNET. Download.com, forums, reviews. There's policy on both and it depends on their reviewers on what they wish to review.
I don't know what version you have that didn't work in your computer but I have NIS 2007.2 that works great in Vista. I even tried it in XP last year NIS 2007 (not build 2) with no problem.
After 7 weeks of working without trouble my Norton Internet Security 2007 software has crashed my new computer. Actually the software quit working and Symantec's automated answer was to completely remove their software then reload it again. They even offered a special software program to handle this for me. Now my programs are crippled or not working at all and Symantec (so far) is useless in finding a better solution than reformatting my hard drive and spending endless hours reloading the operating system & programs. This is not the first time I have had to perform this full reconstruction due to a Norton security product. Rest assured it will be the last time. Perhaps someone from CNET can explain why they have endorsed this product. Based on my experience it is too costly.
