This has to be your own choice. A lot of people on the site will recommend the freebies. But if you do a search here click here you will see that Grisoft do not come out of it very well compared with Norton. You have to ask yourself 'what can I get for nothing?' I use Norton Utilities 2003, and Norton Personal Firewall 2003. If you decide to go along this path it is better to buy them on CD, rather than a download, so that in the event of problems on your computer later, which could involve a reinstall of Windows, you can then reinstall Norton from CD. The choice really is yours, but you must have some protection, even if it is second best.
