Well, I used to have norton installed on my computer, more precisely the Norton Internet Security 2003 (AV, FW, ...)
My opinion at the time, was that it was a pretty good software, that protected my pc. There was not a simgle email that came with a virus without norton to step on first to clean up the mess.
About the firewall, it seemed to be a pretty good piece of software by itself.
The subscription was for a year, and so I had to upgrade after that, maybe to NIS2004 ... but instead of just going out there and buy a licence, I posted on AT at
this thread. You can check the replies I had, and maybe you'll change your mind about norton ... it's not that bad of a product, but you have many alternatives around, as good or even better than norton.
Personally, I went with the
Panda Platinum 7. It has AV and built in Firewall.
I would prefer to use
Kerio Personal Firewall, but after installing it didn't work quite well ... no problem with the kerio itself, but some other software (probably panda) was keeping it from working as it should.
Rest assured, on next re-format, I'll start with Kerio from beginning ... then probably panda just for AV (not firewall).
When you install the panda, you have the option not to install firewall, so you can use another one around ...
