Just would like to know what you(anybody) felt about the subject.
Which seems to protect the computer better? Is it a good idea to use them both or do they conflict, or is there something better altogether.
Thanks.

Running 2 Antivirus at the same time will conflict.
As to which is better, that's a personal decision.

Here's a couple of good, free, ones:
AVG Free
Avast

One antivirus

One Firewall

As many antispyware apps as you like

I use avast myself, If I had a choice of either mccafee or Norton I'd choose mccafee but seeing as there are free av apps out there which work fine there is really no need to pay.

I have had personal experience of Norton missing a trojan on my pc that avgfree picked up. Therefore I wouldn't touch norton again.

There really is no need to pay for any security apps as there are many free ones out there which have keep me problem free for quite some time now
