Just an update:
I've decided to use the new Nod32 ESET AV suite and am very happy with it's performance, I've been using it now for well over a month.
Thanks everyone for your suggestions, I also tried ZoneAlarms Pro which was excellent too but I preferred Nod ESET.
Easy to setup and unobtrusive and doesn't seem to be bloatware.
Great anti-spam filtering and top notch firewall.
I actually ended up buying it through a dealer here on IIS.
Also found a link to enable me to completely remove my old installation of Norton's.
If anyone ever wants to remove Norton's completely, visit and follow the instructions:
