I currently run MacAfee but find that my pc is slow when starting up while it searches for updates then installs them. After some searching finding Norton coming out on top but did have this a long time ago and found it worse than MacAfee for cpu usage. So was just wondering if anyone had any thoughts or other software that would be usable.
I would recommend you seriously consider Microsofts free security package (AntiVirus/Spyware/Rootkits) due for release shortly, probably when W7 launches or available now in beta from softpedia. It has no detectable impact on performance/boot times etc
