Cant recommend Kaspersky enough. Been using if for about 3 years now and i've been throuh all the major players since I've worked in IT. It's simple, doesnt hog all your system resources like norton bloatware and I've never had any security issues since it's been installed, despite the misses using my pc on a regular basis.
AVG is okay, a lot of people I know use it and I've installed it for many people I know who are too cheap to pay for a better alternative
I've also had to re-install it for those same people when I've had to reinstall windows for them after they've picked up various nasties from "gentlemens" websites. I guess you get what you pay for
So you guys will happily pay £20 for a shiney new lure but can't justify the same amount for a years online safety?
Oh and yeah, as Henry said
Firefox not internet explorer, doesn't matter how many time M$ try and patch it it always seems to have more holes than a pair of airflo waders (allegedly)
