Bro Tom. I have IE7 installed but you know me. I'm still a firefox freak

IE7 is a big improvement on IE6 as far as security is concerned, but its the same old story. If you do not have it figured correctly, you may well find the same problems of browser hijacking, spyware etc etc.
Opera is also a good browser and i think the days of having to pay for the browser or having the free version but having ads at the top of the browser, are over. My Opera browser certainly doesn't have the ads anymore and i haven't paid a penny for it.
I did notice someone mentioned the Maxathon browser. If you use that, please be careful. I think i'm right in saying that its a shell of IE and comes with the same vulnerabilities.
