I use IE 6 only as I find it excellent. Many people recommend Opera or Firefox.Both can be downloaded free and you can have all three on your machine at the same time, even use at the same time. Give them a try and see how you get on. click here and click here
Use the one you like most. IE is prone to hijacks more than the others simply because it is by far the most popular and therefore the most targeted by malware writers, not because it is less secure. If you stay up to date with MS updates and run Spywareblaster (and Spywareguard if you want) along with a firewall then the chances of a hijack are very small indeed. I always use IE and have never had any problems with it.
ps. although i have all the above browsers installed on my computer, the only one i actually use every day and feel comfortable with is IE6 strangly enough. the others i only just play with from time to time.
