In terms of the frequency of getting hit with malware, backdoor trojans, virus, worms and all that stuff...how much of a difference would it make to replace IE with Firefox and OE with Thunderbird? I've got Norton, Zonealarm and all the necessary Windows updates except one which rendered Excel useless to me and still got hammered last week with a backdoor trojan which disabled Nortons LiveUpdate and access to their site among others. I'm fed up with this stuff, but going to a Mac or Linux isn't an option at this time. If making these changes would be helpful, is there anything I need to know about removing IE and OE? I've heard horror stories about uninstalling these things. Thanks for any info provided!
