Your hate for all things Microsoft is already on record.
ON the other hand, I’m one of those that is pretty happy and trouble-free when it comes to my usage of Windows (any version) and IE.
Trojans and spyware and viruses are things that don’t bother my computer much, and when they do try to invade my computers, they’re caught by IE and my anti-malware software. Perhaps you need to try harder in making your computers “worry-free”. Nothing is going to guarantee that computers are completely worry-free, but, the basic precautions should be enough to keep you out of trouble.
I use FF and IE, and once in a while, Opera. But, I keep coming back to IE, because, it’s still the most secure browser and the fastest around. That’s been confirmed by many security gurus and by benchmarks that tested the more popular browsers.
The one browser which I will never trust, is Chrome, where it’s mere existence spells spyware. All things from Google are spyware, and I value my privacy and my personal data.
