I think a history lesson is in order here.
Netscape was the first widely used graphical interface for the Internet. It was based on an earlier "open source" web browser called Mozilla.
Netscape was not originally "married" to AOL. That did not happen until many years after Netscape had been out. That merger has been the subject of much debate, speculation, conspiracy theories etc etc etc. and for people who had not been using Netscape over the long haul did cause some hard feelings against that browser --- especially in those who harbored hard feelings for AOL (which, in that case, I can certainly understand).
To cut to the chase, the bottom line is that Netscape and other Mozilla-based browsers (such as Firefox) are FAR superior to the Internet Explorer. If you got spyware because of using Netscape, then something else was going on. Web sites do not deliver spyware according to what browser you use. If you are getting spyware then you need to tighten your Internet security.
Regarding email, the newest version of Netscape (9.x) no longer includes an email client. Those who like Netscape Mail (raising my hand vigorously) are obliged to use 7.x for that feature.
I have on my Mac -- Netscape 7.2 (for email) and 9.005 (for browsing); Firefox 2.009, Opera 9.25, Apple Safari 3.04, and Internet Explorer 5.2 (the last version made for the Mac).
I have on my PC -- all the above, minus Safari [it's an Apple-only product], and I do have Internet Explorer 7.x.
I have listed them in the order I use them, with IExplorer a VERY distant finisher on both platforms. Actually, I only use it to test-run web pages I am designing, just as a final spot-check. I never browse with it. Just personal preference, perhaps, along with a lingering resentment over the way Microsoft tried (unsuccessfully) to strong-arm Netscape out of business.
