Should we use another browser?

I wouldn't say that I know it all but it is clear that Microsoft's products are favourite targets of hackers, viruses etc. just because they are so prevalent. Now, calls from experts grow louder to have a different broser just to lower your security risk - does this mean, we should get back to Netscape, or choose newer systems, such as Mozilla or Opera?

Interesting, how the market plays. There was a time, when the IE was far behind the usage of Netscape and Netscape, in the end, was only rescued, when AOL acquired it. Microsoft seemed unstoppable. And now, the market forces (if you consider hacking and viruses and worms market forces), might force change upon us.
