I'm currently using IE5.5 and Windows 98SE but am going to put together a new computer soon ....
I've heard that Linux is less vulnerable to viruses than Windows, but presume that some sort of virus protection is still needed. But what about security against other nasties? What is needed? I know nothing about Linux & security issues that might affect it.
First off, just a strong suggestion, but you should really upgrade to IE6 and apply all patches and Service packs that apply to your system, it will make your life (with Windows) easier. I run 98SE also, and believe me, you need to do this.
Then dump IE, and start using Firefox: http://texturizer.ne...x/download.html
Back to the matter in hand.
Linux, like almost all open-source products benefits from not being mainstream. When that changes - and it will - Linux, like Mozilla will come under attack. The saving grace is, that because it is 'open-source', there is no central approach, no 'corporate product', and, by definition, any attack on a Linux system must be addressed to a particular Linux OS, and not Linux systems as a whole.
Also, because the Linux OS is in continual development, the virus/hacker writers are playing a game of 'catch-up'. How do you code for a system that is constantly changing? You could argue that the development of Linux (and other open-source software) mirrors the virus/hackers approach - trying to find new and smarter ways to do something.
Use your normal AV/Anti-Spyware products until further notice, or until MS goes bankrupt.
