As a starter I use Win98 now as it were obsolete from Microsoft point of view. But did not have a Problem with MSBlast worm as this was targeted at XP etc. Instead of MS Office I use WordPerfect 2002 that does not have Macro's running all the time, only when needed to use Templates Macros another Virus target. I use Netscape 7 less of a Target than IE and Outlook Express all these are what the masses use. If you was a Virus writer who would you target???????
PS I am not running MS down or trying to, just trying to make a point.
