I noticed the recent influx of virii being discussed and sent across the web. As well as disscussed here. Most of my clients run Outlook. As well I run Outlook on my XP machine. This is a nice way to protect yourself. As I myself only deal with plain text, scan all attachments, don't open anthing I'm not expecting and use PGP sigs. Here is a link to a .dll that will disable html and html scripting in Outlook. I won't go into detail because it's quite long. So here is a link. Hope this helps all. I use it on all my clients networks now.
