I certainly would, because from what this lady is saying, Vista's about to become as exploited as XP is now anyway.
Of course, while I do have to be concerned about this for my PC-using clients, I don't have to worry about this at home. I use a Mac, and the worst that a Trojan could theoretically do is trash my user folder. It can't touch the core system.
The same goes for any properly configured Linux system.
Thanks for your advice. I am staying with XP for now.
How safe am I running XP with Firefox?
