The last item in the article you linked to above says
• Say no when browsers offer to save your password – Web site browsers like Firefox and Internet Explorer have a feature which lets users save passwords for later use. The most widely distributed password stealing Trojans, including Zbot and SpyEye, know where to look and how to steal that information if you get infected. This also applies if you use an FTP client.
I'm curious if most people follow this guideline. I don't, I'm afraid. I'm the only user on my computer and I have passwords saved in either LastPass or my browser (FF & Opera). I realize I can't ever be 100% sure that there isn't a trojan on my computer that's poised to steal my passwords, but I also can't remember the 30-something character passwords I use for my email accounts. So I end up erring on the side of convenience by letting the browser or LP remember it for me.
