Why do all my emails just disappear from my Inbox when I open it?

Over the past 10 days or so, about every 3 days I open my Yahoo Inbox and there are NO emails in it. The first time was a disaster...I had about 2 months' worth of culled messages that I needed to work on. I've also noticed a big increase in spam in my Inbox (plus the usual in my Spam folder). I use Windows Firewall, CA Anti-Virus, CA Anti-Spyware, Ad-Watch (free program), Ad-Aware (free) and have been running Spybot every day or two lately.
