Outlook messages are vanishing

Hi

I have a peculiar problem…. I have Outlook 2000 installed on a Windows 2000 (sp3) machine it was working perfectly. I have some folders created below the Personel folders -> inbox where i will have my messages grouped on subject wise.

Suddenly a month before all my messages vanished from the subfolders. Yes it is vanished, I didn’t do archive, i didn’t delete ? But messages vanished. I lost all my data, i tried importing my archive pst file also nothing there. So again I consoled myself and started using and again today the same thing happened again.

If you say it may be a VIRUS…. I have Pc-Cillin 2002 runnign on my machine with latest pattern.

So what could be the problem ?
