I got a problem on my parents computer. They use Outlook Express for their email client. No for about the last few days, the messages just keep disappearing from their mailbox. We would just watch it and they would all just vanish. I have scanned and scanned for malware, I came up with nothing, so I am coming here. They are running Windows XP Home Edition SP2. I have provided a SS that I find interesting. It shows my mom has 543 total messages, but only 43 show up in the actual inbox. Soon those 43 will dissappear as well. I have looked but can't find anything.
