I am receiving email with blank boxes with an circle, small camera image in upper left corner. this is received from multiple senders usually in personal email. 

I am unable to open any attachments sent to me. All I get is blank boxes with a star in the corner.

I am on IE 10 and use WIN 7.

 

I also have another issue, where mail disappears from my Inbox!

This is a worry as I have not deleted them.
