It was caused by one of your recent Windows Security updates. The following

The answer is from an MS MVP.
---That (tilde) file is most probably appearing as the result
of installing the "April 2003, Cumulative Patch for Outlook
Express (330994)". Microsoft is aware of the problem and is
supposedly working on a fix. Many people are experiencing this
problem and from what I've read about this problem, that icon
will also reappear when you reply to an e-mail and you have
your Outlook Express set up to enter the person's e-mail
address to your address book whenever you reply to an e-mail.
You can either just put up with it or follow the uninstall
directions for the patch at the link below.
