On one of the accounts, when a family member signs in to her Web-based e-mail account, her screen name appears in a small pop-up window just below the input area. The window has gray diagonal lines in the lower right hand corner of the window. The window contains her screen name; the system must have stored it from previous sessions. After entering her screen name, her password is automatically filled in. We are concerned that this brings the risk of others being able to sign on to her e-mail, or to use similarly stored account numbers while shopping. My concern goes further: is that information being sent out to third parties who have no rightful involvement in the session?
It is only happening within her Windows account. Other user areas are not affected. So far. Is this some type of setting that can be shut off, or is there some kind of malware in the system? I have done full system scans using Norton Internet Security, Trend Micro Anti-Spyware (with Venus Spy Trap enabled), and Ad-Aware. Nothing has been found beyond the customary tracking cookies that seem to follow every Web browsing session. These applications are kept up to date. I also keep Windows updated as well.
Thanks for any help you can offer.
