Downloaded a Bing bug

I am currently taking a CIS130 Web Design course.

I downloaded some files to complete classwork and now when I go to my aol account to retrieve my messages, the Bing search Engine Pops up after I select my message to read it.

Can anybody help me with this issue. Currently at work and therefore cannot remember the name of the sites I had to download. Oh, I believe one was called Play All for (various types of files) to play and the other was directions for an FTP directions to put my completed web page on the colleges website space for students.
