A new threat to AOL instant messaging users is making the rounds.  IM users will get a message with a misleading link. When they click the link, a malicious file will be executed on their windows system, allowing the computer to be taken over remotely.

ZDNet News reports that ,"Pipeline initially appears as an instant message from a familiar contact, according to FaceTime security. A message appears asking users to click on a link to upload a picture of themselves; instead, a command file, image18.com, is downloaded and disguised as a JPEG, according to FaceTime."
