What precautions should a home user take when using instant messaging (IM)?
• Don’t set your IM client to automatically accept file transfers • Before opening any file received via IM, you should verify with the sender that he or she did actually send that file to you. In addition, make sure the file has been scanned with anti-virus software before opening it • Never click on URL links from untrusted / unknown contacts within an IM chat session • Never send personal or sensitive information over IM.
