Instant Messaging can pose privacy dangers—take steps to protect yourself

• Keep your IM program updated. Turn on automatic updates if available.
• Don't click on links including pictures that you didn't ask for. Especially don't click on links in a member's profile or away message.
• Disable file sharing. If you must share files, then don't open files until you verify that the sender actually sent it (preferably by email or phone). Be extra careful with files that have the .exe or .scr extension and with files that indicate it's a game.
• Turn on IM protection in your antivirus and firewall programs, if available. If your current antivirus program doesn't have IM protection, you might want to upgrade to the latest version or change programs.
• Change your preferences. Look for the security and privacy options and turn them on. In particular, you should limit who you receive messages from. You may be able to block IMs that are sent simultaneously to multiple users.
• Don't respond to any IM's from people who are not on your "buddy list" or in your address book. If you haven't set your filters to receive IMs only from people you know, consider setting it at that level.
• Don't allow your IM program to accept messages or download files automatically even if the sender is on your accepted list.
• Provide only the required information when signing up for a service. Choose not to share/publish the information you provide.
• Don't give out your password if requested. If you click on a link and it requests your password—don't do it—it's not legitimate. No matter how real it looks.
• Messages are sent in plain text across an insecure network and can be easily intercepted so don't reveal any sensitive information such as passwords, account numbers, and vacation plans.
• Terminate your IM session when you leave your computer.
• Report any problem IM users.
