Update your Flash player
Adobe (Macromedia) Flash is ubiquitous on the Web. Many sites have banners and other types of ads that use it. It is also used to make multimedia presentations. I use it extensively in creating educational material. Most browsers come with a plug-in or add-on to play Flash. Periodically, security holes are found in the player and updates are issued. Another update has come out recently. Depending on your settings, you may have already been updated but you should check to make sure. Go to this site to check what version you have. Both Firefox and IE should have version 9,0,16,0 installed. If you have an earlier version, download and install the free update.
