Have you ran your antivirus? Do you have a program installed that uses this icon? Is the icon located on your task bar of running programs? Sorry for all the questions but these are things we would need to know to have an idea of your problem.
These kind of "attention issues" are usually Viruses or a software update. Have you ever seen this icon info before? It's likely a virus and if your not sure what something is or something strange or new pops up, first rule; don't click on it. That's how viruses execute themselves into your system.
Try right clicking on the icon & see if you have properties. From there follow the path on the general tab/location/and delete. Under description on the general tab will also give you a name of the program. Do a search and see if it finds anything. If there are different names write them down doing a search and deleting each one. This is how viruses can work.
If you feel it's a legit program go to start/run/type msconfig/startup tab/ look for suspisios programs and uncheck them. If your not sure what they are look each up on internet.
