I was searching the internet. Using paypal and MSN. I was also logged into a Java based game called Runescape. The above icon popped up in my dock for literally half a second than disappeared. I have seen the icon before usually when running Java programs or dual platform (Windows/OS X) programs. First thing that came to mind was a keylogger/virus. Should I be worried? Anything I can do to try to find out what it was? I am on a 2007 iMac 20" if that helps at all. Any help is greatly appreciated.
