That's a lot of icons! It's pretty hard to guess what that program might be. If it starts up at every boot, I'd look in the start menu under startup and see if anything looks remotely like it (perhaps close it, then open the items in startup in turn and see if the icon returns). Also run the registry editor (start, run, regedit), and check these two keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
for startup programs. If you see anything amiss, copy the name of the program into the run box (copy the value of the string* into start, run) to see if it loads the icon again. If you've found it, and it looks like something you don't need or suspicious, just zap that string.

BTW, you can remove the quicktime tray icon if you don't like it. Open QuickTime, go to edit preferences, quicktime preferences. Go to the advanced tab, and uncheck the box about the system tray icon.


* an example so it's clearer:
key name is
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
the string name is
QuickTime Task
and value of that string is
"C:\Program Files\QuickTime\qttask.exe" -atboottime
