Please help!

Okay, the computer is still messed up, but there are two more clues.

One is that the fafsa review page wouldn't open because it said adobe acrobat was open. Acrobat was not open according to the desktop (and task manager, as far as I can guess at this point... though right now task manager is showing a lot of programs running that aren't, like two open office programs (one .bin, one .exe), plugin-container.exe, HPAdvisor.exe and about a dozen others...).

Second clue is that I was watching a youtube video and navigated away in mid stream. The sound continued. Even after I closed that browser tab.

What the hell is going on? What settings could be messed up? Could it be that flash is completely fubar and I need to uninstall and reinstall adobe?

If you have any ideas about what's wrong, please send them my way!
