>I think I may have a virus on my computer. Firefox has been acting very wacky for the last two days. For a while it wouldn't respond at all when I clicked its icon in the system tray. Then I started getting this dialog when doing my online banking at chase.com. Specifically, clicking the date calendar icon in the Pay Bills section. Other sites seem unaffected.
