Check your Disk Cleanup in Windows. If you have run that recently, the Shockwave Flash Object will be removed if the Downloaded Program Files option is checked. Some AV programs (e.g., MS Onecare) will clean this automatically when Tune-Up is run unless the DPF option is unchecked. If you don't have WLOC (Windows Live Onecare), uncheck this option anyway, as the WLOC Tune-Up "Remove Unneccessary Files" option is simply based on the Windows Disk Cleanup. Unchecking the DPF box will keep Flash intact after a cleanup.
If you have unchecked it already, go to adobe.com, Flash Player section, search "uninstall Flash" and run the Windows Uninstall Technote. Then reboot, and re-install flash.
