Uninstall Java
C:\Windows\System32\Macromed\Flash
Go to that directory and delete the Flash folder. You may not be able to delete it, if not open Hijackthis, click none of the above just start the program, click config, misc tools, delete a file on reboot, browse to the directory I posted about, select the flash9c.ocx and then reboot.
If you cant delete it with hijackthis, reboot into safemode.
After you reboot, check to make sure the flash directory is empty, if its not, delete everything is it. Then go to
java.com: Hot Games, Cool Apps and update to the latest version and then go to
http://www.adobe.com/shockwave/downl...ShockwaveFlash to download the latest version. After you complete this, reboot and then try to access Bebo and Myspace, etc.
