Before I go to virus' let me update. I uninstalled Norton 36 using their removal tool; I installed McAfee Security Suite from AT&T Uverse site. Scanned computer; it found 4 trojans, and 2 high risk problems. I then removed the trojans and hig risk items using their options.
The same problem returned when I rebooted.
While the failure to load message as on the screen, I went to the task manager. Under Applications I right clicked the item (failure to load), an option window popped up with an option "Go to Process. That pointed me to rundll32.exe After reading what that does, I think that is where the problem is.
Now what?
