What we discovered today was that the University of Phoenix had an office down the hall and its wireless network was taking over this one computer. With support from BellSouth we switched management of the wireless connection from BellSouth software to Windows XP and all is well. Problem of the wandering browser is solved. Thank you for digging in.
I posted in your other thread as well. You appear to have Personal Security which is a rogue anti-spyware application. You need to remove this app and ensure that your pc is clean as this app also downloads other malware to your pc.

Malwarebytes is effective in removing this application and is free to use.

I will be able to run Malwarebytes tomorrow afternoon. If it catches psecurity, am I then to return to Windows update? How do I manually update the .net file?
I posted the links to the download in your other thread Dave.  

"You can download .net here.

.net 2.0

.net 3.5

.net 4.0

Yeah let Malwarebytes complete the scan, you may even have to scan in safemode.  Make sure the definitions are updated."
Hehe! I'm glad you got that sorted out.
