There are three users on this XP computer.  Problems with IE7 began happening with two of the user accounts.  The third user account is fine, browsing works perfectly and the following problems don't exist:
1.)  When logging on to ebay the following message appears: "Your browser settings prevent you from automatically redirecting to a new URL"
2.)  On Sirius.com, I cannot get the entire page to load  e.g. pictures, flash screens, logon to internet listening etc.....
3.)  Cannot get Hotmail.com homepage to load (just a white screen)
4.)  Can get into Yahoo mail, but can't open messages or delete messages.
I'm sure there are others as well, but this is a good representation of the problem.
Prior to all this occuring, Norton Internet Security was experiencing a problem...the anti-virus option somehow got shut off and couldn't be turned back on.  I reinstalled NIS and the anti-virus automatic on feature works fine now.  It seems, though, after the reinstall of NIS that these other problems began occuring.  It is strange that one of the three user accounts is seemingly unaffected by all of this.  I did try to create a new user account to see if the 2 problem accounts were somehow corrupted, but the new account has the same problems.  I am baffled and ready for outside assistance.  I've attached a "hijack this" file from one of the "infected" users for your benefit.  I've run complete virus scans and adaware full system checks and found no errors; these are registered programs with Norton and Adaware.  All three users have administrator rights with their profiles.  Been using IE7 for over a year now with no hiccups.  Thanks for your patience and time reading this.
