Thanks, Frank.
While waiting for replies, I explored microsoft.com support for IE6, and
found a reference to my problem of takeover of the home page. It suggested
going to IE tools>Internet Explorer options, and under the advanced tab
resetting to the default settings. This maneuver did correct the problem and
I reset the home page option to my preferred URL. Then I locked this setting
in SpyBot Search and Destroy, which prevents automatic change to that
setting. This worked well, but I kept getting pop ups from my WinPAtrol  
program that something was trying to reset my home page. I explored
WinPAtroland found a reference to HKLM Start Page, containing the redirection
phrase I listed in my initial post. I searched for Start Page in regedit, and
found one reference. Rightclicking that allowed modification, and it did
indeed contain the redirection URL. I erased that, put in my desired home
page URL, and so far IE has been working well, no redirection, and no warning
popups ! Thank you all for the various suggestions.
