Error messages on reboot

I am getting the following error message everytime I reboot my computer.

Windows Registry Error:
"One of the files containing the system's registry data had to be recovered by use of a log or alternative copy. The recovery was successful."

This message pops up on every reboot and it is also taking a long time for the icons to pop up on my screen.

Also, when the computer does boot up I am getting two Internet Explorer screens popping up. The address's of each are:

http//63.246.131.130/car.html
http//63.246.131.130/index.htm

Plus, I have tried updating to service pack 2 and I get the following error message when trying to use Windows Update:

Update for Background Intelligent Transfer Service (BITS) 2.0 and WinHTTP 5.1 (KB842773)

I also set up for automatic updates but when I checked under properties on My Computer it still shows Service Pack 1, even though add/remove Programs page shows several Windows Hotfix's with (SP2) in the title.


Thanks,

Shannon
