my homepage keeps getting changed

Could someone help my fine the correct files to delete. I have tried deleting the files that are labeled "obfuscated" because that riviera site is the one it's getting directed to. Here's my hijack log and thanks in advance for checking it out.

Download CWShredder:
http://www.spywareinfo.com/~merijn/files/cwshredder.zip
Unzip, run and hit the ->fix tab to fix all found problems

CWShredder takes advantage of seurity holes in windows so you should install all critical as well as hotfixes available from windows update.


Then repost a fresh Hijack this log .

Download 'Hijack This!'. http://www.tomcoyote.org/hjt/ and save it to a folder on your desktop.
Unzip, doubleclick HijackThis.exe, and hit "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log, load it in Notepad, and copy its contents here. Most of what it lists will be harmless or even essential, don't fix anything yet.

 

thanks, I did the above and here is my new log
