I am going through your logs now. One thing I question; you say you ran CCleaner first and THEN your anti-virus program. CCleaner "should" have cleaned out your internet temp files but the anti-virus program finds trojans in your Internet Explorer Temp files.
You need to navigate to these folders;

C:\Documents and Settings\LocalService\Local Settings\Temporary Internet Files\Content.IE5\HQ3N07CP\

C:\Documents and Settings\LocalService\Local Settings\Temporary Internet Files\Content.IE5\Q2NYU0PG\

C:\Documents and Settings\LocalService\Local Settings\Temporary Internet Files\Content.IE5\XE8XKAS7\

and delete whatever is in those files. Don't delete the files themselves, JUST THE CONTENTS of those folders
