Rick, thanks for your help as always. The PC is definitely still infected, as the browser (FF or IE) redirects me every time I click on a search result. I was able to arrive here after typing rangerland.net into the address bar.
MBAM and SASW found nothing (SASW actually found a bunch of cookies). My AVG scan also found nothing. I am going to run Spybot, but first wanted to post my HJT log.
