I have a feeling this one will challenge you senior techies out there bigtime -- about 2 weeks ago my IBM T21 just started spinning the hard drive CONSTANTLY whenever I would visit Yahoo sites (my mail server, for one thing) using IE6. Most all else works fine, except whenever I'm on Yahoo, the hard disc starts to grind away and it takes 5 - 30 minutes just to bring up a page, or to bring up the task manager.
About the same time this started I noticed I couldn't run Netscape 7 OR run my Norton/Symantec AntiVirus. I downloaded Ad-aware, Advanced System Optimizer, defragged the hard drive, defragged the system registry, etc. This fixed some problems with bootup times -- but IE still hosed on Yahoo. Went to Microsoft and downloaded every conceivable patch for IE6. Nothing. Loaded IE5.5 - same problem. Loaded Netscape6 -- SAME PROBLEM!! Went to the Symantec website and ran all their utilities and everything checks out "stealth". Their virus scan gave me an A+. Problem still there. Ran SpyBot S/D last night - found some stuff, deleted it. (SpyBot even deleted the stuff when I pressed "no" button... hmmmmm). Rebooted -- NO HELP. So Finally I got hold of HijackThis and ran it -- doesn't look unusual to me. Logfile is attached. I'm running IE 6.0.2800.1106.xpsp1.020828-1920 with SP1 and a bunch of Q... patches. Note: I can do most anything with this laptop and it works hunky-dory, including surf NON-Yahoo URL's (occasionally I will find one that hangs slightly, but nowhere near yahoo). And as you might guess IT IS DRIVING ME CRAZY.
