My HP laptop has done the same thing since I got it. went thru the filter delete and everything else and like yours it cycle...IE6 is vulnerable...IE7..saved me from IE8 whIch frankly was like watching grass grow if it loaded at all and now the 7 is doing the same thing... won't load.. slow as crap.... Solution? MICROSOFT FIX YOUR CRAP! and stop loading up my computer with your updates just make the sh_t right to begin with since you have all that money MAC! which has no registry and comes on imediately when fired up.
