When you posted that log, am i right in saying you used v1.98.2?, because this is an old version of hijackthis, the newest version is 1.99.0 and you can get it from this link
Here (it may find more stuff)
Also haver you tryed updating windows and IE though windows update, as it appears to be out of date. (

Also i would suggest giving Firefox browser a try as DavidR suggested, as this browser seems to be more 'secure' then the rest.
You can get Firefox from this link
