Crikey, Amanda, close to 50% of those log entries are bad. And your IE is hopelessy out of date - you'll get slaughtered on the web. AV. Firewall?
Anyway, let's use a good tool to clean out some stuff.
CCleaner
==Get CCleaner from http://www.ccleaner.com/ - and put it in a new folder. You should aim to keep this one for general use. I set it from the installation checkboxes to only open from the recycle bin. It's neater that way.
Now run CCleaner from the recycle bin rclick menu using its default settings [if you set up CCleaner as i suggested, rclicking the bin icon should give you the Open CCleaner option...]. Select the Cleaner icon and the Windows tab; press Run Cleaner. Next select the Applications tab and Run Cleaner again.
==GET AVG antispyware 7.5 here.. http://free.grisoft.com/doc/5390/lng/us/tpl/v5
