To start with, Have HJT fix the following:

Once done, reboot into safe mode and delete all of the files referenced in the above log entries. You might have to set WIndows Explorer's "View" options to show all files and folders, show hidden and system files, etc.

You might also want to have HJT whack these as well:

O9 - Extra button: Research (HKLM)
O9 - Extra button: Related (HKLM)
O9 - Extra 'Tools' menuitem: Show &Related Links (HKLM)

Once all of that is done, purge your cookies, Temporary Internet FIles, and History. Empty your Recycle Bin after that.

It seems to be working and fixed now. Thanks. Now how do I prevent this from getting on my computer again?

There are general "best practice" steps you take to lessen your chance of reinfection, and there are also a couple of programs you can download which will actively block some spyware activity. All of this is described in the following article; give it a read:
