I suggest keeping these:
Malwarebytes
Spyware Blaster
You can delete these by dragging them to the recycle bin:
jdk-6u16-windoes
Shortcut to process explorer
Rootkit unhooker
Delete HijackThis via the Control Panel - Add/Remove programs.
Follow these steps to uninstall Combofix and all of its files and components.- Click START then RUN
- Now type ComboFix /uninstall in the runbox and click OK. Note the space between the X and the U, it needs to be there.

Now you should turn system restore off to flush out all previous system restore points, then turn it back on and create a new restore point:
To turn off system restore, on the Desktop, right click on
My Computer and click on
Properties.
Click the
System Restore tab.
Check
Turn off System Restore.
Click Apply and then click OK.
Restart your computer, turn System Restore back on and create a restore point.
To create a new restore point, click on
Start –
All Programs –
Accessories –
System Tools and then select
System Restore.
In the System Restore wizard, select
Create a restore point and click the Next button.
Type a name for your new restore point then click on Create.
