You need to update your Java. You are currently running version 6 update 5 and the most recent version is update7.
Go HERE to download the latest version. Choose the Offline Install version and save it to the desktop. Once that has downloaded close the browser and go to Start, Control Panel, Add/Remove. Uninstall all previous Java versions showing. Once those have all been uninstalled then go back to the desktop and double click that Java icon to install the new version. After it is installed then go to my link above again and on the right side of the page you will see Verify. Click there and verify that the newest version installed correctly.
I also would advise that you uninstall AdAware 2007 via Add/Remove. It just isn't the program the previous versions were. Use instead Spybot Search & Destroy...but DON'T use the TeaTimer portion of the program. Also another must have program is SpywareBlaster.
It is also free and provides excellent protection against
ActiveX-based spyware, adware, browser hijackers, dialers, and other potentially unwanted software.
Block spyware/tracking cookies in Internet Explorer and Mozilla Firefox.
Restrict the actions of potentially unwanted sites in Internet Explorer.
an added plus for this program is that it doesn't run in the background.
Do you feel your problems are corrected? If so then set a new and clean System Restore point following the directions given HERE
