First thing you should only have one antivirus program installed, as multiple can cause problems. Uninstall Norton its basically useless anyway, also ditch AVG. Avast is the best of the lot and will do fine on its own.
Your versions of Java are out of date and should be updated.
I'll leave the HJT log for someone more knowledgeable with them like Speedy.
EDIT: Once you uninstall Norton's download CCleaner links in my signature and run that to remove any traces. Just noticed you already have it.
