I have run the uninstaller for java, verified that all remains were gone, even after reboot. Also tried CC cleaner uninstall. used MBAM and SASP and AVG free all up to date and all found nothing, except the usual few adware pups, no Trojans, viruses. Still no luck after this. Have tried from the java site and also the offline install. I think it's some of the settings for java on the advanced page, I haven't touched any yet, all default. Maybe run yet another round of scans...
