Hello,

From your log it seems that you actually do not start the updates at all.

Do you have a Firewall?

Can you try if you can reach these sites?

http://spybot.gehirnbrand.de/updates/spybot2files/.
http://www.spybotupdates.biz/updates/spybot2/.
http://www.antispyware-downloadserve...dates/spybot2/.
http://134.169.192.5/pub/mirror/spybot.info/sb2updates/.

Or maybe Norton ist still blocking it and you only have allowed Spybot, but not the update service explicit.
The update is being done by two services (SDUpdSvc.exe und SDUpdate.exe), maybe only one is whitelisted.

Best regards
