Hello Antoniertta,
My apologies for the delayed response, your thread was converted from General Discussion to a Question. I'd start first by getting some assistance for your subscription issue, then when that is resolved, I would post a new thread for your updating issue in the AntiVirus/AntiSpyware forum. Below is an response from Steven Boots which should be very helpful. This was given to another user who had a similar issue.
