Norton safe web limit exceeded.

Hi I am new to the community,so would appreciate some help.I use Norton Safe Web reports a lot. I now have a page saying report limit has been exceeded and to enter one of those random character symbols to continue. I had live chat with Norton and was told to do a live update,this didn't solve the issue. I also checked I had the latest product which I have. The Norton rep suggested a remote session to try and solve the problem but I was worried about giving control of my computer to someone else.

Any ideas please?
