Spam problem?

using NIS 17.1.0.19 & outlook 2007. For some reason, spam to me is not spam to NIS - even tho I report it as spam everytime it comes in… I’m getting some virus alerts from which I tried unsubscibing - but it didn’t work for some reason lol and since, I’ve been selecting it as spam - but every time the email comes in - it’s not even moved/removed… looks like the report as spam feature is useless as it does not work - you cannot teach your NIS anything ;/ any ideas?
