Scans Don't work All the time

Again, for the second time for this product (Norton Security with Backup) won't allow me to to use the scans on Norton itself. So no quick scans at all but I can scan individuals files just fine. I made post before one time but than it got fix and start to work again. To my surprise though, again it won't allow me to do a scan. So far turning off my computer as done nothing. Everything else works fine such as Live Update. 

It would be nice if this type of thing doesn't happen. I kind of need solution but it did got fix last time after making post on here with no reply so I couldn't give it solution or delete. So this time I will put under 'sharing information' because this does need to be fix.
