I kept getting a box come up on my screen telling me it had been blocked. The information in the box was gobbledy gook to me and meant absolutely nothing. But, it would let me in when I clicked to discard the box only for the box to re-appear after a few minutes. I figured for safety it was not worth ignoring it so as said above I switched off. If I'd known it was cookies I'd have gotten a cup of tea to have with them. I missed out on my crisps last night so a cookie in it's place would have been ideal.
