Thanks so much sky-knight and appleoddity! You have been a tremendous help. I understand that hosts files can be a good thing. Kim Komando has promoted some of them in the past as basic protection. I guess my gripe with Vision is that I started with them and inquired several times about the blocked pages and different people told me it was not their managed services. I actually don't think they were trying to be dishonest. I have concluded that when you call or email support, sometimes it is good and sometimes it seems to be quite mediocre.
Again, thanks everyone for some great help and advice. It has all been very enlightening. God bless.
