Post layout/ Archives Category

Hi there
I am setting up my blog website ” housesittingtailscyclingtrails” Using the enigma inferno theme and I am having problems with the archive category widget keep appearing on my blogs. Even though I have not selected it in widget setup. All I want to do is view blogs right across the page ( as I have set up for some of my pages- see about us- for example) so that no category widgets ( including archives) appear on the site, just the blog information.
Also, when I retrieve a blog from category widget- Australian Tails, I get the heading category archive Australian trail, where all I want to see is Australian tails!
Can anyone help please!
