Slow loading site

Hi, my site helseboden.com is loading very slow. In the fotter area it displays: “waiting for http://www.fengtech.fr …” is also jump from left to right side when I hover over it.
I have disabled all plugins – but no change.
have tried to find “www.fengtech.fr” in the code with no luck.
I’m running IMSC Flex theme.
