today I was doing my daily check to make sure all my sites were working and happened to glance at the status bar of ie while a page was loading...
the browser was retrieving data from a site I had never heard of and when I checked the source, there were two i-frames inserted into my code.
I posted a support ticket and out of curiosity checked my other sites...
so far five of my eight have also had these i-frames inserted
please check your sites... the i-frames load an amateur porn site!
