I know nothing of BT Openworld, its products, how to install/uninstall, but if you don't need it, I would suggest you kill it. Somewhere something is trying to get you to call mother
.
Google produced info for eyebeam and in view of your ref. to Skype I would guess you are playing with VOIP? Again, get rid of what you do not need.
Most
decent programmes have uninstall features
. Try their web site/ help pages if you are stuck. There are other ways of getting rid of things, but best to do it the 'proper' way to start. You will probably shortly get advice on BT Openworld, Skype and Eyebeam. Stay tuned!
Perhaps look at the 'hijack this' sticky here? That may give you extra info.
