SCRNCAM.EXE & red cross instead of pictures.

Hi.
I have asked these two questions before but never seem to get anywhere so, i will try again.

Question 1). When i try to open an attachement in an e-mail that has a small music video or film in it, i keep getting told that it can not open because SCRNCAM.EXE can not be found, how do i get this scrncam.

Question 2). When i open certain webpages, for example E-bay, instead of pictures being downloaded onto the screen it is replaced by a white box with a red cross in the top left hand corner, how do i stop this happening.

This is my computer.

IBM 267 Series

Thanks.
