flash player

I don't have any picture at all just a white box with flash content square in upper left corner and that is it. Even after a fresh install when it says when you see the completetion movie flash player is loaded, their is none. I'm sorry if my responding is taking some time but I have gotten hit with some stupid viruses. Mostly fixit software telling me my system is infected and I need to fix it by downloading their program. " Ultimate Defender" is the name "pcprotect" part of product. It has somehow loaded into my system and now matter what I can not delete it, and when I do it just comes back, so I'm working on that now,. Stupid windows securty alerts.
